Firestorm 7.2.2 release overview

On Tuesday, November 11th 2025 (SLT), Firestorm released version 7.2.2.79439 of their viewer.

The primary aim of this release is to achieve parity with the Lab’s most recent releases and to add further updates to features added to the June 2025 Firestorm 7.1.13 release.

Note that the following is not a complete review of the 7.2.2 release and all the changes made therein; it focuses on the more visible and user-facing updates. Those requiring a list of all changes and updates, including all bug fixes, etc, should refer to the Firestorm 7.2.2 release changelog, which also provides all proper credits for the work.

General Notes

Installation

  • Only download Firestorm from the Firestorm website. Do not utilise and other third-party site purporting to offer the Firestorm viewer, and remember Firestorm will never ask for log-in credentials in order to download a release version of their viewer.
  • There is no need to perform a clean install with this release if you do not wish to.
  • Do, however, make sure you back-up all your settings safely so you can restore them after installing 7.1.11.

Linden Lab Updates

This release brings Firestorm to full parity with the following recent official viewer releases from Linden Lab:

Viewer 2025.04 – Chat Mentions

Version and release notes:  2025.04 – 7.1.14.15192634334 – May 2025.

  • Chat Mentions: support for chat mentions allowing  for better communication and awareness in local chat.

Firestorm Updates

New Features for 7.2.2

Disable Connecting to Neighbouring Regions (Navigation and Teleporting)
  • Preferences → Move & View → Movement → Disable connecting to neighbouring regions.
  • Request: FIRE-2325.
  • When enabled:
    • Prevents the viewer from connecting to neighbouring regions (which are ignored by the viewer), and only the current region (login/teleport destination) is connected, effectively isolating it.
    • This may improve performance for users with weaker computers or slower connections, assist multi-region event setups by lowering client overhead and reduce unintended neighbour interactions.
The new Preferences option to disabling the viewer from connecting to neighbouring regions, complete with the tooltip, which should be read to understand the implications
  • Limitations:
    • Region crossings will not function normally, as neighbouring regions are not visible or connected to the viewer.
    • Only direct teleports and logins to regions will work reliably.
    • The sense of world scale and continuity is reduced, and travellers or explorers may find it limiting.
New Imposter / Avatar Imposter Exclusions (Inventory / Avatar Appearance)
  • Preferences → Graphics → Rendering → Exclude Animesh Impostor Avatar.
  • Request: FIRE-35735.
  • When selected, allows a user to keep using the imposter system, but protect Animesh avatars from not animating or from having rendering issues (e.g. missing attachments).
The new Impostors option for protecting Animesh avatars from not animating or from having rendering issues
  • Comprises four options:
    • None: Default, don’t exclude any avatars.
    • User: Exclude only user avatars which have Animesh attached to them.
    • Control: Exclude only control avatars.
    • Both: Exclude both User Animesh avatars and control avatars.
New Snapshot Framing Guides and Settings (Photography / Snapshot Floater)
  • The snapshot frame overlay and composition guides were added to the Snapshot floater with Firestorm 7.1.13.
  • They allow the user to:
    • Overlay their in-world view with a frame mirroring the selected image size selected from the relevant image size drop-down, with the parts of the in-world view outside of the image capture size rendering in monochrome (Show Capture Frame)
    • Optionally display a composition guide overlay as a set of yellow lines within the image frame on their world-view.
    • Use a series of Debug settings to customise the snapshot frame.
  • Firestorm 7.2.2 enhances these frame overlays and guides with additional options, access via a  new # button.
  • When clicked, this button allows the user to:
    • Adjust the thickness and opacity of the frame guides displayed in-world by the viewer without having to use the Debug Settings.
    •  Select from an expanded down-down of guide styles:
      • Rule of Thirds.
      • Golden Ratio: – one of Top Left, Top Right, Bottom Left or Bottom Right .
The Snapshot floater showing the frame overlay option (1) and the yellow composition guide (2) using the Rule of Thirds, added to the floater as a part of the Firestorm 7.1.13 release. Also shown is the new Firestorm 7.2.2 # button (3) which opens the Frame Guide Settings floater, allowing the user to customise the frame guides and select from the composition guide drop-down (defined in the text above)- click for full size, if required

Firestorm Avatar and Animesh Poser

The Firestorm avatar and Animesh poser system was introduced with the release of Firestorm 7.1.13 as a re-write of the Avatar poser system developed by NiranV Dean (and found on the Black Dragon viewer). For assorted reasons, that release of Firestorm did not have any associated overview in this blog, therefore for detailed information on it, please refer to the following links:

Firestorm 7.2.2 introduces a large number of improvements and updates to the Avatar and Animesh Poser, all of which are summarised in the viewer changelog, to which those interested are referred to for details.

