Hi,

How about reconsidering the feature freeze plan.

When this plan is decided in July, it was based on the assumption that
most feature of Ruby 1.9 was already fixed and we could spend time to
make ruby stable.

However, Ruby is still changing now and near future.
This is because
* Ruby 1.9 haven't used in large applications yet.
* too radical changes of some libraries
We need more review to Ruby core and libraries.
This gap is enough to break the assumption.

So how about reconsidering the feature freeze plan.
But continual release is important for feedbacks.

My new plan is,
* Ruby 1.9.1 will be released in 2008-12-25.
* Ruby 1.9.1 doesn't assure ABI Compatibility to future Ruby 1.9 series.
* Ruby 1.9.2 may break compatibility to 1.9.1
  if the change is allowed by people and matz and yugui.
