DataMapper 0.2.5 Release

Notes:
Bug-fix release.

Some minor API changes and enhancements (MyModel#[] only accepts a
primary key now, not an options hash).

database.get (equiv to AR’s find_by_id) is approximately 25% faster
than previous.

No longer must you inherit from DataMapper::Base. Instead now you can
include the DataMapper::Persistence module in your models (::Base is
preserved for backwards compatibility).

Changes:
– 0.2.5
