+This weekly snapshot renamed the html package to exp/html. The package will not
+be present in the Go 1 distribution, but will be installable from source.
+
+Error variables in the archive/tar, archive/zip, compress/gzip, compress/zlib,
+and crypto/bcrypt packages have been renamed from FooError to ErrFoo. 
+There is no gofix, but the compiler will flag code that needs updating.
+
+Other changes:
+* 6c, 8c: make floating point code NaN-safe.
+* 6l, 8l: remove unused macro definition (thanks Shenghou Ma).
+* archive/tar: fix race in TestNonSeekable.
+* archive/zip: add functions to convert between os.FileInfo & FileHeader.
+* build: do not build all C compilers (thanks Shenghou Ma),
+	remove code now in subrepositories.
+* bytes: remove dead code, complete documentation,
+	restore panic on out-of-memory,
+	turn buffer size overflows into errors.

+	use append instead of slice+counter.
+* crypto: rename some FooError to ErrFoo.
+* dashboard: fix -commit for new xml package.
+* database/sql: add NullInt64, NullFloat64, NullBool (thanks James P. Cooper),
+	convert SQL null values to []byte as nil (thanks James P. Cooper),
