-## Stability Note
-
-This specification has matured over the past several years, and is used in 
-[numerous production deployments](https://stacindex.org/catalogs). 
-With the 1.0.0 release, implementors should expect that most definitions will remain 
-stable. Our goal
-is to maintain backwards-compatiblity within the core for a long time. 
-The STAC specification follows [Semantic Versioning](https://semver.org/), so once 
-1.0.0 is reached, any breaking change will require the spec to go to 2.0.0.

 merge `dev` in to `master`. So `master` should be stable at any given time.
