 ## [0.1.5]
 
+### Forth Language
+- **`at` reworked as a looping block**: `at` now captures all stack values as deltas, then re-executes its body once per delta. Closed by `.` (audio emit), `m.` (MIDI emit), or `done` (no emit). Each iteration gets independent nondeterministic rolls (e.g., `0 0.5 at kick snd 1 2 rand freq .` re-evaluates `kick snd 1 2 rand freq` at delta 0 and 0.5).
+- Removed `ArpList` type and `arp` word — arpeggio spreading is now handled by at-loops directly.
+
 ### Added
 
 - Support i32/i16 sample formats at cpal boundary for ASIO compatibility
 
+### Fixed
+- Resolved value annotations deduplicated: nondeterministic ops inside at-loops now show only the last resolved value per span, instead of one annotation per iteration.
+- Audio input device name matching.
