The code name for this release is “SPEED BOOST” as it brings 2x speed increase for backtest and optimizations. This is the result of many days of code profiling and tweaks. The result is achieving dual-core performance on old computers (no hardware update necessary) :-)

There is also new Code Profiler available from AFL Editor, Tools->Code Check & Profile, that shows detailed report on how many times each function is called and how much time it takes to execute.

Remember that this is a BETA software. So BACKUP YOUR FILES FIRST ! Note that you need to install official version 5.00 prior to installing this beta
