MSFS News Roundup: May 15–21, 2026 — SU5.1, PMDG, GSX Pro 4
SU5.1 beta lands to fix console crashes, PMDG finishes the 737NG overhaul, FlyByWire splits 2020 and 2024 builds, GSX Pro 4.0 ships, plus more.
Microsoft Flight Simulator 2024 ships sim updates, world updates, and developer patches on a moving cadence, and most beginners only find out when something breaks. This pillar is the curated weekly index — every Friday roundup, every patch-note explainer, and the standalone breaking-news posts we publish when something important drops.
/news/yyyy/mm/.Coming soon. Patch-note explainers will live under this cluster as Microsoft and Asobo ship sim updates.
The News Desk monitors:
A weekly roundup ships every Friday at 14:00 UTC, plus standalone breaking-news posts within 4 hours of confirmed major events such as a new sim release, a major outage, or a high-impact world update.
Primary sources only — Microsoft Flight Simulator Insider, Asobo Studio dev blogs, official developer channels for PMDG, Fenix, iniBuilds, and FlyByWire, plus the moderated r/flightsim and r/MicrosoftFlightSim subreddits. Every claim in a roundup links to its primary source.
No, not in the first 90 days. Flight Sim Workshop is MSFS-first until our coverage is the definitive English-language resource for that platform.
