The way the GroupManager exits has changed. If you have made changes and then close the GroupManager, you will now be asked if you want to apply the changes before it quits. It used to ask you if you wanted to quit. The various Run Program menus have been made less cluttered. A new icon has been created for the plugin eCheck.
Documentation is updated to reflect the changes.
Also a few mistakes in the documentation itself have been corrected. A few problems have been reported that have been impossible to reproduce. Some internal changes and fixes have however been done that might affect those problems. If you still have a problem, please report it again, with as much detail as possible. And remember to name the operating system you are running.
