- Serialize selection type and ranges with SCI_GETSELECTIONSERIALIZED and SCI_SETSELECTIONSERIALIZED.
- For Win32, update Direct2D and DirectWrite interfaces used to 1.1 and add a lower-level approach to calling DirectWrite 1.1 by specifying SC_TECHNOLOGY_DIRECT_WRITE_1. Since Windows Vista does not support these API versions, Scintilla o longer supports DirectWrite on Windows Vista and will fall back to using GDI.
- Fix segmentation of long lexemes to avoid breaking before modifiers like accents that must be drawn with their base letters. For wrapping, try to break lines without separating letters from modifiers.
- For GTK on Windows, replace reverse arrow cursor with hand as reverse arrow was small in scaled modes. Bug #2460.

- Can set font used for autocompletion lists with SCI_AUTOCSETSTYLE. Feature #1523.
- Increase maximum zoom set interactively to +60 points. Feature #1517.
- Fix flickering cursor after some mouse action sequences. Bug #2443.

### Release 5.5.0

- Released 23 April 2024.
- Add elements for inactive additional selections SC_ELEMENT_SELECTION_INACTIVE_ADDITIONAL_TEXT and SC_ELEMENT_SELECTION_INACTIVE_ADDITIONAL_BACK. When not set these default to SC_ELEMENT_SELECTION_INACTIVE_TEXT and SC_ELEMENT_SELECTION_INACTIVE_BACK. Bug #2417.

### Release 5.4.2

- Released 5 March 2024.
- Significantly reduce memory used for undo actions, often to a half or quarter of previous versions. Feature #1458.
- Add APIs for saving and restoring undo history.
- For GTK, when laying out text, detect runs with both left-to-right and right-to-left ranges and divide into an ASCII prefix and more complex suffix. Lay out the ASCII prefix in the standard manner but, for the suffix, measure the whole width and spread that over the suffix bytes. This produces more usable results where the caret moves over the ASCII prefix correctly and over the suffix reasonably but not accurately.
- For ScintillaEdit on Qt, fix reference from ScintillaDocument to Document to match change in 5.4.1 using IDocumentEditable for SCI_GETDOCPOINTER and SCI_SETDOCPOINTER.
- For Direct2D on Win32, use the multi-threaded option to avoid crashes when Scintilla instances created on different threads. There may be more problems with this scenario so it should be avoided. Bug #2420.
- For Win32, ensure keyboard-initiated context menu appears in multi-screen situations.

### Release 5.4.1

- Released 27 December 2023.
- Add IDocumentEditable interface to allow efficient interaction with document objects which may not be visible in a Scintilla instance. This feature is provisional and may change before being declared stable. For better type-safety, the ScintillaCall C++ API uses IDocumentEditable* where void* was used before which may require changes to client code that uses document pointer APIs DocPointer, SetDocPointer, CreateDocument, AddRefDocument, and ReleaseDocument.
- Ctrl-click on a selection deselects it in multiple selection mode.
- Add SCI_SELECTIONFROMPOINT for modifying multiple selections.
- Add SCI_SETMOVEEXTENDSSELECTION and SCI_CHANGESELECTIONMODE to simplify selection mode manipulation.
- Improve performance of global replace by reducing cache invalidation overhead. Feature #1502.
- Fix regular expression search for "\<" matching beginning of search when not beginning of word and for "\>" not matching line end. Bug #2157.
- Fix regular expression search failure when search for "\<" followed by search for "\>". Bug #2413.
- Fix regular expression assertion (^, $, \b. \B) failures when using SCFIND_CXX11REGEX. Bug #2405.
- Fix regular expression bug in reverse direction where shortened match returned. Bug #2405.
- Avoid character fragments in regular expression search results. Bug #2405.
- With a document that does not have the SC_DOCUMENTOPTION_TEXT_LARGE option set, allocating more than 2G (calling SCI_ALLOCATE or similar) will now fail with SC_STATUS_FAILURE.
- Protect SCI_REPLACETARGET, SCI_REPLACETARGETMINIMAL, and SCI_REPLACETARGETRE from application changing target in notification handlers. Bug #2289.

### Release 5.4.0

- Released 18 November 2023.
- Fix crashes on macOS 12 and older when built with Xcode 15.0.

### Release 5.3.8

- Released 5 November 2023.
- Fix excessive memory use when deleting contiguous ranges backwards. Notepad++ Issue #13442.
- Fix incorrect substitution when searching for a regular expression backwards. Bug #2405.
- Make SCI_MOVESELECTEDLINESUP and SCI_MOVESELECTEDLINESDOWN work for rectangular selections. Bug #2078.
- For Cocoa, minimum supported macOS release increased to 10.13.
- For Cocoa, fix invisible text on macOS 14 Sonoma. Bug #2402.
- For Cocoa, do nothing for suspendDrawing on macOS 10.14+ as the underlying calls have been deprecated.

### Release 5.3.7

- Released 22 September 2023.
- For GTK on macOS, fix popup window behaviour by setting type hints. Bug #2401.
- For GTK, fix assertion failure on some systems when an INDIC_SQUIGGLEPIXMAP drawn for a zero-width character.
- For Qt, allow parent window to handle context menu events by setting as ignored. Bug #2395.
- For Qt, fix potential crash when using IME with large amount of text selected.
- For Windows, fix building with non-English environment. Bug #2400.

