 Revision history for Perl extension Class-MOP.
 
 0.90
+    Japan Perl Association has sponsored Goro Fuji to improve
+    startup performance of Class::MOP and Moose. These enhancements
+    may break backwards compatibility if you're doing (or using)
+    complex metaprogramming, so, as always, test your code!

     * Class::MOP::Class
     * XS
       - Anonymous classes were not destroyed properly when they went
         out of scope, leading to a memory leak. RT #47480 (Goro Fuji).
 
+    * Class::MOP::Class
+      - get_method, has_method, and add_method no longer use get_method_map.
+        Methods are more lazily instantiated to improve performance pretty
+        significantly (Goro Fuji)
+
+    * All classes
+      - Inline fewer metaclass-level constructors since the ones we have are
+        perfectly fine. This reduces the numbr of string evals (Goro Fuji)
