Release Notes: Support for MacOS X 10.2 and a Python binding were added. The event system was completely redone, and support for user defined events was added. Support for storage permissions was added. Vertex ID caching was moved into the core so that all language bindings benefit from increased efficiency. The DB driver APIs were formalized. Many bugs were fixed, and the build system on all platforms was improved.
Release Notes: This release includes implementation of Java binding for core APIs, reimplementation of the Tcl binding to use Tcl_Obj throughout, reimplementation of the XML input and output to allow facilities to be subclasses and extended, new APIs to allow sharing of storage objects between interpreters in Tcl binding, reimplementation of event notifications, and some major bugfixes in the garbage collector and management of detached vertices and nodes.
Release Notes: Major feature enhancements and bugfixes.
Release Notes: Markers are no longer supported as a storage entity; instead each storage has a distinguished root node. No more explicit deletion; instead nodes and vertices are detached from their container, and their storage is automatically reclaimed when they are no longer referenced by the user program.
Release Notes: Node and vertex deletion have been reimplemented to be 100 times more efficient. New XML input and output facilities have been implemented. Many bugs and memory leaks have been fixed. The efficiency of the Tcl binding has been improved by a factor of 10 for common operations. A mechanism to detect and upgrade older DB formats to newer formats has been implemented. A detection mechanism has been implemented for when a newer DB is read by an older release.
Release Notes: Improved C++ binding, improved efficiency and reliability, improved TCL binding, elimination of many memory leaks, new Java binding, and support for MacOS X.
