### Release Notes

<summary>pytest-dev/iniconfig (iniconfig)</summary>

### [`v2.3.0`](https://redirect.github.com/pytest-dev/iniconfig/blob/HEAD/CHANGELOG#230)

[Compare Source](https://redirect.github.com/pytest-dev/iniconfig/compare/v2.2.0...v2.3.0)

\=====

-   add IniConfig.parse() classmethod with strip_inline_comments parameter (fixes [#&#8203;55](https://redirect.github.com/pytest-dev/iniconfig/issues/55))
    -   by default (strip_inline_comments=True), inline comments are properly stripped from values
    -   set strip_inline_comments=False to preserve old behavior if needed
-   IniConfig() constructor maintains backward compatibility (does not strip inline comments)
-   users should migrate to IniConfig.parse() for correct comment handling
-   add strip_section_whitespace parameter to IniConfig.parse() (regarding [#&#8203;4](https://redirect.github.com/pytest-dev/iniconfig/issues/4))
    -   opt-in parameter to strip Unicode whitespace from section names
    -   when True, strips Unicode whitespace (U+00A0, U+2000, U+3000, etc.) from section names
    -   when False (default), preserves existing behavior for backward compatibility
-   clarify Unicode whitespace handling (regarding [#&#8203;4](https://redirect.github.com/pytest-dev/iniconfig/issues/4))
    -   since iniconfig 2.0.0 (Python 3 only), all strings are Unicode by default
    -   Python 3's str.strip() has handled Unicode whitespace since Python 3.0 (2008)
    -   iniconfig automatically benefits from this in all supported versions (Python >= 3.10)
    -   key names and values have Unicode whitespace properly stripped using Python's built-in methods

### [`v2.2.0`](https://redirect.github.com/pytest-dev/iniconfig/blob/HEAD/CHANGELOG#220)

[Compare Source](https://redirect.github.com/pytest-dev/iniconfig/compare/v2.1.0...v2.2.0)

\=====

-   drop Python 3.8 and 3.9 support (now requires Python >= 3.10)
