Roadmap of field validation

1,After there are 500 sites install 7.x-2.x, we release 7.x-2.0-RC1,
2,After there are 1000 sites install 7.x-2.x, we release 7.x-2.0,

From my point, 7.x-2.x is more stable and flexble than 7.x-1.x.

Before release the stable version of 7.x-2.0, there are still some tasks to do,
1,Polish the User interface text. I am chinese, I try my best to make them understandable,
but some guys still does not understand my meanings.
2,Write more document, write document for each validator.
3,Improve the UI provide by Ctools Export

Some tasks will not be done:
We do not add more new validators
Do not integrate token module
That means we will not add new features to 7.x-2.x.

A long task need to be done:
Since 7.x-2.0-beta2, we support two methods to set error message, Why?
Using form_set_error provided by form api, using errors provided by field api.
We need write document why we support two methods, help other module implement hook_field_widget_error to integrate field validation
