amalgalite version 0.4.0 has been released.

http://www.copiousfreetime.org/projects/amalgalite/

* Major Enhancements
* update to SQLite3 version 3.6.2 and enable the RTree option by default
* Amalgalite::Requires module allowing ruby code to be 'required' from columns
in an SQLite database
* Amagalite::Requires::Bootstrap extension module enabling low level boot
strapping of the pure ruby Amalgalite code from an sqlite database

* Minor Enhancements
* more indepth information about indexes is available via the Index class
* add support for sqlite3_status and sqlite3_db_status information

* Bugfixes
* fix nil exception when using a declared_data_type on primary key column that
has no declared_data_type
* when Database#transaction is passed a block, the return value is the return
value of the block
* nested transactions are 'faked'. Calling Database#transaction while
Databased#in_transaction? is true does not result in an exception, but
continues on in the current transaction.
* raise LoadError if required in the same program as sqlite3-ruby. These
libraries conflict with each other.
