+## Release XSpec v3.1.2
+
+XSpec 3.1.2 fixes bugs in the coverage status shown in XSLT code coverage reports. This release also updates dependencies. These are the highlights of XSpec v3.1:
+
+#### Common to Languages Under Test
+
+- XSpec is tested with Saxon 12.5, except that the detailed contents of XSLT code coverage reports are tested with Saxon 12.4.
+- The XSpec schemas enforce the boolean values for the `x:expand-text` attribute and provide a Schematron Quick Fix for `expand-text` attributes on non-XSpec elements.
+
+#### XSLT
+
+- XSLT code coverage reports include a new coverage status of "unknown" for situations where XSpec has insufficient data to judge whether a node was hit or missed. Some instances of hit/miss/unknown determinations differ based on the Saxon version used for generating the report. While both Saxon 12.4 and 12.5 are supported, 12.4 is currently preferred for coverage reporting.
+
+#### XQuery
+
+- XSpec is tested with BaseX 11.3.
+
+#### Schematron
+
+- SchXslt 1.10 replaces SchXslt 1.9.5 as the built-in Schematron implementation.
+
+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/v3.1.2).
