Hi Nathan, Have you tried out SymEngine with it? On Thu, Jul 6, 2017 at 3:18 PM, Nathan Goldbaum wrote:

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).
