"drush fra" produces error "The drush command 'Array features-revert' could not be found."

ATTENTION for Drush support

Version 6.x-1.2 and 7.x-1.x-beta5 (or later) will no longer work with Drush 4.4 or lower. In order to support the upcoming Drush 5 (and continue to support Drush 4.5) we needed to break back support for older versions of Drush.

I didn't see this in the notes for the features release of 6.x-1.2. Would be good to have that in the README. But here's the workaround R.Hendel. I hope that helps.

We can maybe change this ticket to be a bug in documentation only, and then close it out.

The ReadMe has this:

Drush usage
-----------
Features provides several useful drush commands:

- `drush features`

List all the available features on your site and their status.

- `drush features-export [feature name] [component list]`

Write a new feature in code containing the components listed.

- `drush features-update [feature name]`

Update the code of an existing feature to include any overrides/changes in
your database (e.g. a new view).

- `drush features-revert [feature name]`

Revert the components of a feature in your site's database to the state
described in your feature module's defaults.

- `drush features-diff [feature name]`

Show a diff between a feature's database components and those in code.
Requires the Diff module.

Additional commands and options can be found using `drush help`.

Compatibility
-------------
Features provides integration for the following exportables:

- CTools export API implementers (Context, Spaces, Boxes, Strongarm, Page
Manager)
- ImageCache
- Views
- [Other contributed modules][2]

It would be helpful to mention that drush needs to be version 4.5 or higher.

upgraded to drush make 4.5 fixed it for me.
