Sage 10.7 released

[Volker Braun]

The "master" git branch has been updated to Sage-10.7. 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

85c8f1e8a26 (tag: 10.7, github/develop) Updated SageMath version to 10.7
858268b4001 (tag: 10.7.rc2) Updated SageMath version to 10.7.rc2

Here is a peculiar thing.  The configure script generates (and ignores) an error saying that SAGE_SPKG_CONFIGURE_ROMAN_NUMERALS_PY is not defined.

That variable appears in real_configure, on a line by itself, surrounded by a huge number of blank lines.

this is probably due to typos in spkg-configure.m4 of this spkg, which is to be fixed by
<https://github.com/sagemath/sage/commit/41b258cb138968cdc0247c378771d04a59c65b2c>
in <https://github.com/sagemath/sage/pull/40555>

My build from the github source (after make distclean, ./bootstrap,
./configure, make) fails on building package contourpy-1.3.1.

I have attached the relevant logs.

Hi John,
the spkgs involved (pybind11 and contourpy) have not been touched
since Sage 10.6.
The problem is that an old version of pybind11 is found on your system:

[contourpy-1.3.1] [spkg-install] Run-time dependency pybind11
found: YES 2.11.1

and it's too old. build/pkgs/pybind11/spkg-configure.m4 should get a
version constraint to prevent that,
although it's not clear whether you have build Sage's pybind11 which
would be OK to use, or not.
(contourpy should have thrown an error, and probably a new version
would have given a better error message)

Anyway, uninstalling the old pybind11 should fix this.

Dima




They can be upgraded, this might help.
The latest version of contourpy is 1.3.3, while spkg still has

Thanks, I will try that.
