On October 20 on the official Second Life blog, Linden Lab announced
some details about some upcoming planned changes to the grid, as well as one current change to it's website, "
There’s a lot going on with Second Life these days, and we wanted to talk about a few of the projects that are either out or in the works!"
The first thing on their list was "Project Valhalla," which replaces the old Internet viewing framework with one that supports more recent technologies.
A new age of modern HTML5 content is upon us, and
we're overhauling the way shared media (aka "media on a prim") works so
that you can enjoy all kinds of modern web content within Second Life. Chromium Embedded Framework (CEF) is coming to replace the aging QTWebkit framework. What you can now see in a Project Viewer
is the latest released version of Chrome - so it will render all modern
web technologies - like HTML5, CSS3, WebGL; has the latest security
patches; and will be easy to keep updated to a recent version. What does
this mean for your Flash content? What about Quicktime? They may still
work, but because both can only be viewed if the user has correctly
installed a 3rd party plugin, we can't promise support and you
shouldn’t expect that it will work for everyone. Standard HTML5 is the
way of the future and this Viewer will enable it for anyone. There are still bugs to squash, and we’re iterating quickly to bring you a smooth inworld media and browsing experience.

On the official forums, Linden Lab invited residents to leave comments o
n a thread on the topic. Among those posting was AI Austin, "An initial test of the Project Valhalla viewer on my Windows 10 setup
did have the media texture screens showing a quicktime server .sdp
stream and a looping MPEG-4 video on the screens (as shown in the image
above), but I am not sure if that is because of other elements I already
have installed or if its included by default in the Valhalla viewer."

Next was an "Avatar Rendering Complexity" feature.
A new *Avatar
Maximum Complexity* control lets you prevent expensive-to-render avatars
from lagging you; any avatar over the limit is displayed as a solid
color rather than rendering in full detail. A default limit is set based
on the rendering performance of your system. You'll also get a notice
when your own rendering complexity changes, and an indication when
you're over the limit of too many of the avatars around you. Bundled together in this Viewer is a change that allows
you to create and quickly change presets of your graphics settings, so
as you go from a club to an art gallery, to the beach, or to your home,
you can quickly adjust your settings to fit the scene.
Apparently if an avatar goes over the limit you set, it's displayed as a simple, single color, mannequin-like shape.
On
the Linden-created forum thread on the topic, one resident expressed concern, calling it "giving avatar makers just another migraine to now deal with." Another felt it would encourage them to be more efficient. In
New World Notes, Hamlet Au commented, "If it's implemented well, this could be an important feature to improve
overall performance. At the same time, the very fact that it's necessary
makes me sadly smile, because it reflects a paradox with user
creativity in Second Life that's existed from the beginning: By making Second Life as open a creative platform as possible, Linden
Lab unleashed incredible amounts of inventiveness that continues to be
impressive (if overwhelming). At the same time, because it
is so open, there's also abundant opportunities for creativity which is overly complex and laggy."
For now, one can try out the feature on the
Release Candidate Viewer.
A few other details were briefly mentioned. Sorting notifications into categories, removing Flash from the secondlife.com website due to security concerns, a change that
"now prevents loss of no-copy items due to a failed rez," and continuing the HTTP Project for improved texture loading.
