Serialize JSON attribute value
NULL, not JSON

update_attributewhen the value of the attribute to be updated is unchanged.
Always store errors details information with symbols.
When the association is autosaved we were storing the details with string keys. This was creating inconsistency with other details that are added using the
Errors#addmethod. It was also inconsistent with the
To fix this inconsistency we are always storing with symbols. This will cause a small breaking change because in those cases the details could be accessed as strings keys but now it can not.

touchon a model using optimistic locking will now leave the model in a non-dirty state with no attribute changes.
Using a mysql2 connection after it fails to reconnect will now have an error message saying the connection is closed rather than an undefined method error message.
PostgreSQL array columns will now respect the encoding of strings contained in the array.
Inverse association instances will now be set before
after_initializecallbacks are run.
Remove unnecessarily association load when a
belongs_toassociation has already been loaded then the foreign key is changed directly and the record saved.
Remove standardized column types/arguments spaces in schema dump.
Avoid loading records from database when they are already loaded using the
pluckmethod on a collection.
Remove text default treated as an empty string in non-strict mode for consistency with other types.
Strict mode controls how MySQL handles invalid or missing values in data-change statements such as INSERT or UPDATE. If strict mode is not in effect, MySQL inserts adjusted values for invalid or missing values and produces warnings.

Sqlite3 migrations to add a column to an existing table can now be successfully rolled back when the column was given and invalid column type.
Doing count on relations that contain LEFT OUTER JOIN Arel node no longer force a DISTINCT. This solves issues when using count after a left_joins.
