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

Hi,

"git fetch trac develop" still gives me rc1.

Ciao,

Built from a fresh clone of the developer branch, on macOS 10.11.6 (Quad-core Core i7), w/o problems.

Testing (‘ptestlong’) yielded no failures!

8.1.rc2 :

builds and passes ptestlong without any error on two different Debian machines.
does *NOT* build on Cygwin running Windows 10 + "Fall Creators Update" : psutil does not build. This is fixed in Trac#24121, which has positive review but was not included in 8.0.rc2

blocker : we need to support skylake.
the patch would be trivial, but how do I test it? Do we have a skylake patchbot?

I'm still waiting for Mac app to build and test it, but otherwise things seem fine.

One more data point :

On Cygwin running on Windows 10, after pulling Trac#24121 on top of 8.1rc2, Sage builds and passes ptestlong with three failures :

----------------------------------------------------------------------

sage -t --long --warn-long 125.6 src/sage/matrix/matrix_mod2_dense.pyx # 1 doctest failed

sage -t --long --warn-long 125.6 src/sage/parallel/map_reduce.py # 1 doctest failed

sage -t --long --warn-long 125.6 src/sage/graphs/graph_generators.py # Timed out

----------------------------------------------------------------------

The first of these failures is permanent (i. e. repetitiion of the test gives the same result) ; the other two are transient.

The failure is :

$ sage -t --long --warn-long 125.6 src/sage/matrix/matrix_mod2_dense.pyx

For me, the compilation failed (in a docker environment we are running on cocalc). Has anyone seen this sympy-error before?

yes, this is a missing dependency of docbuilding on sympy.
just restart the build...
this is one of the current blocker tickets.

There is a new test failure on Cython (I think only with ptestlong)
that I somehow did not catch before:
