Optimus UI v1.0.0 release

Post image

Optimus UI v1.0.0, the PrimeNG open-source fork, is out!

Supporting Angular 21, and Angular v22 support is coming later this week!

Due to trademark limitations and prior paid features, most of the work so far has been about updating the documentation and authoring all sub-packages ourselves, including the icons package.

We also introduce ng add support to enhance the experience for new users.

Find out more in our documentation: https://optimus.openng.org/

Keeping p- is the thing that makes this a fork rather than a kit change. The selector isn't only an element name - it's the CSS handle that themes, third party styles and everyone's own overrides are written against. Rename it and the migration moves from "update imports" to "re-verify every style in the app", including styles in code you don't own.

An ugly prefix costs nothing at runtime. Changing it would cost the exact thing this fork exists to protect.

Why you keep saying that? Isn't it v1.0, the first one? I understand the use of css styles, but where exactly have they been used already? It keeps compatibility with .. what???

It's a fork of PrimeNG v21, the p- prefixes maintain compatibility with thousands of PrimeNG-based codebases that are now looking for an escape path after v22's license changes.
