This is a new major release of the ACT FFXIV plugin, as part of a refactoring push. The network data reading routines have been rewritten from the ground up, and externalized in the Machina library: https://github.com/ravahn/machina
This resolved a few hard-to-find TCP/IP and FFXIV stream decoding bugs, which should make parses slightly more correct and comparable between players. I also paid special attention to memory allocation for the network routines, which should improve CPU usage. In order to use the Machina library, a .net library called Fody.Costura was used to embed it inside the FFXIV_ACT_Plugin.dll.
This version is intended to be fully compatible with FFLogs, and most ACT plugins should not have any problems with it since the changes were primarily to the network data retrieval routines, which most DLLs do not access.
