Europa Universalis 5 patch 1.3 appears to be targeting a full stable release about four to six weeks after the open beta began on June 4, 2026 , which points to early-to-mid July 2026 as the likely window. GameWatcher also lists the release as June/July 2026 rather than a fixed day, so that date still looks tentative.

What’s known

  • The 1.3 open beta went live on June 4, 2026.
  • The developer’s stated target was to bring 1.3 to full release within four to six weeks of the beta opening.
  • That means the stable version would most likely land sometime between July 2 and July 16, 2026 , if the plan holds.

Practical read

This is still a moving target, because beta feedback can push a release back if the update needs more tuning. For now, the safest answer is: expect stable 1.3 in July 2026, likely early to mid-July.

TL;DR: Patch 1.3 stable is expected around early-to-mid July 2026, not on a confirmed exact date yet.
