For those of you who are keen on hands-free avatar expressiveness in the virtual environment of Second Life comes a surprise third-party viewer from vr-wear.com. This beta viewer for Windows or Mac OSX uses a camera to track your head and expressions, and convey that to your avatar.

At present, it is all a little rudimentary, and there isn't any back-end support for sending much in the way of ad-hoc avatar motion through the Second Life servers, so the system is limited to what can be supported. At present, that appears to be lip-sync, nodding and head-shaking, surprise and smiling, and head-tilting to the left or right.

The Second Life viewer dev team has been working furiously away for some time now, and you may be forgiven for wondering where the fruits of that labor are. It has, after all, been some time since we've seen a new viewer other than emergency security fixes.

There are lots of little things in this viewer, mostly bug-fixes. What is particularly peculiar is that whispering seems to be back. Whisper was a short-range chat option that was discarded from the Second Life viewer back in 2005 due to it being confusing both conceptually and in the user-interface. Whispering has a 10 metre range and while it has been a deprecated script function for years is still available to scripted objects.

The Imprudence project now has its first release candidate viewer for Second Life available, and far sooner than we expected. It's impressive work for a first release candidate as well. We've not had such a fast and smooth viewer experience since Nicholaz "The Mad Patcher" Beresford's series of Second Life viewers. Indeed, many of Beresford's patches are also a part of the Imprudence project.

Imprudence necessarily replaces proprietary fonts with Liberation Sans and Bitstream Vera Mono, which look a little peculiar the first couple of times out, but score high on improved readability. There's no audio either, yet, as the proprietary FMOD audio system has yet to be replaced with OpenAL, but that is coming soon, we understand. As for the change from Kakadu/KDU to OpenJPEG -- this is supposed to be fractionally slower, but honestly, the whole experience was so smooth we never noticed.

The 1.21 series of Second Life viewer release candidates has come to an end and has "gone gold" as they say. The 1.21.6 viewer today replaces the 1.20 viewer as the official Second Life viewer.

As yet, Linden Lab has not announced the update, nor provided release notes for the new viewer, but that's alright, because we've got that information for you. The list of changes from 1.20 is quite a long one. Seriously. Hang on to your hats, because nearly every part of the viewer got some loving from the Lab engineers. Everything from group chat moderation to some long standing cleanups of text that was literally years out of date.

Check after the fold for the the full release notes (as nearly as we were able to assemble them, in the absence of a final set from the Lab), and download links to the new viewer.

Well, at last we know what all the fuss was about with all the sudden software updates over the last week for the Second Life servers that caused so much disruption during the last few days. It appears we were on the money with security fixes, and exploitable vulnerabilities have received urgent attention.

As a result a new Second Life viewer is available for download now -- that's 1.20.17(98669) -- and you can expect a new Release Candidate viewer (RC5) very very soon. Both are likely to be mandatory updates.

So, what's all the fuss about?

New Linden Lab CEO Mark Kingdon is still making irregular postings to the official Second Life blog. It's all heady and exciting stuff, to be sure. Growth, focus on improvement of the new user experience, simplified registration, and so on.

Yet something seems to be missing. What's missing is anything that excites you if you're already a Second Life user. There's plenty here to entice those who aren't already users, but if you're already one, there doesn't seem to be anything much in them for you to get excited about. Put together with some other pieces, however, it certainly creates an interesting picture about future direction for Second Life.

A new Second Life viewer is available. Not a release candidate, but an update to the 1.20 series -- what's generally referred to as an 'official' or production viewer. The version number for this release is 1.20.16 (97603), and only contains one listed change over 1.20.15.

The lone change appears to be security-related. The text of the change (not yet available in Wiki release notes) is "Discard messages sent over UDP that should not be trusted."

It isn't clear exactly which messages those are, precisely, and whether they might be sent from servers or spoofed from other hosts (or if they should simply be being carried on another transport protocol) -- however if it was important enough to release a fresh production viewer with just this one change, it is likely to be an important upgrade for users.

The new viewer is available for download now for Linux, Windows, or Mac (universal binary). We assume that if you've had problems running the 1.20.15 viewer, 1.20.16 will not work any better for you.

Linden Lab has not yet announced this release on any of its blogs.

Linden Lab have been working very hard to attempt to bug-fix and stabilize the SLS-1.24 Mono-enabled Second Life simulator server software (try saying that three times, fast). Since Monday, the 8th of September, we've counted no less than 19 distinct versions of 1.24.5 that got far enough along to test.

