They include:
- Reset all testcases with success/failure/relative/not_executed status. On pressing the Submit button a dialog pops up and asks if it is needed to clear all the comments as well
- List & open the attachments for tests and test cases
- List & edit bugs (integrated, generic, mantis, bugzilla, jira trac) associated to tests
- Auto-submission of the comments on focus lost (at least ! :)). In addition, it's now easy to identify the comments being edited (not yet submitted) and those already submitted
- Edit/delete tests
- Edit/delete test case
What will have to wait for sure for 1.6:
- Create new test
- Create new test case
