Enhancements

• Add Dataset #set_defaults and #set_overrides, used for scoping the values used in insert/update statements
• Allow Models to use the RETURNING clause when inserting records on PostgreSQL
• Raise Sequel:DatabaseError instead of generic Sequel:Error for database errors, dont swallow tracebacks
• Use INSERT ... RETURNING ... with PostgreSQL 8.2 and higher
• Make insert_sql, delete_sql, and update_sql respect the :sql option
• Default to converting 2 digit years, use Sequel.convert_two_digit_years = false to get back the old behavior
• Make the PostgreSQL adapter with the pg driver use async_exec, so it doesnt block the entire interpreter
• Make the schema generators support composite primary and foreign keys and unique constraints
• Work with the 2008.08.17 version of the pg gem
• Disallow abuse of SQL function syntax for types (use :type=>:varchar, :size=>255 instead of :type=>:varchar[255])
• Quote index names when creating or dropping indexes
• Dont have column accessor methods override plugin instance methods
• Allow validation of multiple attributes at once, with built in support for uniqueness checking of multiple columns
• In PostgreSQL adapter, fix inserting a row with a primary key value inside a transaction
• Allow before_save and before_update to affect the columns saved by save_changes
• Make Dataset#single_value work when graphing, which fixes count and paginate on graphed datasets

The binding to server process attempts to use the server network card MAC address. This feature was tested on servers are Mac OS X (Darwin), Linux, Windows XP, although it may also work for FreeBSD, NetBSD, Solaris.

PADL also attempts to use information from $_SERVER variable to encode that server name, server IP, server application path and server application url to the license key. Part of the process also binds the IP Address from the $_SERVER variable if found, but it also attempts to parse the server config file (the same used to get the MAC address) for any more IPs.

The server binding can be disabled if required, and it also possible to block the key being generated for the localhost address (127.0.0.1). The time limiting of the license uses a start period (and a given start offset to allow for time discrepancies) and an expiry date if required. If required when validating a key it is also possible to dial home to check the license key on your own PADL License Server, examples are given.

The PHP_OS and PHP_VERSION of the php that the key was generated for is also encrypted into the key. It is also possible to encrypt additional information into the license key to enable you to place restrictive features in your application to allow the creation of trialware or demoware.
