 * [#183](https://github.com/slack-ruby/slack-ruby-bot-server/pull/183): Add a `config.server_pages` block to configure page middleware options centrally without changing the installed library's defaults - [@dblock](https://github.com/dblock), [@Copilot](https://github.com/apps/copilot-swe-agent).
 * [#184](https://github.com/slack-ruby/slack-ruby-bot-server/pull/184): Add a configurable API application and separately mountable team read/registration endpoints, preserving the default API while supporting custom routes and registration-only applications - [@dblock](https://github.com/dblock), [@Copilot](https://github.com/apps/copilot-swe-agent).
+* [#185](https://github.com/slack-ruby/slack-ruby-bot-server/pull/185): Skip inactive installations in status checks and deactivate revoked credentials through service callbacks, returning an explicit failed ping instead of failing the whole status response - [@dblock](https://github.com/dblock), [@Copilot](https://github.com/apps/copilot-swe-agent).

 Upgrading Slack-Ruby-Bot-Server
 ===============================
 
+### Upgrading to >= 2.3.0
+
+#### Status Checks and Inactive Installations
+
+`GET /api/status` now pings only active installations. When Slack returns `account_inactive` or `invalid_auth`, the installation is deactivated through `Service#deactivate!`, and the endpoint returns HTTP `200` with `ping: { "ok": false, "error": "account_inactive" }` (or `"invalid_auth"`). The active-team count reflects that deactivation. Monitoring should inspect the failed `ping` as well as the HTTP status.
+
+When no active installations remain, no Slack ping is attempted. Other Slack errors retain their existing error response and do not deactivate installations.
+
