== Improvements

- supports 21 new character encodings.
- works better with RubyGems.
- handles SEGV better when system stack overflows.
- fixed a bit of regexp imcompatiblity to Perl5 and old Ruby.
- many bugs in Time#strftime and Date#strftime fixed.
- process termination got faster.
- allows long style options in RUBYOPT.
- You can “make test” without installing ruby.
- You can derive a class from Fiber correctly.
- many bugs fixed.

== Release schedule  
Current Status:

- Language features are effectively “frozen”.
- But we could not finish multilingualization tasks for standard  
libraries. For example, irb does not recognize magic comments.
- So changes to some of standard libraries continue.
  - irb
  - erb
  - cgi
  - …

Schedule:

- 25 Dec, 2008: Ruby 1.9.1 release candidate
- 25 Jan, 2009: Ruby 1.9.1

Thanks

Many thanks for mentioning this. However, processing of these  
encodings was already supported. What is new is that these  
encodings can now also be converted (from/to UTF-8 and from  
there to others).

We are working on conversions for some more encodings. If anybody  
has a conversion that they want to see supported soon, please  
tell me.

Regards, Martin.
