See the readme for details.

New version supports ActiveModel validations, so has multi-ORM support. It is the only complete date/time validation plugin for Rails.

The grouped_validations plugin allows you to define validation groups which you can check for validity in isolation from the rest of the validations on a model. Handy for multi-page forms or wizard style data entry.

validates_timeliness version 2.2 released with Ruby 1.9 support and a fix for conflict with Shoulda.

validates_timeliness version 2.0.0 is out. I call this the 'Gently, gently' release as it makes fewer assumptions and has a minimal ActiveRecord footprint. Also a couple of more options and extended I18n support.

validates_timeliness date and time validation plugin updated with Rails 2.3 support and some new options added.

For those who need flexible date and time validation in Rails 2.x with I18n support you now have validates_timeliness. Its been around for a while but I thought I better pimp it.
