The Lua Editor Alpha Viewer takes another important step toward a more capable scripting workflow in Second Life. This release improves communication between the Viewer and the newly published Second Life VS Code extension, restores an experimental Linux Viewer, and includes the latest WebRTC Voice and viewer-maintenance updates.
This may be the final Lua Editor Alpha before the work moves into the 26.4 Beta Viewer, so we would especially value feedback from scripters, creators, and Linux users.
The Lua Editor integration now provides a smoother, more reliable workflow between Second Life and Visual Studio Code.
These improvements accompany the Second Life VS Code extension and its tighter integration with the Viewer. The related Viewer work is documented in PR #6104 and PR #6156.
The Viewer continues to support both LSL and Lua scripts, including language-specific syntax information supplied by supported regions.
For information about using Lua in Second Life, visit the Lua Alpha wiki page.
An experimental Linux build of the Second Life Viewer is available again with this release.
This work brings the Linux Viewer back onto the current Viewer codebase and incorporates the 26.3 maintenance changes. As this remains an early return for official Linux builds, Linux users should expect some rough edges and are strongly encouraged to report compatibility, installation, graphics, audio, and input issues.
The integration work can be found in PR #6132.
The Linux build may be downloaded directly from GitHub https://github.com/secondlife/viewer/releases/download/Second_Life_Project_Lua_Editor%23f26e024-2026-08-20/Second_Life_Project_Lua_Editor_26_3_0_32302693173_x86_64.tar.xz
