v0.46.0

Breaking Changes

• State/type registries moved to hassette.conversion — STATE_REGISTRY and TYPE_REGISTRY are now owned by hassette.conversion instead of hassette.models. Imports from hassette.models still work via re-exports but are deprecated; update to from hassette.conversion import STATE_REGISTRY, TYPE_REGISTRY. (#1122)

Apps

• autostart config option — register an app without starting it at boot. enabled = true, autostart = false registers the app, shows it in the dashboard, and leaves it startable on demand, with enabled still the hard on/off switch. These apps get a "no autostart" chip in the UI and a new Autostart column in hassette app. (#1124)

Bus

• Per-listener backpressure policy — each subscription chooses block (default; wait for a dispatch slot, unchanged behavior) or drop_newest (skip the event when the bus is saturated). Drop counts surface in the listener detail view. (#1082)
• Bounded concurrent dispatch — new lifecycle.max_concurrent_dispatches config field (default 50) caps how many handler invocations run at once, so a Home Assistant state storm can no longer fan out into unbounded tasks and exhaust memory. (#1075)

State Models

• Presence helpers on StateManager — anybody_home(), everybody_home(), nobody_home(), and is_home(entity_id), accessed via self.states. Each reads the local state cache synchronously (no await, no network round-trip) and checks the person domain, falling back to device_tracker when no person entities exist. (#1130)
• Domain-typed state access (self.states.light["x"] / .get("x")) now raises UnableToConvertStateError on a conversion failure instead of leaking a raw pydantic.ValidationError. Code catching ValidationError from domain-typed access should catch UnableToConvertStateError instead. (#1109)

Bug Fixes

• Manual app reload picks up fixed code — the REST/UI Reload action now forces a fresh module re-import, so an app that failed to start no longer keeps failing with the original error after you fix the source on disk. Matches the file-watcher's behavior. (#1110)
• config_log_all_events respects hot-reload — it was frozen after the first dispatched event and silently ignored config changes; it now updates live like config_log_level. (#1088)
• Cold-start state retry now fires — StateProxy.yield_domain_states was retrying a generator object rather than the readiness check, so the @retry never re-ran before the state cache was ready. (#1088)
• Wiring guards survive python -O — service-wiring assert statements (stripped in optimized Docker images) are now real runtime checks. (#1088)
• Per-section app manifests no longer clobber each other — two [apps.*] sections referencing the same App subclass kept distinct display_name/enabled/auto_loaded; the manifest is now per-instance instead of a shared class attribute. (#1069)
• Resources that already reached a terminal state are no longer driven to FAILED during teardown — a late submit-after-shutdown on an already-STOPPED resource is a benign no-op, silencing a spurious strict-mode warning. (#1071)
