- Technical Specs: WebRTC enables peer-to-peer connections for improved reliability; supports spatial audio and group voice channels. Fixes Vivox issues like echo across regions and device detection problems.
- Community Feedback: Testing emphasizes stability in high-traffic areas; early reports note smoother transitions during sim crossings. Full rollout expected post-beta, with backward compatibility for Vivox regions during transition.
- Impact: Addresses long-standing voice complaints; aligns with mobile app integration. More details in SL Community Blog; opt-in via estate tools.
Marketplace Subscription and Listing Enhancements Issue – Resolved August 26, 2025
- Bug Fix and Monitoring: Reports of Marketplace subscriptions and listing enhancements failing were investigated and fixed. Users advised to double-check settings, as some reverted during the patch.
- Technical Details: Involved backend stability for auto-renewals and premium listings; fix implemented without downtime. Ongoing monitoring for edge cases like disabled enhancements.
- Impact: Improves reliability for creators relying on Marketplace for income; part of broader web platform optimizations. Status update via SL Grid Status blog.
Scheduled Server Maintenance and Rolling Restarts – August 26-27, 2025
- Main Grid Restarts: Rolling restarts on August 26 (starting 6:00 AM PDT) for stability updates; no-copy objects not recommended during process. RC channels restarted August 27 (7:00 AM PDT).
- Unscheduled Maintenance: Billing phone lines and live chat support maintenance on August 30; feedback portal maintenance on August 21.
- Technical Focus: Aimed at performance tweaks, including post-PBR optimizations and WebRTC prep. No major new features, but ensures grid reliability.
- Impact: Minimal disruption; users reminded to save builds. Part of routine infrastructure work supporting viewer updates. Details on status.secondlifegrid.net.
Support Team Expansion Progress – Update August 2025
- Backlog Reduction: Expanded team closing tickets faster; urgent issues prioritized. Internal systems improved for smoother operations.
- Technical Context: Addresses higher ticket volumes from viewer updates (e.g., PBR, glTF) and mobile beta. New staff names appearing in responses.
- Impact: Faster resolution for tech issues like crashes or rendering bugs. Ongoing from July; full normalization expected soon.
Third-Party Viewer Updates
