Subject: Added Jim Weirich's excellent FlexMock class to vendor (Copyright
 2003, 2004 by Jim Weirich (jim@weriichhouse.org)) -- it's not automatically
 required, though, so require 'flexmock' is still necessary [DHH]

+* Added Jim Weirich's excellent FlexMock class to vendor (Copyright 2003, 2004 by Jim Weirich (jim@weriichhouse.org)) -- it's not automatically required, though, so require 'flexmock' is still necessary [DHH]
+
 * Fixed that Module#alias_method_chain should work with both foo? foo! and foo at the same time #4954 [anna@wota.jp]
 
 * to_xml fixes, features, and speedup: introduce :dasherize option that converts updated_at to updated-at if true (the existing default); binary columns get encoding="base64" attribute; nil values get nil="true" attribute to distinguish empty values; add type information for float columns; allow arbitrarily deep :include; include SQL type information as the type attribute.  #4989 [Blair Zajac <blair@orcaware.com>]
