-QCBOR_DISABLE_UNCOMMON_TAGS disables the decoding of explicit tags for
-base 64, regex, UUID and MIME data. This just disables the automatic
-recognition of these from a major type 6 tag.
+QCBOR_DISABLE_UNCOMMON_TAGS is removed from QCBOR v2. It didn't save
+very much and you can get the same effect by not install
+the tag content handlers.
 
 QCBOR_DISABLE_EXP_AND_MANTISSA disables the decoding of decimal
 fractions and big floats.