### Release 5.3.6

- Released 26 July 2023.
- Redraw calltip after showing as didn't update when size of new text exactly same as previous. Feature #1486.
- On Win32 fix reverse arrow cursor when scaled. Bug #2382.
- On Win32 hide cursor when typing if that system preference has been chosen. Bug #2333.
- On Win32 and Qt, stop aligning IME candidate window to target. It is now always aligned to start of composition string. This undoes part of feature #1300. Feature #1488, Bug #2391, Feature #1300.
- On Qt, for IMEs, update micro focus when selection changes. This may move the location of IME popups to align with the caret.
- On Qt, implement replacement for IMEs which may help with actions like reconversion. This is similar to delete-surrounding on GTK.

### Release 5.3.5

- Released 31 May 2023.
- On Win32, implement IME context sensitivity with IMR_DOCUMENTFEED. Feature #1310.
- On Win32 remove dependence on MSIMG32.DLL by replacing AlphaBlend by GdiAlphaBlend. Bug #1923.
- On Qt, stop movement of IME candidate box.
- On Qt, report correct caret position within paragraph for IME retrieve surrounding text.
- On Qt for Cocoa, fix crash in entry of multi-character strings with IME.

### Release 5.3.4

- Released 8 March 2023.
- Add multithreaded wrap to significantly improve performance of wrapping large files.
- More typesafe bindings of *Full APIs in ScintillaCall. Feature #1477.
- Fix overlapping of text with line end wrap marker. Bug #2378.
- Fix clipping of line end wrap symbol for SC_WRAPVISUALFLAGLOC_END_BY_TEXT.
- Where a multi-byte character contains multiple styles, display each byte as a representation. This makes it easier to see and fix lexers that change styles mid-character, commonly because they use fixed size buffers.
- Fix a potential crash with autocompletion list fill-ups where a SCN_CHARADDED handler retriggered an autocompletion list, but with no items that match the typed character.

### Release 5.3.3

- Released 8 February 2023.
- Fix SCI_LINESJOIN bug where carriage returns were incorrectly retained. Bug #2372.
- Fix SCI_VERTICALCENTRECARET to update the vertical scroll position.
- When an autocompletion list is shown in response to SCN_CHARADDED, do not process character as fill-up or stop. This avoids closing immediately when a character may both trigger and finish autocompletion.
- On Cocoa fix character input bug where dotless 'i' and some other extended Latin characters could not be entered. The change also stops SCI_ASSIGNCMDKEY from working with these characters on Cocoa. Bug #2374.
- On GTK, support IME context. Feature #1476.
- On GTK on Win32, fix scrolling speed to not be too fast. Bug #2375.
- On Qt, fix indicator drawing past left of text pane over margin. Bug #2373, Bug #1956.
- On Qt, allow scrolling with mouse wheel when scroll bar hidden.

### Release 5.3.2

- Released 6 December 2022.
- Add SCI_REPLACETARGETMINIMAL to change text without causing unchanged prefix and suffix to be marked as modified in change history.
- Draw background colour for EOL annotations with standard and boxed visuals.
- Add SCI_GETSTYLEDTEXTFULL to support 64-bit document positions on Win32 replacing SCI_GETSTYLEDTEXT which is not safe for huge documents. Feature #1455.
- Send SCN_AUTOCCOMPLETED for SCI_AUTOCSHOW triggering insertion because of SCI_AUTOCSETCHOOSESINGLE mode. Feature #1459.
- Change 'paragraph up' commands SCI_PARAUP and SCI_PARAUPEXTEND to go to the start position of the paragraph containing the caret. Only if the caret is already at the start of the paragraph will it go to the start of the previous paragraph. Bug #2363.
- Change release compilation optimization option to favour speed over space. -O2 for MSVC and -O3 for gcc and clang.
- On Win32, avoid blurry display with DirectWrite in GDI scaling mode. Bug #2344.
- On Win32, use the top-level window to find the monitor for DirectWrite rendering parameters. Temporarily switch DPI awareness to find correct monitor in GDI scaling mode. Bug #2344.
- On Qt, implement SCI_SETRECTANGULARSELECTIONMODIFIER for all platforms.
- On Qt, allow string form XPM images for SCI_REGISTERIMAGE.

### Release 5.3.1

- Released 12 October 2022.
- Added SCI_STYLESETINVISIBLEREPRESENTATION to make it easier to edit around invisible text. This also allows representing long lexemes with a single character to provide a summarized view. Feature #1453.
- Removed NotifyLexerChanged notification from DocWatcher. This is a private interface but could be used by independent platform layers and was exposed by ScintillaDocument in the Qt implementation of ScintillaEdit.
- Draw lines more consistently in SC_PHASES_TWO and SC_PHASES_ONE modes by clipping drawing to just the line rectangle. This stops drawing some extreme ascenders, descenders and portions of indicators which may appear and then disappear depending on which lines were drawn.
- Draw SC_MARK_BAR markers underneath other markers as they often cover multiple lines for change history and other markers mark individual lines.
- Enlarge point and point top indicators and scale to be larger with larger text.
- Suppress change history background line shading when printing. Bug #2358.
- Make SCI_LINESCROLL more accurate when width of space not integer. Bug #2357.
- On Win32 implement horizontal scrolling mouse wheel. Feature #1450.
- On Win32 implement horizontal scrolling with Shift + mouse wheel. Feature #749, Feature #1451.
- On Win32 ensure page and step clicks on horizontal scroll bar do not overshoot document width.
- On GTK, fix bug where there were too many or too few lines when wrapping. Bug #2349.

