+# 5.5.1
+
+## Enhancements
+
+- [#12497](https://github.com/emqx/emqx/pull/12497) Improved MongoDB connector performance, resulting in more efficient database interactions. This enhancement is supported by improvements in the MongoDB Erlang driver as well ([mongodb-erlang PR](https://github.com/emqx/mongodb-erlang/pull/41)).
+
+## Bug Fixes
+
+- [#12471](https://github.com/emqx/emqx/pull/12471) Fixed an issue that data integration configurations failed to load correctly during upgrades from EMQX version 5.0.2 to newer releases.
+
+- [#12542](https://github.com/emqx/emqx/pull/12542) Redacted authorization headers to exclude basic authorization credentials from debug logs in the HTTP Server connector, mitigating potential security risks.
+
+- [#12598](https://github.com/emqx/emqx/pull/12598) Fixed an issue that users were unable to subscribe to or unsubscribe from shared topic filters via HTTP API.
+
+  The affected APIs include:
+
+  - `/clients/:clientid/subscribe`
+  - `/clients/:clientid/subscribe/bulk`
+
+  - `/clients/:clientid/unsubscribe`
+  - `/clients/:clientid/unsubscribe/bulk`
+
+- [#12601](https://github.com/emqx/emqx/pull/12601) Fixed an issue where logs of the LDAP driver were not being captured. Now, all logs are recorded at the `info` level.
+
+- [#12606](https://github.com/emqx/emqx/pull/12606) The Prometheus API experienced crashes when the specified SSL certificate file did not exist in the given path. Now, when an SSL certificate file is missing, the `emqx_cert_expiry_at` metric will report a value of 0, indicating the non-existence of the certificate.
+
+- [#12608](https://github.com/emqx/emqx/pull/12608) Fixed a `function_clause` error in the IoTDB action caused by the absence of a `payload` field in query data.
+
+- [#12610](https://github.com/emqx/emqx/pull/12610) Fixed an issue where connections to the LDAP connector could unexpectedly disconnect after a certain period of time.
