Overview

This is a minor release. The main reason for it is a critical bug fix that causes the software to crash randomly when the language auto-detect option is used (i.e. whisper_lang_auto_detect()).

Other than that, the release includes refactoring of the examples, ruby bindings and some minor changes to the C API.

You can provide feedback in the existing v1.2.0 discussion.

Highlights

Recently, I have been making progress on adding integer quantisation support in the ggml tensor library. This will eventually allow to use quantised models which require less memory and will hopefully run faster. I think the next major release v1.3.0 will officially add quantisation support. For now, you can keep track of the progress in #540
