Yumma CSS 3.8

Transition of the Yumma CSS ecosystem to a monorepo for improved development coordination.

Yumma CSS 3.8

Monorepo transition

The Yumma CSS ecosystem has transitioned to a monorepo. The api, nitro (the Yumma CSS engine), & runtime now reside in the main yummacss repository.

This consolidation improves development efficiency & ensures package synchronization.

Public archives

Repositories for API, Nitro, & Runtime are now archived. Future development occurs in the main monorepo.


Version synchronization

Core package versions are synchronized with the main Yumma CSS version:

  • @yummacss/api@1.8.0 -> @yummacss/api@3.8.0
  • @yummacss/nitro@0.5.0 -> @yummacss/nitro@3.8.0
  • @yummacss/runtime@0.3.0 -> @yummacss/runtime@3.8.0

No API changes

This update is a structural change. Existing functionalities, bug fixes, & usage patterns remain unchanged.
