+- New upstream release 1.6.0
+
+  ### Added
+
+  - Improve error message for invalid markers ([#569](https://github.com/python-poetry/poetry-core/pull/569)).
+  - Increase robustness when deleting temporary directories on Windows ([#460](https://github.com/python-poetry/poetry-core/pull/460)).
+  - Add support for file dependencies with subdirectories ([#467](https://github.com/python-poetry/poetry-core/pull/467)).
+
+  ### Changed
+
+  - Replace `tomlkit` with `tomli`, which changes the interface of some _internal_ classes ([#483](https://github.com/python-poetry/poetry-core/pull/483)).
+  - Deprecate `Package.category` ([#561](https://github.com/python-poetry/poetry-core/pull/561)).
+
+  ### Fixed
+
+  - Fix a performance regression in marker handling ([#568](https://github.com/python-poetry/poetry-core/pull/568)).
+  - Fix an issue where wildcard version constraints were not handled correctly ([#402](https://github.com/python-poetry/poetry-core/pull/402)).
+  - Fix an issue where `poetry build` created duplicate Python classifiers if they were specified manually ([#578](https://github.com/python-poetry/poetry-core/pull/578)).
+  - Fix an issue where local versions where not handled correctly ([#579](https://github.com/python-poetry/poetry-core/pull/579)).
+
+  ### Vendoring
+
+  - [`attrs==23.1.0`](https://github.com/python-attrs/attrs/blob/main/CHANGELOG.md)
+  - [`packaging==23.1`](https://github.com/pypa/packaging/blob/main/CHANGELOG.rst)
+  - [`tomli==2.0.1`](https://github.com/hukkin/tomli/blob/master/CHANGELOG.md)
+  - [`typing-extensions==4.5.0`](https://github.com/python/typing_extensions/blob/main/CHANGELOG.md)
+
