Hi,

Ruby 1.9.2 has been released. This is the newest release of Ruby 1.9
series.

== About Ruby 1.9.2
Ruby 1.9.2 is mostly compatible with 1.9.1, except the
following changes:
* Many new methods
* New socket API (IPv6 support)
* New encodings
* Random class that supports various random number generators
* Time is reimplemented. There is no longer the year 2038 problem.
* some regexp enhancements
* $: no longer includes the current directory.
* dl is reimplemented on top of libffi.
* new psych library that wraps libyaml. You can use the library instead
of syck.

See [*1][*2] for more detail.

Ruby 1.9 has four support levels.

:Supported
  We verified that Ruby 1.9.2 works fine on it. And we can keep the
1.9.2 maintained on it.
  * Debian GNU/Linux 5.0 on IA32.

:Best Effort
  We verified that Ruby 1.9.2 works mostly fine on them. And I believe
we can keep the 1.9.2 maintained on it.
  * mswin32, x64-mswin64, mingw32
  * MacOS X 10.5 (Intel) and 10.6
  * FreeBSD 6 and later (amd64, IA32)
  * Solaris 10
  * Symbian OS

:Perhaps
  I think Ruby 1.9.2 works fine on them with small modification,
however, it is not verified. Patch is welcome.
  * Other Linux distributions
  * Other versions of MacOS X.
  * cygwin
  * AIX 5
  * Other POSIX-compatible systems
  * BeOS (Haiku)

:Not supported
  I do not think Ruby 1.9.2 works on them. Porting is welcome.
  * Any other systems


== FAQ
:The standard library is installed in /usr/local/lib/ruby/1.9.1
  This version number is "library compatibility version".  Ruby 1.9.2 is
mostly compatible with the 1.9.2, so its library is installed in the
directory.

:It causes a LoadError
  $: no longer includes the current directory. So some scripts need
modification to work correctly. Anyway, your script should not depend on
the current directory as well as possible.
