- no update
Add-on SDK (dtownsend)
App Tools (dtownsend)

Firefox Desktop (gavin)
- Australis reminder: This Nightly->Aurora merge is special. We'll be merging Holly to Aurora, rather than mozilla-central. Holly is mozilla-central minus Australis.
Firefox Metro (bbondy/jmathies/mbrubeck)

Firefox Mobile (mfinkle/blassey)
- Browsing is busted in nightly bug 945723 initial backouts for what we thought were the offending patches in bug 936756 did not fix the problem which isn't too surprising since we were super careful with the landing. Looks like something larger might be happening given bug 945750
- bug 709230 - (Proguard) Use ProGuard to shrink and optimize Fennec's Java .class files. Landed in Fx28 and is activated. Documentation should be available soon.

[2:11pm] catlee: nightlies [2:11pm] joduinn-mtg: gavin: followup about australis... can you make sure to loop hwine into the convo? he's on the hook for the migration with RelEng [2:12pm] gavin: joduinn-mtg: will do [2:12pm] • joduinn-mtg tips hat to gavin [2:12pm] gavin: catlee: I think you're probably in a better position to tell me? [2:12pm] gavin: I don't know [2:13pm] mbrubeck: gavin, catlee: The nightly-holly channel had 51 ADI yesterday [2:13pm] dveditz: gavin: is there any UI changes planned for the menus that slide into the customize panel? I like the Australis look over all, but that slidy menu thing is kinda ugly. Especially where it leaves part of the panel showing on the edge (looks like a mistake) [2:13pm] mbrubeck: laura: Sorry! Yes, you just missed the Platform meeting, if that's what you were asking [2:14pm] laura: no worries, I was absorbed in jcook's presentation [2:14pm] laura: and only realized the time when he finished [2:14pm] laura: thanks mbrubeck [2:14pm] mbrubeck: gavin, catlee: That's an increase of 5000% from last Wednesday, when it had 1 ADI! [2:15pm] catlee: we'll beat chrome in no time! [2:15pm] catlee: I'm a bit worried about shipping relatively untested builds to aurora users then [2:16pm] mschifer: we have been running automation on holly [2:16pm] gavin: dveditz: not sure what you're referring to - I see https://cloudup.com/c4GoZ7t9egv [2:16pm] mbrubeck: If we keep growing by 5000% every 5 days, then in another month we will have about 800 billion users on holly [2:17pm] gavin: dveditz: the "cut off icon on the left" styling is intentional - shows you how to get back to the normal panel [2:17pm] dveditz: gavin: exactly! notice the buttons half peeking on the left? looks like a mistake [2:18pm] gavin: it's a spatial orientation kind of thingy [2:18pm] dveditz: also felt a little odd to press the help button on the left of the panel and have the menu show up on the right [2:18pm] jesup: I think we missed a new contributor (first patch) in Friends of the Tree: Adrian Cruceru (email@example.com), bug 876876 which landed 11/22-23. [2:18pm] firebot: Bug https://bugzilla.mozilla.org/show_bug.cgi?id=876876 cri, --, mozilla28, cruceru.adrian, VERI FIXED, crash in webrtc::videocapturemodule::DeviceInfoDS::GetDeviceInfo [2:18pm] dveditz: gavin: I get that it's intentional... I'm just saying it doesn't really work for me (one isolated anecdotal data point, from an otherwise Australis fan not a hater) [2:19pm] gavin: ok! [2:19pm] dveditz: just throw it in the bucket of feedback for later [2:19pm] dveditz: and see if more like it pile up or I'm an outlier [2:19pm] mbrubeck: Maybe if the "peeking" part on the left were faded somewhat it would look more intentional. [2:20pm] gavin: shorlander: ^ [2:25pm] mbrubeck: (or dimmed?) [2:26pm] shorlander: mbrubeck: History in the panel here might be more inline with what you are talking about: http://people.mozilla.org/~shorlander/mockups-interactive/australis-interactive-mockups/windows8.html [2:26pm] shorlander: gavin, dveditz: thanks!
