From: Luis Lavena on
I'm pleased to announce the release of final RubyInstaller packages.

For those not already familiar with RubyInstaller, these versions
continue the great work started with the original One-Click Installer
by providing both 1.8 and 1.9 versions of MRI Ruby for Windows.

RubyInstaller is powered by GCC compiler, we provide as
convenience an optional Development Kit, which now makes possible
to install RubyGems that, until today, were not readily or easily
available to Windows users.

This release also focuses on improving the installation process and
ensuring a much more pleasant experience for existing and new users of
Ruby on Windows.

= Before installing

If you're upgrading from previous RubyInstaller packages, please
uninstall these versions before proceeding. Don't worry, any gems
that you installed or compiled since installed will not be removed.

Since the new RubyInstaller uses a different compiler, we highly advise
that you avoid attempting to install over any previous One-Click Installer
installation, or any other variant versions (InstantRails, BitNami, etc.)

We recommend that you backup your previous installation, take note of the
details, your installed gem list, etc and proceed to completely uninstall
any legacy installations.
