+The Scalatra team is pleased to announce the release of version 3.1.0 of the framework.
+
+<!--more-->
+
+Scalatra 3.1 is compatible with Scalatra 3.0 but supports Servlet 6.0.0 and Jetty 12.0.x.
+
+You need to specify the suffix of artifacts depending on which version you use ervlet 4.0.1 (javax) or 6.0.0 (jakarta):
+
+```scala
+// for javax
+"org.scalatra" %% "scalatra-javax" % "3.1.0",
+"org.scalatra" %% "scalatra-json-javax" % "3.1.0",
+"org.scalatra" %% "scalatra-forms-javax" % "3.1.0",
+...
+
+// for jakarta
+"org.scalatra" %% "scalatra-jakarta" % "3.1.0",
+"org.scalatra" %% "scalatra-json-jakarta" % "3.1.0",
+"org.scalatra" %% "scalatra-forms-jakarta" % "3.1.0",
+...
+```
+
+Also, many libraries are upgraded in Scalatra 3.1.0 but there are no code level imcompatibility, so you can still refer to Scalatra 3.0 documentation and examples for Scalatra 3.1.
