Pion 4.0.7 is now available.
In addition to the usual roundup of bug fixes, this release includes a few notable new features:
- Pion Replay now allows you to define multiple criteria when performing a search for matching visitor sessions. This feature has a known regression in that you cannot specify multiple criteria for the same vocabulary term (for example status code is greater than 399 AND status code is less than 500). We're working a fix but since it's non-trivial will not likely include it in 4.0.
- The Google Analytics Reactor now includes support for Google's new Site Speed Analytics Report. Now you can get accurate page load measurements without having to use page tags!
- The DatabaseOutput Reactor now automatically attempts to reconnect when it loses a connection and allows you to use multiple threads to perform bulk inserts concurrently.
Here is a complete list of changes since 4.0.5, along with the related trac tickets:
- Replay - support multiple search criteria for finding sessions (953, 973)
- Replay - added configuration options for base-href behavior (1168)
- SnifferReactor - support multiple SSL keys using same IP & port (1162)
- ClickstreamReactor - refuse configuration with duplicate host suffixes (1165)
- Google Analytics - added support for the new page-load speed feature (1161)
- HTTPProtocol - fixed rare segmentation fault when content is truncated (1166)
- HTTPProtocol - enforce that request and response content is UTF-8 (1160)
- Database Output Reactor - multiple threads for concurrent bulk inserts (1159)
- Database Output Reactor - automatically recover from lost connections (1167)
- Event string terms now automatically ensure that content is UTF-8 (1158)
- Fixed pget --addkey server timeout regression (1163)
- Fixed pget --removekey error reporting failures (1164)
