- OnClick - Event when you click on TfrMemoView in playback mode built reports
- OnMouseEnter - Event at the Enter of the mouse over TfrMemoView in playback mode built reports
- OnMouseLeave - Event at the Leave of the mouse TfrMemoView in playback mode built reports
- The object TfrMemoView added new properties
- Cursor - the mouse cursor when moving over TfrMemoView in playback mode built reports
- DetailReport - a reference to the detail-report - called when the user clicks the mouse on TfrMemoView in playback mode built reports
- A mechanism to detail-report - call a detailed report of the current report
- In ineterpretatore added new features (for compatibility with FastReport 2.5):
