</ul>
<h3>General changes</h3>
<p>
Requires <a href="http://librdf.org/raptor/">Raptor</a> 2.0.7 or newer<br />
</p>
<h3>Model class changes</h3>
<p><code>librdf_model_contains_statement()</code> now returns > 0
only for invalid statements according to the API contract.
NULL statements are considered invalid.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=489">Issue #0000489</a>
</p>
<h3>Node class changes</h3>
<p>All the constructors now normalize the nodes (Raptor terms) so
that equality is a cheap pointer comparison.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=443">Issue #0000443</a>.
</p>
<h3>Query class changes</h3>
<p><code>librdf_query_results_get_binding_value()</code> and
<code>librdf_query_results_get_binding_name()</code> now fail when
called with negative offsets.
</p>
<h3>Serializer class changes</h3>
<p>Serializing (using Raptor) now sets the statement graph field to
make serializing to N-Quads work.
</p>
<h3>Storage class changes</h3>
<p>Loading the same storage multiple times no longer gives a runtime
error.</p>
<p><code>librdf_storage_contains_statement()</code> now returns >
0 only for invalid statements according to the API contract. Uses
<code>librdf_statement_is_complete()</code> for testing statement
validity.
</p>
<p>hashes storage: Make matching a statement work when using graph
names (redland contexts).
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=515">Issue
#0000515</a>
</p>
<p>mysql storage: Defaulted storage configuration host to 'localhost'
if it is not given. Opening a store with missing configuration now
reports the required keys.
</p>
<p>postgres storage: Fixed a bad malloc result test during query
allocation that probably caused
<code>librdf_model_find_statements()</code> to fail. Fix from
'zoggy' on github - thanks. Made loading triples from a stream to
postgresql actually work via
<code>librdf_model_add_statements()</code>. Defaulted storage
configuration host to 'localhost' if it is not given. Opening a
store with missing configuration now reports the required keys.
</p>
<h3>Unicode module changes</h3>
<p>Added <code>librdf_latin1_to_utf8_2()</code> with size_t args.
Deprecates librdf_latin1_to_utf8().</p>
<p>Added <code>librdf_utf8_to_latin1_2()</code> with size_t args and
new default arg for replacing out of range characters. Deprecates
librdf_utf8_to_latin1().</p>
<h3>World class changes</h3>
<p>Added <code>librdf_world_set_raptor_init_handler()</code> and
<code>librdf_world_set_rasqal_init_handler()</code> methods to set
handlers for configuring internal raptor and rasqal after they have
been constructed but before they are initialized; before
<code>raptor_world_open()</code> or <code>rasqal_world_open()</code>
are run, respectively. Added new typedefs
<code>librdf_raptor_init_handler</code> and
<code>librdf_rasqal_init_handler</code> for the handlers.
</p>
<h3>Other API changes</h3>
<p>Added <code>librdf_license_string</code> and
<code>librdf_home_url_string</code> static strings to public API
following Raptor and Rasqal naming convention.
</p>
<h3>Other changes</h3>
<p>No longer gives an error when the same storage module is attempted
to be loaded more than once. This is a harmless error and can be
generated by installations that include the shared library storage
module in a '.so' file and the '.la' file associated with it.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=460">Issue #0000460</a>
</p>
<p>Multiple fixes for newer GCC warnings.</p>
<p>Multiple internal fixes for signed int conversions especially
around size_t and allocation.</p>
<p>Removed old debugging memory allocation options
<code>--with-dmalloc</code> for dmalloc and
<code>--with-memory-signing</code> for internal signing of memory
blocks. Valgrind and static analyzers replace this.
</p>
<p>Multiple portability fixes for building out of the source tree.
Out of source tree 'make check' and 'make dist' should both work.
Thanks to Daniel Richard G. for the patches.
