The cross-version compatibility checking mechanism is triggered when a project with new feature usages is loaded with an older version of the modeling tool. The mechanism tracks feature usages of 19.0 SP2, 19.0 SP3, and later service pack (SP) versions that result in the appearance of a Missing features detected notification in earlier modeling tool versions. The following table shows tracked features, the version they appear in, and whether the project can be committed/saved without any consequences.
| Feature name | Version | Secure to commit/save |
|---|---|---|
| 19.0 SP2 | Yes | |
| Contextual relationships in the dependency matrix | 19.0 SP3 | Yes |
| Displaying classifiers on internal structure and behavior diagrams | 19.0 SP3 | Yes |
| Custom hierarchy in tables | 19.0 SP3 | Yes |
| Lock-free Model Editing | 19.0 SP3 | No |
If you are working with features that can cause inconsistencies after save/commit (see the table above), the following warning message indicating possible consequences if you proceed will be shown.
