On Linux, it is mostly fixed to use wx3.0; on Windows, it is NOT really being tested with anything except wx2.8.12 in building Code::Blocks. Edit: The building of Code::Blocks using wx3.0 works great; but, the running of that binary has NOT been tested a lot; but, it might work great. Since there has been a lot of Linux wx3.0 fixes since I last tried it.
