cleo (^2.0.0)

• Fix an issue where shell completions had syntax errors (#247).

@Secrus PTAL if we want to mention cleo.

[dimbleby]

python-poetry/poetry-core#487 maybe worth a mention in the poetry-core changes

IMO the cleo upgrade isn't in itself interesting, but the poetry bugs that it fixes are. These are the ones that I know about

• poetry.bash-completion has multiple syntax errors #4572
• poetry displays very verbose "broken pipe traceback" if output is not fully read #3602
• Errors not shown following clean-up of big stacks #5846

@Secrus PTAL if we want to mention cleo.

I agree with Dimbleby, no need to include changelog for cleo, maybe just link to cleo changelog: https://github.com/python-poetry/cleo/blob/main/CHANGELOG.md#100---2022-11-21

Updated as per maintainer's call, I'm pushing a revised changelog and then we're cutting the release.

[yermukov]

This is update broke the whole image built and we had to go nuts to find out what actually broke it.

If you have discovered a showstopper regression in the release, please open a new issue with a detailed description, examples of what is going wrong, and a tested, minimal reproducer. Thank you.
