HTSQL 2.0.0b1 is released

Published by xi on 2010-09-21

This is the initial beta release: not all features work as specified and some are not implemented yet.

Two backends are supported: PostgreSQL and SQLite. The PostgreSQL backend is more feature-complete.

The SQL translator needs more work: term compiler, the frame assembler and the SQL serializer are of alpha quality.

Many functions from the standard library are not yet implemented or missing a proper serializer, especially for the SQLite backend.
