+0.19.0 (2023-07-29)
++++++++++++++++++++
+
+- Python 3.11 support
+- Massive improvements in performance for ``Interpreter`` (e.g. IPython) users.
+  This especially affects ``pandas`` users with large datasets.
+- Add ``jedi.settings.allow_unsafe_interpreter_executions`` to make it easier

+
+- Added dataclass-equivalent for attrs.define
+- Find fixtures from Pytest entrypoints; Examples of pytest plugins installed
+  like this are pytest-django, pytest-sugar and Faker.
+- Fixed Project.search, when a venv was involved, which is why for example
+  `:Pyimport django.db` did not work in some cases in jedi-vim.
