[ANN] nokogiri 1.6.0 Released

nokogiri version 1.6.0, "GORUCO 2013 edition," has been released!

= Summary

This version of Nokogiri ships and compiles libxml2 and libxslt with
the gem. This should fix most installation issues.

You can override this behavior and use system libraries. See details
below.

Note that the gem file will be larger, since libxml2 and libxslt are
packaged in the "fat source" gem.

Note that gem installation times will be longer, since libxml2 and
libxslt are built at gem install time.

Note that Windows (mswin32, mingw32) gems for 1.6.0 are not yet
available for this version.

Note also that Ruby 1.8.7 is no longer supported.

Nokogiri (鋸) is an HTML, XML, SAX, and Reader parser. Among Nokogiri's
many features is the ability to search documents via XPath or CSS3
selectors.

XML is like violence - if it doesn’t solve your problems, you are not using
enough of it.

= Changes

* Notes

  * mini_portile is now a runtime dependency
  * Ruby 1.9.2 and higher now required

* Features

  * (MRI) Source code for libxml 2.8.0 and libxslt 1.2.26 is packaged
    with the gem. These libraries are compiled at gem install time
    unless the environment variable NOKOGIRI_USE_SYSTEM_LIBRARIES is
    set. VERSION_INFO (also `nokogiri -v`) exposes whether libxml was
    compiled from packaged source, or the system library was used.

* Deprecations

  * Support for Ruby 1.8.7 and prior has been dropped

= Details

Running `nokogiri -v` will now indicate whether the libxml2 version
used is a system library or the packaged version, and where the
packaged version is installed.

```
