+### Fixed

+- Fixed an error which caused the configuration environment variables (like `POETRY_HTTP_BASIC_XXX_PASSWORD`) to not be used ([#1909](https://github.com/python-poetry/poetry/pull/1909)).
+- Fixed an error where the `--help` option was not working ([#1910](https://github.com/python-poetry/poetry/pull/1910)).
+- Fixed an error where packages from private indices were not decompressed properly ([#1851](https://github.com/python-poetry/poetry/pull/1851)).
+- Fixed an error where the version of some PEP-508-formatted wheel dependencies was not properly retrieved ([#1932](https://github.com/python-poetry/poetry/pull/1932)).
+- Fixed internal regexps to avoid potential catastrophic backtracking errors ([#1913](https://github.com/python-poetry/poetry/pull/1913)).
+- Fixed performance issues when custom indices were defined in the `pyproject.toml` file ([#1892](https://github.com/python-poetry/poetry/pull/1892)).
+- Fixed the `get_requires_for_build_wheel()` function of `masonry.api` which wasn't returning the proper result ([#1875](https://github.com/python-poetry/poetry/pull/1875)).
