 ### Platforms
 
-Only the last 4 major platform versions are supported, starting from:
-
-- iOS **12**
-- macOS **10.15**
-- macCatalyst **13**
-- tvOS **12**
-- watchOS **6.2**
-
 Once a platform version becomes unsupported, dropping it from Auth0.swift **will not be considered a breaking change**, and will be done in a **minor** release. For example, iOS 13 will cease to be supported when iOS 17 gets released, and Auth0.swift will be able to drop it in a minor release.
 
 In the case of macOS, the yearly named releases are considered a major platform version for the purposes of this Policy, regardless of the actual version numbers.
