+- Update to version 6.0.0:
+  + Add API to pre-process the face and speed up future subsetting
+    operations on that face. Provides up to a 95% reduction in
+    subsetting times when the same face is subset more than once.
+  + Shaping have been speedup by skipping entire lookups when the
+    buffer contents don't intersect with the lookup. Shows up to a
+    10% speedup in shaping some fonts
+  + The HarfBuzz subsetter can now drop axes by pinning them to
+    specific values (also referred to as instancing)
+- Drop harfbuzz-5.3.1-Fix_check-symbols_failure.patch: Fixed
+  upstream.
