Here is a proposed release schedule for 0.14.0. Like for previous major releases I've added 6 months to the previous release schedule (#7679), even though 0.13.0 was moved forward a month compared to the original planning. This means the planned release of 0.14.0 will be a month later compared to the planned release date of 0.12.0 last year.
Proposed release schedule for 0.14.0:
2017-01-02
-----------
- Open Transifex translations for 0.14
- Soft translation string freeze (no large or unnecessary string changes until release)
- Finalize and close translations for 0.12
2017-01-16
-----------
- Feature freeze (bug fixes only until release)
- Translation string freeze (no more source language changes until release)
2017-02-06
-----------
- Split off `0.14` branch from `master`
- Start RC cycle, tag and release `0.14.0rc1`
- Start merging for 0.15 on master branch
2017-03-01
-----------
- Release 0.14.0 final (aim)
(yes, "easy to implement" is a joke)
