• A flow engine memory leak has been fixed;
• Unified2 would overwrite files if file rotation happened within a second of the file creation, leading to a loss of events/alerts;
• Flow manager mutex was uninitialized, but now it works properly;
• The windows building in CYGWIN was repaired.
There are also some problems with this release and the developer have acknowledged them. For example, there is talk about a possible IPv6 evasion, but since no details are available this hasn't been addressed yet.
