We keep latest release in each branch available for download any time.
Remember to install .zip & .tar.gz versions into COMPLETELY EMPTY FOLDER. Do not just unpack over previous version!
Your non-bundled plugins probably will break when changing between branches! You'll need to get the correct version (it may be inexistent)
Remember to BACKUP your SETTINGS before 1st run when changing your build UP (the ~/WebIde* folders in you home dir + .idea folder in each project)
You'll need BACKUP and ERASE your SETTINGS 1st before run when changing your build DOWN (the ~/WebIde* folders in you home dir + .idea folder in each project)
