Last updated: 2018-03-14
Tracker bug: <will be assigned by the Wrangler>

Detailed Description

Python 3.7 adds numerous features and optimizations. See the upstream notes at Features for 3.7 and What's new in 3.7.

Benefit to Fedora

Fedora aims to showcase the latest in free and open source software - we should have the most recent release of Python 3. Packages in Fedora can use the new features from 3.7.

Scope

Proposal owners:
1. Retire python37 from F29+
2. Update python3 to what was in python37
  - Mass rebuild all the packages that BR python3/python3-devel/... (~2300 listed in Python 3 Porting Database for Fedora)
3. Reintroduce python36 from Fedora 25. Update it to have all fixes and enhancements from python3 in Fedora 28 (or 29 before this change)

Other developers: Maintainers of packages that fail to rebuild during the mass rebuild will be asked, using bugzilla, to fix or remove their packages from the distribution. If any issues appear, they should be solvable either by communicating with upstreams first and/or applying downstream patches. Also the package maintainers should have a look at: Porting to Python 3.7. And python-maint team will be available to help with fixing issues.

Release engineering: #Releng issue number TODO A targeted rebuild for all python packages will be required, before the mass rebuild.
