+---
+
+Apache Camel 4.20 has just been [released](/blog/2026/04/RELEASE-4.20.0/).
+
+This release is an expedited security fix release on top of the previous [4.19 release](/blog/2026/04/camel419-whatsnew).
+
+## JDK25 compatibility
+
+This is the first release supporting JDK25. 
+
+However, there are a few 3rd party libraries that does not yet fully support JDK25, 
+see more in [CAMEL-22114](https://issues.apache.org/jira/browse/CAMEL-22114).
+
+## Camel JBang
+
+You can now easier configure HTTPS for development purposes with self-signed certificates, so you can host services
+via HTTPS locally in Camel. 
+
+```properties
+# use https instead of http with self-signed certificate
+# making it easy for development purpose
+camel.ssl.enabled=true
+camel.ssl.selfSigned=true
+```
+
+## Upgrading
+
+Make sure to read the [upgrade guide](/manual/camel-4x-upgrade-guide-4_20.html) if you are upgrading from a previous
+Camel version.
+
+If you are upgrading from, for example, 4.4 to 4.8, then make sure to follow the upgrade guides for each release
+in-between, i.e.
+4.4 -> 4.5, 4.5 -> 4.6, and so forth.
+
+The Camel Upgrade Recipes tool can also be used to automate upgrading.
