* A swift adapter was added to Sequel. Swift is a relatively new
ruby database library, built on top of a relatively new backend
called dbic++. While not yet considered production ready, it is
very fast. The swift adapter is about 33% faster and 40% more
memory efficient for selects than the postgres adapter using pg
with sequel_pg, though it is slower and less memory efficient
for inserts and updates.
Sequel's swift adapter currently supports only PostgreSQL and
MySQL, but support for other databases will probably be added in
the future.
= Other Improvements
* Sequel now correctly literalizes DateTime objects on ruby 1.9 for
databases that support fractional seconds.
* The identity_map plugin now handles composite keys in many_to_one
associations.
* The rcte_tree plugin now works when the model's dataset does not
select all columns. This can happen when using the lazy_attributes
plugin on the same model.
* Sequel now supports INTERSECT and EXCEPT on Microsoft SQL Server
2005+.
* The Database#create_language method in the shared PostgreSQL
adapter now accepts a :replace option to replace the currently
loaded procedural language if it already exists. This option
is ignored for PostgreSQL versions before 9.0.
* The identity_map plugin now handles cases where the plugin is
loaded separately by two different models.
= Backwards Compatibility
* While not technically backwards compatibility related, it was
discovered that the identity_map plugin is incompatible with
the standard eager loading of many_to_many and many_through_many
associations. If you want to eagerly load those associations and
use the identity_map plugin, you should use eager_graph instead
of eager.