</p>
<p>Multiple internal error path cleanup issues and int/size_t issues
found via clang static analyzer.</p>
<p>configure now looks for Oracle DB (aka Sleepycat DB aka Berkeley
DB) 5.3</p>
<p>autogen.sh now supports the NOCONFIGURE variable like
Lib{XML2,XSLT}, aborts the run if an progrma fails and creates the
NEWS if it does not exist to aid building from GIT and 'make dist'.</p>

<h3>General changes</h3>
<p>Added new API functions <code>librdf_alloc_memory()</code>,
<code>librdf_calloc_memory()</code> and <code>librdf_free_memory()</code>
to allow freeing memory allocated inside librdf shared library, such
as on windows with DLLs. (Lauri Aalto)
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=475">Issue #0000475</a>
</p>
<h3>Hash class changes</h3>
<p>Export <code>librdf_new_hash()</code> to the public API.
</p>
<p>BDB Hash now uses the newer 7 args open form in preference to the 6 args
form. (Peter O'Gorman / pogma).
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=468">Issue #0000468</a>
</p>
<h3>Statement class changes</h3>
<p>Reverted <code>librdf_new_statement_from_statement()</code> to the
pre-<code>raptor_term</code> deep copy contract for the function.
(Lauri Aalto)
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=478">Issue #0000478</a>
</p>
<p>Added <code>librdf_new_statement_from_statement2()</code>
providing a shallow copy of statement which was the
post-<code>raptor_term</code> semantics of
<code>librdf_new_statement_from_statement()</code>.
(Lauri Aalto)
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=478">Issue #0000478</a>
</p>
<h3>Storage class changes</h3>
<p>Virtuoso storage:</p>
<ul>
<li>Added switch for VIRTUOSO_DV_TIMESTAMP_OBJ.</li>
<li>Prevent virtuoso query being registered twice in non-modular build
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=461">Issue #0000461</a>.

librdf_free_memory to ensure memory is allocated correctly across
libraries (DLLs). (Lauri Aalto).
</p>
<p>Several code style changes were made.
</p>
<h2 id="rel1_0_14"><a name="rel1_0_14">Redland 1.0.14 Changes</a></h2>
<p>Rasqal minimum version is now 0.9.25 for the new
<code>rasqal_world_get_query_language_description()</code> function.
</p>
<p>Issues Fixed:</p>
<ul>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=">Issue #0000375</a>: Add functionality to parse from iostream (or similar)</li>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=">Issue #0000418</a>: SQLite driver adds duplicate statements if a conext is given.</li>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=">Issue #0000432</a>: Seg fault when getting a blank node after parsing RDF</li>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=">Issue #0000447</a>: fatal error: rdf_types.h: No such file or directory</li>
</ul>
<h3>Hash Class Changes</h3>
<p>BDB Hash (name 'bdb'): Add checks for Oracle Berkeley DB 5.1, 5.0
and 4.9 and updated <code>configure</code> messages with the new
name. The 5.x storage has the same API but has a new on-disk format
that will require a use of the <code>db-upgrade(1)</code> utility in
the utils directory.
</p>
<p>Fixed <code>librdf_hash_get_as_boolean()</code> 'false' string
fixed to actually be a False value.
</p>
<h3>Node Class Changes</h3>
<p><code>librdf_node_write()</code> is defined to now always write
N-Triples format.</p>
<p>Blank node ID generation and mapping from parsing is now
consistently made across Redland librdf rather than relying on some
Raptor defaults.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=432">Issue #0000432</a>
</p>
<p>Fixed URI reference leak in
<code>librdf_new_node_from_uri_local_name()</code>
and
<code>librdf_new_node_from_normalised_uri_string()</code>
constructors.
</p>
<h3>Parser Class Changes</h3>
<p>Do not report programmer errors via logging, just runtime
errors.</p>
<p>Added
<code>librdf_parser_parse_iostream_as_stream()</code> and
<code>librdf_parser_parse_iostream_into_model()</code>
from patch by Norman Gray with style fixes by Lauri Aalto. Thanks.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=375">Issue #0000375</a>
</p>
<h3>Query Class Changes</h3>
<p>Added <code>librdf_query_language_get_description()</code> to
return the full description of of the query language. Deprecates
<code>librdf_query_languages_enumerate()</code>
</p>
<h3>Statement Class Changes</h3>
<p>Restored <code>librdf_statement_decode_parts()</code> to the
public ABI/API which was accidently removed. It has been deprecated
for <code>librdf_statement_decode2()</code> for some time and now
always fails.
