We're coming up fast on the 1.8 Beta freeze -- February 9. When we ship Beta, we'll be locking down the trunk until we branch for Gecko 1.8. See the roadmap diagram for more detailed schedule information.
Beta is the last chance to get L10N impact changes landed for all of our applications. It's also the last chance to get any high-risk or potentially destabilizing changes landed. With the Firefox and Thunderbird 1.1 "Gecko update" releases scheduled to come from that branch, we can't afford to regress stability over the 1.7 and Aviary 1.0 branches.
Ben has posted some information on the 1.1 release at his weblog and I hope to have an updated Aviary roadmap graphic soon.
