Improvements to the output mutators necessitated a change in function signature, so this is getting a new major version.
It is strongly recommended that consumers of this library upgrade, as it includes fixes.
Full Changelog: v3.0.0...v4.0.0
NOTE: This is unrelated to this release, but at that this time the transifex-python library does not work with Python>=3.12. The issue (which has no traction) is here. For now you'll need to use an older Python.
On Windows, with Scoop, this can be done like so:
c:\Users\<user>\scoop\apps\python\3.11.5\python.exe -m pipenv install --ignore-pipfile