</p>
<h3>Storage Class Changes</h3>
<p>Storage Hashes (name 'hashes'): Fixed a reference leak and shared
values issue when cloning a storage. The BDB hash type (current
default) was updated for Oracle DB 5.1; see above.
</p>
<p>Storage SQLite (name 'sqlite'):
Do not add duplicate statements if a context is given.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=418">Issue #0000418</a>.
Fixed a librdf_node reference leak when serializing model with context nodes.
</p>
<h3>UTF8 Module</h3>
<p>Made functions that were already declared in a public header file
and documentation into part of the API.
</p>
<p>Added but deprecated for Raptor equivalents (they are wrappers for them):</p>
<pre>
int librdf_unicode_char_to_utf8(librdf_unichar c,
unsigned char *output, int length);
int librdf_utf8_to_unicode_char(librdf_unichar *output,
const unsigned char *input, int length);
</pre>
<p>Added:</p>
<pre>
unsigned char* librdf_utf8_to_latin1(const unsigned char *input,
int length, int *output_length);
unsigned char* librdf_latin1_to_utf8(const unsigned char *input,
int length, int *output_length);
void librdf_utf8_print(const unsigned char *input, int length,
FILE *stream);
</pre>
<h3>Other Changes</h3>
<p>The internal Redland librdf AVL Tree implementation was removed
and the 'trees' storage changed to use the AVL Tree implementation in
Raptor (<code>raptor_avltree</code>) which is newer and has bug fixes
beyond the Redland librdf version.
</p>
<p>Redland librdf was ran through the
LLVM <a href="http://clang-analyzer.llvm.org/">clang</a> static code
analyzer and several issues fixed, mostly in unused variables and
values computed that were needed but also included a few use of
uninitialized variables especially in error cases. one problem
fixed was in <code>librdf_world_set_feature()</code> to actually set
the value for the genid base and genid counter features
(<code>LIBRDF_WORLD_FEATURE_GENID_BASE</code> and
<code>LIBRDF_WORLD_FEATURE_GENID_COUNTER</code> respectively)
</p>
<p><code>configure</code> now tries harder to find the Oracle
Berkeley DB library using Debian multiarch directories if present.
This is yet another heuristic and rather a hack. For a consistent
approach the <code>--with-bdb</code>, <code>--with-bdb-lib</code>,
<code>--with-bdb-include</code> and <code>--with-bdb-dbname</code>
options to <code>configure</code> should be used.
</p>
<p>Use <code>raptor.h</code> header from Raptor V2.
</p>
<p>Removed Raptor V1 support code as librdf no longer supports Raptor
V1.</p>
<p>Updated RPM spec file to make Redland librdf package require
Raptor V2 (raptor2 package) and Rasqal (rasqal package).
</p>
<p>Add sanity checking when initialising Raptor so that there are
always parsers and serializers, or something went very wrong and
librdf will not work, so return an error.
</p>
<p>Removed internal cache module that no code used, didn't seem to
entirely work and was never in the public API.
</p>
<p>Now configure generates the (untested) win32_rdf_config.h for
(untested) WIN32 builds.
</p>
<h2 id="rel1_0_13"><a name="rel1_0_13">Redland 1.0.13 Changes</a></h2>
<p>Raptor minimum version is now 2.0.0. Raptor V1 support was removed.</p>
<p>Rasqal minimum version is now 0.9.22. Removed use of deprecated
Rasqal functions that were conditioned on older rasqal versions.
</p>
<p>Issues Fixed:</p>
<ul>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=325">Issue #0000325</a>: Make mime_types and syntax URIs available in parser and serialiser enumerations</li>

</ul>
<h3>Node class changes</h3>
<p>Mark <code>librdf_node_to_string()</code> and
<code>librdf_node_to_counted_string()</code> as deprecated.
