At any point in time, all IDEs run on the same version of the software. However, Acquia cannot carry through a few updates to existing IDEs. For example, Acquia might not be able to properly apply the updates to .bashrc if you have have customized it greatly.

Therefore, Acquia continues to recommend customers to view Cloud IDE as a disposable resource that can be destroyed and recreated at will. To leverage the latest and greatest IDE software, ensure that you periodically recreate your IDE. Acquia recommends you to recreate your IDE once per quarter.
