The third release candidate is available for download at
http://www.itmill.com/download/itmill-toolkit/unstable/5.3.0/rc3/
.
This is again a preliminary release candidate that still has a number of known problems that have to be solved before release. This RC includes a few more solved problems. It may be that we are going to get at least a few of these before the actual release.
