7. Regressions

Regressions are documented in the release in which they were introduced, as well as the releases to which they still apply. For example, a regression introduced in 6.0.0 and not fixed until 6.1.0 will be listed in both the 6.0.0 Regressions and 6.0.1 Regressions sections below.

Regressions fixed in 7.0.0, 7.1.0, or 7.2.0 are also fixed in 7.3.0, which includes these 7.x releases.

Note

This Migration Guide focuses only 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. Many regressions are also fixed in patch releases (such as 6.0.1.30), which are not always mentioned in this Migration Guide. To find out if a regression is fixed in a patch release, contact RTI Support at support@rti.com or via the RTI Customer Portal (https://support.rti.com).
