can update by running:
hg pull
hg update release
Several package changes in this release may require you to update your code if
you use the bytes, template, or utf8 packages. In all cases, any outdated code
will fail to compile rather than behave erroneously.
The bytes package has changed. Its Add and AddByte functions have been removed,
as their functionality is provided by the recently-introduced built-in function
“append”. Any code that uses them will need to be changed:
s = bytes.Add(s, b) -> s = append(s, b...)
s = bytes.AddByte(b, c) -> s = append(s, b)
s = bytes.Add(nil, c) -> append([]byte(nil), c)
The template package has changed. Your code will need to be updated if it calls
the HTMLFormatter or StringFormatter functions, or implements its own formatter
functions. The function signature for formatter types has changed to:
func(wr io.Writer, formatter string, data ...interface{})
to allow multiple arguments to the formatter. No templates will need updating.
See the change for examples:
http://code.google.com/p/go/source/detail?r=2c2be793120e
The template change permits the implementation of multi-word variable
instantiation for formatters. Before one could say
{field}
or
{field|formatter}
Now one can also say
{field1 field2 field3}
or
{field1 field2 field3|formatter}
and the fields are passed as successive arguments to the formatter,
by analogy to fmt.Print.
The utf8 package has changed. The order of EncodeRune’s arguments has been
reversed to satisfy the convention of “destination first”.
Any code that uses EncodeRune will need to be updated.
Other changes:
* [68]l: correct dwarf location for globals and ranges for arrays.
* big: fix (*Rat) SetFrac64(a, b) when b < 0 (thanks Eoghan Sherry).
* compress/flate: fix typo in comment (thanks Mathieu Lonjaret).
* crypto/elliptic: use a Jacobian transform for better performance.
* doc/code.html: fix reference to "gomake build" (thanks Anschel
Schaffer-Cohen).
* doc/roadmap: update gdb status.
* doc/spec: fixed some omissions and type errors.
* doc: some typo fixes (thanks Peter Mundy).
* exp/eval: build fix for parser.ParseFile API change (thanks Anschel
Schaffer-Cohen).
* fmt: Scan accepts Inf and NaN,
allow "% X" as well as "% x".
* go/printer: preserve newlines in func parameter lists (thanks Jamie Gennis).
* http: consume request body before next request.
* log: ensure writes are atomic (thanks Roger Peppe).
* path: Windows support for Split (thanks Benny Siegert).
* runtime: fix SysFree to really free memory on Windows (thanks Alex Brainman),
parallel definitions in Go for all C structs.
* sort: avoid overflow in pivot calculation,
reduced stack depth to lg(n) in quickSort (thanks Stefan Nilsson).
* strconv: Atof on Infs and NaNs.
Apologies if we missed anyone in the list above. We appreciate all your help.

Yes. A failure on my part. Please s/02-12/12-02/ where appropriate.
The correct command to view the changes is:
hg log -r release.2010-11-23:release.2010-12-02
Apologies,
