 MaintainerNotes: |-
-    Requires Android Build Tools <= 30.0.3. The build script uses 'dx' that
-    seems to be gone in 31.0.0.
+    Until version 1.13.1,
+    required the 'dx' tool from Android Build Tools <= 30.0.3.
+    Starting from version 1.14.0,
+    requires FontForge >= 20201107 which is too recent for some distros.
