HyperSQL DataBase (HSQLDB) is a modern relational database manager that conforms closely to the SQL:2016 Standard and JDBC 4.2 specifications. It supports all core features and many optional features of SQL:2016.
The first versions of HSQLDB were released in 2001. Version 2, first released in 2010, was a complete rewrite of most parts of the database engine.
This documentation covers HyperSQL version 2.5.1. This documentation is regularly improved and updated. The latest, updated version can be found at http://hsqldb.org/doc/2.0/

You may be reading this document right now at http://hsqldb.org/doc/2.0, or in a distribution somewhere else. I hereby call the document distribution from which you are reading this, your current distro.
http://hsqldb.org/doc/2.0 hosts the latest production versions of all available formats. If you want a different format of the same version of the document you are reading now, then you should try your current distro.

Sometimes, distributions other than http://hsqldb.org/doc/2.0 do not host all available formats. So, if you can't access the format that you want in your current distro, you have no choice but to use the newest production version at http://hsqldb.org/doc/2.0.
