I have uploaded SymPy 0.7.6 release candidate 1. Please download it
and test it. You can find it at
https://github.com/sympy/sympy/releases/tag/sympy-0.7.6.rc1.

If there are no major issues, I will aim to do the final release in one week.

The release notes for this release are at
https://github.com/sympy/sympy/wiki/release-notes-for-0.7.6. If you
see anything that is missing from that page, please add it.

Has anyone tested this? I haven't heard anything, so I'll cut the final release tomorrow.

There are actually a few test failures relating to the benchmarks, so I'll probably do a second release candidate.

Here are my test results:

There are quite a few test failures, i.e. stuff like this:

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position
606: ordinal not in range(128)

The benchmark issues should be fixed. 

The autowrap tests are a big mess. Depending on what compilers you have installed and whether or not they work, the tests will pass or fail.

Can you run the tests again in the latest 0.7.6 branch?

Sure, I tested 744b334a70b462823e8ef57e6c672172629d1742:

I had one test failure in plotting:

The doctests fail on these files due to the "default_array":

moorepants@moorepants-2170p:sympy(0.7.6)$ grep -r default_array
doc/src/modules/numeric-computation.rst:    >>> f = lambdify(x, expr, default_array=True)
doc/src/modules/numeric-computation.rst:the next release. For now, setting ``default_array=True`` will provide the
doc/src/modules/numeric-computation.rst:    >>> f = lambdify(x, expr, "numpy", default_array=True)
doc/src/tutorial/basic_operations.rst:will be removed in the next release. For now, setting ``default_array=True``

Apparently some doctests are not run unless numpy, matplotlib, and probably others are installed.  Can you submit a pull request to the release branch fixing this?

I'm going ignore the autowrap stuff, unless someone sends a pull request. I get completely different failures:

We need to make the tests much more robust against broken setups (and I'm not really even convinced that my setup is broken in this case).

So unless I hear anything else I will upload 0.7.6.rc2 in a few hours.  I have fixed the default_array issue.

These test failures are all part of a bigger issue, which is that several tests are not run in Travis CI, because they require certain dependencies to be installed to run. See https://github.com/sympy/sympy/issues/8446.
