On Settings → Plugin installations → (installation) you can now edit the Callback URL directly from the overview. Previously the callback URL could only be set when the installation was first created and was read-only afterwards.
Click Edit callback URL, enter the new address, and save. Leaving the field empty clears the URL and disables webhook delivery for that installation without uninstalling it. Editing is available in any installation status — webhooks still only dispatch while the installation is active, so you can set the URL ahead of re-activating a suspended install. Bound API keys are unaffected and do not need to be rotated.
