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 client and server are rejected at connection time with 5004 ProtocolVersionMismatch.

Versions

  • Unreleased

    In development, not yet shipped. Nothing has landed for the next release yet.

  • v0.5.0

    Composable, game-driven turns: the per-turn slot blackboard, agent variables, model-visible tool results, GBNF grammar constraints, dialog-history editing, KV-cache control, and the Unreal graph editor.

  • v0.4.0

    Mandatory one-shot CreateSession, mid-turn cancel / pause / resume, chat-template-driven tool calling, voice cloning and multilingual TTS.

  • v0.3.0

    Server-side voice output (TTS), the Unity workflow graph editor and Model Manager, the bundled server, and file-path storage.

How to read a version page

  • Highlights — the marquee capabilities, each linking to the guide or reference page that covers it.
  • Themed sections — every user-visible change, grouped by area.
  • Breaking changes and behavior changes — what breaks and how to migrate. Always read this before upgrading.
  • New error codes — codes that first appear in that release. The full catalog lives in Error Codes.
