ActiveRecord Extensions 0.0.4 Is Released

## What is ActiveRecord Extensions?

ActiveRecord Extensions is a library which extends the power of  
ActiveRecord providing lower level support for more database  
specific features and optimizations.

## What features are currently supported?

- MySQL users will enjoy multi value insert statement support using the  
‘import’ method. This supports mass importing of data  
using ActiveRecord with or without validations. It also provides support  
for ON DUPLICATE KEY UPDATE feature that MySQL offers
- MySQL users will also benefit from extended ‘find’ method  
functionality. You can now search with arrays, ranges, regular  
expressions.

## Is This MySQL specific?

Currently yes, but in the future no. PostgreSQL is the next db adapter  
to extend the functionality to, but currently I haven’t  
heard much word from the ActiveRecord / PostgreSQL community on this  
type of functionality, so I haven’t made it a priority.
