[users at bb.net] Buildbot 2.10.2 and 3.0.0

[Povilas Kanapickas]

Buildbot 2.10.2 and 3.0.0 have been released!

See more details in the notes for these releases:

https://buildbot.readthedocs.io/en/v2.10.2/relnotes/index.html

https://buildbot.readthedocs.io/en/v3.0.0/relnotes/index.html

Please upgrade to 2.10.2 before upgrading to a 3.x release. 2.10.2 will
emit warnings for deprecated functionality which then can be addressed
incrementally. 3.0.0 removes a lot of deprecated functionality and using
it will result in hard configuration or runtime errors.

Regards,
Povilas
