# Redland RDF Application Framework - News

## 2003-09-08 Redland 0.9.14 Released

Other minor API changes

See the Detailed 0.9.14 Release Notes for the full list of the changes.

## 2003-08-28 Redland 0.9.13 Released

API CHANGE Node The class was modifed to make objects immutable, removing the set methods and to add new node type convienence methods.
API addition Model Added a method to sync the model to the backing store.
API addition Parser Added methods to allow parsing from strings.
API addition Statement Added method to check for partial statements.
API addition Storage Added a method to sync the backing store.
Better error recovery - most errors return if possible.
Added initial simple threading support (patches by Seth Ladd)
Greatly improved Python API using 2.2 features (Edd Dumbill and Matt Biddulph)
Updated Perl, Python and Java APIs to always return new nodes and statements, removing the need to consider shared object issues.
Updated serializing to RDF/XML to handle datatype literals
Update to Raptor version 0.9.12 (RDF/XML and N-Triples parser) - see Raptor NEWS for changes since 0.9.8.
Extensive portability and other bug fixes.

See the Detailed 0.9.13 Release Notes for the full list of the changes.

## 2003-02-13 Redland 0.9.12 Released

FORMAT CHANGE The persistent storage format was changed to support RDF typed literals and this will require an upgrade of any existing Berkeley/Sleepycat DB stores created by Redland 0.9.11 or earlier. A utility redland-db-upgrade is provided that creates an updated store from an existing one.
API CHANGE Iterator and Stream classes. The next/get_next method is split into get_object always returning a shared object and next methods. get_context method added. (get_object is called current in higher level language APIs)
API CHANGE Model class. Method add_statement no longer takes ownership of the passed in statement. The caller now retains ownership.
API CHANGE Model class. Method add_statements no longer frees the passed in librdf_stream; the caller must free it now.
API CHANGE Node and Model classes. Added RDF Datatyped Literals. Other literal is_wf_xml constructors and methods deprecated.
API CHANGE All literals methods and constructors have no mention of the never-used or supported XML Space argument which is not part of an RDF literal.
Added a script utils/update-api-0912.pl to help automate the API changes as far as possible or warn about those that cannot be automatically updated.
Added contexts - Statements added to Model (when using a Storage that supports contexts) can take an optional Node, returned by the new get_context method on Iterator and Stream classes.
Many portability and compiling fixes (OSX, gcc 3.x, FreeBSD, non-gcc compiler)
Java API classes. Add finished() method replacing useless finalize().
Use Raptor message callbacks to get parser warnings and errors
Build Java API working around the stupid things recent SWIG versions do.
Make Redland work with BDB/Sleepycat DB v4 (as well as v2 and v3)
Python API gains pydoc comments and HTML derived version
Perl and Python APIs now receive Redland message callbacks
Redland URI class now registers with Raptor rather than specially compile Raptor
Added RDF/XML Serializer class and made higher level language APIs to it
Update to Raptor version 0.9.8 (RDF/XML and N-Triples parser) - see Raptor NEWS for detailed changes since 0.9.5
Added skeleton Ruby and PHP APIs
Major source reorganisation.
