## [Announcing Saxon 13.0](https://www.mbsplugins.de/archive/2026-05-30/Announcing_Saxon_130/monkeybreadsoftware_blog_xojo) We got notice that [Saxonica](https://www.saxonica.com/) released the version 13.0 of their Saxon Library: > The first release of Saxon 13 has just been published. This is a new release for Java, C#, C/C++, PHP, and Python. The highlights in this release are: > > - A redesigned Schema API that allows multiple schemas to coexist. You can now validate an input document with one schema and the result with another, even for the same namespace. > > - More than 175 features from the draft 4.0 specifications are now available in Saxon-PE and Saxon-EE, including: > > - On the topic of 4.0, > > - Support for SaxonC extension functions written in C++, Python, and PHP. > > - SaxonCS-HE, our first release of the free Saxon HE product built for .NET with C#. > > For more details, please consult [the documentation](https://www.saxonica.com/documentation13). > > If you encounter any issues with Saxon 13.0, please [report them](https://saxonica.plan.io/projects/saxon/issues) on our issue tracker. Our MBS Plugins include Saxon 12.9 currently. We will soon review the new version and integrate it into MBS Plugins. If any issues prevent that, we may report them and wait for the 13.1 version. Our Saxon integration for FileMaker is a powerful add-on to use XLST 3.0, XPath 3.1 and XQuery 3.1 in your solutions.
