Release Notes: This release fixes an assortment of small issues. Most importantly, it cleans up the license, which was a little contradictory and confused. (Not all files had the same license.) The entire package is now released under the modified BSD license (no advertising clause). Despite the "beta" designation, this release has far fewer bugs and is much more compliant with the XPath specification than the official 1.0 release. If you're using 1.0, you should upgrade.
Release Notes: The JavaDoc was expanded. Various parts of the code base were cleaned up and optimized. A couple of areas where Jaxen wasn't correctly implementing the XPath specification were addressed. It is now a little easier not to include the Jaxen extension functions if you don't want to.
Release Notes: This final 1.0 non-beta release includes many bugfixes and a slightly redesigned public API for ease of use and clarity.
