2012/03/23 - Mythbuntu is looking to switch from releasing with every development to just on the LTS releases, and participate in the point releases to pick up the new hardware. Recommended email to techboard on the subject and apply to be part of LTS, and determine term. Release manifest to be updated for Mythbuntu pending
techboard response.

2012/01/30 - No Debian release events scheduled during Pangolin. see: http://lists.debian.org/debian-devel-announce/2012/01/msg00009.html for latest update.

 * Review schedule and tweaks:
    - https://wiki.ubuntu.com/PrecisePangolin/ReleaseSchedule
    - Freeze milestone adjustments requested? (Planning, Feature, etc.)
    - Translation deadlines - 2 days before indicated. How denote?

* LTS support
   - https://wiki.ubuntu.com/RecognizedDerivatives (proposals for consideration)
   - 5-year LTS, how fits in the schedule, options for flavors.
   - 2-year hardware updates, coordinate kernel and installer (backport kernels in install media, LP #607657), ISO verification on new hardware.
   - cleanup of WIKI pages to reflect derivatives and LTS expectations:
       - https://wiki.ubuntu.com/LTS
       - https://wiki.ubuntu.com/DerivativeTeam/
       - https://wiki.ubuntu.com/DerivativeTeam/Derivatives (missing lubuntu, update with Ubuntu (vs. desktop and netbook, etc.)
       - ... what other pages?

DIF is after Christmas
doko expressed concern that Debian bugfixing happens over Christmas break period, then 10 days to get to testing
No impact if DIF is during rally because cjwatson won't be there anyway

Rally significantly before alpha 2

FeatureFreeze at the same time as 10.04.4:
 - Most 10.04 stuff comes before FF

UIF and BetaFreeze 1 week after FF
 - UIF important to let docs and translations settle

Language pack rebuild:
 - Friday before all milestones after and including b1

Do we put out RC intended as release candidate
 - Put RCs on ISO tester, instead of tagging and distributing ISO as "release"
 - Hit a point in time where images coming out "could be release"

Should be in RC phase when we change identifier strings to final release name

How do users tell they have an RC?
 - They didn't get it from ubuntu.com
 - Also want to be directing more people to tester to get better coverage

If release is ready earlier, we can start doing hardware certification sooner
Certification has preliminary results at beta1
 - Need enough time for kernel to fix issues
 - Retest at b2? No, issues not necessarily fixed yet
 - Since b1 is post-FF, shouldn't be breaking HW that worked

Need interlock with archive rebuilds
 - a2
 - b1
 - b2
 - Universe rebuild at DIF

 - 3 months and a bit
 - Lucid .1 was late, intended to be July, rally interfered
 - Doesn't contain any kernel/X/HWE backports, just SRUs
 - Derivatives? Usually not
 - LTS upgrades are not offered in update-manager until .1

FeatureDefinitionFreeze should have schedules for landing time

Flavors and derivatives (https://wiki.ubuntu.com/RecognizedDerivatives ):
 - Proposals to TB
 - Designating flavors as "LTS"
   - Based on what seemed to happen with Kubuntu
   - TB evaluation of "quality" is soft, not easily codified
 - Mythbuntu planning to switch to only having CDs for LTS
   - mythtv in PPA
   - Hoping to ensure HW freshness kernel/X backports
   - Lifecycle will be 27-28 months (LTS-LTS + first point release)

LTS wiki pages need to be updated
Derivative wiki pages need to be updated

Out of date web pages have no contact
 - Link on web page under "Report a problem"

When are dailies available?
 - Immediately
 - Alpha1 is a designation so we don't have to worry during feature dev

Rebuilding daily builds if they fail smoke tests?
 - Don't know details, but release team will be involved
 - Will there a subscribable feed with results of QA? https://blueprints.launchpad.net/ubuntu/+spec/other-p-builds-smoke-testing if you subscribe to this you'll be up to date on status, we'll have a simple dashboard online in the next 4 weeks.
 - May just push to ISO tracker
