Update don't apply
Can't get no (satisfaction) update on my test site(s)
To test it even more better, I did the next:
1. Clean installation of RC3, no mods (only those coming with installation), no changes, jast outta boks - check.
2. Cron job - as described in installation - check.
3. Server audit all-green - check.
4. Nice red announcement about RC4 in Dash & Update button - check.
5. Long time (I mean LONG TIME) showing "Site will be upgraded within a minute" and no update - check.
