Releases from KDE SC 4.12 and beyond

Motivation

The main motivation for this change is to reduce the amount of time between releases, making us able to deliver new features faster to our users while keeping if not improving the current quality.

Proposed changes

The time elapsed between big releases (4.12, 4.13, 4.14...) will be of 3 months (instead of 6) having the following structure:

Two month for merging features
One month to prepare the release

Things to take into account as a Maintainer

Since we will be decreasing the amount of time for testing, it is specially important that only features that are reviewed and stable are merged into master. Saying it in another way master should be always in a state where we can make a release from it.

Tentative schedule for 4.12

Start of development: July 10, 2013 (Potential moment of 4.11 branching)
- During this time merging of STABLE features is allowed
Branching of 4.12: October 15, 2013 (Two month after 4.11 release)
- Beta 1 is created ASAP
- Strings are frozen
- Dependencies are frozen
- Artwork/Bindings frozen
- API frozens
Release candidate: October 30, 2013 (2 weeks after Beta 1)
Release 4.12 final: November 15, 2013 (One month after 4.12 branching)
Release 4.12.1: December 15, 2013
Release 4.12.2: January 15, 2014

Tentative schedule for 4.13

Start of development: October 15, 2013 (Branching of 4.12)
Branching of 4.13: January 15, 2014 (Two month after 4.12 final)

Release candidate: January 30, 2013
Release 4.13 final: February 15, 2013 (Three months after 4.12)

In a picture

Distributions

Benefits:

Since we have shorter release cycles it is more probable that distros will be able to pick up more recent version of KDE SC
Master will be always in a releseable state
Cycles with less changes, will have less bugs
Since cycles will have less changes, testing will be easer

Inconvenient:

Instead of 4 or 5 minor releases only 2 will be scheduled

There is NOTHING preventing us to schedule '''more''' minor releases if we have people taking care of them,
 exactly as it happens right now (we have had un-scheduled .5 and .6 releases)

Translators

While there will be only one month to translate new or modified strings, the amount of changes in every release can be expected to be minor as well.
