How does versioning work?
Managing versions can be complicated. We have tried to make this
as painless as possible. Every time you make a change in your
flatplan a new version is automatically created.
Flatplan limits the number of versions it can keep track of to 50.
When you have made more than 50 changes Flatplan will start to
forget the oldest changes in order to keep track of the new.
Click on the "History-button".

Drag the slider view a older version.

Note: You can't edit a old version of a flatplan without promoting it to the current version.
If you want to make a old version the working copy and make it editable click the "Make current" button.
