     sections. [Stefan Fritsch]

     with LogLevel trace7 or trace8.  PR 53730.  [Rainer Jung]

     possible XSS for a site where untrusted users can upload files to

     current group. PR 52464 [Eric Covener]
  *) mod_lua: Add new directive LuaAuthzProvider to allow implementing an
     authorization provider in lua. [Stefan Fritsch]

  *) core: Be less strict when checking whether Content-Type is set to 
     "application/x-www-form-urlencoded" when parsing POST data, 
     or we risk losing data with an appended charset. PR 53698
     [Petter Berntsen <petterb gmail.com>]

  *) httpd.conf: Added configuration directives to set a bad_DNT environment
     variable based on User-Agent and to remove the DNT header field from
     incoming requests when a match occurs. This currently has the effect of
     removing DNT from requests by MSIE 10.0 because it deliberately violates
     the current specification of DNT semantics for HTTP. [Roy T. Fielding]

  *) mod_socache_shmcb: Fix bus error due to a misalignment
