Sage 9.7.rc2 released

[Volker Braun]

As always, you can get the latest beta version from the "develop" git branch. Alternatively, the self-contained source tarball is at http://www.sagemath.org/download-latest.html

This should be the last rc...

4f225f4cc66 (origin/develop) Trac #34533: OS X 12.6 "chained fixups" warning

[John H Palmieri]

Al tests pass for me on OS X Intel.

This is on Apple Silicon Macs with Homebrew up to date (make and make pytest and  make ptestlong).

On macOS 12.6 (Monterey) with Xcode 14.0:  no problems.

On macOS 11.7 (Big Sur) with Xcode 13.2.1:  make ptestlong gives

The first one succeeds when run alone, as usual.

The third one is known (see https://trac.sagemath.org/ticket/33212).

The second one appears almost all the time (and always when run alone), but I have been unable to find a pattern of failure:

This is fixed in #34467,

https://trac.sagemath.org/ticket/34467, 

which is critical.

[Kenji Iohara]

On my MacBook Pro with Intel Core i5, homebrew OS 12.6 and Xcode 14, it compiled from the first build and all passed !

Just to say that merging ticket

https://trac.sagemath.org/ticket/34467

as indicated by Kwankyu (thanks!), this succeeds, and no new problems arise.

On most of my machines, ptestlong passes (except for the usual transient
failures in src/sage/interfaces/process.pyx ).

However, on one machine, where there has not been any problem with 9.7.rc1, I
consistently get the doctest failure below. It seems to depend on the random
seed; with another seed (270396188935382102109749143081031101710), the doctest
passes.
