This is first stable release of E2Guardian V4.
Only required bug and security fixes will be applied in the v4.1.x point releases.
V4 is written in C++11 and uses threads, in order to make e2guardian scaleable to very large systems.
This version (v4.0 dev & v4.1 stable) is largely backward compatible with v3 configuration files.
Testing is showing an increase in speed and a big reduction in memory usage, as well as almost instant list reload with no interruption to service.
A big thanks to everyone who has contributed to getting this new release production-ready in such a short time.
Please see notes/NEWIN_v4 for details, and before trying to configure or compile.
