There are two main changes for this release.
1. **We are swapping out Google Speech-to-Text for OpenAIs Whisper.**
Specifically, we are using a forked version called [faster-whisper](https://github.com/guillaumekln/faster-whisper). This new speech-to-text model performs much better (ranging from ~3.6% word-error-rate to ~9% word-error-rate on long audio files).
To use this new model efficiently, we need access to a GPU. Since GitHub Actions do not have GPUs available, we are using a system which spins up a Google Cloud Compute Engine instance, connects to it, runs our job, and then tears it down all in the course of a single GitHub Action workflow. From multiple tests, this should be a reduction in cost and processing time however with this release we will do more testing to get a better estimate.
2. **We have switched from MIT to MPLv2 License.**
Unless you are trying to fork our code and take it private, this won't affect you.
