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).
