Full Release Notes

Backport of word-level timestamp fixes from v3.8.4.

## Bug Fixes

- **Restore timestamps for unalignable characters** (39aa9f5): Words containing digits, symbols, or foreign script (e.g. `4,9`, `£13.60`) now get proper timestamps via a wildcard emission column. The previous patch (v3.X.Y) reverted PR #986 which removed wildcard support entirely. Fixes #1372.

## Testing

- Add regression test for #1372 (da072d6)
- Add pytest dev dependency and CI test workflow (f9a3f8f)
