# CHANGELOG
-----
+## `v9.0.0-beta`
+### ARM
+In addition to the tabulated changes below, each package had the following updates:
+ - API Version is now associated with individual methods, instead of the client. This was done to
+ support composite swaggers, which logically may contain more than one API Version.
+ - Version numbers are now calculated in the generator instead of at runtime. This keeps us from
+ adding new allocations, while removing the race-conditions that were added.