</p>
<h3>Parser class changes</h3>
<p><code>librdf_new_parser()</code> now logs failure to find a parser
for the given name, type and/or uri rather than just returning NULL.
</p>
<p>Added <code>librdf_parser_get_description()</code> deprecating
<code>librdf_parser_enumerate()</code>.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=325">Issue #0000325</a>
</p>
<h3>Query results class changes</h3>
<p>Added <code>(librdf_query_results_formats_get_description()</code>
deprecating
<code>librdf_query_results_formats_enumerate()</code>.</p>
<p>Removed toy 'triples' query language. Use 'sparql' instead.
</p>
<h3>Serializer class changes</h3>
<p><code>librdf_new_serializer()</code> now log failure to find a
serializer by the given name, type and/or uri rather than just
returning NULL.
</p>
<p>Added <code>librdf_serializer_get_description()</code> deprecating
<code>librdf_serializer_enumerate()</code>.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=325">Issue #0000325</a>
</p>
<p>The graph name is now provided to Raptor serializers so that they
can write out quads, if supported. At present this works with the
'nquads' serializer.
</p>
<h3>Storage class changes</h3>
<p><code>librdf_new_storage()</code>,
<code>librdf_new_storage_with_options()</code> now log failure to
find storage by the given name rather than just returning NULL.
</p>
<h3>Other changes</h3>
<p>Add new generated version defines to librdf.h:
<code>LIBRDF_VERSION</code>, <code>LIBRDF_VERSION_STRING</code>,
<code>LIBRDF_VERSION_MAJOR</code>, <code>LIBRDF_VERSION_MAJOR</code>
<code>LIBRDF_VERSION_MINOR</code> and
<code>LIBRDF_VERSION_DECIMAL</code> (already in earlier versions).
</p>
<p>Removed all code in user build of library that calls abort() and
replaced with an error log, then failure.
</p>
<h2 id="rel1_0_12"><a name="rel1_0_12">Redland 1.0.12 Changes</a></h2>
<p>The main changes in this release are:</p>
<ul>
<li>Enable <code>librdf.h</code> to be used as the top-level header in addition to <code>redland.h</code></li>
<li>Fix linking issues when building with GNU ld with DT_NEEDED disabled</li>

<li><a href="http://bugs.librdf.org/mantis/view.php?id=393">Issue #0000393</a>: librdf_storage_hashes_context_serialise_get_statement</li>
</ul>
<h3>General changes</h3>
<p>The main header file for Redland librdf is <code>redland.h</code>
but some applications used <code>librdf.h</code> direct, which no
longer works in 1.0.11 since some Rasqal symbols were needed.
<code>librdf.h</code> now includes the raptor and rasqal headers and
<code>redland.h</code> is a simple wrapper around librdf.h
</p>
<p>Redland librdf now links with symbols in libraries used indirectly (only
Raptor) to help systems that use GNU ld with a different linking
model to previous versions. This is quite technical and hard to
understand but see Fedora's
<a href="http://fedoraproject.org/wiki/Features/ChangeInImplicitDSOLinking">change in implicit DSO linking</a> and
<a href="http://fedoraproject.org/wiki/UnderstandingDSOLinkChange">Understanding the (Proposed) Change to DSO Linking</a>
that were introduced in Fedora Core 13 released in February 2010.
Redland librdf was packed with patches to fix this, which are now merged
into the sources.
</p>
<h3>Stream Class changes</h3>
<p>Added <code>librdf_stream_get_context2()</code> returning a
<code>librdf_node*</code> deprecating
<code>librdf_stream_get_context()</code> that returns a void pointer.
Fixes
<a href="http://bugs.librdf.org/mantis/view.php?id=392">Issue #0000392</a>.
</p>
<h3>SWIG Bindings Interface</h3>
<p>Export <code>librdf_statement_is_complete</code> to bindings languages.
