docs/contributing/about-version-numbers.md
There are several places in the wxWidgets source tree that define the version number for the library.
The script misc/scripts/inc_release can be used for incrementing the release
field of the version, i.e. changing 2.8.x to 2.8.x+1 but it does not take
care of version.bkl and can't be used for changing the other version
components, this needs to be done manually. It also doesn't update
version.bkl file which always needs to be updated manually, follow the
instructions there.
Here is the list of files that need to be updated:
Do not forget to rebake everything after updating version.bkl!
Version should be updated immediately after releasing the previous version so that the sources in the repository always correspond to the next release and not the past one.