### Release 5.3.0

- Released 27 August 2022.
- Added change history which can display document changes (modified, saved, ...) in the margin or in the text.
- Add SC_MARK_BAR marker and INDIC_POINT_TOP indicator. SC_MARK_BAR is an outlined and filled rectangle that takes the full height of the line and 1/3 of the margin width. To give a connected appearance, it displays even on wrapped lines and draws end caps on the first and last line. INDIC_POINT_TOP is the same as INDIC_POINT but draws at the top of the line instead of the bottom. INDIC_POINT and INDIC_POINTCHARACTER were tweaked to be 1 pixel taller and 2 pixels wider in two-phase draw mode to be clearer. The translucency of INDIC_COMPOSITIONTHICK can be changed with SCI_INDICSETOUTLINEALPHA.
- Improve drawing of rounded rectangles on Direct2D.
- Line state optimized to avoid excess allocations by always allocating for every line. This makes SCI_GETMAXLINESTATE less useful although it can still distinguish cases where line state was never set for any lines. Feature #1441.
- Add SC_FOLDACTION_CONTRACT_EVERY_LEVEL option to contract every level for SCI_FOLDALL. Bug #2340.
- Enable multiline regex for gcc and clang when REGEX_MULTILINE defined. This requires gcc 11.3 or clang 14. Bug #2338.
- Stop including STYLE_CALLTIP when calculating line height. Allows a large font to be used for calltips without affecting text display. Bug #2341.
- Fix incorrect display of selection when printing in some modes. Bug #2335.
- Fix crash on Qt when showing autocompletion and the caret isn't on a screen. Move autocompletion onto screen when above it.

### Release 5.2.4

- Released 10 July 2022.
- Fix hiding selection when selection layer is SC_LAYER_UNDER_TEXT. Bug #2334.
- Fix bad background colour for additional, secondary, and inactive selections when printing. Bug #2335.
- Fix failures on GTK with non-UTF-8 text when multi-threading due to character set conversion code that was not thread-safe.
- Fix crash when printing on Win32 in bidirectional mode with a non-empty selection.

### Release 5.2.3

- Released 22 May 2022.
- Duplicate APIs to support 64-bit document positions on Win32: SCI_GETTEXTRANGEFULL, SCI_FINDTEXTFULL, and SCI_FORMATRANGEFULL. This adds new types to Scintilla.iface which may impact downstream projects. Applications should move to these APIs from their predecessors as they will be deprecated.
- Improve performance of SCI_FOLDALL(SC_FOLDACTION_EXPAND) by not lexing whole document as it does not depend on folding structure.
- Fix partial updates and non-responsive scroll bars on Xorg. This defers scroll bar changes to an idle task so could affect applications that depend on the scroll position being updated. Bug #2322, Bug #2196, Bug #2312.
- Fix problem with horizontally inverted glyphs with buffered drawing and WS_EX_LAYOUTRTL set on Win32 GDI. Feature #1435.
- Fix ARM64 builds with Visual C++ due to unsupported CETCOMPAT flag. Bug #2324.
- On Cocoa, place autocompletion lists and calltips on a higher window level so they can be seen when invoked from a modal dialog. Bug #2329.
- For Qt 6, fix "modified" signal when text is null but length non-0. Bug #2328.
- Fix pink selection background when printing by making it completely transparent.

### Release 5.2.2

- Released 31 March 2022.
- Add SCI_GETSTYLEINDEXAT API to return styles over 127 as positive integers. Feature #1431.
- On GTK, scroll horizontally with shift + scroll wheel.
- Fix crash with unexpected right-to-left text on GTK. Bug #2309.
- Fix position of end-of-line annotation when fold display text is visible. Bug #2320.
- On Direct2D, support per-monitor text rendering parameters. Feature #1432.

### Release 5.2.1

- Released 24 February 2022.
- Enable multi-threaded layout on GTK.
- Fix pixmap leak on GTK. Bug #2317.
- Fix re-entrant painting on GTK to maintain update region.
- Fix key map for GTK on macOS. Bug #2315.
- Fix building for Haiku. Bug #2315.

### Release 5.2.0

- Released 9 February 2022.
- Add multithreaded layout to significantly improve performance for very wide lines. Feature #1427.
- Made compatible with Qt 6.
- Fix potential issue with length of buffer for string returning APIs in ScintillaEdit on Qt.

- On GTK, use fractional positioning to help Chinese characters in monospaced fonts line up better with roman characters. Bug #2310.
- On macOS allow Scintilla to run if built without cursor images. Feature #1425.

### Release 5.1.5

- Released 7 December 2021.
- ScintillaEditPy, Python bindings for Qt using PySide, has been removed. Scintilla was never updated for PySide 2 which was released in 2018 and PySide 1 fell out of support making it difficult to use. Tests that use ScintillaEditPy were removed.
- When calling SCI_GETTEXT, SCI_GETSELTEXT, and SCI_GETCURLINE with a NULL buffer argument to discover the length that should be allocated, do not include the terminating NUL in the returned value. The value returned is 1 less than previous versions of Scintilla. Applications should allocate a buffer 1 more than this to accommodate the NUL. The wParam (length) argument to SCI_GETTEXT and SCI_GETCURLINE also omits the NUL. This is more consistent with other APIs.
- Fix assertion failure with autocompletion list when order is SC_ORDER_CUSTOM or SC_ORDER_PERFORMSORT and the list is empty. Bug #2294.
- On Win32 prevent potential memory leaks for Korean language input. Bug #2295.

