Currently we can use 2.065 and 2.066 in http://asm.dlang.org. We should have the option of using the current (prerelease) version of the compiler fetched straight from github. tools/update.sh contains all we need. We just have to put that in a cron job and hook the binaries into the front-end appropriately. Iain has his hands full with more urgent tasks. If there are any takers I'd be glad to set you up with a ssh account to get this done.
I'll take it.
Looking forward to it!
asm.dlang.org now has a "DMD (nightly build)" option, I guess this is fixed?
