Introduced in 2021.1
We strive to maintain backward compatibility between versions so that you can upgrade seamlessly. However, sometimes we are forced to break compatibility, although we try to keep backward-incompatible changes to a minimum.
As part of your upgrade planning, see Upgrade considerations to view the backward-incompatible changes and other considerations you should be aware of, depending on which version you are upgrading from.
During the upgrade process, Alloy Navigator Express will show you a list of backward-incompatible changes for your version, along with that link to the documentation again, so you will have another chance to review them.
INFO: For a list of intermediate changes between versions and new functionality, see Release Notes.
