## Notes

### Incompatibility

There are three notable incompatibilities we know of:

  - The default encoding for ruby scripts is now UTF-8 [#6679].  Some 
people
    report that it affects existing programs, such as a some benchmark 
programs
    that have become very slow [ruby-dev:46547].
    The spec may change for the official release.

  - iconv was removed, which had already been deprecated when M17N was
introduced
    in ruby 1.9.  Use String#encode, etc. instead.

  - There is ABI breakage [ruby-core:48984].  We think that normal users
    can/should just reinstall extension libraries.
    You should be aware: "DO NOT COPY .so OR .bundle FILES FROM 1.9".

There are some comparatively small incompatibilities.  [ruby-core:49119]
Please report any other incompatibility you notice.

FYI: We are creating upgrade notes, but some parts are already outdated.

  - http://bugs.ruby-lang.org/projects/ruby/wiki/200Up...

### Status of Refinements

2.0.0 will include refinements as an "experimental feature" because we 
could
not agree on its detailed spec.
Note that the behavior may change in future versions of Ruby.

### Support level of Each Platform

We plan to decide "supported level list" depending upon whether 
2.0.0-rc1
builds/works or not on each platform.
Please try it on your favorite platform(s), and report if it works all 
right
or not!

### Schedule

There are still minor known issues.  We are now engaged in fixing them.
We will release 2.0.0-rc2 in early February, and 2.0.0-p0 at 24th Feb.
(the 20th anniversary of Ruby).

Thanks!

Very sorry, I forgot one of the most important section!


## Special thanks

We appreciate all users who gave feedback to the preview releases of 
2.0.0.
I'm grateful for all the committers' hard work to implement the new
