- On-demand access to sumstats results through "return from" functions named SumStats::request and Sumstats::request_key. Both functions are tested in standalone and clustered modes. - $name field has returned to SumStats which simplifies cluster code and makes the on-demand access stuff possible. - Clustered results can only be collected for 1 minute from their time of creation now instead of time of last read. - Thresholds use doubles instead of counts everywhere now. - Calculation dependency resolution occurs at start up time now instead of doing it at observation time which provide a minor cpu performance improvement. A new plugin registration mechanism was created to support this change. - AppStats now has a minimal doc string and is broken into hook-based plugins. - AppStats and traceroute detection added to local.bro
