v0.13.0 — T3 Code update channels
T3 Code can now be upgraded directly from Setup → Environment without replacing or restarting the container. Choose Stable or Nightly, check the latest published release, and confirm when to install. Switch back to Stable whenever you prefer. Updates within a channel never downgrade a newer installed version.
Only the T3 Code process restarts; Setup and the container stay running. Active agent turns and T3 terminals stop during activation, and open clients reconnect. The installed version and release channel persist on the home volume across restarts and image upgrades.
Downloads use the official architecture-specific package, verify its SHA-512 integrity, and check launcher compatibility before stopping the current server. SQLite snapshots and the native prepared/commit handshake protect activation: a failed, timed-out, or interrupted trial restores the previous version and database. Progress, errors, and retry controls are shown in Setup.
Upgrade your container image once to v0.13.0 to enable this feature. Later T3 Code updates can happen inside the container. Setup, OS dependencies, and future supervisor requirements still update through images. The bundled Stable release remains T3 Code 0.0.45.
Current Stable and Nightly use different thread databases. Both histories are kept, but returning to Stable can show earlier history. Some devices may need pairing again when the releases use different signed credential permissions. Pairing records and revocations transfer across compatible schemas; a switch is refused if it would broaden a restricted credential's permissions. The confirmation explains these consequences before installation.
Images for Linux amd64 and arm64:
- Browser:
ghcr.io/dizys/t3code-docker:0.13.0or:0.13.0-browser - Core:
ghcr.io/dizys/t3code-docker:0.13.0-core - The
latest,browser,full,core, andslimtags point to this release.
All 364 Node tests pass. Each platform image passed its smoke tests; both amd64 variants passed the real agent lifecycle tests before publication. Release manifests were verified against the tested image digests. A real Stable → Nightly → Stable round trip and eight responsive browser contexts were also verified; screenshots and the recording are in the PR.