- Add SCI_SETCARETLINEHIGHLIGHTSUBLINE to highlight just the subline containing the caret instead of the whole document line. Feature #841.
- Allow SCI_HIDELINES to hide the first line or all lines which can be useful for filtered views.
- Make negative settings for extra ascent and descent safer by ensuring calculated ascent and thus line height is at least 1 pixel.
- Fix display of fold lines when wrapped so they are only drawn once per line, not on each subline.

- Searching was optimized for documents that contain mostly ASCII text and is often 2-3 times faster. Feature #1381.
- Word searching behaves more consistently at start and end of document.
- Add SCI_ALLOCATELINES to allocate indices to hold some number of lines. This can decrease reallocation overhead when the application can count or estimate the number of lines in huge files. Feature #1370.
- Add SCI_AUTOCSETOPTIONS to allow choosing a non-resizeable autocompletion list on Win32. Feature #1284.
- On Win32, when technology is changed, buffering is set to a reasonable value for the technology: on for GDI and off for Direct2D as Direct2D performs its own buffering. Feature #1400.
- On Win32, implement WM_SETREDRAW to turn off scroll bar updates. This can be used to reduce overhead when making many changes. Feature #1411.

### Release 5.1.0

- Released 23 June 2021.
- This is a stable release. Interfaces with lexers and between platform-independent code and platform layers should remain compatible through 5.x releases.
- Add SciFnDirectStatus, a direct access function which also returns status. It can be retrieved with SCI_GETDIRECTSTATUSFUNCTION. This can avoid calling SCI_GETSTATUS after every API to determine failure so can improve performance.

- Fixed gcc link-time-optimization (LTO) compilation. Bug #2259.

### Release 5.0.3

- Released 2 June 2021.
- A more type-safe binding of Scintilla's API that can be used from C++ is implemented in the ScintillaTypes.h, ScintillaMessages.h, and ScintillaStructures.h headers.
- Change the way that selections and carets are drawn to use the element APIs. The selection background colour may default to use platform APIs to discover global or user settings and may change in response to those settings changing. The SCI_SETSELECTIONLAYER method defines whether the selection background is drawn translucently over or under text or opaquely underneath other drawing.
- Change caret line drawing to use SC_ELEMENT_CARET_LINE_BACK element and SCI_SETCARETLINELAYER method. Older caret line APIs SCI_SETCARETLINEVISIBLE, SCI_SETCARETLINEBACK, SCI_SETCARETLINEBACKALPHA now discouraged.
- Add SCI_MARKERSETLAYER to define layer on which to draw content area markers. This replaces the use of SC_ALPHA_NOALPHA for markers.
- Add SCI_GETELEMENTBASECOLOUR to return the default values for element colours.
- Add SC_ELEMENT_WHITE_SPACE to set the colour of visible whitespace including translucency.
- Add elements for hot spots SC_ELEMENT_HOT_SPOT_ACTIVE and SC_ELEMENT_HOT_SPOT_ACTIVE_BACK.
- Make idle actions wrapping and background styling smoother by measuring per-byte instead of per-line and allowing just one line to be processed in a time slice. Very long lines will not distort estimation or block interaction as much. Feature #1373.
- On GTK 3 with Wayland, fix primary selection. Bug #2227.
- Update to Unicode 13. Feature #1379.
- Include modifiers in SCN_INDICATORRELEASE notification. Bug #2254.

- Fix SciTE crash on GTK+ when using director interface.

### Release 4.1.0

- Released 19 June 2018.
- Experimental and incomplete support added for bidirectional text on Windows using DirectWrite and Cocoa for UTF-8 documents by calling SCI_SETBIDIRECTIONAL(SC_BIDIRECTIONAL_L2R). This allows documents that contain Arabic or Hebrew to be edited more easily in a way that is similar to other editors.
- INDIC_GRADIENT and INDIC_GRADIENTCENTRE indicator types added. INDIC_GRADIENT starts with a specified colour and alpha at top of line and fades to fully transparent at bottom. INDIC_GRADIENTCENTRE starts with a specified colour and alpha at centre of line and fades to fully transparent at top and bottom.
- Wrap indent mode SC_WRAPINDENT_DEEPINDENT added which indents two tabs from previous line.
- Indicators are drawn for line end characters when displayed.
- Most invalid bytes in DBCS encodings are displayed as blobs to make problems clear and ensure something is shown.
- On Cocoa, invalid text in DBCS encodings will be interpreted through the single-byte MacRoman encoding as that will accept any byte.
- Diff lexer adds styles for diffs containing patches.
- Crashes fixed on macOS for invalid DBCS characters when dragging text, changing case of text, case-insensitive searching, and retrieving text as UTF-8.
- Regular expression crash fixed on macOS when linking to libstdc++.
- SciTE on GTK+, when running in single-instance mode, now forwards all command line arguments to the already running instance. This allows "SciTE filename -goto:line" to work.

