 # Docusaurus 2 Changelog
 
 ## Unreleased
-- More efficient hot reload & consistent generated file. 
-- Set babel `compact` options to `true` which removes "superfluous whitespace characters and line terminators.
-- Skip fileHash caching on production calculation to improve build performance. The runtime cache is only useful in development.
-- Obtain git timestamp for `showLastUpdateAuthor`/ `showLastUpdateTime` asynchronously instead of synchronously. This improves build performance greatly.
