Version 1.6.2

• Fixed a memory leak when using callbacks.
• Linting, fixed typos, and similr by @alexfikl .

Version 1.6.1

• Updated build system and added linting, CI, and similar by @alexfikl.
• Improvements to documentation.

Version 1.6.0

• Implemented callbacks.

v1.5.0

• Added SymPy symbols for y and t (as an alternative to SymEngine symbols).
• Implemented quick installation test.
• Several improvements to error messages and documentation.

Version 1.4.0

• Implemented dictionaries which (using the dynamical variables as keys) for:
  • defining differential equations
  • setting the initial conditions
  • obtaining the state

Version 1.3.1

• Improvements to documentation.
• Fixed wrong dependency in v1.3.0.

Version 1.2

• Support for Stratonovich SDEs (except for jumps).

Version 1.0.1

There now is a SymEngine version number to refer to as a dependency – which means that automatically installing this dependency should work and you do not have to build SymEngine on your own anymore.

Version 1

• Switched from SymPy to SymEngine as a backend, which may speed up code generation by a factor of up to nine hundred. Almost everything that worked before should still work. See SymPy vs. SymEngine for details. As a required Symengine release is pending, you have to build it from source for now.
• Added OpenMP support.
• Fixed a nasty memory leak.
• Changed some default parameters and behaviours.
• Dropped support of some old, rarely used syntax.
• Dropped Python 2 support.

0.22

• Fixed a crucial bug in the integrator (for non-additive SDEs) that passed unnoticed due to a bug in a test.

This will be probably the last release using SymPy for symbolics. The next one will use SymEngine.

This will also probably be the last release supporting Python 2.
