+Version v0.15.8 of SILE has been released and is [available for download][release]!
+See the included [CHANGELOG.md][changelog] or review the [commit history][commits] for more explicit details.
+
+### Summary of Improvements
+
+This release fixes build issues for macOS (Darwin) we introduced back in v0.15.6 that have been holding back releases on Homebrew and Nix's Darwin support.
+In addition to the build support, the `macfonts` font loader has been tweaked to support fallback to `fontconfig` when a font is not found so it will behave more similarly to Linux builds.
+
+On all platforms, CLI output is a bit cleaner.
+Many runtime errors now output cleaner message formatting instead of a jumble of joined lines.
+Also some error chains where one error would trigger another have been resolved.
+
+The math support continues to be refined by [Didier Willis](http://github.com/Omikhleia), this release bringing a few new commands and features, better behavior parity with MathML, and a couple bug fixes.
+
