  Fixes having an issue number are sorted by their number, ascending.

  There is no ordering by add/update/fix.

  Other fixed issues are added to the end of the list, chronologically.
  They eventually become mixed with the numbered issues. (I.e., numbered

    <changelog>
      <add>
        <bug>59961</bug>: Add an option to the <code>StandardJarScanner</code>
        to control whether or not JAR Manifests are scanned for additional
        class path entries. (markt)
      </add>
      <fix>
        <bug>60013</bug>: Refactor the previous fix to align the behaviour of
        the Rewrite Valve with mod_rewite. As part of this, provide an
        implementation for the <code>B</code> and <code>NE</code> flags and
        improve the handling for the <code>QSA</code> flag. Includes multiple
        test cases by Santhana Preethiand a patch by Tiago Oliveira. (markt)
      </fix>
      <fix>
        <bug>60087</bug>: Refactor the web resources handling to use the Tomcat
        specific <code>war:file:...</code> URL protocol to refer to WAR files
        and their contents rather than the standard <code>jar:file:...</code>
        form since some components of the JRE, such as JAR verification, give
        unexpected results when the standard form is used. A side-effect of the
        refactoring is that when using packed WARs, it is now possible to
        reference a WAR and/or specific JARs within a WAR in the security policy
        file used when running under a <code>SecurityManager</code>. (markt)
      </fix>
      <fix>
        <bug>60116</bug>: Fix a problem with the rewrite valve that caused back
        references evaluated in conditions to be forced to lower case when using
        the <code>NC</code> flag. (markt)

        unknown type or specifies the wrong type. (markt)

      <fix>
        <bug>60167</bug>: Ignore empty lines in <code>/etc/passwd</code> files
        when using the <code>PasswdUserDatabase</code>. (markt)
      </fix>
      <fix>
        <bug>60170</bug>: Exclude the compressed test file
        <code>index.html.br</code> from RAT analysis. Patch provided by Gavin
        McDonald. (markt)

        When starting web resources, ensure that class resources are only
        started once. (markt)

      <fix>
        Improve the access checks for linked global resources to handle the case
        where the current class loader is a child of the web application class
        loader. (markt)

      <fix>
        Correctly handle a call to <code>AsyncContext.complete()</code> from a
        non-container thread when non-blocking I/O is being used. (markt)
      </fix>
      <add>
        Refactor the code that implements the requirement that a call to
        <code>complete()</code> or <code>dispatch()</code> made from a
        non-container thread before the container initiated thread that called
        <code>startAsync()</code> completes must be delayed until the container
        initiated thread has completed. Rather than implementing this by
        blocking the non-container thread, extend the internal state machine to
        track this. This removes the possibility that blocking the non-container
        thread could trigger a deadlock. (markt)

        Provide a mechanism that enables the container to check if a component

        generate the absolute URI for the redirect. With the fix for

        to the last modified time of the WAR. If Tomcat detects a modified WAR
        via this mechanism the web application will be redeployed (i.e. the
