GF 3.9 Release Notes
August 2017

==Installation==

See the [download page http://www.grammaticalframework.org/download/index.html].


==What's new==

The [GF  repository on GitHub https://github.com/GrammaticalFramework/GF/]
is now our master source repository, not just a read-only mirror.
Bug reports and feature requests can be submitted to the
[issue tracker https://github.com/GrammaticalFramework/GF/issues],
and we also accept pull requests.

Over 200 changes have been pushed to the source repository since
[the release of GF 3.8 release-3.8.html] in June 2016.


===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.


====Changes of interest to compiler developers====

- The compiler source code has been updated for compatibility with GHC 8.2.1.


===Resource Grammar Library===

- New languages:
  - Icelandic
  - Norwegian Nynorsk


- API now usable for incomplete languages via ``Missing`` modules:
  implemented for Arabic and Latin.
- Punctuation with ``BIND`` and ``SOFT_BIND`` tokens for a number of languages


- Various fixes for several languages.

- Various fixes in the translation dictionaries.


===Apps and Cloud services===

- PGF service: support for language-specific depencency configurations in
  ``command=deptree``.