Fixes
<a href="http://bugs.librdf.org/mantis/view.php?id=329">Issue #0000329</a>
</p>
<h3>Configuration changes</h3>
<p>Rasqal minimum version has been 0.9.19 for some time but is now
enforced in <code>configure</code>.</p>
<p>Updated <code>configure</code> to work with newer autoconf that
enforces <code>AC_LANG_SOURCE</code>.
</p>
<h3>Other changes</h3>
<p>Updated examples to build with Raptor V2 also.
</p>
<p>The node and statement destructors for the Raptor V2 build now
allow NULL pointers like the Raptor V1 versions.
Related to
<a href="http://bugs.librdf.org/mantis/view.php?id=391">Issue #0000391</a>
which had already been fixed for other classes.
</p>
<h2 id="rel1_0_11"><a name="rel1_0_11">Redland 1.0.11 Changes</a></h2>
<p>The main changes in this release are:</p>
<ul>
<li>Virtuoso storage backend querying now fully works</li>

</ul>
<h3>Raptor V2 API support</h3>
<p>This release adds support for building with Raptor V2 API as an
alternate to the Raptor V1 API. When built with Raptor V2 , librdf
uses the Raptor V2 URI, Term and Statement to fully implement the
librdf equivalents. Specifically when this is enabled the following
are typedefed as equivalent:</p>
<ul>
<li><code>librdf_uri</code> = <code>raptor_uri</code></li>
<li><code>librdf_node</code> = <code>raptor_term</code></li>
<li><code>librdf_statement</code> = <code>raptor_statement</code></li>
</ul>
<h3>Configuration and build changes</h3>
<p>Added <code>--enable-raptor2</code> to enable librdf to build with
Raptor V2 API. This requires a rasqal built with Raptor V2 API (with
the <code>--enable-raptor2</code> argument to Rasqal's
<code>configure</code>). The librdf <code>configure</code> will
check that Rasqal was built this way and only enable Raptor V2 API
support if it will work.
</p>
<p>The minimum Raptor version is now 1.4.19 (or Raptor V2 beta 1.9.0+)
</p>
<p>Tests now use the in-memory storage if the BDB (Sleepycat DB)
storage is not available.
</p>
<p>Updated to prevent an error when used with autoconf 2.68+</p>
<h3>Hash Class Changes</h3>
<p>Exposed <code>librdf_hash_from_string()</code> function to public
API for converting from a string to a <code>librdf_hash</code>
object. This is useful for building storage options.
</p>
<p>Added <code>librdf_hash_to_string()</code> function for converting
a <code>librdf_hash</code> back ito a string, intended to be the
opposite of <code>librdf_string_to_hash()</code> and takes a filter
arg to help hide arguments such as 'password'.</p>
<h3>Log Class Changes</h3>
<p>Added a <code>LIBRDF_FROM_RAPTOR</code> log facility.
</p>
<h3>Model Class Changes</h3>
<p>Added <code>librdf_model_write()</code> deprecating
<code>librdf_model_print()</code> debug routine.
</p>
<h3>Node Class Changes</h3>
<p>Added <code>librdf_new_node_from_counted_uri_string()</code>
to make an RDF node from a URI string and length avoiding a <code>strlen()</code>.
</p>
<p>Added <code>librdf_node_get_counted_blank_identifier()</code>
to return ID with length.
</p>
<p>Added <code>librdf_new_node_from_counted_blank_identifier()</code>
with counted ID string.
</p>
<p>Added <code>librdf_node_new_static_node_iterator()</code> with
world arg added deprecating
<code>librdf_node_static_iterator_create()</code> without it.
