# 1.8.0 / 2017-06-04
## Backwards incompatibilities
This release ends support for Ruby 2.1 on Windows in the `x86-mingw32` and `x64-mingw32` platform gems (containing pre-compiled DLLs). Official support ended for Ruby 2.1 on 2017-04-01.
Please note that this deprecation note only applies to the precompiled Windows gems. Ruby 2.1 continues to be supported (for now) in the default gem when compiled on installation.
## Dependencies

=== 1.6.8.1 / 2016-10-03
==== Dependency License Notes
Removes required dependency on the `pkg-config` gem. This dependency
was introduced in v1.6.8 and, because it's distributed under LGPL, was
objectionable to many Nokogiri users (#1488, #1496).
This version makes `pkg-config` an optional dependency. If it's
installed, it's used; but otherwise Nokogiri will attempt to work
around its absence.
=== 1.6.8 / unreleased
==== Security Notes
[MRI] Bundled libxml2 is upgraded to 2.9.4, which fixes many security issues. Many of these had previously been patched in the vendored libxml 2.9.2 in the 1.6.7.x branch, but some are newer.
See these libxml2 email posts for more:
* https://mail.gnome.org/archives/xml/2015-November/msg00012.html
* https://mail.gnome.org/archives/xml/2016-May/msg00023.html
For a more detailed analysis, you may care to read Canonical's take on these security issues:
* http://www.ubuntu.com/usn/usn-2994-1
[MRI] Bundled libxslt is upgraded to 1.1.29, which fixes a security issue as well as many long-known outstanding bugs, some features, some portability improvements, and general cleanup.
See this libxslt email post for more:
* https://mail.gnome.org/archives/xslt/2016-May/msg00004.html

* Use Symbol#to_proc where we weren't previously. (#1296) (Thanks, Bruno Sutic!)
* XML::DTD#each uses implicit block calls. (Thanks, @glaucocustodio!)
* Fall back to the `pkg-config` gem if we're having trouble finding the system libxml2. This should help many FreeBSD users. (#1417)
* Set document encoding appropriately even on blank document. (#1043) (Thanks, @batter!)
==== Bug Fixes

1.6.0 / 2013-06-08

mentioned in both.
Deprecations
Remove pre 1.9 monitoring from Travis.

-v`) exposes whether libxml was compiled from packaged source, or the system
library was used.
