 ## Deprecation
 
-For approximately 3 months after a _major_ release, the _major_ release preceding it will be supported. After 3 months, the previous _major_ release is deprecated and will no longer be supported.
-
-Support of a _major_ version entails the following:
-
-- SVGs and metadata of brands will be updated on request. This excludes brands that were removed in the new _major_ release.
-- Bugs in the npm library will be updated if reported.
+After a _major_ release, the only other supported version is the last version of the previous _major_ release. This previous version will only receive bug fixes to either the npm library, or our internal APIs.