</p>
<p><code>librdf_node_write()</code> added to write a redland node to
an iostream, formatted as N-Triples.</p>
<p>Adjusted <code>librdf_node_print()</code> to use
<code>librdf_node_write()</code>. If anyone was relying on this
unsupported debug format, this changes the result. Fixes
<a href="http://bugs.librdf.org/mantis/view.php?id=124">Issue#0000124</a>
</p>
<p>Deprecate <code>librdf_node_to_string()</code>,
<code>librdf_node_to_counted_string()</code> for
<code>librdf_node_write()</code> since these were really only meant
for internal use.</p>
<p>Adjusted <code>librdf_node_to_string()</code>,
<code>librdf_node_to_counted_string()</code> to use construct an
iostream to a string and use <code>librdf_node_write()</code> to
create the strings. Thus the format is now an N-Triples term rather
than the older debug format. These functions are still for debugging
and deprecated for <code>librdf_node_write()</code>.
</p>
<h3>Query Class Changes</h3>
<p>Fix rasqal query engine integration to allow querying over
the Redland graph names (context URIs) and binding variables to the names.
Fixes
<a href="http://bugs.librdf.org/mantis/view.php?id=382">Issue #000382</a>.
</p>
<p>Fix query engine to prevent runtime warning for models with no
contexts (graphs) when using GRAPH in a query.
</p>
<p>Added <code>librdf_query_languages_enumerate()</code> function
to list supported query languages.
</p>
<p>Made the Virtuoso storage engine (name 'virtuoso') use the internal
Rasqal query results formatting API rather than an internal copy of
a few query result formatters.
</p>
<h3>Query Results Class Changes</h3>
<p>Added
<code>librdf_new_query_results_formatter2()</code> with
name, mime type and fomrat URI args deprecating
<code>librdf_new_query_results_formatter()</code> and
<code>librdf_new_query_results_formatter_by_mime_type()</code>
with a mixture.
</p>
<p>Altered all query result formatters to all take format name,
mime_type and uri args. Added
<code>librdf_query_results_to_counted_string2()</code>,
<code>librdf_query_results_to_string2()</code>,
<code>librdf_query_results_to_file_handle2()</code>,
<code>librdf_query_results_to_file2()</code> deprecating the
functions without the 2 suffix.
</p>
<h3>Serializer Class Changes</h3>
<p><code>librdf_serializer_serialize_stream_to_iostream()</code> and
<code>librdf_serializer_serialize_model_to_iostream()</code> now
document their ownership transfer of the <code>raptor_iostream</code>
object. Fixes
<a href="http://bugs.librdf.org/mantis/view.php?id=372">Issue #0000372</a>
</p>
<h3>Statement Class Changes</h3>
<p>Added <code>librdf_statement_encode2()</code>,
<code>librdf_statement_encode_parts2()</code>,
<code>librdf_statement_decode2()</code> taking a world arg,
deprecating those without the 2 suffx and no world arg.
</p>
<p>Added <code>librdf_statement_write()</code>
using <code>librdf_node_write()</code> to format the statement as
N-Triples.
</p>
<p>Adjusted <code>librdf_statement_to_string()</code> to
use librdf_statement_write() to write statement in N-Triples format
rather than the previous format.
</p>
<h3>Stream Class Changes</h3>
<p>Added <code>librdf_stream_write()</code> deprecating
<code>librdf_stream_print()</code> debug routine.
</p>
<h3>Storage Class Changes</h3>
<p><code>librdf_storage_context_remove_statement()</code> now checks
that statement is non-NULL and allows NULL context. Now matches
function spec.
</p>
<p>Storage Postgresql (name 'postgresql'). Fix the
contains-statement method as called by
<code>librdf_storage_contains_statement()</code> to work using patch
from Andrew Malton - thanks.
</p>
<p>Storage Trees (name 'trees'). Fix the crash bug when comparing
nodes one of which has a language and the other doesn't.
<a href="http://bugs.librdf.org/mantis/view.php?id=350">Issue #0000350</a>.
