Hey, I just tried updating from v1.4.0.beta6 +144 but the process failed, saying:
rake aborted!
Sass::SyntaxError: Undefined variable: “$primary” (in …common/admin/admin_vase.scss)
Now Discourse says there’s still an update but when I click it and go to the update screen it says it’s all update to date. I’m worried my install is in a bad state now, do I have to restore?
But, besides this, thanks for the great software it’s been working really well! 
Yes I can see this error, investigating at the moment.
thx for the speedy reply Sam!
Hi Sam,
How much more time you will take, and is there a way to rebuild my app without this commit?
Thanks.

Sorry about the drama, thanks for reporting.
