[yt-dev] Fwd: [sympy] SymPy 1.1 is released

[Nathan Goldbaum]

Hi all,

I tested yt with the release candidate and didn't run into any issues.
We're using very stable parts of the sympy API so I'm not expecting
breakage. That said, if anyone notices issues related to this please let me
know and I will fix ASAP.

I'm happy to announce that SymPy 1.1 has been released. You can install it
with

    pip install -U sympy

It also be available via conda soon.

This is a major release of SymPy, with many major changes since the
previous version, 1.0. The release notes are at
https://github.com/sympy/sympy/wiki/Release-Notes-for-1.1 (note, at
the time of this writing, these are still being updated).

Please report any bugs you find in our issue tracker
https://github.com/sympy/sympy/issues

Some highlights (if I am missing anything major, please let me know
and update the release notes page):

- Many improvements to code generation, including addition of
tensorflow (to lambdify), C++, llvm JIT, and Rust language support, as
well as the beginning of AST classes.

- Experimental support for SymEngine as a symbolic core in the
sympy.physics.mechanics module (set the environment variable
USE_SYMENGINE=1).

- A reworking of the internals of the matrices module.

- Several bug fixes for floating point numbers using higher than the
default precision.

In addition, several improvements from the 2016 Google Summer of Code
projects, including:

- A new holonomic submodule, for computing with holonomic functions
(Shubham Tibra's GSoC project).

- Improvements to the group theory module (Gaurav Dhingra's GSoC project).

- Improvements to the solvers and solveset (Shekhar Prasad Rajak and
Kshitij Saraogi's GSoC projects).

- Implementation of Singularity Functions to solve Beam Bending
problems (Sampad Kumar Saha's GSoC project).

- Improvements to the mechanics module (James Brandon Milam's GSoC project).
