Overview
- Sony issued a phased PS5 system software update on June 4, 2026 that appears as version 26.04-13.40.00 and downloads at roughly 1.2 GB.
- Official patch notes simply state the firmware has “improved system software performance and stability,” with no user-facing feature list.
- Reporters who installed the update found no sign of the streamlined home UI that Sony tested in April and later reverted.
- Coverage notes small inconsistencies in the version string reported by outlets and confirms the rollout is phased with at least the UK receiving the file.
- Observers say the update likely contains security hardening or backend changes and may include limited stealth tweaks to the PlayStation Store while Sony prepares any future public UI or feature releases.
