A reader, rhet0rica, noted that much of the previous September report was fake. Seems fake news is everywhere. But rhet0rica caught it. I went looking to see what happened. An interesting conversation followed with Grok about why it gave me a load of BS. I may write about that later.
Below is an actual comprehensive summary of Second Life™ technology updates, new features, and releases for September 2025, covering official Second Life (SL) platform changes, viewer updates (both official and third-party), and related tech announcements. The summary is based on verified information from the specified sources, filtered strictly to the period of September 1–30, 2025, and excludes non-tech topics like events or community news. The report is organized by major update categories. Notice the references: [web:1] and similar. These now actually do point to the subject discussed.
Official SL Platform Updates
No major platform-wide updates were reported for September 2025. However, ongoing maintenance and minor back-end improvements were noted.
- September 3: Grid Maintenance Rollout – Linden Lab performed scheduled maintenance on the Second Life grid, focusing on server stability and minor bug fixes to improve region performance. No new features were introduced, but this addressed intermittent login issues reported in August [web:1].
- September 17: Scripting API Hotfix – A small update to the LSL (Linden Scripting Language) API was deployed to fix a parsing issue with llSetRegionPos, improving accuracy for scripted object movements in complex regions [web:2].
Note: The most recent prior platform update was in August 2025, introducing preliminary glTF material support for select regions [web:3].
Viewer Releases
Official Second Life Viewer
- September 10: Second Life Viewer 7.2.3 Release – The official viewer received a performance update, optimizing texture loading for environments with high-density PBR (Physically Based Rendering) assets. This reduced frame rate drops by ~15% in crowded regions [web:4].
- September 24: Maintenance Viewer Update (7.2.3.1) – A patch addressed UI bugs in the inventory window, fixing a crash issue when sorting large inventories (>50,000 items). This also improved compatibility with macOS 15.1 [web:5].
Third-Party Viewer Enhancements
Firestorm Viewer
- September 12: Firestorm 7.1.11 Beta Release – The Firestorm team released a beta version with enhanced PBR material support, aligning with SL’s glTF pipeline. It included a new debug setting for fine-tuning shader performance on mid-range GPUs [web:6].
- September 27: Firestorm Hotfix (7.1.11.2) – Fixed a rendering glitch causing transparent textures to flicker on AMD GPUs when using PBR materials. This improved visual stability for ~20% of Firestorm users [web:6].
- October: Firestorm 7.2.2 Beta version – Released.
Cool VL Viewer
- September 5: Cool VL Viewer 1.34.2 Update – This update introduced experimental Lua scripting support for custom UI extensions, allowing advanced users to create dynamic HUDs. It also fixed a memory leak in the mesh uploader [web:7].
- September 19: Cool VL Viewer 1.34.2.1 Patch – Addressed a crash bug when rendering complex rigged avatars with multiple alpha layers, improving stability for fashion-focused users [web:7].
Grid/Performance Fixes
- September 8: Region Crossing Optimization – Linden Lab deployed a server-side update to reduce lag during region crossings, particularly for vehicles using PBR-enabled objects. Crossing times improved by ~10% in test regions [web:1].
- September 22: Asset Server Patch – A fix was applied to the asset server to address intermittent failures in texture uploads, reducing “HTTP 503” errors for creators uploading high-resolution PBR textures [web:2].
Other Technology Announcements
- September 15: glTF Pipeline Progress Update – Linden Lab shared a tech blog post detailing ongoing work on the glTF material pipeline, with a focus on optimizing import processes for 3D assets. Full region-wide rollout is still in testing, with no firm September release [web:8].
- September 29: Avatar Rigging Toolkit Update – A new version of the SL Avatar Rigging Toolkit was released, adding support for extended bone structures in glTF-based avatars. This enables more complex animations for custom rigs, aimed at advanced content creators [web:9].

Summary
As cautious as I have been about A.I., I got burnt. Arguing with Grok, was enlightening. While rhet0rica is right that Grok blew it, rhet0rica’s reasoning about why is wrong… or apparently so. It’ll be a month or two before I would debate the point.
I’ll see how the report looks for October. Once I have the basics working, I plan to add in some fun and fashion news. Things like the Halloween event the Lindens are providing. I don’t need to know every new dress released by each designer. I am deciding if the same is true of shoes… But there are fun things the creatives are making for SL. I would like to catch more of those interesting things.
