v4Umbra
Introducing Evorion 4
Stronger server-side security, sharper tamper detection, and clearer failure signals across the platform.
What shipped in Evorion 4 Umbra
Umbra is a security and reliability release on top of Denali. Server-side authorisation is signed end to end, tamper detection was rewritten around a self-verifying integrity mesh, transport was hardened across every request path, and every server rejection now surfaces the exact reason your client needs to react. Windows 11 24H2 is supported natively, false-positive integrity trips on real launcher environments are gone, and the developer panel has been polished throughout.
