Subject: Understanding versioning of a .cui file

Each .cui file has a node that controls versioning:

<FileVersion MajorVersion="1" MinorVersion="2" UserVersion="0" IncrementalVersion="91"/>

   IncrementalVersion Must be incremented with any change in the Icad.cui file.

   UserVersion Incremented automatically when a user customizes CADdirect. In the default Icad.cui file, this must be always equal to 0 and never edited manually.

   MinorVersion Must be incremented with a change or creation of a versioned entity (PopMenu, Toolbar, MenuMacro->Macro, ...).

   MajorVersion Must be incremented with the following:

   Change of Icad.cui file schema (for example, added/deleted sections or added new type of entities).

   Deletion of a versioned entity.

   Change of UID attribute of an existing versioned entity or change of Name attribute in case of a Workspace entity.

If MajorVersion is incremented, the user's .cui file will be replaced with an updated .cui file.

The .cui file also contains versioned entities: Workspace, MenuMacro->Macro, Pop­Menu, Toolbar, AppButton, QuickAccessToolbar, RibbonPanelSource, and
RibbonTabSource. Each versioned entity also has a node:

<ModifiedRev MinorVersion="2"/>

After a versioned entity is modified or created, FileVersion->MinorVersion must be incremented, and then the result must be assigned to ModifiedRev->MinorVersion of the modified entity.
