<Update label="v1.3.1" tags={["Features", "Fixes"]} rss={{ title: "Embody v1.3.1", description: "Changelog:" }} description={<Subtitle variant="changelog">January 2026</Subtitle>}>
  ## v1.3.1

  <ScrollBox maxHeight="250px" showHint={true}>
    * Remote ops parity: richer `/meta`, config push, and `upgrade/rollout` support.
    * Encrypted game image: staged rollout (prefetch) + pending rollout state; persist last verify in `/meta`.
    * CLI: repo auto-update on launch (ff-only, best-effort; opt-out via `EMBODY_CLI_NO_AUTO_UPDATE=1`); remove `cluster deploy --no-update`.
    * Remote ops: pin orchestrator to `{ref, service_image_tag}` and apply safely during sleep (`--no-start`).
    * consume.sh: more robust base64 decode detection.

    ### Upgrade / install

    ```bash theme={"theme":{"light":"github-light","dark":"dark-plus"}}
    git clone https://github.com/its-DeFine/Unreal_Vtuber.git
    cd Unreal_Vtuber

    git fetch --tags
    git checkout v1.3.1

    # If you ever see GHCR "denied" pulling the game image:
    sudo ./scripts/embody_cli.sh rollout
    ```

    ### Start cluster (auto)

    ```bash theme={"theme":{"light":"github-light","dark":"dark-plus"}}
    sudo ./scripts/embody_cli.sh cluster deploy --auto --yes --pull missing
    ```

    ### Capacity mental model (developer notes)

    * The unit of allocatable capacity is a **signaling server registration**. Each cluster slot contributes one.
    * Cluster mode is deterministic:
      * Signaling port: `8080 + slot`
      * Runner port: `9877 + slot`
      * Recorder-control port: `8889 + slot`
    * Per-slot sleep/wake is supported via `/power/projects/{project}` (and CLI wrappers).

    ### Defaults & knobs

    * CLI repo auto-update is on by default; disable with `EMBODY_CLI_NO_AUTO_UPDATE=1` (auto-update is skipped automatically when the repo is dirty or on detached HEAD).
    * CLI auto-upgrade-when-sleeping is on by default; disable with `EMBODY_CLI_AUTO_UPGRADE_WHEN_SLEEPING=0`.
    * Service containers (runner/health/rotator/etc) can be pinned to a release tag via `EMBODY_SERVICE_IMAGE_TAG=v1.3.1` in `.env` (remote ops can also set `service_image_tag` via `/ops/upgrade`).
    * Remote ops endpoints are enabled by default (`EXPERIMENTAL_REMOTE_OPS=1`); opt out with `EXPERIMENTAL_REMOTE_OPS=0` and recreate `orchestrator-health`.
    * Remote cluster control (`/cluster/*`) is opt-in: set `EXPERIMENTAL_REMOTE_CLUSTER_CONTROL=1` and recreate `orchestrator-health`.
