Drop compat code for IOContext ctor taking pairs from #427

README.md

@@ -88,8 +88,6 @@ Currently, the `@compat` macro supports the following syntaxes:
 * `@compat finalizer(func, obj)` with the finalizer to run as the first argument and the object to be finalized
   as the second ([#24605]).
 
-* `IOContext` accepting key-value `Pair`s ([#23271]).
-
 * `get` do-block syntax supported when using `ENV` ([#23412]).
 
 * `Some{T}` wraps `T` to signify that a result of `T<:Void` is expected ([#23642]).
