Lambdex 0.1.7 is released with Python 3.10 & 3.11 support: + https://pypi.org/project/lambdex/0.1.7/ + https://github.com/pantsbuild/lambdex/blob/main/CHANGES.md#017 Although Lambdex has served folks well, this will likely be the last release since you can now use plain old PEX files (named with a

.zip

extension) directly by pre-pending handler module names with the

__pex__.

magic import prefix since Pex 2.1.98 released ~3 months ago. Pants will transition to using plain old PEXes or else hand-crafting zips in exactly the format suggested by AWS Lambda / GCF.
