hey, yeah this release is pretty big, we have a new platform and are dropping the default IDE in one of the supported platforms, codeblocks to substitue it with qtcreator. usually when we release an RC there's some fixes to do and in a couple of weeks we have fixed everything that appears but in this case we had some more issues.
there's also some work going on with a new version of the project generator but there will be an RC2 next week surely and right after that the release since the current code seems to be already pretty stable
