The Apache Tomcat Project is proud to announce the release of version 10.0.5 of Apache Tomcat. This release is targeted at Jakarta EE 9.

Applications that run on Tomcat 9 and earlier will not run on Tomcat 10 without changes. Java EE applications designed for Tomcat 9 and earlier may be placed in the $CATALINA_BASE/webapps-javaee directory and Tomcat will automatically convert them to Jakarta EE and copy them to the webapps directory. This conversion is performed using the Apache Tomcat migration tool for Jakarta EE tool which is also available as a separate download for off-line use.

The notable changes in this release are:

• Fix a regression in 10.0.4 that meant that an error during an asynchronous read broke all future asynchronous reads associated with the same request instance.
• Prevent concurrent calls to ServletInputStream.isReady() corrupting the input buffer.
• Update the packaged version of Tomcat Native to 1.2.27 to pick up binaries built with OpenSSL 1.1.1k.

Full details of these changes, and all the other changes, are available in the Tomcat 10 changelog.
