The latest Saxon-JS release is 1.1.0, released on 9 May 2018. To be able to use all new features, it is recommended that SEFs are produced with Saxon-EE 22.214.171.124 or later (in general SEFs should be produced with Saxon-EE 126.96.36.199 or later for use with Saxon-JS 1.x).
For earlier releases, see Saxon-JS archive.
Although the source code of Saxon-JS is made available, the product is not open source. The code is the intellectual property of Saxonica, except for the open source components listed at Third-party Components.
For licensing purposes Saxon-JS is considered to be part of Saxon Enterprise Edition, and purchasing a Saxon-EE license entitles you to use and deploy Saxon-JS. The basic model for Saxon-JS is that we charge for development, not for deployment. A Saxon-EE license is required to produce an SEF (stylesheet export file), but no license is needed for run time deployment on a web browser. The Saxon-EE license conditions can be found at Saxon Licensing.
For release notes, documentation, information on installing the software, and details about earlier releases, see the Saxon-JS product page.
