Just like jaws did last week
I'm taking over for dolske
this week to talk about stuff going on with Photon Engineering. So sit
back, strap in, and absorb Photon Engineering Newsletter #14

If you've got the release calendar
<> at hand, you'll note that
Nightly 57 merges to Beta on September 20th. Given that there's usually a
soft-freeze before the merge, this means that there are *less than 4 weeks
remaining* for Photon development. That's right - in less than a month's
time, folks on the Beta channel who might not be following Nightly
development are going to get their first Photon experience. That'll be
pretty exciting!

So with the clock winding down, the Photon team has started to shift more
towards polish and bug-fixing. At this point, all of the major changes
should have landed, and now we need to buff the code to a sparkling sheen.

The first thing you may have noticed is that, after a solid run of dogefox
the icon has shifted again:

The second big change are our new 60fps loading throbbers in the tabs,
coming straight to you from the Photon Animations team!
Here's an animated GIF!
