Highlights and Key Successes
============================
Linaro also held its first Virtual Connect event on 13 - 17 August,
2012. This online event used Google+ Hangouts on Air and was streamed
and recorded via YouTube. Members of the various Linaro Teams provided
informative, educational and exciting sessions that allowed for public
viewing and participation.

The Android team created stable Jelly Bean builds from AOSP and an
Android benchmarking platform to automate many of the tests in the
AOSP codebase.
The Developer Platform Team announced USB Host enablement is now
available in LAVA and that all packaged linux-linaro kernels are now
cross-compiled and boot tested via LAVA before they are uploaded to
Linaro Overlay PPA. Additionally, U-Boot-Linaro is now based on the
latest upstream release--v2012.07.
Postmortem and Lessons Learned
==============================
This cycle was fairly low key: lots of people were out for vacations
and many others were attending external conferences such as Linux
Plumbers.
One issue of concern was the deployment of an infrastructure project
on the last week before release.
A the new django application was deployed on snapshots.linaro.org that
disrupted several builds on the Friday before the release. The issues
took one week to resolve.
The issues are:
- The deployment was not communicated and broadcast properly
- Build maintainers were not given proper warning
- deploying new functional software on a Friday with no one
available on the weekend for emergency
- deploying during a release week
A big "thank you" is in order for Georgy Redkozubov (gesha) for his
help and availability in troubleshooting and getting it fixed.
