Version 2.2.0 beta

Version 2.2 contains several new features and some bug-fixes (listed below). This post will be updated during the beta phase to let you know about the progress.

See Thonnys Bitbucket downloads page for download links.

Stepping back in time

One of the new features in 2.2 is possibility to step back in time during debugging. This comes in handy when you are debugging with big steps (step over) and accidentally step over an interesting part in code. Instead of starting from scratch again, you can now issue the command “Run -> Step back” which brings the visual represetation of the program back to the state as it was before last debugger command. From there you can choose to continue with small steps (step into). You can make as many steps back as required and you can go back and forward as many times as you wish.

Stepping back was implemented by Alar Leemet as part of his Bachelor thesis. Please give him feedback about this feature!
