-- Update to version 1.50.2+20180106.b3e0002:
-  + object:
-    - Only reset keep-alive and disassociate if needed.
-    - Make clear in toString() proto method when the object is
-      finalized.
-    - Show error when using proto functions (connect*, emit) on
-      destroyed object.
-    - Only show critical errors on access to finalized objects.
-    - Remove ObjectInstance from disassociate_list if object is
-      finalized.
-    - Leave out param untouched on error.
-    - Reset the keep alive flag on wrapper when object is disposed.
-    - Add better logging when invalid access happens.
-    - Don't resolve or set,get properties on finalized elements.
-  + installed-tests/js: add testGObjectDestructionAccess to verify
-    access to destryed objects.
-- Switch to git-checkout via source service. Following this, add
-  autoconf-archive and libtool BuildRequires and pass autogen.sh to
-  bootstrap the tarball.
-- Cleanup spec, use modern macros, autosetup and make_build.
