Release Notes

One page per version, newest first. Each page lists the release's highlights by theme, its breaking changes and behavior changes, and any new error codes — read the breaking-changes section of every version between the one you shipped and the one you are upgrading to.

Tryll is in pre-release: expect breaking changes until the 1.0 API freeze. A release that changes the wire protocol requires rebuilding your integration against the new schema; mismatched peers fail at connect: the client rejects the server's protocol version with 5004 ProtocolVersionMismatch.

  • v0.9.0

    One voice per agent with delivery modes you switch mid-turn, LoRA adapters on LLM nodes, multi-attribute classification in one call, localized prompts from your own string tables, Qwen3-TTS voice cloning, Agent Log export, and new Use Cases and Model Benchmarks sections.

  • v0.8.0

    Rolling conversation summaries, experimental agent-written memory with game-memory saves, viseme lip sync for ARKit faces and MetaHumans, client-sent voice turns with per-model hotword biasing, faster first audio in more languages, a user model catalog, deployment modes with one storage root, and per-NPC events.

  • v0.7.0

    Dialog you can put in your save file, one session language for speech, content and prompts, per-model RAM/VRAM placement with engines taken from the catalog, pause timeouts, the Orpheus and Maya1 voices with natural-language voice direction, measured tool-call model rankings, live server RAM/VRAM in the editor, and intent classification from described labels instead of a labelled corpus.