Right now, the top candidate (and the version that has been rolling out onto the Second Life grid) is build 96115. A test rollout of build 96378 was attempted, but was somewhat crashier than 96115, so it was replaced with the slightly earlier build. There are several later builds already being tested and assessed as candidates for the next rollout, the latest being build 96505. There's quite a list of fixes, almost (but not entirely all scripting related). Notes for builds up to 96378 are available, however it isn't yet clear what any more recent builds might contain.

While all this is going on, the viewer team has managed to crank out a new release-candidate (1.21-RC2), which runs on the Mac PPC, and for those of you who were having that nasty crash-or-freeze-every-minute-or-six problem, or issues with sculpt textures, there's a fix for those too.

Linden Lab has released the fifteenth 1.20 Second Life release candidate viewer. Release candidates start counting from zero, so the first one in the series is RC0.

This release looks like the final release in this cycle, unless something quite nasty appears. Mono is expected in viewer 1.21, and SLS1.24 (SLS1.23 is deploying this week) -- thus, there is nothing particularly earth-shattering in this release.

Linden Lab has released the fourteenth 1.20 Second Life release candidate viewer. Release candidates start counting from zero, so the first one in the series is RC0.

If an overall 50% lower crash rate, measured across-the-board doesn't appeal to you, or improved quality texture decoding, how about the fact that the silver skin can now be disabled and replaced with an original recipe UI schema. Okay, so there's still a couple little glitches with that, but you can do it. Also it defaults to the familiar blue UI, which will please a lot of users.

Linden Lab are watching your choices as well. The viewer now reports which skin you have loaded so that information can be pulled out of log-files (or, so a web-site or web-service used by the viewer can offer you HTML skinned in a compatible set of colors) -- We think it's more the latter than the former, but it'd be silly not to gather usage data on skins.

Linden Lab has released the thirteenth 1.20 Second Life release candidate viewer. Release candidates start counting from zero, so the first one in the series is RC0.

We're not sure if this is the RC with the least number of changes or not, exactly. Aside from a localization fix where the viewer was still talking about First Land, the remaining three items all seem to constitute code reversions -- essentially undoing what has been done.

User-Interface skin switching isn't in this release. We're going to go out on a limb and suggest that you won't see that for a couple weeks at least.

Dusan Writer has spotted an HTML comment in the source for search.secondlife.com which says "<!-- placeholer page for XBOX, PS3, and iPhone versions of client when they launch next real soon now -->"

Definitely quite the tease. Certainly, Second Life can be made to run on a PS3 (and there's at least one enterprising user who has had some success on that front); the Xbox 360 would present a much more considerable technical challenge; and as for the iPhone, well, Linden Lab has been making noises about lighter-weight clients/viewers for some months.

We're not sure quite how much credence to put to the message, however, as "real soon now" is a piece of engineer slang/sarcasm generally taken to mean "Whenever, when it's ready, maybe never". However this could neatly dovetail with Kapor's "very important announcement" coming up in seven days.

The RealXtend team has released the latest version of their extended, viewer and opensim-based system code. This brings realXtend up to version 0.3.

The viewer sports new basic avatars (three), attachments direct to the avatar (rather than to a bone-based attachment point), prim sizes increased to 128 metres in any dimension, fixed assorted crash bugs and more.

The server code handles the support for these features, along with a bunch of bug-fixes, Skype support, inverse kinematics and variable avatar walk-speeds.

Linden Lab has released the twelfth 1.20 Second Life release candidate viewer. Release candidates start counting from zero, so the first one in the series is RC0.

Linden Lab says this release candidate cycle will be extended, and some of the skinning project that was slated to come after 1.20 is being moved up, so that users will be able to switch the UI skin before this becomes the official viewer, rather than in some unspecified future release.

So, there will be a couple more release candidates before 1.20 becomes official, and it is pitched to take a bit longer between them.

This edition fixes some more crashes and freezes, but still has that nasty buffer-rendering offset glitch that afflicts snapshots, among other things.

Linden Lab has released the eleventh 1.20 Second Life release candidate viewer. Release candidates start counting from zero, so the first one in the series is RC0.

Linden Lab says that it is aiming for 1.20 to go live by the end of June, which suggests only two more release-candidate iterations -- so what you're seeing is very close to what the official viewer will be in a couple of weeks. Release notes are not included in the installer. This version apparently fixes the crash-on-startup with the Mac PPC, and fixes some of the snapshot problems: The UI is no longer silently included in the snapshot when written to disk, but the black bar (and occasional random pixel garbage) down the left-hand side is still there.

The thread-watchdog has been disabled for the rest of this series of RCs, the first-login-fails-with-Vista also appears to have been corrected, and pixel-garbage around avatar imposters has been fixed. There are an additional six crash fixes.
