On the trunk:

mod_md: v0.9.5:
     - New directive (srly: what do you expect at this point?) "MDMustStaple on|off" to control if
       new certificates are requested with the OCSP Must Staple extension.
     - Known limitation: when the server is configured to ditch and restart child processes, for example
       after a certain number of connections/requests, the mod_md watchdog instance might migrate 
       to a new child process. Since not all its state is persisted, some messsages might appear a
       second time in the logs.
     - Adding checks when 'MDRequireHttps' is used. It is considered an error when 'MDPortMap 443:-'
       is used - which negates that a https: port exists. Also, a warning is logged if no 
       VirtualHost can be found for a Managed Domain that has port 443 (or the mapped one) in
       its address list.
     - New directive 'MDRequireHttps' for redirecting http: traffic to a Managed Domain, permanently
       or temporarily.
     - Fix for using a fallback certificate on initial signup of a Managed Domain. Requires also
       a changed mod_ssl patch (v5) to take effect.
     - compatibility with libressl
