Thanks a lot @meckhardt - Merging it within the next hour.

[e42sh]

@heitorlessa got feedback from Sonatype. They verified that the current license is proprietary and mentioned the metadata presented in PKG-INFO, when downloading https://files.pythonhosted.org/packages/1a/a0/e31457a2b66aa09fce91353141fcbde53cf1084328ec1c088aab215e76bd/aws_lambda_powertools-2.7.0.tar.gz.

See https://pypi.org/project/aws-lambda-powertools/

I provided a fix, but better poetry / poetry-core must be fixed to generate the correct license metadata in PKG-INFO.

[heitorlessa]

Thanks for the heads up! Forgot for a second that Poetry generated that - I'll revert right after lunch

Merged the last one. For attribution in the release notes, is it correct to assume you work for Sonatype @meckhardt?

Thank you again!!!

[heitorlessa]

Released 2.7.1 - could you check one more time @meckhardt please?

Thanks!

@heitorlessa ❤️

License check from Nexus IQ runs through. Many thanks!

For attribution in the release notes, is it correct to assume you work for Sonatype @meckhardt?

No, I'm freelancing and one of my customers uses Nexus IQ (Sonatype product). They scan packages for license issues and vulnurabilities and, well, there was a finding :-)

@meckhardt we really appreciate raising this issue and your patience while we triple checked everything was kosher. We appreciate your support and your contribution!
