+TODO: as_object -> key value pair list to allow non-string hash keys
+        - shared references were not decoded correctly: instead of getting
+          multiple references to the same object, you got the same
+          reference to the same object, causing a number of issues. For
+          example, modifying the reference would modify all places the
+          reference was used, and encoding the decoded structure would
+          unshare the previously shared hashes, as trheir reference count
+          would be 1. Fixcing this was rather involved, as perl lacks the ability
+          to easily swap or copy arrays and hashes.
+	- \0, \1, \undef do not work, and were not intended to ever work, as
+          special values, despite being mentioned in the documentation (reported
+          by nuclightq).
+
+1.86 Thu 04 Nov 2021 17:48:16 CET
+	- fixed a wrong printf format specifier (reported by Petr Písař).
+
+1.85 Sat 23 Oct 2021 04:59:56 CEST
+	- left debugging printf in code, need a test for that :(
+
+1.84 Thu 21 Oct 2021 03:11:52 CEST
+	- fix a bug in validate_utf8 where we call perl's is_utf8_string with
+          a lenght of zero for empty strings, but perl interprets that as
+          "calculate length", causing spurious validation errors for
+          empty strings.
+	- include validate_utf8 in new_safe.
+	- avoid some warnings.
+
+1.83 Tue Dec  8 09:27:06 CET 2020
+	- add CBOR::XS::as_map cast function.
+
+1.82 Tue Dec  1 02:47:40 CET 2020
+	- add CBOR::XS::as_bool cast function.
+
+1.81 Mon Nov 30 19:29:33 CET 2020
+	- cast functions were broken due to last-minute renaming. thats
+          what you get for not having a tessuite.
+	- Math::BigInt and Math::BigFloat are pretty broken (again),
+          so disable some tests. (try printing the bigfloat
+          799999999999999999998E99999999999999999998).
+
+1.8  Sun Nov 29 22:35:13 CET 2020
+	- experimental support for some type casts, as well as embedding
+          raw cbor data.
+
+1.71 Thu Nov 15 20:52:13 CET 2018
+	- work around what smells like a perl bug w.r.t. exceptions
+          thrown in callbacks.
+	- update libecb.
+
+1.7  Tue Jun 27 04:02:23 CEST 2017
+	- SECURITY FIX: fix two bugs found by american fuzzy lop,
+          upgrade is advised if you accept data from untrusted
+          sources.
+        - an out-of bound sharedref or stringref index could cause an
+          out of bounds access - might be exploitable.
+        - a decoding error during indefinite array or hash decoding
+          could cause an endless loop.
+
+1.6  Wed Dec  7 15:13:23 CET 2016
         - greatly expand the SECURITY IMPLICATIONS and similar sections.
         - new constructor new_safe, to create a secure CBOR::XS object.
         - new option forbid_objects, to disallow serialisation.
