IntelliJ IDEA 11.1 will bring several changes with regard to VCS support and one of them is a number of enhancements in Perforce integration.
1. Handling Move
We used to handle rename/move operations using integrate. This was not quite convenient: for example, it made viewing history more difficult in external Perforce clients. Now that Perforce has a dedicated move command, we use it when possible. We hope this will save you some nerves and time.
2. Faster Changes Update
Another enhancement relates to Changes view refresh performance. In some cases refresh action took unfairly more time than necessary. Now it should be quicker.
3. Empty Changelists
And at last one more tricky improvement which may make your work with Perforce more transparent. After some operations a changelist might hover in pending state as empty but not visible in the IDE. Now IntelliJ IDEA does not hide such changelists to let you delete them. This also is quite useful since it keeps you from accumulation of empty changelists in Perforce.
All these changes are already available in the latest IntelliJ IDEA 11.1 EAP build.
