[dependabot]

Bumps greenlet from 2.0.2 to 3.0.3.

Changelog

Sourced from greenlet's changelog.

3.0.3 (2023-12-21)

• Python 3.12: Restore the full ability to walk the stack of a suspended greenlet; previously only the innermost frame was exposed. See issue 388 <https://github.com/python-greenlet/greenlet/issues/388>. Fix by Joshua Oreman in PR 393 <https://github.com/python-greenlet/greenlet/pull/393/>.

3.0.2 (2023-12-08)

• Packaging: Add a minimal pyproject.toml to sdists.
• Packaging: Various updates to macOS wheels.
• Fix a test case on Arm32. Note that this is not a supported platform (there is no CI for it) and support is best effort; there may be other issues lurking. See issue 385 <https://github.com/python-greenlet/greenlet/issues/385>_

3.0.1 (2023-10-25)

• Fix a potential crash on Python 3.8 at interpreter shutdown time. This was a regression from earlier 3.0.x releases. Reported by Matt Wozniski in issue 376 <https://github.com/python-greenlet/greenlet/issues/376>_.

3.0.0 (2023-10-02)

• No changes from 3.0rc3 aside from the version number.

3.0.0rc3 (2023-09-12)

• Fix an intermittent error during process termination on some platforms (GCC/Linux/libstdc++).

3.0.0rc2 (2023-09-09)

• Fix some potential bugs (assertion failures and memory leaks) in previously-untested error handling code. In some cases, this means that the process will execute a controlled abort() after severe trouble when previously the process might have continued for some time with a corrupt state. It is unlikely those errors occurred in practice.
