+In the future, core APIs will be updated independently from the core, so all the compatible cores will seamlessly adopt new features.
 This requires support from all the IDEs, so in the meantime we suggest to release the core by copying a snapshot of this `api` folder.
 
 The most elegant and effective solution is to develop the core with `api` symlinked and produce the distributable archive by telling `tar` to follow symlinks.
