[issue tracker https://github.com/GrammaticalFramework/GF/issues],

===GF compiler and run-time library===


====New features and notable changes====

- Support for language-specific depencency configurations (in addition to abstract syntax based ones); see ``help vd`` in the GF shell

- An experimental support for sentence lookup which makes it possible
to find the sentence from the grammar that matches best a set of keywords.
Right now it is usable only with controlled languages since it might be
very innefficient for some grammars.

- A new .NET binding for the GF runtime is available.

- The API in the Java binding is extended and it covers more from
the full functionality of the C runtime.
