  New Revision: 63300

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=63300

  Log:
    Remove the teeny part from the shared library name on macOS
    
    This will prevent macOS users from having to rebuild all extension
    libraries every time they upgrade ruby to a new teeny release.
    
    Before:
    - libruby.2.6.0.dylib
    - libruby.2.6.dylib -> libruby.2.6.0.dylib
    - libruby.dylib -> libruby.2.6.0.dylib
    
    After:
    - libruby.2.6.dylib
    - libruby.dylib -> libruby.2.6.dylib

 * VM generator script renewal; makes the generated VM more optimized. [GH-1779]
 
 === Miscellaneous changes
+
+* On macOS, shared libraries no longer include a full version number of ruby in their names.
+  This eliminates the burden of each teeny upgrade on the platform that users need to rebuild every extension library.
