Dylan is an advanced, object-oriented, dynamic language which supports rapid program development. When needed, programs can be optimized for more efficient execution by supplying more type information to the compiler. Nearly all entities in Dylan (including functions, classes, and basic data types such as integers) are first class objects. Additionally Dylan supports multiple inheritance, polymorphism, multiple dispatch, keyword arguments, object introspection, macros, and many other advanced features... --Peter Hinely
C3 superclass linearization 2012-01-25
We implemented the C3 superclass linearization algorithm and enabled it by default. This is more intuitive and will allow for further performance improvements.
Dswank - emacs and DIME 2011-12-12
We developed DIME, the Dylan interaction mode for emacs, based on SLIME. Now, you can browse the class hierarchy, get argument lists, locate definitions, compile, view warnings and more, all from within emacs!
New release: 2011.1 2011-12-10
We just released Open Dylan 2011.1. This release is our first since moving to GitHub and relicensing under a more liberal license. It brings many bugfixes, inmproved platform support and new features.
For more on the background and goals of the Dylan language, see the excellent Introduction to the Dylan Reference Manual.
