A beta version of the new release of Burp is now available to Professional users. Although this is a beta release it is highly stable and suitable for normal day-to-day use.
There are probably a few bugs to flush out, and I'll hopefully be adding a few more things during the beta period. Any feedback and bug reports would be much appreciated. Please email these directly so I can get back to you for more details if required.
Due to the phenomenal time sink that is the WAHH rewrite, this release will be in beta for at least a month. For users of the free edition who cannot wait that long, there is an easy solution.
Have fun!
