+
+This weekly snapshot includes major changes to the reflect package and the
+os.Open function. Code that uses reflect or os.Open will require updating,
+which can be done mechanically using the gofix tool.
+
+The reflect package's Type and Value types have changed. Type is now an
+interface that implements all the possible type methods. Instead of a type
+switch on a reflect.Type t, switch on t.Kind(). Value is now a struct value
+that implements all the possible value methods. Instead of a type switch on a
+reflect.Value v, switch on v.Kind(). See the change for the full details:
+ http://code.google.com/p/go/source/detail?r=843855f3c026
+
+The os package's Open function has been replaced by three functions:
+ OpenFile(name, flag, perm) // same as old Open
+ Open(name) // same as old Open(name, O_RDONLY, 0)
+ Create(name) // same as old Open(name, O_RDWR|O_TRUNC|O_CREAT, 0666)
+
+To update your code to use the new APIs, run "gofix path/to/code". Gofix can’t
+handle all situations perfectly, so read and test the changes it makes before
+committing them.
