= Timeline =

We now adopt a fixed cut-off date scheme. We will release twice a
year. The upcoming 4.8 timeline are as followed:

* Last posting date: September 16, 2016
* Hard code freeze: September 30, 2016
* RC1: TBD
* Release: December 2, 2016

Note that we don't have freeze exception scheme anymore. All patches
that wish to go into 4.8 must be posted no later than the last posting
date. All patches posted after that date will be automatically queued
into next release.

RCs will be arranged immediately after freeze.
