NextReleaseNotes

• Fixed a bug in compiled queries around not-yet-existing types.
• Fixed a bug when using HyperGraph.define on HGValueLink.
• Fixed issue #91 (on Google Code), orderedLinkCondition throws NPE in hashCode
• Fixed concurrency issue in checkpoint thread
• Fixed bug in indexing derived types
• Fixed some bugs in Java type inference, including missing hashCode implementations
• Bug fix in PositionedIncidentLink (thanks Yuqing Tang) and added non-Ref constructors to that class.
• Fixed bug in HGEnvironment lookup by DB location
• Added ability to analyze a query to detect time consuming scans and joins.
• Added version information to each database instance, through HGDatabaseVersionFile (see HGEnvironment.getVersions(location)).
• Fixed a bug when creating a new type for a HGLink that is also a serializable: a link with an empty value is created in that case because the intention of serializable support is for classes not written for HGDB. Classes written for HGDB should expose their state through standard bean properties.
• Improved serialization framework of P2P using mjson (https://github.com/bolerio/mjson)
• Comprehensive test suite for storage layer (thanks to Yuriy Sechko)
• Support of OSGi: all modules are now separate OSGi bundles
• Improvemed query performance through parellelization
• Added query analysis mechanism to keep track of decision made during compilation process (see AnalyzedQuery class)
• Added some limited ability to customize the query compilation process with custom query expression transformations
