Hi,

Oracle enhanced adapter 1.5.5 has been released.

## 1.5.5 / 2014-05-23

* Enhancements
* Oracle NUMBER datatype can be handled as Rails :float datatype [#418]
- Default NUMBER datatype handled as :decimal to keep compatibility
- Configured by setting `self.number_datatype_coercion = :float`
* Add link to supported Oracle database version, JDK and Oracle JDBC
Driver version [#438]
* Support `without_prepared_statements?` to handle
`unprepared_statement` [#447]

* Bug Fix
* Associations with name `record` do not work correctly since Rails 4 [#435]
* Skip another Oracle Text test when Oracle 12c used [#437]
* Tag bind params with a bind param object [#444]

Thanks for the great contribution #418 from @aledovsky and @substars
who originally opened #258.

This version supports both Rails 4.1.x and Rails 4.0.x.

Thanks,
