Hello everyone, We have just released a big Ubuntu Touch update to the stable channel marked as OTA-4. The image numbers for selected devices are: krillin #23, vegetahd #3, mako #20 and generic #15. It's a much bigger release than the previous updates because it's the first official vivid-based image in the stable channel. Because of this it's also really hard to create a proper changelog for all the changes introduced by this update. The whole system underneath the images changed, so there's no common baseline for bugs as well. * Short human-readable changelog: http://people.canonical.com/~lzemczak/landing-team/ota/ota-4.changelog * Bugs fixed by this release: https://launchpad.net/canonical-devices-system-image/+milestone/ww22-ota IMPORTANT NOTICE! Because of the switch to vivid, this update has also two notable shortcomings. First, because the baseline changed, the update weights over 400 MB so it might take a while to download on slower internet access. The other is, also related to the switch, the update process might take longer than usual. On start apparmor profiles need to be regenerated which means the first boot after the upgrade might take long depending on the number of installed applications (even up to 30 minutes). Currently there will be no visual indication of the profile regeneration, so please be patient and wait until you see the UI appearing. As with the previous release the update will be deployed in phases but in the next ~24 hours the OTA should be available to all users. If you get the update earlier and notice any critical issues, please be sure to inform us as soon as possible so that we can halt the update before it reaches to everyone. Highly unlikely, but we prefer to be absolutely safe. Enjoy! Best regards, -- Łukasz 'sil2100' Zemczak Foundations Team lukasz.zemczak@xxxxxxxxxxxxx www.canonical.com
