4.3.1 is a bugfix release, with a few minor fixes to library code, notably:
- Fix the creation of the
RGN_OUTER_X
region - Several small bugs in the Python API
- Preserve restart files if there's a crash during initialisation
- Fix some segfaults in the PvodeSolver
- Fix some issues with Hypnotoad (see #1783)
Other changes are mostly housekeeping changes for the BOUT++ project.
