The official timeline is on Google Online Security blog [1]. BUT you have to replace "41" with "42" [2].
SO, what changes? From version 42, the current "beta", which according to schedule [3] should become "stable" in a week on the 14th:
- certs that expire in 2016 will be yellow
- certs that expire after 2016 (like xkcd's) will be red
Nothing else will change after 42, and Firefox will follow next year [4]. Certs expiring in 2015 are fine.
Also note that this only affects the lock icon and "https" color, there will be no warning screen AND no connection will be blocked.
EDIT: thanks to the author for amending.
