Hello PyPyistas,
we have renamed the pypy3 package to pypy3.7 (both the component and the
"binary" package) on Fedora 35+. The package no longer installs to
/usr/lib64/pypy3-7.x/ but rather to /usr/lib64/pypy3.7/.
*What is this good for?*
When PyPy 3 was updated from Python 3.N to 3.N+1, traditionally we have only
updated it in Rawhide (and Branched), not to do a backward-incompatible update
in stable Fedoras.
With this renaming, you can now¹ install pypy3.7 on all Fedoras, despite pypy3
being 3.6 on Fedora 33 and 34.
¹ (The builds are still running, expect an update in Bodhi later today.)
Once PyPy 3.8 is released, we can introduce it to all Fedora versions.
*Warning to Rawhide/Fedora 35 users*
If you already used the pypy3 package with PyPy 3.7, the pypy3.7 package will
obsolete it. However, the installation paths are different, so you will need to
re-create your PyPy 3 virtual environments.
*Details* (feel free to ignore the rest of this email)
During a lifetime of one stable Fedora release, you will get:
- pypy3.N that provides pypy3 and has /usr/bin/pypy3
- pypy3.N+c introduced later in the lifetime
E.g. for Fedora 35:
- pypy3.7 that provides pypy3 and has /usr/bin/pypy3
- pypy3.8 (or newer) might be introduced in the future
For Fedora 33 and 34, there is a transition period:
- pypy3 provides pypy3.6 and has /usr/bin/pypy3
- pypy3.7 was just introduced
- pypy3.8 (or newer) might be introduced in the future
See for example on Fedora 33:
$ rpm -qa | grep pypy3

Note that we *do not* plan to maintain old PyPy versions indefinitely, we plan
to retire them from Rawhide/Branched as soon as new versions arrive and only
keep them alive until stable Fedoras goes EOL.
