 - Doctor/config: restore legacy group chat config migrations for `routing.allowFrom`, `routing.groupChat.*`, and `channels.telegram.requireMention` so upgrades keep WhatsApp, Telegram, and iMessage group mention gates and history settings instead of leaving configs invalid or silently blocked. Thanks @scoootscooob.
 - CLI/update: make package-update follow-up processes write completion results and exit explicitly, so Windows packaged upgrades do not hang after the new package finishes post-core plugin work. Thanks @vincentkoc.
 - Release validation: skip Slack live QA unless Slack credentials are explicitly configured, so release gates can keep proving non-Slack surfaces while Slack is still local and credential-gated. Thanks @vincentkoc.
+- Plugins/update: treat OpenClaw CalVer correction versions like `2026.5.3-1` as satisfying base plugin API ranges, so correction builds can install plugins that require the base runtime API. Fixes #77293. (#77450) Thanks @p3nchan.
 - fix(gateway): clamp unbound websocket auth scopes [AI]. (#77413) Thanks @pgondhi987.
 - Gate zalouser startup name matching [AI]. (#77411) Thanks @pgondhi987.
 - Active Memory: send a bounded latest-message search query to the recall worker so channel/runtime metadata does not become the memory search string. Fixes #65309. Thanks @joeykrug, @westley3601, @pimenov, and @tasi333.