### Release 4.0.5

- Released 10 May 2018.
- Add experimental SC_DOCUMENTOPTION_TEXT_LARGE option to accommodate documents larger than 2 GigaBytes.
- Additional print option SC_PRINT_SCREENCOLOURS prints with the same colours used on screen including line numbers.
- SciTE can read settings in EditorConfig format when enabled with editor.config.enable property.
- EDIFACT lexer adds property lexer.edifact.highlight.un.all to highlight all UN* segments. Feature #1166.
- Fortran folder understands "change team" and "endteam". Feature #1216.
- Set the last X chosen when SCI_REPLACESEL called to ensure macros work when text insertion followed by caret up or down.
- Bugs fixed in regular expression searches in Scintilla where some matches did not occur in an effort to avoid infinite loops when replacing on empty matches like "^" and "$". Applications should always handle empty matches in a way that avoids infinite loops, commonly by incrementing the search position after replacing an empty match. SciTE fixes a bug where replacing "^" always matched on the first line even when it was an "in selection" replace and the selection started after the line start.
- Bug fixed in SciTE where invalid numeric properties could crash.
- Runtime warnings fixed with SciTE on GTK after using Find in Files.
- SciTE on Windows find and replace strips place caret at end of text after search.
- Bug fixed with SciTE on macOS where corner debris appeared in the margin when scrolling. Fixed by not completely hiding the status bar so the curved corner is no longer part of the scrolling region. By default, 4 pixels of the status bar remain visible and this can be changed with the statusbar.minimum.height property or turned off if the debris are not a problem by setting the property to 0.

### Release 4.0.4

- Released 10 April 2018.
- On Win32, the standard makefiles build a libscintilla static library as well as the existing dynamic libraries. The statically linked version of SciTE, Sc1, links to this static library. A new file, ScintillaDLL.cxx, provides the DllMain function required for a stand-alone Scintilla DLL. Build and project files should include this file when producing a DLL and omit it when producing a static library or linking Scintilla statically. The STATIC_BUILD preprocessor symbol is no longer used.
- On Win32, Direct2D support is no longer automatically detected during build. DISABLE_D2D may still be defined to remove Direct2D features.
- In some cases, invalid UTF-8 is handled in a way that is a little friendlier. For example, when copying to the clipboard on Windows, an invalid lead byte will be copied as the equivalent ISO 8859-1 character and will not hide the following byte. Feature #1211.
- Lexer added for the Maxima computer algebra language. Feature #1210.
- Fix hang in Lua lexer when lexing a label up to the terminating "::". Bug #1999.
- Lua lexer matches identifier chains with dots and colons. Bug #1952.
- For rectangular selections, pressing Home or End now moves the caret to the Home or End position instead of the limit of the rectangular selection.
- Fix move-extends-selection mode for rectangular and line selections.
- On GTK+, change lifetime of selection widget to avoid runtime warnings.
- Fix building on Mingw/MSYS to perform file copies and deletions. Bug #1993.
- SciTE can match a wider variety of file patterns where '*' is in the middle of the pattern and where there are multiple '*'. A '?' matches any single character.
- SciTE on Windows can execute Python scripts directly by name when on path. Feature #1209.
- SciTE on Windows Find in Files checks for cancel after every 10,000 lines read so can be stopped on huge files.
- SciTE remembers entered values in lists in more cases for find, replace and find in files. Bug #1715.

### Release 4.0.3

- Released 12 February 2018.
- Features from C++14 and C++17 are used more often, with build files now specifying c++17, gnu++17, c++1z, or std:c++latest (MSVC). Requires Microsoft Visual C++ 2017.5, GCC 7, Xcode 9.2 or Clang 4.0 or newer.
- SCI_CREATEDOCUMENT adds a bytes argument to allocate memory for an initial size. SCI_CREATELOADER and SCI_CREATEDOCUMENT add a documentOption argument to allow choosing different document capabilities.
- Add SC_DOCUMENTOPTION_STYLES_NONE option to stop allocating memory for styles.
- Add SCI_GETMOVEEXTENDSSELECTION to allow applications to add more complex selection commands.
- SciTE property bookmark.symbol allows choosing symbol used for bookmarks. Feature #1208.
- Improve VHDL lexer's handling of character literals and escape characters in strings.

### Release 4.0.1

- Released 23 October 2017.
- The ILoader interface is defined in its own header ILoader.h as it is not related to lexing so doesn't belong in ILexer.h.
- The Scintilla namespace is always active for internal symbols and for the lexer interfaces ILexer4 and IDocument.
- The Baan lexer checks that matches to 3rd set of keywords are function calls and leaves as identifiers if not. Baan lexer and folder support #context_on / #context_off preprocessor feature.
- The C++ lexer improved preprocessor conformance.
  Default value of 0 for undefined preprocessor symbols.
  #define A is treated as #define A 1.
  "defined A" removes "A" before replacing "defined" with value. Bug #1966.

### Release 4.0.0

- Released 16 August 2017.
- This is an unstable release with changes to interfaces used for lexers and platform access. Some more changes may occur to internal and external interfaces before stability is regained with 4.1.0.
- Uses C++14 features. Requires Microsoft Visual C++ 2017, GCC 7, and Clang 4.0 or newer.
- Support dropped for GTK+ versions before 2.24.
- The lexer interfaces ILexer and ILexerWithSubStyles, along with additional style metadata methods, were merged into ILexer4. Most lexers will need to be updated to match the new interfaces.
- The IDocumentWithLineEnd interface was merged into IDocument.
- The platform layer interface has changed with unused methods removed, a new mechanism for reporting events, removal of methods that take individual keyboard modifiers, and removal of old timer methods.
- Style metadata may be retrieved from lexers that support this through the SCI_GETNAMEDSTYLES, SCI_NAMEOFSTYLE, SCI_TAGSOFSTYLE, and SCI_DESCRIPTIONOFSTYLE APIs.
- The Cocoa platform layer uses Automatic Reference Counting (ARC).
- The default encoding in Scintilla is UTF-8.
- An SCN_AUTOCSELECTIONCHANGE notification is sent when items are highlighted in an autocompletion or user list.
- The data parameter to ILoader::AddData made const. Bug #1955.

