The notable changes in this release are:$$$$$$Remove the requirement that an MD5 implementation must be provided by JRE.$$$Improve the handling of %nn URL encoding in the RewriteValve$$$Various improvements to the JsonErrorReportValve$$$$$$Full details of these changes; and all the other changes; are available in the Tomcat 11 changelog - https://tomcat.apache.org/tomcat-11.0-doc/changelog.html#Tomcat_11.0.6_(markt)

Tomcat 11.0.5 (markt)$$$Catalina$$$Fix: When looking up class loader resources by resource name; the resource name should not start with /. If the resource name does start with /; Tomcat is lenient and looks it up as if the / was not present. When the web application class loader was configured with external repositories and names starting with / were used for lookups; it was possible that cached not found results could effectively hide lookup results using the correct resource name. (markt)$$$Fix: Enable the JNDIRealm to validate credentials provided to HttpServletRequest.login(String username; String password) when the realm is configured to use GSSAPI authentication. (markt)$$$Fix: Improve the checks for exposure to and protection against CVE-2024-56337 so that reflection is not used unless required. The checks for whether the file system is case sensitive or not have been removed. (markt)$$$Fix: Fix a bug in the JRE compatibility detection that incorrectly identified Java 19 and Java 20 as supporting Java 21 features. (markt)$$$Add: Add support for logging the connection ID (as returned by ServletRequest.getServletConnection().getConnectionId()) with the AccessLogValve and ExtendedAccessLogValve. Based on pull request #814 by Dmole. (markt)$$$Fix: Avoid scenarios where temporary files used for partial PUT would not be deleted. (remm)

Tomcat 11.0.4 (markt)$$$Catalina$$$Fix: 69576: Avoid possible failure intializing JreCompat due to uncaught exception introduced for the check for CVE-2024-56337. (remm)$$$Other$$$Add: Add org.apache.juli.JsonFormatter to format log as one line JSON documents. (remm)

Tomcat 11.0.2 Released$$$The Apache Tomcat Project is proud to announce the release of version 11.0.2 of Apache Tomcat. This release implements specifications that are part of the Jakarta EE 11 platform.$$$$$$Users of Tomcat 10 onwards should be aware that; as a result of the move from Java EE to Jakarta EE as part of the transfer of Java EE to the Eclipse Foundation; the primary package for all implemented APIs has changed from javax.* to jakarta.*. This will almost certainly require code changes to enable applications to migrate from Tomcat 9 and earlier to Tomcat 10 and later. A migration tool is available to aid this process.$$$$$$The notable changes in this release are:$$$$$$Add strong ETag support for the WebDAV and default servlet; which can be enabled by using the useStrongETags init parameter with a value set to true. The ETag generated will be a SHA-1 checksum of the resource content.$$$Add support for RateLimit header fields for HTTP (RFC draft) in the RateLimitFilter. Based on pull request #775 provided by Chenjp.$$$Update Tomcats fork of Commons DBCP to 2.13.0.

Patch submitted by Michal Sobkiewicz.$$$Further WebDAV fixes and improvements.$$$Restore providing a value (rather than null) for Class.getProtectionDomain().getCodeSource().getLocation() as a number of libraries and JRE features depend on this being non-null even when a SecurityManager is not in use.$$$Full details of these changes; and all the other changes; are available in the Tomcat 11 changelog.
