4.1.2 in AOSP

[Jean-Baptiste Queru]

We're releasing Android 4.1.2 to AOSP today, which is a minor update
on top of 4.1.1.

As a note to maintainers of community builds running on Nexus 7:
please update to 4.1.2 at the first opportunity. Future variants of
the grouper hardware will have a minor change in one of the components
(the power management chip) that will not be compatible with 4.1.1.

The build number is JZO54K, and the tag is android-4.1.2_r1.

Enjoy,
Conley and JBQ

Does this mean we will see a new factory image for Grouper soon?

Availability of factory images will match the timing of the OTA to
retail devices, as usual.

This release contains the full git logs, as usual.

I can't talk about future releases, sorry.

I'm sure someone will gather a full changelog from git once all the
replication completes.

The new chip is functionally identical to the old one, but requires
some bootloader and driver tweaks. You don't gain anything from it (if
anything, you lose the ability to run 4.1.1).

No, there's no specific time frame for future releases.

I haven't been able to follow the exact change-by-change log of what
went into this release.

That is not, and has never been, something that the people on this list can provide an answer to.

Soon. Typically, the end-to-end process for a push takes a bit more
than 1 hour, more if that's a complex release.

I'll put up a change log once I've got a sync on my servers. Hopefully it should be in the next couple of hours, if not it may be tomorrow morning european time.

There's a new revision coming indeed with a different power management
chip. It's functionally identical to the existing one, but requires a
new driver and bootloader that weren't part of 4.1.1.

-As was mentioned several times in this thread already, I'm not
allowed to answer that question.

-Even if I was allowed to answer it, it's not precise enough anyway as
there are many versions of Galaxy Nexus.

-The -release branches are implementation details, you should never be
using them directly. That's why there's no manifest for them.

-I'll update jb-release if there's a new release coming from it.

At no point did I say that the change log I produced was for a specific device. The two revisions of the AOSP that it relates to are clearly shown.

As I've streamlined the process I have for generating change logs, and because you asked so nicely, here's one for JRO03D to JZO54K with hyperlinks to the projects and commits;

Hi Al Sutton !

I want to comment that this changelog isn't complete because it show differences between 

JRO03R and JZO54K builds, but stock ROM for Nexus 7 is based on build JRO03D.

A good example of missing data is the commit responsible for enabling landscape on Nexus 7. You can see that the config "allow_rotation" is been setted to true on this commit: https://android.googlesource.com/platform/packages/apps/Launcher2/+/d7d37b134b7a3b12858ff099069eba369a6b5373%5E%21/#F0

Follows a more complete changelog:

https://docs.google.com/open?id=0By0xlEB4eHqpVmJseVBvcEkzdGc

To generate this changelog I used the command: 

repo forall -pc git log --oneline --no-merges android-4.1.1_r1.1..android-4.1.2_r1