- SciTE allows event handlers to be arbitrary callables, not just functions. Feature #1190.
- SciTE allows user.shortcuts to be defined with symbolic Scintilla messages like 'Ctrl+L|SCI_LINEDELETE|'.
- The Matlab lexer treats 'end' as a number rather than a keyword when used as an index. This also stops incorrect folding. Bug #1951.
- The Matlab folder implements "fold", "fold.comment", and "fold.compact" properties. Bug #1965.
- The Rust lexer recognizes 'usize' numeric literal suffixes. Bug #1919.
- Ensure redraw when application changes overtype mode so caret change visible even when not blinking. Notify application with SC_UPDATE_SELECTION when overtype changed - previously sent SC_UPDATE_CONTENT.
- Fix drawing failure when in wrap mode for delete to start/end of line which affects later lines but did not redraw them. Also fixed drawing for wrap mode on GTK+ 2.x. Bug #1949.
- On GTK+ fix drawing problems including incorrect scrollbar redrawing and flickering of text. Bug #1876.
- On Linux, both for GTK+ and Qt, the default modifier key for rectangular selection is now Alt. This is the same as Windows and macOS. This was changed from Ctrl as window managers are less likely to intercept Alt+Drag for moving windows than in the past.
- On Cocoa, fix doCommandBySelector but avoid double effect of 'delete' key. Bug #1958.
- On Qt, the updateUi signal includes the 'updated' flags. No updateUi signal is sent for focus in events. These changes make Qt behave more like the other platforms.
- On Qt, dropping files on Scintilla now fires the SCN_URIDROPPED notification instead of inserting text.
- On Qt, focus changes send the focusChanged signal. Bug #1957.
- On Qt, mouse tracking is reenabled when the window is reshown. Bug #1948.
- On Windows, the DirectWrite modes SC_TECHNOLOGY_DIRECTWRITEDC and SC_TECHNOLOGY_DIRECTWRITERETAIN are no longer provisional.

### Release 3.7.1

- Released 4 December 2016.
- The Scintilla namespace is no longer applied to struct definitions in Scintilla.h even when SCI_NAMESPACE defined. Client code should not define SCI_NAMESPACE.
- Structure names in Scintilla.h without prefixes are deprecated and will now only be usable with INCLUDE_DEPRECATED_FEATURES defined.
  Use the newer names with the "Sci_" prefix:
  CharacterRange → Sci_CharacterRange
  TextRange → Sci_TextRange
  TextToFind → Sci_TextToFind
  RangeToFormat → Sci_RangeToFormat
  NotifyHeader → Sci_NotifyHeader

- Word selection, navigation, and manipulation is now performed on characters instead of bytes leading to more natural behaviour for multi-byte encodings like UTF-8. For UTF-8 characters 0x80 and above, classification into word; punctuation; space; or line-end is based on the Unicode general category of the character and is not customizable. Bug #1832.
- Two enums changed in Scintilla.iface which may lead to changed bindings. There were 2 FontQuality enums and the first is now PhasesDraw. The prefix for FoldAction was SC_FOLDACTION and is now SC_FOLDACTION_ which is similar to other enums. These changes do not affect the standard C/C++ binding.
- EDGE_MULTILINE and SCI_MULTIEDGEADDLINE added to allow displaying multiple vertical edges simultaneously.

- C++11 range-based for loops used in SciTE so GCC 4.6 is now the minimum supported version.
- SC_CHARSET_DEFAULT now means code page 1252 on Windows unless a code page is set. This prevents unexpected behaviour and crashes on East Asian systems where default locales are commonly DBCS. Projects which want to default to DBCS code pages in East Asian locales should set the code page and character set explicitly.
- SCVS_NOWRAPLINESTART option stops left arrow from wrapping to the previous line. Most commonly wanted when virtual space is used. Bug #1648.

### Release 3.6.5

- Released 26 April 2016.
- JSON lexer added. Feature #1140.
- The C++ lexer fixes a bug with multi-line strings with line continuation where the string style overflowed after an edit. Bug #1824.

- The Scintilla framework on Cocoa now contains version numbers.
- SciTE's standard properties collect values from all active .properties file to produce the Language menu and the file types pull-down in the File open dialog.
- The single executable version of SciTE, Sc1, uses 'module' statements within its embedded properties. This makes it act more like the full distribution allowing languages to be turned on and off by setting imports.include and imports.exclude. The default imports.exclude property adds eiffel, erlang, ps, and pov so these languages are turned off by default.
- SciTE adds an output.blank.margin.left property to allow setting the output pane margin to a different width than the edit pane.
- CoffeeScript lexer highlights ranges correctly. Bug #1765.
- Markdown lexer treats line starts consistently to always highlight *foo* or similar at line start. Bug #1766.
- Optimize marker redrawing by only drawing affected lines when markers shown in the text.
- On Cocoa, timers and idling now work in modal dialogs. This also stops some crashes.
- On Cocoa, fix crashes when deleting a ScintillaView. These crashes could occur when scrolling at the time the ScintillaView was deleted although there may have been other cases.

- The errorlist lexer understands some ANSI escape sequences to change foreground colour and intensity. This is sufficient to colour diagnostic output from gcc and clang when -fdiagnostics-color set.
- The errorlist lexer allows the line number to be 0 in GCC errors as some tools report whole file errors as line 0.
- MySql lexer fixes empty comments /**/ so the comment state does not continue.
- VHDL folder supports "protected" keyword.
- Treat CRLF line end as two characters in SCI_COUNTCHARACTERS. Bug #1757.

