Probably everyone saw that the public IE beta was released last week

It only runs on Vista or Windows 7, so XP users are out of luck.

I checked dojo, it is getting some failures in core and in dijit. Didn't
try anything in dojox/ but there are probably problems there too.

Not sure what we want to do about IE9... we need to support it for the
dojo 1.6 release, not sure if anyone wants to volunteer to backport the
support to dojo 1.5 or earlier (although I'm sure our users would
appreciate it).

As for upgrading dojo 1.6 to run on IE9, there are two time-saving
options (at least for core), if the FD branch gets finished soon:
1. wait for FD branch to be finished and merge into trunk
2. use tests in FD branch to tell us which dojo.isIE references should
be changed to dojo.isIE<9.

Other support options include:
3. change as many dojo.isIE references as possible to dojo.isIE<9
(theoretically IE is mostly standards compliant now)
4. only fix the stuff that's broke, leaving IE9 following the IE
specific code paths wherever they still work.

What do y'all think?

IMHO, IE9 is the opportunity for us to introduce FD => I'd prefer to
wait for dojo-fd to be ready. Another thing is: I am not sure we should
support it in 1.6 --- the actual release of IE9 is somewhere in 2011,
and they may have more betas out. If IE8 is any indication, the release
will screw us and our early support of the beta.

Having said that I'll work on the core to see what should be done. I
think that the rest (dijit and dojox) should wait for it to converge to
something stable.

Regarding backporting to 1.5 --- it is hard to tell now if it would
work. Ideally it should be your #4 option --- minimal changes to make
sure it works on IE9. But we have to see first how many "minimal
changes" we should do before committing to backporting to 1.5. If the
number is manageable we should do it. Otherwise we should stick to
supporting the final IE9 with whatever Dojo version we have at that time.
