Been a while since I've written and released a tool, but PSA3 was so stuffed with bugs and lacked a Local File Inclusion feature that lots of people began asking for fixes. You can read all about PSA3 here. PSA4 will mainly do the same but with a lot less bugs, the freezing has been fixed completely for example. The second most asked feature 'LFI recognition' has been added but needs tweaking at the moment. The SQL injection regex has been updated but this will not mean more SQL injection results. I'm sorry for the disappointment, that this release will still contain lots and lots of inefficient coding, like the previous version did, but the code has become so big I just can't be bothered rewriting it all. The GUI itself hasn't changed much, the file counter made place for a percent counter and there is also a counter for 'total lines scanned' to give an impression of the scan speed.
