+macaulay2 (1.19.1+ds-2+rpi1) bookworm-staging; urgency=medium
+
+  [Changes introduced in 1.18+ds-1+rpi1 by Peter Michael Green]
+  * Disable testsuite.
+  * Link individual font files rather than whole directory to avoid errors
+    on ".uuid" file.
+  * Disable upstream clean target, it's worse than useless
+  * Start writing manual cleanup (far from complete at this point)
