v0.3.3

Nexus v0.3.3

Stable — maintenance & polish. Promotion of v0.3.3-beta.1 after its validation window; cumulative changes on top of v0.3.2. A reliability, behaviour-polish, and slimming release. It makes imported character cards actually drive chat, adds a cloud→local voice-recognition fallback, fixes a cluster of voice/notification/persona bugs, changes a couple of pet defaults for the better, and removes ~2,500 lines of dead/dormant code. No major new feature surface — the bigger autonomy work is tracked separately for v0.4. Stable and beta users auto-upgrade on next launch.

What changes for users

Desktop pet

• Default pet renamed to “Pip.” The bundled sample sprite pet (previously shown as “Terminal Pet”) is now Pip, and its description makes clear it’s a sample/test pet demonstrating the sprite-pet system — still a fine default to start from.
• Pets now show their scene backdrop by default. Sprite pets used to default to free-roam mode (transparent background, character only). They now default to fixed mode with the time-of-day backdrop. The transparent “roam the whole desktop” mode is now opt-in — toggle it from the new setting (Settings → pet) or the pet’s right-click menu. (If you previously relied on the transparent default, just switch the toggle on.) Pets you had explicitly set are unaffected.
• A new in-app free/fixed toggle for sprite pets (previously only available on the right-click menu).
• The “spawn clone (分身)” feature was removed. The right-click options to spawn/dismiss extra roaming pet windows are gone; the single companion is unaffected.
• Hidden pets no longer burn CPU/battery — locomotion is paused while the window is hidden.

Voice

• Cloud→local speech-recognition fallback. When cloud transcription fails and you’ve enabled failover, Nexus now falls back to the fully-offline local SenseVoice model for that utterance (continuous/VAD path).
• A long continuous utterance no longer gets silently dropped (and no longer leaves voice stuck) — it’s flushed and transcribed.
• Barge-in no longer mistakes the assistant’s own tail audio for new user speech.

Persona & character cards

• Imported Character Cards can now drive chat. Previously an imported card only shaped the autonomy/letters surface; the chat replies still used the global persona. With the new per-profile-persona setting enabled, the active card’s soul/personality drives chat too.
• An imported card no longer leaks a [Character card: …] placeholder into the prompt — the real assembled persona is used.
• Live2D models now keep their authored surprised / confused / embarrassed expressions (they were being silently dropped). Added docs on the Live2D auto-discovery naming/order conventions.

Notifications

• Chinese urgency keywords (立即 / 紧急 / 重要 / 立刻) are now correctly prioritized — they were always being downgraded to normal priority.

Reliability fixes

• Chat requests now retry once on a transient 429/5xx before surfacing a failure (helps under provider rate-limits).
• SSRF redirect-following is now revalidated per hop on the chat/voice connection-test and model/voice-list probes.
• Fixed a regression where the panel-sent always-on-top / click-through toggles silently no-op’d.
• Fixed timezone-dependent flakiness in the usage/cost history.

Under the hood

• ~2,500 lines of dead/dormant code removed: orphaned test-only modules and barrels, the dormant realtime-voice backend (gated behind an off-by-default flag), the unused agent-workspace fs-tools stack, a dead inter-plugin delivery path, and duplicate/stub files.
• Dropped the unused protobufjs dependency.

Known issues

• Screen Recording permission on the unsigned build. Because the app isn’t code-signed, macOS TCC may not list Nexus under System Settings → Privacy → Screen Recording until it actually requests capture. The default-off “desktop awareness” (screen OCR) is the only thing that requests it; turn that on (or use right-click → Open + remove the quarantine attribute) to get the prompt. Microphone behaves the same. Deferred to a future signed build.
• Deferred internal cleanup (no user impact): ~291 unused i18n keys and a small tail of dead exports are not yet pruned; planned for a follow-up.

Notes & limitations

• Unsigned distribution (macOS arm64). First launch needs the usual right-click → Open; granting Microphone / Screen Recording follows the in-app prompts. Unchanged in v0.3.3.
• The “Codex pet” gallery/import/creator feature keeps its name — it integrates with the external codex-pet.org / CodexPets.net community ecosystem and is not Nexus-branded.
• Identical content to v0.3.3-beta.1 — no code changes between the beta and this stable tag. The larger messaging-bridge work that landed after the beta cut ships separately in the v0.3.4 beta line.
