  *) event: Use skiplist data structure. [Jim Jagielski]
  *) event: Fail at startup with message AP02405 if the APR atomic
     implementation is not compatible with the MPM.  [Jim Jagielski]

  *) mpm_unix: Add ap_mpm_podx_* implementation to avoid code duplication
     and align w/ trunk. [Jim Jagielski]

  *) Fix potential rejection of valid MaxMemFree and ThreadStackSize
     directives.  [Mike Rumph <mike.rumph oracle.com>]

  *) mod_proxy_fcgi: Remove 64K limit on encoded length of all envvars.

  *) mod_proxy_fcgi: Handle reading protocol data that is split between
     packets.  [Jeff Trawick]

  *) mod_ssl: Improve handling of ephemeral DH and ECDH keys by

     Unless custom parameters are configured, the standardized parameters
     are applied based on the certificate's RSA/DSA key size. [Kaspar Brand]

  *) mod_ssl, configure: Require OpenSSL 0.9.8a or later. [Kaspar Brand]

  *) mod_ssl: drop support for export-grade ciphers with ephemeral RSA
     keys, and unconditionally disable aNULL, eNULL and EXP ciphers

     backend server endpoint [Jim Jagielski, Blaise Tarr
     <blaise tarr gmail com>]

  *) Add experimental cmake-based build system for Windows.  [Jeff Trawick,

     or occasional missed mod_status updates for some keepalive requests 
     under load. [Eric Covener]

     socache providers.  [Chris Darroch]

     [Graham Leggett]

  *) mod_headers: Allow for format specifiers in the substitution string
     when using Header edit. [Daniel Ruggeri]

  *) core: Don't truncate output when sending is interrupted by a signal,
     such as from an exiting CGI process. PR 55643. [Jeff Trawick]

  *) WinNT MPM: Exit the child if the parent process crashes or is terminated.
     [Oracle Corporation]

     they occured. [Christophe Jaillet]

     PR54948 [Eric Covener]

  *) mod_auth_basic: Add AuthBasicUseDigestAlgorithm directive to
     allow migration of passwords from digest to basic authentication.
     [Chris Darroch]

     headers value into a note. [Eric Covener]

  *) mod_logio: new format-specifier %S (sum) which is the sum of received
     and sent byte counts.
     PR54015 [Christophe Jaillet]

  *) mod_deflate: Improve error detection when decompressing request bodies
     with trailing garbage: handle case where trailing bytes are in
     the same bucket. [Rainer Jung]

  *) mod_authz_groupfile, mod_authz_user: Reduce severity of AH01671 and AH01663
     from ERROR to DEBUG, since these modules do not know what mod_authz_core
     is doing with their AUTHZ_DENIED return value. [Eric Covener]

  *) mod_ldap: add TRACE5 for LDAP retries. [Eric Covener]

  *) mod_ldap: retry on an LDAP timeout during authn. [Eric Covener]

       - Save a few cycles

  *) mod_filter: Add "change=no" as a proto-flag to FilterProtocol
     to remove a providers initial flags set at registration time.
