SymPy 0.7.3 is released

[Aaron Meurer]

I'm happy to announce the release of SymPy 0.7.3. It can be
downloaded from
https://github.com/sympy/sympy/releases/tag/sympy-0.7.3. The release
notes for this release are at
https://github.com/sympy/sympy/wiki/release-notes-for-0.7.3.

To update SymPy, you can use pip install sympy --upgrade or download
the source and use setup.py install. SymPy has no dependencies.

Some highlights:

- Improved integrate() with the Risch algorithm, and it now splits
integrals into Piecewise more often. Support for more special
functions.

- Basic infrastructure for the PDE module.

- Many improvements to the matrix expressions, and assumptions relating to them.

- New context manager for the new assumptions (with assuming(...)).

- This will be the last version of SymPy to support Python 2.5.

- Many bug fixes.

Note: I suspect that these release notes are still not complete. If
you know of any new major change in this release that is not there,
please edit the wiki page and add it.

The following people contributed at least one patch to this release
(names are given in alphabetical order by last name). A total of 85
people contributed to this release. People with a * by their names
contributed a patch for the first time for this release; 56 people
contributed for the first time for this release.

I particularly want to thank Ondrej, who helped set up an
infrastructure for automating this release, without with this release
would not have been possible.

Thanks to everyone who contributed to this release!

Great job!

I clarified the "note" at the end of the page (I've added the word
"below" at the end of the sentence). Let me know if it is clearer now.

Yes. Please modify this in the fabfile where it is automatically generated.

Maybe we need to update the Documentation on the website according to the changes?

[Aaron Meurer]

Which documentation? docs.sympy.org has been updated.

For example, many of the features added to the logic module are not explained in the SymPy docs.

So I guess you should make a pull request. Note that docs.sympy.org is just the docs directory of the SymPy repo.

The download link on the SymPy homepage still points to the code.google.com page which hasn't been updated with the 0.7.3 release it seems.

[Aaron Meurer]

Thanks for pointing that out. Can you take a look at
https://github.com/sympy/sympy.github.com/pull/65. Then we can merge
it, and fix the problem.

I found that file sympy/data/Macports/Profile still 0.7.2, I don't use Macports, is it need update or it is obsolete?

I left it in there, because I didn't really want to deal with the
data/ stuff, but probably that whole directory should be audited.

Anyway, if someone wants to update SymPy on MacPorts now, it's that
much easier :)

    About SymPy 0.7.3, "Plot" (from PyGlet) doesn't show a window at all. For example using "isympy" and typing "Plot(sin(x))" shows a PyGlet window for SymPy 0.7.2/0.7.1 in the same computer.

[Aaron Meurer]

This is likely an accidental regression, since none of us really use
or test Pyglet (I personally uninstalled it from my computer because
bugs in Pyglet were resulting in SymPy test failures).

Could you use the git bisect function to determine the commit that
broke this. In other words, from the SymPy git repo, do

git checkout sympy-0.7.3
git bisect start
git bisect bad
git checkout sympy-0.7.3
git bisect good

And then from there, test if it works, and if it does, type "git
bisect good", and if it doesn't, type "git bisect bad", and repeat
this process until it tells you which commit broke it. If you hit a
commit that doesn't work for some other reason, you can use "git
bisect skip".

^^^ this should be "sympy-0.7.2"

[Roberto Colistete Jr.]

Hi,

A simple solution is to copy "sympy/plotting/pygletplot/* from
SymPy 0.7.2. It works on Maemo 5 (for Nokia N900), which has PyGlet :
http://talk.maemo.org/showthread.php?p=1104168#post1104168

I'll later try the suggestion below to catch the commit with problems.

Best regars,

Roberto Colistete Jr.

[Aaron Meurer]

I attached a diff from doing that. Let me know if you spot the issue.
