 # Change Log
 
+## [1.2.2] - 2022-10-07
+
+### Added
+- Add forward compatibility for lock file format 2.0, which will be used by Poetry 1.3 ([#6608](https://github.com/python-poetry/poetry/pull/6608)).
+
+### Changed
+- Bump `poetry-core` to [`1.3.1`](https://github.com/python-poetry/poetry-core/releases/tag/1.3.1).
+- Bump `poetry-plugin-export` to [`^1.1.1`](https://github.com/python-poetry/poetry-plugin-export/releases/tag/1.1.1).
+
+### Fixed
+
+- Fix an issue where the deprecated JSON API was used to query PyPI for available versions of a package ([#6081](https://github.com/python-poetry/poetry/pull/6081)).
+- Fix an issue where versions were escaped wrongly when building the wheel name ([#6476](https://github.com/python-poetry/poetry/pull/6476)).
+- Fix an issue where the installation of dependencies failed if pip is a dependency and is updated in parallel to other dependencies ([#6582](https://github.com/python-poetry/poetry/pull/6582)).
+- Fix an issue where the names of extras were not normalized according to PEP 685 ([#6541](https://github.com/python-poetry/poetry/pull/6541)).
+- Fix an issue where sdist names were not normalized ([#6621](https://github.com/python-poetry/poetry/pull/6621)).
+- Fix an issue where invalid constraints, which are ignored, were only reported in a debug message instead of a warning ([#6730](https://github.com/python-poetry/poetry/pull/6730)).
+
+### Docs
+
+- Rework the README and contribution docs ([#6552](https://github.com/python-poetry/poetry/pull/6552)).
+- Fix for inconsistent docs for multiple-constraint dependencies ([#6604](https://github.com/python-poetry/poetry/pull/6604)).
+- Rephrase plugin configuration ([#6557](https://github.com/python-poetry/poetry/pull/6557)).
+- Add a note about publishable repositories to `publish` ([#6641](https://github.com/python-poetry/poetry/pull/6641)).
+- Fix the path for lazy-loaded bash completion ([#6656](https://github.com/python-poetry/poetry/pull/6656)).
+- Fix a reference to the invalid option `--require` ([#6672](https://github.com/python-poetry/poetry/pull/6672)).
