Parses new syntax: BINDINGS, isNUMERIC(), MINUS, sub SELECT and
SERVICE.
The syntax format for parsing data graphs at URIs can be explictly
declared.
The roqet utility can execute queries over SPARQL HTTP Protocol and
operate over data from stdin.
Added several new APIs
Fixed Issue: #0000388

Added XSD Date comparison support
Support building with Raptor V2 API if configured with --with-raptor2.
Many other bug fixes and improvements were made.
Fixed Issues: #0000352, #0000353, #0000354, #0000360, #0000374,

Lesson learnt: do not commit code after midnight local time.

Add initial draft parsing and API (NOT execution) support for SPARQL
1.1 Update W3C Working Draft of 2010-01-26.
Add public APIs (row, results, result formatter, variables table) so
that query results can be built, read and written without a query.
Add API resilience checks for invalid NULL pointer arguments.
Many other bug fixes and improvements were made.
Fixed Issues: #0000320, #0000323#0000343, #0000345 and #0000347
2009-12-16 Rasqal Version 0.9.17 Released
WARNING: ABI AND API CHANGED in this release. Rasqal 0.9.17 is binary

Added a new query engine that implements the SPARQL algebra better
All constructors now take a rasqal_world argument
Added LAQRS syntax support for SUM, AVG, MIN, MAX, COALESCE()
experimental syntax
Added query result formatters for CSV, TSV and ASCII tables
Prefer pkg-config for configuring
Many resilience and resource failure fixes by Lauri Aalto
Many other bug fixes and improvements were made
Fixed Issues: Issue#0000077, Issue#0000128, Issue#0000168,
Issue#0000258, Issue#0000261, Issue#0000271, Issue#0000279 and
Issue#0000305
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
2008-07-05 Rasqal Version 0.9.16 Released
WARNING: ABI AND API CHANGED in this release. Rasqal 0.9.16 is
incompatible with 0.9.15.
Added a rasqal_world object used for all constructor functions
Removed deprecated functions and macros
Fixed some memory leaks and made some low-memory resiliance fixes
Query result sets can be read/written from sparql XML results format
Improved error syntax error reporting
See the Raptor 0.9.16 Release Notes for the full details of the
changes.
Rasqal is a free software / Open Source C library that handles
Resource Description Framework (RDF) query syntaxes,
query construction and query execution returning result bindings.
The supported query languages are SPARQL and RDQL.
