Every [[https://wiki.mozilla.org/RapidRelease/Calendar 6 weeks]] we release a new version of Firefox.  When we do that, our code which developers check into the nightly branch gets uplifted (thing of this as a large [[https://wiki.mozilla.org/Buildbot/Talos/Sheriffing/Tree_FAQ#What_is_a_merge merge]]) to the Aurora branch.  Now all the code, features, and talos regressions are on Aurora.  The same thing happens with Aurora, we uplift that to Beta.

This affects the Talos Sheriff because we will get a big pile of alerts for Mozilla-Beta and Mozilla-Aurora.  These need to be addressed rapidly.  Luckily almost all the regressions seen on Mozilla-Beta will already have been tracked on Mozilla-Aurora, likewise all alerts that now show up on Mozilla-Aurora were already tracked on Mozilla-Central.
