Hi all,

As announced before, Ruby 1.9.1 features will be frozen on 25 September.

After the time,
 * Ruby level APIs must not changed.
 * C level APIs will must not changed without discussion on
ruby-core/ruby-dev.
   * All structures, data types, variables, functions and macros in
include/ruby/*.h are regarded as public C level APIs.
   * Move it from include/ruby/*.h anything you want not to publish.

And I will create the ruby_1_9_1 branch and release 1.9.1 RC1 on 25
October. After the time,
 * C level APIs will must not changed.

Also the C level APIs of 1.9.x must have backward binary-compatibility
to 1.9.1.


Regards,
