ragleap-voice v0.3.5 release notes

ragleap-voice 0.3.5 (pre-alpha). Every model is still unverified and none is a default.

Fixed

Overlapping Whisper model opens could lose or leak the offline environment variables (HF_HUB_OFFLINE, TRANSFORMERS_OFFLINE). They are now reference counted behind a lock.
Threads sharing one engine through transcribe() or synthesize() could close or reload it under each other. Each engine now has its own lock around load, run and close, so threads on the same shared engine run one after the other; different engines still run in parallel. Transcriber keeps its own engine and lock.
Registry.register takes a lock, so two threads cannot both register the same name.

Notes

Versions 0.3.4 and earlier have these races. Defaults and the public API are unchanged.
Not covered: other code changing the process environment while a model is opening, and thread safety inside faster-whisper itself (not checked).
An engine must not call transcribe() or synthesize() from inside its own run().
