Can I just downgrade back to v2026.3.13?

While downgrading is possible, it is messy due to potential config schema changes. Using the local install workaround mentioned above is safer and keeps your current environment intact.

Does this affect all plugins?

No, this is specific to plugins that register new channels (like Matrix). Standard helper plugins remain unaffected.

Is there an official patch coming?

Yes, the fix has been merged into the main development branch. Expect it to be included in the next automated update.

Fix Matrix Plugin API Version Mismatch in OpenClaw

TL;DR — Quick Fix

The upgrade removed the built-in matrix channel before plugin registration completes; resolve this by manually installing the plugin from the latest source code.

Matrix Plugin API Version Mismatch After Upgrade to v2026.3.22

What's Happening

You upgraded to v2026.3.22 and now you're stuck. Running openclaw doctor --fix cleans up your config but breaks the Matrix plugin because the system expects a channel that no longer exists in the core. You're caught in a loop where the config is invalid, but you can't install the plugin to make it valid again.

The Fix

The current fix is to bypass the broken plugin manager version and pull the latest code directly from the repository fix. Do not rely on the standard install command until the next point release. Run these commands to pull the latest fix from the official repository and link it:

Clone the repository locally: git clone https://github.com/openclaw/openclaw.git
Navigate to the matrix plugin directory.
Run openclaw plugins install ./path/to/matrix/plugin to manually register the plugin.

Once the local version is registered, the config validator will recognize the Matrix channel and resolve your startup errors.

Why This Occurs

In v2026.3.22, the CHAT_CHANNEL_ORDER logic was refactored. The core no longer includes the Matrix channel by default; it is now strictly handled by the plugin. The config validation runs before the plugin subsystem fully initializes. If your config file references a Matrix channel, the validator throws an "unknown channel id" error, which blocks the plugin installation that would have fixed the channel ID in the first place.

Prevention

Always verify breaking changes in the migration tutorials before running openclaw update. When dealing with plugin-dependent channels, wait for the secondary doctor sync to finish before running doctor --fix. If you are using Docker or restricted environments like Raspbian, avoid major version upgrades on production nodes until at least two point releases have passed to ensure plugin compatibility catches up with core refactors.
