# YazSes v2.4.0-dev.2 — Wave H complete (developer preview)

**Pre-release · not published** (publish workflows are pinned to `v0.x`/`v1.x`; v2 dev tags do
not ship). **v1.4.1 remains the stable release.** Every feature is **OFF by default**.

Completes **Wave H** — the full 10-feature SoA round from `design/vision/v2-research/10-wave-h.md`
(ADRs `adr-v2-055..064`). Adds the four features beyond the `dev.1` ship-now tier:

## New since dev.1 (all off by default)

- **Ambient Audio-Event Guard** (ADR-v2-061, `[audioguard]`) — auto-pauses dictation (or alerts)
  when it hears a doorbell / phone / alarm / your name. Classifier behind `soundawareness`.
- **On-Device Condense** (ADR-v2-062, `[condense]`) — a condense variant inserts a tightened
  summary of your own long dictation instead of the verbatim text.
- **Slot-Filling Dictation** (ADR-v2-063, `[slotfill]`) — one utterance fills a named-field
  template ("high priority, affects Firefox" → the right fields).
- **Few-Shot Command Spotter** (ADR-v2-064, `[cmdspotter]`) — enroll a few examples of short
  commands ("send", "stop") that fire instantly without a full decode. Encoder behind `kws`.

Plus the six `dev.1` ship-now features: Emoji & Symbol by Voice, Voice Unit Conversion, Spoken
Temporal Normalizer, Mid-Utterance Self-Repair, Spoken Spreadsheet, Clipboard-History by Voice.
`yazses features` now lists **75 capabilities**.

## Quality
1202 tests green across Linux × macOS × Windows on Python 3.11 and 3.12. Every Wave H pure core
is unit-tested to 100%; heavy models (PANNs, abstractive LLM, SpeechLLM, KWS encoder) stay lazy
behind optional extras. The default install and the v1 dictation path are unchanged.