- On GTK+ the keyboard command for View | End of Line was changed to Ctrl+Shift+N to avoid clash with Search | Selection Add Next. Bug #1750.

### Release 3.6.0

- Released 3 August 2015.
- External interfaces use the Sci_Position and Sci_PositionU typedefs instead of int and unsigned int to allow for changes to a 64-bit interface on 64-bit platforms in the future. Applications and external lexers should start using the new type names so that they will be compatible when the 64-bit change occurs. There is also Sci_PositionCR (long) for use in the Sci_CharacterRange struct which will also eventually become 64-bit.
- Multiple selection now works over more key commands. The new multiple-selection handling commands include horizontal movement and selection commands, line up and down movement and selection commands, word and line deletion commands, and line end insertion. This change in behaviours is conditional on setting the SCI_SETADDITIONALSELECTIONTYPING property.
- Autocompletion lists send an SCN_AUTOCCOMPLETED notification after the text has been inserted. Feature #1109.

- On Cocoa fix problems with positioning of autocompletion lists near screen edge or under dock. Cancel autocompletion when window moved. Bug #1740.
- Fix drawing problem when control characters are in a hidden style as they then have a zero width rectangle to draw but modify that rectangle in a way that clears some pixels.
- Report error when attempt to resize buffer to more than 2GB with SC_STATUS_FAILURE.
- Fix bug on GTK+ with scroll bars leaking. Bug #1742.
- LexOthers.cxx file split into one file per lexer: LexBatch, LexDiff, LexErrorList, LexMake, LexNull, and LexProps.
- SciTE exporters handle styles > 127 correctly now.
- SciTE on Windows can scale window element sizes based on the system DPI setting.
- SciTE implements find.in.files.close.on.find on all platforms, not just Windows.

### Release 3.5.7

- Released 20 June 2015.
- Added SCI_MULTIPLESELECTADDNEXT to add the next occurrence of the main selection within the target to the set of selections as main. If the current selection is empty then select word around caret. SCI_MULTIPLESELECTADDEACH adds each occurrence of the main selection within the target to the set of selections.
- SciTE adds "Selection Add Next" and "Selection Add Each" commands to the Search menu.

### Release 3.5.4

- Released 8 March 2015.
- Indicators may have a different colour and style when the mouse is over them or the caret is moved into them.
- An indicator may display in a large variety of colours with the SC_INDICFLAG_VALUEFORE flag taking the colour from the indicator's value, which may differ for every character, instead of its foreground colour attribute.
- On Cocoa, additional IME methods implemented so that more commands are enabled. For Japanese: Reverse Conversion, Convert to Related Character, and Search Similar Kanji can now be performed. The global definition hotkey Command+Control+D and the equivalent three finger tap gesture can be used.
- Minimum version of Qt supported is now 4.8 due to the use of QElapsedTimer::nsecsElapsed.
- On Windows, for Korean, the VK_HANJA key is implemented to choose Hanja for Hangul and to convert from Hanja to Hangul.

- VHDL folder fixes hang in folding when document starts with "entity".
- Add new indicators INDIC_COMPOSITIONTHIN, INDIC_FULLBOX, and INDIC_TEXTFORE. INDIC_COMPOSITIONTHIN is a thin underline that mimics the appearance of non-target segments in OS X IME. INDIC_FULLBOX is similar to INDIC_STRAIGHTBOX but covers the entire character area which means that indicators with this style on contiguous lines may touch. INDIC_TEXTFORE changes the text foreground colour.
- Fix adaptive scrolling speed for GTK+ on OS X with GTK Quartz backend (as opposed to X11 backend). Bug #1696.
- Fix position of autocompletion and calltips on Cocoa when there were two screens stacked vertically.
- Fix crash in SciTE when saving large files in background when closing application. Bug #1691.

- Shell lexer fixes three issues with here-documents. Bug #1672.
- Verilog lexer highlights doc comment keywords; has separate styles for input, output, and inout ports (lexer.verilog.portstyling); fixes a bug in highlighting numbers; can treat upper-case identifiers as keywords (lexer.verilog.allupperkeywords); and can use different styles for code that is inactive due to preprocessor commands (lexer.verilog.track.preprocessor, lexer.verilog.update.preprocessor).
- When the calltip window is taller than the Scintilla window, leave it in a position that avoids overlapping the Scintilla text.
- When a text margin is displayed, for annotation lines, use the background colour of the base line.
- On Windows GDI, assume font names are encoded in UTF-8. This matches the Direct2D code path.
- Fix paste for GTK+ on OS X. Bug #1677.
- Reverted a fix on Qt where Qt 5.3 has returned to the behaviour of 4.x. Bug #1575.
- When the mouse is on the line between margin and text changed to treat as within text. This makes the PLAT_CURSES character cell platform work better.

- Include support for using C++11 <regex> for regular expression searches. Enabling this requires rebuilding Scintilla with a non-default option. This is a provisional feature and may change API before being made permanent.
- Allocate indicators used for Input Method Editors after 31 which was the previous limit of indicators to ensure no clash between the use of indicators for IME and for the application.
- ANNOTATION_INDENTED added which is similar to ANNOTATION_BOXED in terms of positioning but does not show a border. Feature #1086.
- Allow platform overrides for drawing tab arrows, wrap markers, and line markers. Size of double click detection area is a variable. These enable better visuals and behaviour for PLAT_CURSES as it is character cell based.