</p>
<p>Storage Virtuoso (name 'virtuoso'). Fix to use the internal Rasqal
query formatting API to allow returning any result format. This is
not using a very efficient mechanism since it results in about 3
copies of the result set: in librasqa;, librdf and virtuoso but it
works and does not duplicate code. Update the storage to support
newer Virtuoso versions such as recent ODBC extensions. Added support
for
<code>SQL_DESC_COL_LITERAL_LANG</code>
<code>SQL_DESC_COL_LITERAL_TYPE</code> and
<code>SQL_DESC_COL_BOX_FLAGS</code> from
Virtuoso ODBC Implementation -
<a href="http://docs.openlinksw.com/virtuoso/odbcimplementation.html#virtodbcsparql">Virtuoso ODBC RDF Extensions for SPASQL</a>.
Tested with Virtuoso 5.0.13 open source edition.
</p>
<h3>URI Class Changes</h3>
<p>Added <code>librdf_new_uri2()</code> taking a counted URI string
argument, avoiding <code>strlen()</code>s.
</p>
<h3>World Class Changes</h3>
<p>Export <code>librdf_world_set_raptor()</code> and
<code>librdf_world_get_raptor()</code> to get/set the raptor world.
These are only used when librdf is built with Raptor V2.
</p>
<h3>Internal changes</h3>
<p><code>struct librdf_query_factory_s</code> methods
<code>new_results_formatter</code> and
<code>new_results_formatter_by_mime_type</code> are replaced by one
<code>new_results_formatter</code> method that takes name, mime type
and format URI args. It also gains a
<code>new_results_formatter2</code> factory method for query results
formatting. The only implementor of this factory is the internal
Rasqal query results formatter.
</p>
<h3>Language Bindings (SWIG) changes</h3>
<p>Exposed several functions (some new) that make sense to
higher-level libraries bound to librdf via SWIG:</p>
<ul>
<li><code>librdf_hash_from_string()</code> to build a hash from a string; useful for encoding storage options.</li>
<li><code>librdf_hash_to_string()</code> to turn a hash into a string; useful for decoding storage options.</li>
<li><code>librdf_model_add_typed_literal_statement()</code> to add a typed literal statement direct to a graph.</li>
<li><code>librdf_new_node_from_normalised_uri_string()</code> to create a URI node.</li>
<li><code>librdf_new_node_from_uri_local_name()</code> to create a URI node</li>
<li><code>librdf_node_get_li_ordinal()</code> to get the 1 from a rdf:_1 predicate node.</li>
<li><code>librdf_parser_check_name()</code> for checking parser names.</li>
<li><code>librdf_query_results_is_syntax()</code> to check if query result is a syntax.</li>
<li><code>librdf_query_results_to_file2()</code> supplementing the deprecated <code>librdf_query_results_to_file()</code></li>
<li><code>librdf_query_results_to_string2()</code> supplementing the deprecated <code>librdf_query_results_to_string()</code></li>
<li><code>librdf_serializer_check_name()</code> for checking serializer names.</li>
<li><code>librdf_serializer_serialize_stream_to_file()</code> to go along with it's pair that serializes a model to a file.</li>
<li><code>librdf_serializer_serialize_stream_to_string()</code> to go along with the pair that serializes a model to string.</li>
<li><code>librdf_world_set_logger()</code> to set for logging callbacks.</li>
</ul>
<h3>Other changes</h3>
<p><code>rdfproc(1)</code> utility now send non-result information
messages to stderr, indented to make this more useful for scripting.
It also gains '-q' (--quiet) and '-V' options (--verbose) to control
this output - entirely removing it (quiet) or being more verbose.
That is '-q -v' is equivalent to the default verbosity. Change based
on patch by Norman Gray in issue - thanks! Fixes
<a href="http://bugs.librdf.org/mantis/view.php?id=334">Issue #0000334</a>
</p>
<p><code>rdfproc(1)</code> utility now fails with error when using -n
(make a new storage) to a read only operation such as a query. Fixes
<a href="http://bugs.librdf.org/mantis/view.php?id=383">Issue #0000383</a>.
</p>
<p>Switched to GIT source control.
</p>
<p>Added HACKING.md documenting code style.
</p>
<p>Added <code>examples/example8.c</code> to show how to serializer
query results to strings when queries return either variable bindings
or triples forms.
