    * Fix: Avoid NPE in RewriteValve. (markt)
    * Fix: 70127: Fix use of Bootstrap through reflection by restoring the public constructor. Use
through scripts was not affected. (remm)
    * Fix: Restore ability to extend many element classes from AbstractAccessLogValve. (remm)
    * Fix: Align DIGEST authentication with RFC 7616 and require clients to provide a valid qop
parameter. (markt)
    * Fix: Use Files API to create temporary docBase when antiLockingDocBase is enabled. (markt)
    * Fix: Improve validation of configuration when DataSourceRealm starts. (remm)

RewriteValve. (markt)

the connector is explicitly configured to use Tomcat Native with OpenSSL for TLS. (markt)
    * Fix: Correct a regression introduced in 9.0.119 that broke reading of some request bodies via
a Reader. (markt)

This fix prevents tags from being re-used if such an exception occurs. (markt)
    * Fix: 70135: Fix security classload regression. (remm)
    * Add: support for specifying Java 28 (with the value 28) as the compiler source and/or

support these values, a warning will be logged and the default will be used. (markt)
