I'll try to find some time during the day to look at the RB issues.
Hopefully we can get Guido to look at them too and Pronounce on some
of them. Guido please start with:

My plan is to begin building the betas tonight, at around 9 or 10pm
EDT (0100 to 0200 UTC Thursday). If a showstopper comes up before
then, I'll email the list. If you think we really aren't ready for
beta, then I would still like to get a release out today. In that
case, we'll call it alpha and delay the betas.
There are two things I'd like to get in to 3.0:
* .transform()/.untransform() methods (this is mostly done, just need
to add the methods to PyUnicode, PyBytes and PyByteArray)
What would these methods do? Use the codec machinery without any type
checks?
As discussed in another thread some weeks ago:
.transform() and .untransform() use the codecs to apply same-type
conversions. They do apply type checks to make sure that the
codec does indeed return the same type.
E.g. text.transform('xml-escape') or data.transform('base64').
So what would a base64 codec do with the errors argument?
I think for transformations we don't need the full codec machinery:

No need to invent another wheel :-) The codecs already exist for
Py2.x and can be used by the .encode()/.decode() methods in Py2.x
(where no type checks occur).
By using a new API we could get rid of old warts. For example: Why does
the stateless encoder/decoder return how many input characters/bytes it
has consumed? It must consume *all* bytes anyway!
In Py3.x, .encode()/.decode() only allow conversions of the type
unicode <-> bytes. .transform()/.untransform() add conversions
of the type unicode <-> unicode or bytes <-> bytes.
All other conversions in Py3.x have to go through codecs.encode() and
codecs.decode() which are the generic codec access functions from
the codec registry.
Servus,
Walter
