## [Unreleased]

## [2.1.0] - 2026-07-30
### Changed
  - Bump the minimum supported Python from 3.9 (EOL) to 3.10. CircleCI executors bumped from
    `circleci/python:3.9` to `cimg/python:3.10` accordingly.
  - Release to PyPI via a GitHub Actions workflow using PyPI Trusted Publishing (OIDC),
    instead of a CircleCI job using a long-lived API token. CircleCI still runs lint, unit, and
    functional tests.
  - Replace `twine` with `uv publish` for building/publishing/checking release artifacts.
  - Derive the package version from the git tag at build time via `setuptools-scm`,
    instead of a committed `version` field in `pyproject.toml`. Releases no longer
    require a version-bump commit before tagging; `scripts/verify_version.py` is
    removed since there's no longer a committed version to verify against tags.
    `tentaclio_databricks.__version__` is now exposed at runtime via `importlib.metadata`.
### Fixed
  - Missing `_prepend_comment()` method call within the `get_df()` method.
  - Make `isort` and `black` behaviour consistent for imports sorting and formatting.
### Added
  - Add `Programming Language :: Python :: 3.12`, `Programming Language :: Python :: 3.13` and
    `Programming Language :: Python :: 3.14` classifiers.
  - Add `get_pl()` method to fetch polars data frame from Databricks.
  - Make `polars` an optional dependency accordingly. If `polars` is not available raise a
    `ModuleNotFoundError`.