Other Notable Improvements / Updates

Note: for bug fixes, etc., please refer to the viewer changelog

Inventory, Appearance & Avatar
  • New option to automatically reset skeleton upon standing up, which is also automatically broadcast to surrounding avatars as well: Preferences → Firestorm → Extras → Reset avatar skeleton after standing up.
  • New Stop button on the link replacement floater (Right click inventory item → Replace Links (FIRE-29394).
  • ‘Delete from outfit’ context menu entry when right clicking on an item in an outfit, in the Appearance window, Outfits tab.
    • This is useful for when you mistakenly added some HUD or anything else you didn’t want in your outfit, and is simpler than going inside the inventory and deleting the links from the outfit folder.
    • Note that only links are deleted, not actual inventory items.
    • Accessed via: Appearance → Outfits tab → Right click item → Delete from outfit.
  • Visual warning about too many saved outfits:
    • If a user has a large number of saved outfits, this can cause the viewer to freeze for a short time when opening the Appearance panel or when searching for saved outfits on slower hardware.
    • Therefore, when the user has over 200 saved outfits, they will now see this warning notification:
      A large number of outfits were detected: [AMOUNT]. This may cause viewer hangs or disconnects. Consider reducing the number of outfits for better performance
Radar, Navigation and Teleporting
  • New Radar option to set the maximum range for results to be obtained (FIRE-35815):
    • World Menu → Radar (or Radar Toolbar button)→ Radar Options drop-down → Limit Results to specific Radius → open range panel at the foot of the floater.
    • Use the slider to set the desired radius, or manually enter the radius.
Firestorm 7.2.2 radar range option and slider / entry field
  • An option to View Chat Transcripts’ added to the Nearby People and Radar right-click context menu.
  • Option to show yellow beacons at region corners to help avoid region boundary disconnects, especially when driving or flying: Top menu → World → Show More → Beacons → Show → Region Corners (FIRE-33085).
  • The maximum zoom on the World Map has been increased to match the official viewer (FIRE-35934).
Communication + Sound and Media
  • Functionality to save and restore open resident-to-resident IMs from the previous session (Group chat sessions are not always ready in time during start-up, making their restoration unreliable): Preferences → Chat → Notices → Restore conversations with residents from previous session.
  • Option to enable / disable auto-completion when typing @ mentions in chat: Preferences → Chat → Typing → Enable automatic @ mentions window while typing in chat bars.
New Chat Preferences to restore resident-to-resident IMs (left) and to enable / disable auto-completion when typing @ mentions (right)
  • Separate conversations opacity options, together with new checkbox to allow the conversation floater to abide by the active opacity when it is focused, so that way it can have its own inactive transparency separate to everything else – FIRE-35804.
    • Preferences → Colours → Miscellaneous → Floating Window Opacity → Conversations.
    • Preferences → Colours → Miscellaneous → Floating Window Opacity → Use Active Opacity value when the conversations window is focused.
  • Sound Explorer:  new buttons in Sound Explorer to mute all attached, rezzed or gesture sounds for a specific avatar
    •  Muted sounds are re-enabled via the Asset Blacklist.
New Sound Explorer checkbox for muting specific sounds from an avatar
  • Asset Blacklist: new Flags column to the Asset Blacklist to denote if the muted sound is one of  Avatar Worn Object Sounds, Avatar Rezzed Objects Sounds or Avatar Gesture Sounds.
  • Media on a prim (MOAP) interaction option can now be set individually (when set, does not require a first click to focus before interaction can begin): Preferences → Sound & Media → Media → Media first-interact.
Firestorm 7.2.2 MOAP first interaction options
Miscellaneous Updates
  • Show On-Screen Console shortcut revised to ALT+SHIFT+`.
  • Area Search improvements:
    • Added functionality to save Area Search flags and options as defaults when the floater is opened: 
      Top Menu → World → Area Search → Filter Tab → Save as Default.
    • Improvements to more reliably send all objects and not just objects in front of the camera.
  • Camera:
    • Added an option to disable the reset buttons in the camera floaters (prevents the centre bullseye of the orbit and move camera controls from resetting the camera): Preferences → User Interface → Interface Windows → Disable camera controls reset buttons
    • Added a TPP preset button to the added to the right of the front, side & rear buttons on both the small and regular camera floaters – FIRE-32595.
  • Added Default buttons for Preference → Move & View → View sliders for ease of resetting to default values – FIRE-32710.
  • Height of Preferences floater increased for improved readability.
  • Graphics: Draw Distance VRAM Optimization changed to be optional:
    • Preferences → Graphics → Rendering → Reduce Draw Distance when VRAM is full or
    • Top Menu → Developer → Rendering → Reduce Draw Distance when VRAM is full.

Feedback

Sorry, no real feedback from me on 7.2.2, my personal situation has been such that I only managed to try the 79438 beta and the 78439 release less then 24 hours before the release of 79439.

