+* Deprecate `Reflection#source_macro`
+
+ `Reflection#source_macro` is no longer needed in Active Record
+ source so it has been deprecated. Code that used `source_macro`
+ was removed in #16353.
+
+ *Eileen M. Uchtitelle*, *Aaron Patterson*
+
* No verbose backtrace by db:drop when database does not exist.
Fixes #16295.
