Ann: SWI-Prolog 7.1.8

Hi,

I have uploaded SWI-Prolog 7.1.8 a few days ago (forgot the
annoucement). There are quite a few changes, but no big stuff.
Highlights:

   - Stabilising Pengine interfaces, additions to whitelisted safety
     analysis.
   - RDF libraries: added n-quad support, drop #fragment when constructing
     a graph name from a URL.  Updated some format-guessing rules.
   - SGML/XML/HTML parser: fixed crash when running the XML parser on an
     HTML5 document.
   - Quite a few documentation updates at various places.

	Enjoy --- Jan


========================================
SWI-Prolog Changelog since version 7.1.7
========================================

  * ADDED: ord_selectchk/3.  Nicos Angelopoulos (ask) & Richard O'Keefe
    (provide).

  * ADDED: library(sandbox): support for format/2,3 and debug/3.

  * FIXED: Item#671: arg(1000000000000000000,s(_),_) should fail.
    Ulrich Neumerkel.

  * DOC: Deal with version 6/7 issues in docs of phrase.  Fixed after
    comments from Michael T. Richter.

  * ADDED: clause_property(Clause, SizeInBytes)

  * ADDED: library(prolog_format) for analysing Prolog format
    strings. Contributed by Michael Hendricks.

  * DOC: Status of strings is no longer unsure.

  * DOC: Be more careful about \verb$<tag>$.  Avoids a lot of \bnfmeta{}{}
    in the generated web pages.

  * DELETED: library(wise).  Used to support the Wise solutions Windows
    installer. This installer no longer exists and SWI-Prolog switched
    to NSIS long time ago.

  * ENHANCED: Allow double declarations for a setting, provided both name,
    type and default are the same.  Simplifies moving settings between
    libraries that are part of different source trees.

  * ADDED: peek_string/3, providing long look-ahead to facilitate guessing
    the content type from data on (HTTP) streams.

  * DOC: More on select/4

  * MODIFIED: Use =backtrace_show_lines= flag to derive the default for
    subgoal_positions(Boolean) in print_prolog_backtrace/3.

  * DOC: select/4.  Abramo Bagnara.

  * FIXED: Prevent colour handling from failing on a meta-called
    list. Wouter Beek.



==============
Package debian
==============

  * ADDED: library(pengines) to the Ubuntu PPA builds

  * FIXED: SO_PATH patch to avoid -rpath

  * DELETED: Java library path for testing patch.  This patch is now
    generalised and applied to the base system.

  * ADDED: library(pengines) to the Ubuntu PPA builds


============
Package http
============

  * UPDATED: library(mimetype): Mime type for Turtle, added n-triples
    and nquads.

  * ADDED: setting http:prefix to library(http/http_path).  Fixes
    undocumented dependencies on ClioPatria.

===============
Package ltx2htm
===============

  * ADDED: \nodcgref{name}{arity}

================
Package pengines
================

  * FIXED: pengine_pull_response/2 was not yet updated for UUID based
    pengine representation.

  * DELETED: Most option-less versions of the pengine_* predicates.

  * MODIFIED: Made pengine_send/2 and pengine_send/3 private.

  * FIXED: pengine_rpc/3: avoid operator issues between client and server.

  * ADDED: JavaScript class Pengine now accepts server: string to define
    the location of the server.

  * ADDED: Send errors to console.error if there is no onerror handler
    and there is a console.

  * ADDED: pengine_debug/1

  * FIXED: Continue main loop if ask fails due to an unsafe goal.

  * FIXED: Terminate if option processing fails.

  * ENHANCED: Throw existence_error when sending to a non-existing
    pengine. Make pengine_destroy/1 succeed silently if the pengine
    has gone.

=============
Package pldoc
=============

  * ENHANCED: Use /pldoc/man?section=<ID> for section(ID) object HREF.


==============
Package semweb
==============

  * ADDED: library(semweb/rdf_ntriples): Support nquads format.

  * DELETED: rdf_db:rdf_input/3 hook that was used by old ClioPatria
    versions. Please upgrade ClioPatria if this hits you.

  * MODIFIED: rdf_load/2: default graph for loading RDF from an URL now
    normalizes the URL and removes a possible #fragment.  This ensures
    that rdf_load/2 for e.g., skos:Concept and skos:prefLabel load the
    same graph.

  * DOC: rdf_load/2 updates

  * MODIFIED: Load a TRiG file into a single graph if the format =turtle=
    is explicitly specified.

============
Package sgml
============

  * DOC: \verb$ error

  * ENHANCED: Added type checking on element content instead of using
    assertion/1.  Alan Baljeu.

  * FIXED: Crash when loading implicit DTD.  Occurs when loading HTML5
    using load_xml/3.

=================
Package swipl-win
=================

  * FIXED: Avoid getting SWI-Prolog.app inside SWI-Porlog.app

============
Package xpce
