v1.00.20Released Jun 23, 2026 (1mo ago)
Patch 1.00.20 — Steam Market Launch Schedule
- Steam Market reopening announced for 2026-06-25
- Top three grades restricted initially
- Security vulnerability patched
Patch 1.00.20 is a schedule-anchor hotfix. The Market launch window was set for 2026-06-25 00:00 PDT, with the same Cosmic / Divine / Celestial restriction that 1.00.21 would formalise. The security fix is intentionally unspecific in the public changelog — it patched an undisclosed exploit chain rather than a single item.
