Just came back from Snowboarding in Hintertux. Much fun.
Course the WP homepage is one of the first to visit. I installed the latest nightly and got the following error:
Database error: [Unknown column 'autoload' in 'where clause']
SELECT option_name, option_value FROM wp_options WHERE autoload = 'yes'
on re-running the upgrade.php script the error vanished.
more testing will follow…
