 ## Release Overview
 
-- 
+The 1.1 release of Design Builder mostly includes performance improvements in the implementation system. There is a breaking change related to one-to-one relationships. Prior to the 1.1 release, one-to-one relationships were not saved until after the parent object was saved. The performance optimization work revealed this as a performance issue and now one-to-one relationships are treated as simple foreign keys. Since foreign key saves are not deferred by default, it may now be necessary to explicitly specify deferring the save operation. A new `deferred` attribute has been introduced that causes design builder to defer saving the foreign-key relationship until after the parent object has been saved. The one known case that is affected by this change is when setting a device primary IP when the IP itself is created as a member of an interface in the same device block. See unit tests and design examples for further explanation.
 
-## [v1.6.0] - 2023-09
+Additionally, the `design.Builder` class has been renamed to `design.Environment` to better reflect what that class does. A `Builder` alias has been added to `Environment` for backwards compatibility with a deprecation warning.
