 Changes with Apache 2.4.19
 
+  *) mod_http2: slave connections are reused for several requests, improved
+     performance and better memory use. [Stefan Eissing]
+     
   *) mod_rewrite: Don't implicitly URL-escape the original query string
      when no substitution has changed it (like PR50447 but server context)
      [Evgeny Kotkov <evgeny.kotkov visualsvn.com>]