- Text may share space vertically so that extreme ascenders and descenders are not cut off by calling SCI_SETPHASESDRAW(SC_PHASES_MULTIPLE).
- Separate timers are used for each type of periodic activity and they are turned on and off as required. This saves power as there are fewer wake ups. On recent releases of OS X Cocoa and Windows, coalescing timers are used to further save power. Bug #1086. Bug #1532.
- Explicit tab stops may be set for each line.
- On Windows and GTK+, when using Korean input methods, IME composition is moved from a separate window into the Scintilla window.
- SciTE adds a "Clean" command to the "Tools" menu which is meant to be bound to a command like "make clean".

- Fix SciTE bug where toggle bookmark did not work after multiple lines with bookmarks merged. Bug #1617.

### Release 3.4.4

- Released 3 July 2014.
- Style byte indicators removed. They were deprecated in 2007. Standard indicators should be used instead. Some elements used by lexers no longer take number of bits or mask arguments so lexers may need to be updated for LexAccessor::StartAt, LexAccessor::SetFlags (removed), LexerModule::LexerModule.
- When multiple selections are active, autocompletion text may be inserted at each selection with new SCI_AUTOCSETMULTI method.
- C++ lexer fixes crash for "#define x(". Bug #1614.

- Fix bug on Cocoa where emoji were treated as being zero width.
- Fix crash on GTK+ with Ubuntu 12.04 and overlay scroll bars.
- Avoid creating a Cairo context when measuring text on GTK+ as future versions of GTK+ may prohibit calling gdk_cairo_create except inside drawing handlers. This prohibition may be required on Wayland.
- On Cocoa, the registerNotifyCallback method is now marked as deprecated so client code that uses it will display an error message. Client code should use the delegate mechanism or subclassing instead. The method will be removed in the next version.
- On Cocoa, package Scintilla more in compliance with platform conventions. Only publish public headers in the framework headers directory. Only define the Scintilla namespace in Scintilla.h when compiling as C++. Use the Cocoa NS_ENUM and NS_OPTIONS macros for exposed enumerations. Hide internal methods from public headers. These changes are aimed towards publishing Scintilla as a module which will allow it to be used from the Swift programming language, although more changes will be needed here.
- Fix crash in SciTE when stream comment performed at line end. Bug #1610.
- For SciTE on Windows, display error message when common dialogs fail. Bug #156.

### Release 2.20

- Released 30 July 2010.
- Lexers are implemented as objects so that they may retain extra state. The interfaces defined for this are tentative and may change before the next release. Compatibility classes allow current lexers compiled into Scintilla to run with few changes. The interface to external lexers has changed and existing external lexers will need to have changes made and be recompiled. A single lexer object is attached to a document whereas previously lexers were attached to views which could lead to different lexers being used for split views with confusing results.
- C++ lexer understands the preprocessor enough to grey-out inactive code due to conditional compilation.
- SciTE can use strips within the main window for find and replace rather than dialogs. On Windows SciTE always uses a strip for incremental search.

- Lexing performed incrementally when needed by wrapping to make user interface more responsive.
- SciTE setting replaceselection:yes works on GTK+.
- SciTE Lua scripts calling io.open or io.popen on Windows have arguments treated as UTF-8 and converted to Unicode so that non-ASCII file paths will work. Lua files with non-ASCII paths run. Bug #3016951.
- Crash fixed when searching for empty string. Bug #3017572.

- On Windows, auto-completion lists are visually outdented rather than indented.
- Close all command in SciTE.
- On Windows multiple files can be dragged into SciTE.
- When saving a file, the SciTE option save.deletes.first deletes it before doing the save. This allows saving with a different capitalization on Windows.
- When use tabs option is off pressing the tab key inserts spaces.
- Bug in indicators leading to extra line drawn fixed.

### Release 1.28

- Released on 27 June 2000.
- Fixes crash in indentation guides when indent size set to 0.

Global properties file location configurable at compile time defaulting to $prefix/share/scite. $prefix determined from Gnome if present else its /usr/local and can be overridden by installer. Gnome menu integration performed in make install if Gnome present.

### Release 1.27

- Released on 23 June 2000.
- Indentation guides. View whitespace mode may be set to not display whitespace in indentation.
- Set methods have corresponding gets for UndoCollection, BufferedDraw, CodePage, UsePalette, ReadOnly, CaretFore, and ModEventMask.

- Static linking supported and Tidy.EXE, a statically linked version of Tide.EXE. Changes to compiler flags in the makefiles to optimize for size.
- Scintilla supports a 'savepoint' in the undo stack which can be set by the container when the document is saved. Notifications are sent to the container when the savepoint is entered or left, allowing the container to display a dirty indicator and change its menus.
- When Scintilla is set to read-only mode, a notification is sent to the container should the user try to edit the document. This can be used to check the document out of a version control system.
- There is an API for setting the appearance of indicators.
- The keyboard mapping can be redefined or removed so it can be implemented completely by the container. All of the keyboard commands are now commands which can be sent by the container.
- A home command like Visual C++ with one hit going to the start of the text on the line and the next going to the left margin is available. I do not personally like this but my fingers have become trained to it by much repetition.
- SCI_MARKERDELETEALL has an argument in wParam which is the number of the type marker to delete with -1 performing the old action of removing all marker types.
- Tide now understands both the file name and line numbers in error messages in most cases.
