+- Update to version 0.4.28:
+  + Core: Infrastructure to opt out of listing ops with unmet
+    runtime dependencies.
+  + Build: Set vapi metadata better under meson. Make graphviz' dot
+    library is a run-time not build time dependency.
+  + Operations:
+    - gegl:convert-space and gegl:cast-space operations fixed, and
+      added to build.
+    - icc:load new operation that treats .icc files as images,
+      permitting loading a space into the graph from file.
+  + Workshop: New operation paint-select for an foreground select
+    tool in development.
+- Add disabled pkgconfig(maxflow) BuildRequires: New dependency.
