This release is really only an incremental change in terms of functionality. It's added history, which can be useful when interfacing with other programs, and allows defining multiple trigger paths as well as multiple trigger words. Both useful additions, but no real change to the core functionality. There is also now an output.log file generated by the whisper.exe meaning you can see the logs without having to run the GUI. Again, no real change to functionality, but can be a nice little QOL feature.
The big change however is in the app structure, I've learned a lot since I started building this (Can you believe my idea of "version control" was keeping whole copies of the previous files in a different directory? I too am shocked it worked at all) and the previous structure was a mess. This has been updated to a nice modular layout that makes it much easier to play with and tweak without breaking the whole thing.
There is also now a dedicated build.py file, that should build the exe files for you if you want to edit it and rebuild it yourself.
