This is a significant minor release with
Ceylon's powerful flow-sensitive static type system catches many bugs while letting you express more, more easily: union and intersection types, tuples, function types, mixin inheritance, enumerated types, and reified generics.
We spend more time reading other people's code than writing our own. Therefore, Ceylon prioritizes readability, via a highly regular syntax, support for treelike structures, and elegant syntax sugar where appropriate.
Ceylon controls complexity with clarity. The language eschews magical implicit features with ambiguous corner cases. The compiler follows simple, intuitive rules and produces meaningful errors.
Modularity is at the very core of the language, SDK, and tooling. The compiler produces module archives which are then distributed via a next-generation repository architecture with Ceylon Herd as its social focus point.
Static typing is the technology that enables killer tools. Ceylon comes with a complete command line toolset, and an awesome Eclipse based IDE with searching, refactoring, quick fixes + assists, autocompletion, debugging, and much more.
