+## [1.61.1] — 2026-10-11
+### Fixed
+- **Per-model speaker embeddings stay with their voice:** the TTS engine's `<name>.1.7b.pt` / `<name>.0.6b.pt` files that sit beside the WAV are now part of the voice package, so hiding, unhiding, trashing, deleting and renaming a voice moves, removes or renames them too instead of leaving orphans in `active_voices`.
+- Custom TTS engines no longer count as available just because the app's own voice library is non-empty: availability follows the engine's health, so a stopped VoiceDesign/CustomVoice container is no longer listed.
+
+---
+
 ## [1.61.0] — 2026-10-11
 ### Added
 - **My Voices list header:** a sort header (select-all/none checkbox with a partial-selection state, then sortable Name / Lang / Gender / Speed / Rating with the active column highlighted) sits directly above the voice list, and the filter row starts with a filter icon. The full table header still takes over in table view.
