v4.0.0

TypeScript *.d.ts type definition files are now bundled with both Derby and Racer!

derby@4 uses racer@2. If you have a separate dependency on Racer, be sure to update it.

Breaking changes

• Declaring a singleton component via ComponentClass.prototype.singleton = true; is no longer supported.
  • Instead, use a static property class ComponentClass { static singleton = true; }
  • Or without class syntax, ComponentClass.singleton = true;
• Internal class hierarchies have been changed, with new client-specific and server-specific classes inheriting from base classes.
  • This generally won't affect you, unless you had custom type definitions written for Derby's classes.
  • In most cases, the base class type is appropriate unless you are using specific client or server side methods
    • Derby base, DerbyForClient and DerbyForServer subclasses
    • Page base, PageForClient and PageForServer subclasses
    • App base, AppForClient and AppForServer subclasses

If you are upgrading straight from the pure-JS derby@2, also see the release notes for derby@3 here:
