 XSpec consists of a syntax for describing the behaviour of XSLT, XQuery, or Schematron code, and some code that enables you to test the code against those descriptions.

+## Release XSpec v3.0.3
+Release v3.0.3 upgrades its connections with related software. Support for testing Schematron schemas now uses SchXslt as the built-in Schematron implementation. XSLT code coverage is compatible with Saxon 12.4 or later. These are the highlights of XSpec v3.0:
+
+#### Common to Languages Under Test
+
+- XSpec is tested with Saxon 12, 11, and 10, while use of Saxon versions earlier than 12.4 is not recommended.
+- XSpec no longer supports Saxon 9.
+- When comparing XML, you can ignore some or all attributes using three-dot syntax `x:attrs="..."`.
+- XPath function items stored in global variables are testable using syntax `<x:call function="my-function" call-as="variable">`.
+
+#### XSLT
+
+- XSLT code coverage feature is compatible with Saxon 12.4. **Compatibility note:** This upgrade is not backward compatible with earlier Saxon versions. Also, Saxon 12.4 does not report some `xsl:sequence` instructions that are actually hit.
+- XSpec experimentally supports testing with XSLT 4.0 and XPath 4.0. Set `xslt-version="4.0"` on `x:description`, and use an XSLT processor that has support for 4.0 enabled.
+
+#### XQuery
+
+- XSpec experimentally supports testing with XQuery 4.0 and XPath 4.0. Set `xquery-version="4.0"` on `x:description`, and use an XQuery processor that has support for 4.0.
+
+#### Schematron
+
+- SchXslt 1.9.5 replaces the skeleton implementation because the latter is no longer maintained. **Compatibility note:** Some XSpec tests might produce different results with SchXslt.
+- XSpec scenarios can verify the text of messages or diagnostics. Add expected text inside `x:expect-assert` or `x:expect-report`.
+
+Many thanks to all the XSpec contributors who made this release possible!  They are listed in the [release notes](https://github.com/xspec/xspec/releases/tag/v3.0.3).
