+
+==Installation==
+
+See the [download page http://www.grammaticalframework.org/download/index.html].
+
+==New features==
+
+- Source language extension: it is now possible to override the oper definitions in an interface, by using the 
+  header syntax ``instance Foo of Bar - [f,g,h]``.
+- New functionalities in GF shell commands (more information with ``help`` command-name).
+  - ``aw`` = ``align_words`` option ``-giza`` prints word alignments in Giza++ format.
+  - ``i`` = ``import`` now recognizes changes in abstract syntax without the need of ``empty``.
+  - ``pg`` = ``print_grammar`` option ``-lexc`` prints lexicon in Xerox LEXC format.
+  - ``ps`` = ``put_string`` now has flags for reading transliteration rules from a user-provided file.
+  - ``r`` = ``reload`` repeats the latest instance of ``import``.
+  - ``sd`` = ``show_dependencies`` shows all dependencies of a constant, and optionally their code sizes.
+  - ``so`` = ``show_operations`` shows the oper's in scope, optionally restricted to a value type.
+  - ``ss`` = ``show_source`` shows source code, or optionally just function headers or source code sizes.
+
+
+- Haskell output as Generalized Algebraic Datatypes: ``gf -make -output-format=haskell --haskell=gadt``
+- ``gf -server`` replaces ``pgf-http`` and makes it easy to test the minibar
+  and the web-based grammar editor.
+- Faster grammar compilation (also included in the GF 3.2.9 source-only
+  snapshot).
