-Replaces `toString(int256)` with `toStringSigned(int256)`
-
-# WHAT the breaking change is?
-
-- The toString(int256) is now replaced with toStringSigned(int256)
-
-# WHY the change was made?
-
-- The change was made as invoking `toString(int256)` with an integer literal from another contract was failing with the error `Member "toString" not unique` since `toString(1)` qualifies for both int256 & uint256, hence replaced `toString(int256)` with `toStringSigned(int256)`.
-
-# HOW a consumer should update their code?
-
-- Replace the instances of `toString(int256)` with `toStringSigned(int256)`.
+`Strings`: Rename `toString(int256)` to `toStringSigned(int256)`.
