We have released new bug fix releases for Brian 2 (version 2.1.2) and Brian2GeNN (version 1.1.5).
The new Brian 2 release fixes two bugs:
- an incorrect application of the substitution mechanism in equations (i.e. when using the same set of equations several times and changing the equations' variable names via Brian's Equation class), and
- an inadvertent deactivation of parts of the new caching mechanism which resulted in a major reduction of its performance improvement.
