You modify items — that is, models, files, and tags — in the database by saving a commit on a branch. The set of changes in such a commit can be categorized as:

Commits involving the first category of changes have a direct correspondence with the table entries in The Versions Window — each version is saved in a commit. The latter two categories, which do not save new versions, only appear in The Commits Window.

You can provide an optional commit comment when saving a new commit. Oftentimes a comment describing the changes is already suggested. The comments can later be read and modified from The Commits Window or from The Versions Window. You can also find versions saved in a particular commit by applying a filter on the comment in the The Model Manager Window.
