Gecko 1.9 Alpha Planning

From MozillaWiki
Jump to: navigation, search

Much of this page has been merged into Firefox3/Gecko Feature List.

At the 4/20/2006 dev.platform/content meeting we discussed the idea of shooting for early June to get a set of builds together for widepread testing and feedback on the current state of the trunk. We will need more work on the blocking bug lists, more updates on the landing plan, and some more feedback accross the project to see if the early June stake in the ground makes sense.

Getting to a widespread Alpha testing release involves:

  • assembling some level of features that would be interesting to get testing feeback on,
  • getting builds that are stable, usable, regression proof, and in good enough shape that they can be used long enough to get good depth and breath testing. Any bugs that would block this kind of usage need to be dealt with.

Bug Lists

Links to Alpha blocker nominations and approvals that would get us to a set of usable builds are provided here:

Feature Decisions

This need discussion, review, and decisions.

Status of feature landings:

The table below has the large features that either have already landed in Gecko 1.9 or are planned to land. The list may not be complete; please add as needed if you're working on something or planning to. The list should primarily include architecture changes that are either considered blockers for 1.9 or have significant regression risk (or both). may have inspiration for things to include (assuming they're actually being worked on or planned). Please do NOT add pure wishlist items to the list -- if it's not being worked on or seriously planned, it shouldn't be here.
