<br>
I would add a 3rd option:<br>
<br>
3. Feature freeze during rc<br>
<br>
For two reasons:<br>
<br>
a) It forces people to test, and pushes back on introduction of new<br>
code, thus improves quality,<br>
b) keeps maintainers sane. We already have one -rc branch to manage,<br>
and at least one stable branch, per project (we'll have to decide how<br>
many stable branches we want to keep active). Adding features into<br>
master or a staging branch would add a 3rd branch to maintain for<br>
each project.<br>
<br>
I know the downside is that contributors may have to wait before seeing<br>
their features merged. As a side-effect, it forces them to do more<br>
testing than writing new actual code, but this is exactly what we are<br>
doing right now as maintainers.<br>

Sounds good.<br>

Good idea.<br>

<br>
Yes. We should compare this system with others used e.g. at Google.<br>
Etienne Bergeron has interesting feedback on this topic.<br>
