+* When a task forks a child, the parent task's task-local RNG (random number generator) is no longer affected. The seeding of child based on the parent task also takes a more disciplined approach to collision resistance, using a design based on the SplitMix and DotMix splittable RNG schemes ([#49110]).
+* A new morespecific rule for methods resolves ambiguities containing Union{} in favor of
+  the method defined explicitly to handle the Union{} argument. This makes it possible to
+  define methods to explicitly handle Union{} without the ambiguities that commonly would
+  result previously. This also lets the runtime optimize certain method lookups in a way
+  that significantly improves load and inference times for heavily overloaded methods that
+  dispatch on Types (such as traits and constructors).
+* The "h bar" `ℏ` (`\hslash` U+210F) character is now treated as equivalent to `ħ` (`\hbar` U+0127).
