10. Regressions
Regressions are documented only in the release in which they were introduced. For example, a regression introduced in 6.0.0 and fixed in 6.1.0 exists in both 6.0.0 and 6.0.1, but will only be listed in the 6.0.0 Regressions section. Each regression entry says in which release the regression was fixed.
Regressions fixed in 7.0.0, 7.1.0, or 7.2.0 are also fixed in 7.3.0, because 7.3.0 includes 7.0.0, 7.1.0, and 7.2.0.
Note
This Migration Guide focuses on the major, three-digit (LTS or feature) releases (6.0.1, 6.1.2, 7.3.0, etc.) in which a regression is introduced or fixed. Some regressions are also introduced or fixed in patch releases (such as 6.0.1.30), which are not mentioned in this Migration Guide. To find out if a regression is introduced or fixed in a patch release, contact RTI Support at support@rti.com or via the RTI Customer Portal (https://support.rti.com).
