Polished and renamed release notes to release-3.6.t2t
Also added an example use of lookupmorpho to gf-web-api-examples.html.

Also, alternate character encodings should now be specified + as ``--# -coding=``//enc//, instead of ``flags coding=``//enc//. + See the separate document + [GF character encoding changes encoding-change.html] for more details. +- Record update: in record objects (but not types) of form ``r ** s``, the values assigned + in ``s`` now overwrite those in ``r``. In previous versions, record extensions with + overlapping assignments in ``r`` and ``s`` were not supported, and their behaviour was + unpredictable. +- The PGF file format has changed in minor but backward incompatible ways. + GF can still read the old format, thanks to a backward compatibility + module. The C run-time system supports only the new format. Old PGF files + can be converted to the new format by loading them in the GF shell and + writing out a new PGF file with the ``pg -pgf`` command. +- The PGF run-time Haskell library includes some new modules, e.g. + ``PGF.Lexing`` which contains lexing and unlexing functions, and + ``PGF2``, which is a binding to the C run-time system. The latter is included + only if GF is configured with ``-fc-runtime``, which is not the default, + since the C run-time system still has to be compiled and installed + separately before installing GF. The binary packages for GF 3.6 available + from the download page will include C run-time support. +- ``nonExist`` now exists. It can be used in concrete syntax to mark + non-existing morphological forms. +- Token gluing: ``BIND`` and ``SOFT_BIND`` can be used in concrete syntax to + mark that the surrounding tokens should not be separated by space. +% - Unicode characters in identifiers [...] (not documented, not tested) + + +====Bug fixes and minor changes==== + +- Nonlinear patterns (i.e., patterns where the same variable appears more than + once) in concrete syntax are now detected and reported as errors. + (Section C.4.13 in the GF book states that patterns must be + linear.) +- A pattern matching bug which prevented variables in patterns to be bound to + table values has been fixed. +- A bug with local variable name shadowing has been fixed. +- Type checking fixes: correction of + subtyping check for ``Ints n<=Ints m`` and contravariance in table types. +- The refresh pass +% (and thus the command line option --dump-refresh) + had become obsolete and has been removed. +- The old partial evaluator + (and thus the command line options ``--new-comp`` and ``--old-comp``) + has been removed. +- A missing rewrite rule has been added to the partial evaluator. It + can significantly reduce the compilation time for certain grammars. +- Some additional datestamp checks have been added to ``gf -make`` to avoid + recreating a PGF file when an uptodate PGF file already exists. +- The ``--output-dir`` option now applies also to PGF files. + +===Resource Grammar Library=== + +- New languages in the Resource Grammar Library: Estonian + (see the [updated synopsis ../lib/doc/synopsis.html]). +- Grammars and dictionaries for wide coverage translation [source ../lib/src/translate/] +- bug fixes and some new inflection paradigms in many languages +% - [...] + + +===GF Cloud services=== + +- There is a preliminary new [Wide Coverage Translation Demo http://cloud.grammaticalframework.org/wc.html] web app. The same wide coverage translation + method has also been added to the + [Simple Translation Tool http://cloud.grammaticalframework.org/translator/]. +- PGF web service API: + - the ``lookupmorpho`` request has been added to lookup the morphological + analysis of a word. + - Requests like ``parse`` and ``translate`` that parse text input now + accept a ``lexer`` parameter to apply a lexer to the input text before + parsing. The lexer can be ``text``, ``code`` or ``mixed``. + - Requests like ``linearize`` and ``translate`` that produce + linearizations now accept an ``unlexer`` parameter to apply an unlexer to the + linearizations. The unlexer can be ``text``, ``code`` or ``mixed``. + - Preliminary new requests to access the C run-time system have been added: + - ``c-parse``, ``c-linearize``, ``c-translate``, ``c-lookupmorpho``, + ``c-grammar``. These work in the same way as the corresponding requests + without the ``c-`` prefix. Since the ``c-parse`` and ``c-translate`` can + produce very many (even infinitely many) results when used with large + ambiguous grammars, using the ``limit`` parameter to restrict number of + results, e.g. ``limit=10``, is recommended. + - ``c-wordforword``: this works as ``c-translate`` but does a + word-for-word lookup to create a (potentially very low quality) + translation that can be used if all else fails. + + +-------------------- + +[www.grammaticalframework.org http://www.grammaticalframework.org] |
