2026 week #24: SUG meeting summary

The following notes were taken from the Tuesday, June 9th, 2026 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

• Wednesday June 10th should see the Loganberry RC deployed to all RC simulator channels.
• An update to the Lua simulator code is due to appear Soon™.

In Brief

• Rider Linden:
  • Has been on-call this week so most of his attention has been on some old clean-up issues.
  • He has also hunted down a race condition that occurs when you crash and log back in right away, and believes he has a fix in the works for that.
  • He is also due to start a review some of the simulator-side Lua build work, it having been suggested internally that a different approach to some of the work might be preferable.
• Harold Linden (LUA):
  • Has merged the Loganberry simulator code base with the the Lua development branch. This work should include the cross-region collision script failure fixes he’s also been working on, together with his changes to how setprimitiveparams is wrapped.
  • Is still waiting for integers and classes to stabilize upstream (they’re still feature flagged) before he pulls it into the Lua development branch. He does not believe there are any No existing major crashers / blockers noted for Lua in this work, but doesn’t want to endanger that until there’s something worth picking up from upstream.
  • He may still pull in the latest changes even with integers flagged off, since there’s a number of performance-related fixes that LL is behind on.
  • It is believed there are very few crashers left within the Lua code base.
  • Region holders wishing to be on the Lua simulator should submit a support ticket to have their region moved. Note that requests will only be approved if the region is not directly adjacent to any non-lua regions.
• Pepper Linden:
  • Has been working on “a chat-related project” (the Chat Modernisation work?).
  • Has also been looking at a server bug / griefer mode, where you can be spammed by a bunch of conference chats.
• Monty Linden:
  • Gave a heads-up that LL has been working on authorisation functions, and a few people are having log-in problems as a result. Do, if you find your password is not being honoured, it may not be your end of things.
  • Noted that Lua documentation is getting some attention, and there are refinements coming to the collaboration model and processes (Second life Creation portal). Should see some more PR movement soon.

General Discussion

Please refer to the video below for  more on the following.

• A request was made for progress on Can’t teleport or cross borders after certain amount of time in region. While no direct work has been put into this issue as raise, Monty Linden noted that the issue reported in FIRE-35085 is likely a major contributor to the reported problems, and there are probably others.
• The issue where Simulator occasionally halts scripts on region handoff when they have collision and/or llSleep() was the cause of some confusion, with some people believing it had been fixed in the Loganberry simulator update whilst Rider indicated the fix is in the upcoming Mango simulator update.
• Allow custom values for llGetHTTPHeader() was raised, with Rider Linden noting there is a wider look at script HTTP on the drawing board at LL, which will include the current header restrictions. However, this is not in a position to go on the roadmap for implementation at the time of the meeting.
  • This sparked a general discussion on script HTTP.
• Clarification on the use of bots for data-gathering (and where they cross the line) was again requested – and this was redirected towards the upcoming Trust and Safety User Group meetings – see here for more.
• The end of the meeting included a discussion on Ternary and/or Null coalescing operators in Lua (which went right over my head and clean past the wicket keeper…).

Date of Next Meetings

• Leviathan Linden: Tuesday, June 16, 2026.
• Formal SUG meeting: Tuesday, June 23, 2026.
