+## 5.0.0 (October 16, 2025)
+  * **Concurrency & Stability Fixes:**
+    * Refactored message publisher to use thread-local AMQP channels, resolving timeouts during high-throughput parallel processing.
+    * Corrected a race condition in the graceful shutdown logic to prevent `Connection pool shut down` errors when stopping the component during an active HTTP request.
+  * **HTTP Client Improvements:**
+    * Implemented a singleton strategy for the HTTP client to reuse connections and improve performance.
+    * Stabilized large message (lightweight) streaming by setting the `Content-Length` and disabling the `Expect-Continue` handshake, preventing `Connection reset` errors.
+    * Added a retry mechanism for `408` (Request Timeout) and `5xx` server errors.
+  * **Logging Enhancements:**
+    * Resolved logging conflicts that caused erroneous messages, duplicate or empty log messages.
+    * Improved logging for large message uploads to include the message's context (e.g., "main message body", "passthrough") and its size.
+    * Moved several verbose logs from `INFO` to `DEBUG` level for a cleaner default log output.
+  * **Dependencies:**
+    * Upgraded core dependencies, including Guice from v5 to v7.

 3. If you want to test new sailor version, just push changes to your feature branch. If you push any changes to the Sailor GitHub repository with X.X.X-SNAPSHOT, circle.ci will automatically upload the SNAPSHOT version to Sonatype repository. 
 After CI job will be done you can use `4.0.0-SHAPSHOT` version in the components.

 5. To publish stable release version create GitHub release with tag **4.0.0**. This will trigger CI pipeline to publish release version to the Production maven repository.
