At the time of writing Firefox was updated to 130.0 by me 9 hours ago on unstable.
Updates are not always Friday/Saturday because sometimes we defer updates but as a general rule yes, that is when you get updates. We also cherry-pick updates to stable whenever we need.
brent just curious, what's on Mastadon that I don't get here? Is it a little more real-time, 'you heard it here first' type stuff?
Nothing really, its 99% links to the weekly sync thread or announcing a blog post. Kinda like our subreddit.
