Re: ANNOUNCE: Beam 2.24.0 will be the last release with Python 2.7 and Python 3.5 support.

[Valentyn Tymofieiev <va...@google.com>]

I am currently making changes to several jenkins suites, and I am testing
these changes by running a seed job on my in-progress PRs. This could cause
temporary unrelated test suite failures on your PRs due to different job
definitions. I will re-run the seed job in a clean state once finished, to
minimize the impact. Seed job also runs regularly.

Sorry about these possible interruptions.
