If you have upgraded from a very old version of Timeslips, it is sometimes difficult to find all the new features that have been added to Timeslips since your last upgrade. Even with the newer versions, it's not so easy to find everything that has changed in the new software.
Timeslips has provided all this information under the Help button. Just click on "Help", then select "What's New". You will then be presented with a list of hyperlinks to new features in every version since Version 9.1.
