 # Change Log
 
+
+## [1.3.0] - 2022-12-09
+
+### Added
+
+- Mark the lock file with an `@generated` comment as used by common tooling ([#2773](https://github.com/python-poetry/poetry/pull/2773)).
+- `poetry check` validates trove classifiers and warns for deprecations ([#2881](https://github.com/python-poetry/poetry/pull/2881)).
+- Introduce a top level `-C, --directory` option to set the working path ([#6810](https://github.com/python-poetry/poetry/pull/6810)).
+
+### Changed
+- **New lock file format (version 2.0)** ([#6393](https://github.com/python-poetry/poetry/pull/6393)).
+- Path dependency metadata is unconditionally re-locked ([#6843](https://github.com/python-poetry/poetry/pull/6843)).
+- URL dependency hashes are locked ([#7121](https://github.com/python-poetry/poetry/pull/7121)).
+- `poetry update` and `poetry lock` should now resolve dependencies more similarly ([#6477](https://github.com/python-poetry/poetry/pull/6477)).
+- `poetry publish` will report more useful errors when a file does not exist ([#4417](https://github.com/python-poetry/poetry/pull/4417)).
+- `poetry add` will check for duplicate entries using canonical names ([#6832](https://github.com/python-poetry/poetry/pull/6832)).
+- Wheels are preferred to source distributions when gathering metadata ([#6547](https://github.com/python-poetry/poetry/pull/6547)).
+- Git dependencies of extras are only fetched if the extra is requested ([#6615](https://github.com/python-poetry/poetry/pull/6615)).
+- Invoke `pip` with `--no-input` to prevent hanging without feedback ([#6724](https://github.com/python-poetry/poetry/pull/6724), [#6966](https://github.com/python-poetry/poetry/pull/6966)).
+- Invoke `pip` with `--isolated` to prevent the influence of user configuration ([#6531](https://github.com/python-poetry/poetry/pull/6531)).
+- Interrogate environments with Python in isolated (`-I`) mode ([#6628](https://github.com/python-poetry/poetry/pull/6628)).
+- Raise an informative error when multiple version constraints overlap and are incompatible ([#7098](https://github.com/python-poetry/poetry/pull/7098)).
+

+- Fix an issue where git dependencies were fetched unnecessarily when running `poetry lock --no-update` ([#6131](https://github.com/python-poetry/poetry/pull/6131)).
+- Fix an issue where stdout was polluted with messages that should go to stderr ([#6429](https://github.com/python-poetry/poetry/pull/6429)).
+- Fix an issue with `poetry shell` activation and zsh ([#5795](https://github.com/python-poetry/poetry/pull/5795)).

+- Fix an issue where `experimental.system-git-client` could not be used via environment variable ([#6783](https://github.com/python-poetry/poetry/pull/6783)).
+- Fix an issue where Poetry fails with an `AssertionError` due to `distribution.files` being `None` ([#6788](https://github.com/python-poetry/poetry/pull/6788)).
+- Fix an issue where `poetry env info` did not respect `virtualenvs.prefer-active-python` ([#6986](https://github.com/python-poetry/poetry/pull/6986)).
+- Fix an issue where `poetry env list` does not list the in-project environment ([#6979](https://github.com/python-poetry/poetry/pull/6979)).
+- Fix an issue where `poetry env remove` removed the wrong environment ([#6195](https://github.com/python-poetry/poetry/pull/6195)).
+- Fix an issue where the return code of a script was not relayed as exit code ([#6824](https://github.com/python-poetry/poetry/pull/6824)).

+- `ParseConstraintError` is now raised on version and constraint parsing errors, and includes information on the package that caused the error ([#514](https://github.com/python-poetry/poetry-core/pull/514)).
+- Fix an issue where invalid PEP 508 requirements were generated due to a missing space before semicolons ([#510](https://github.com/python-poetry/poetry-core/pull/510)).
+- Fix an issue where relative paths were encoded into package requirements, instead of a file:// URL as required by PEP 508 ([#512](https://github.com/python-poetry/poetry-core/pull/512)).
+
+### poetry-plugin-export ([`^1.2.0`](https://github.com/python-poetry/poetry-plugin-export/releases/tag/1.2.0))