2025 week #46: SUG meeting summary

Celestial Vale, August 2025 – blog post

The following notes were taken from the Tuesday, November 11th, 2025 Simulator User Group (SUG) meeting. These notes form a summary of the items discussed, and are not intended to be a full transcript. They were taken from the video recording by Pantera, embedded at the end of this summary – my thanks to Pantera for providing it.

Meeting Overview

  • The Simulator User Group (also referred to by its older name of Server User Group) exists to provide an opportunity for discussion about simulator technology, bugs, and feature ideas is held every other Tuesday at 12:00 noon, SLT (holidays, etc., allowing), per the Second Life Public Calendar.
  • The “SUG Leviathan Hour” meetings are held on the Tuesdays which do not have a formal SUG meeting, and are chaired by Leviathan Linden. They are more brainstorming / general discussion sessions.
  • Meetings are held in text in-world, at this location.

Simulator Deployments

  • On Tuesday, November 11th, the SLS Main channel was restarted without any deployment.
  • On Wednesday, November 12th:
    • All RC channels other than BlueSteel and Preflight should be updated with a new simulator update (Imbu). This “has a couple of performance memory fixes in the simulator. It fixes an issue with region names that contain a ‘.”
    • The BlueSteel and Preflight RC channels will be restarted without any update.

SLua Work

  • Rider Linden has been refactoring some of the official native VS Code plugin for LSL and SLua, and is planning on opening it up and making the repository public on Friday, November 14th.
  • There was a SLua update on the beta grid during week #45:
  • Since then, Harold has been cleaning up the bugs found with that release, with the aim of getting a limited deploy to a few simulators on Agni (the Main grid) later in November. This will be to simulators hosting Lab-managed regions; “volunteer” regions from region holders will be accepted further down the deployment road.
  • Viewer-side support for SLua is also defined as “iffy” – an update to the viewer has been anticipated, but work on it is pending Harold competing the work fixing the bugs in the simulator deployment.
  • A question was asked as to why vectors and quaternions are immutable in SLua. In reply, Harold stated:
Vectors are immutable because that’s just how it is in Luau, they’re not garbage-collected, they’re a value type. Storing a vector is exactly as cheap as storing a number. Quaternions _are_ garbage collected but they’re immutable for symmetry with how vectors work, and honestly people don’t tend to create a bajillion of them per frame so IDK if making them mutable is worth it. GC overhead isn’t something you have to worry about so much since we abstract away most of the GC details. 
They’re not reference types so mutability probably wouldn’t work the way anyone would expect without special language support that would be hard. In reality, they were never mutable in LSL either, it just sort of pretended they were by hiding the fact that it was actually making a whole new vector.
    • Harold also noted that he settled on the canonical name “quaternion” in SLua because it’s easier to google what to do with them compared to “rotation”(which could mean anything), but he is open to ideas on this. The term appeared to find acceptance among those at the meeting, with the conversion flowing through the middle third of the meeting.
  • It was asked if it would be possible to add more functions to SL standard SLua libraries – e.g. someone writes really commonly used functions that might then – be included in common/native libraries?
    • The reply was yes, it is possible, but currently LL are being conservative because while it is relatively easy to add things, it is harder to removed them later if they turn out to be a bad abstraction or similar.
    • This led to a broader discussion on SLua scripting, etc.

In Brief

  • Leviathan Linden has been carrying out Voice related work, but is now “almost done” with that. He is currently focusing back on simulator crash and performance issues.
  • Leviathan also provided some feedback on a question from his “office hours” meeting on November 4th:
[I was asked] last week about some bugs in llBase64ToString() method. Apparently it was designed to replace C0 control codes (chars with numerical values < 32) with “?”, and fails to replace a C0 character if it is at the end of the string. I looked at the code and as far as I can tell that really is a bug… we skip the last character of the string for an “off by one” error. It has been around since before 2007. The question is: can we fix it?
    • It was suggested that either LL should make a new llBase64ToStringFixed() LSL function so as to preserve compatibility with old scripts implementing their own workaround; or a fix similar to that for XorBase64* is implemented.
  • Monty Linden is “looking into weird bugs and doing a project related to mobile.”
  • Pepper Linden has been carrying out more Conductor work to help with region packing. Pepper has also been engaged in the work on outfits support for the next SL Mobile update.
  • A question was asked on the status of long-discussed possible updates / improvements to in-world Land Impact calculations (such as removing Scale as a factor, as had been most “recently” discussed in SUG meetings). In short: no real progress at this time, due to the issue being somewhat complicated.
    • This led to a conversation on Land Impact, LODs (and LOd decimation) allowing larger megaprims, etc.
  • Also flowing through themeeting was a conversation relating to region sizes, region crossings, water planes, etc.

Date of Next Meetings

  • Leviathan Linden: Tuesday, November 18th, 2025.
  • Formal SUG meeting: Tuesday, November 25th, 2025.
