# Upstream whisper-rs 0.16.0 (latest release) has two open callback bugs
# (codeberg.org/tazz4843/whisper-rs issues 277/271, fix PR 278) and
# vendors whisper.cpp 1.8.3. The `vendor/whisper-rs-0.16.0-patched`
# branch of this repo carries the published 0.16.0 with the callback
# and CString-leak fixes plus the whisper.cpp submodule at v1.8.6. Drop
# both patches once a whisper-rs release lands the fixes and re-vendors
# (issue #26). Known upstream design holes left untouched (unreachable
# from this crate, which never clones FullParams): cloning a FullParams
# shares the installed closures and grammar pointers across clones.
