0.9.0 stable release

0.8.0 stable release

This release focused on three different areas:

1. Performance improvements: Teaks to the table implementation to reduce memory pressure when manipulation large corpora of results.
2. New server option on the command line tool: The server command starts a simple HTTP endpoint for BQL commands. The endpoint returns the query results in JSON format.
3. New CONSTRUCT BQL statements: Implements the CONSTRUCT statement target to create new facts by querying existing facts in graphs.

0.7.0 stable release

This release highlights include a new desc command on the bw REPL console. It also introduces a simple tracer during query execution. This tracer is accessible from bw REPL via the start tracing and stop tracing commands. There is also an incompatible API change to the driver definition affecting thing the Triples graph function. Finally, the release also include major bug fixes, query performance improvements.

Changelog

0.6.0 emergency release

This release emergency release patches two important issues: (1) stale reification blank node generation, and (2) sticky broken semantic state after parsing invalid statements. You should upgrade as soon as possible and stop using any version prior version due to the risk of reification corruption and semantic query staleness.
