Release Notes

End User License Agreement

Why no more installer?

Providing signed Windows installers now requires paying expensive yearly certificates. As EditiX is maintained by a single developer, and with fewer users than before, continuing to pay for those certificates is no longer sustainable.

Instead, EditiX is 100% free and open-source. You build it once using standard Java tools (git + ant), and you get a fully functioning editor with the same features as before.

This ensures:

transparency
long-term access to the code
no hidden dependencies
and a maintained product without subscription or installer fees

Thank you for your understanding and support.

Use the binaries if you don't want to compile EditiX XML Editor yourself.
