+ - Issue #21991: Make email.headerregistry's header 'params' attributes
+   be read-only (MappingProxyType).  Previously the dictionary was modifiable
+   but a new one was created on each access of the attribute.
+ 
 +- Issue #22638: SSLv3 is now disabled throughout the standard library.
 +  It can still be enabled by instantiating a SSLContext manually.
 +
  - Issue #22641: In asyncio, the default SSL context for client connections
    is now created using ssl.create_default_context(), for stronger security.
