Examples:

  User.all :joins => :items, :conditions => { :age => 10, :items => { :color => 'black' } }
  Item.first :conditions => { :items => { :color => 'red' } }

Note : Hash key in :conditions is referring to the actual table name or the alias defined in query.

MySQL: treat integer with :limit => 11 as a display width, not byte size, for backward-compatibility.

Make sure associated has_many/habtm objects get saved even when :validate => false is used. [#486 state:resolved]

For example :conditions => ['stringcol::integer = :var', { :var => 10 }]
will no longer raise an exception about ':integer' having a missing value.

Give a more informative error message instead of just raising a load error when mysql gem isn't installed
