= New Features
* The add_* association methods now accept a primary key, and
associates the receiver to the associated model object with that
primary key:
artist.add_album(42)
# equivalent to: artist.add_album(Album[42])
* The validation_class_methods plugin now has the ability to
reflect on validations:
Album.plugin :validation_class_methods
Album.validates_acceptance_of(:a)
Album.validation_reflections
# => {:a=>[[:acceptance, {:tag=>:acceptance, :allow_nil=>true,
:message=>"is not accepted", :accept=>"1"}]]}
= Other Improvements
* In the postgres, mysql, and sqlite adapters, typecasting now uses
methods instead of procs. Since methods aren't closures (while
procs are), this makes typecasting faster (up to 15%).
* When typecasting model column values, the classes of the new and
existing values are checked in addition to the values themselves.
Previously, if the new and existing values were equal (i.e. 1.0
and 1), it wouldn't update the value. Now, if the classes are
different, it always updates the value.
* Date and DateTime objects are now handled correctly when using
prepared statements/bound variables in the jdbc adapter.
* Date, DateTime, Time, true, false, and SQL::Blob objects are now
handled correctly when using prepared statements/bound variables
in the sqlite adapter.
* Sequel now uses varbinary(max) instead of image for the generic
File (blob) type on Microsoft SQL Server. This makes it possible
to use an SQL::Blob object as a prepared statement argument.
* Sequel now handles blobs better in the Amalgalite adapter.
* When disconnecting a connection using the sqlite adapter, all
open prepared statements are now closed first. Previously,
attempting to disconnect a connection with open prepared statements
resulted in an error.
* The license file has been renamed from COPYING to MIT-LICENSE, to
make it easier to determine at a glance which license is used.
= Backwards Compatibility
* Because Sequel switched the generic File type from image to
varbinary(max) on Microsoft SQL Server, any migrations/schema
modification methods that used the File type will now result in a
different column type than before.
* The MYSQL_TYPE_PROCS, PG_TYPE_PROCS, and SQLITE_TYPE_PROCS
constants have been removed from the mysql, postgres, and sqlite
adapters, respectively. The UNIX_EPOCH_TIME_FORMAT and
FALSE_VALUES constants have also been removed from the sqlite
adapter.
* Typecasting in the sqlite adapters now uses to_i and to_f instead
of Integer() and Float() with rescues. If you put non-numeric
data in numeric columns on SQLite, this could cause problems.
