+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.
+        - new CBOR::XS::safe_filter functionality.
+        - fix a crash when decoding a cyclic data structure using
+          stringref/pack_strings when allow_cycles is disabled.
+        - fix a crash when decoding hash keys with length >= 2**31.
+        - avoid unreasonably long decoding times for certain
+          types of (corrupt) cbor texts.
+        - support arrays and hashes with >= 2**31 members.
+        - avoid overflow on pointer arithmetic when checking whether enough
+          data is available.
+        - fix a memory leak that occured when decoding failed while decoding
+          a tagged value.
+        - do not leak the partially constructed result when stringifying
+          a hash key throws an exception.
+        - various code size and efficiency optimizations (reduced code
+          from 42 to 40kB on my system, despite the new features).
+
+1.5  Wed Apr 27 11:38:39 CEST 2016
         - Math::BigFloat madness workaround, see
           http://blog.schmorp.de/2016-04-23-mathbigfloat-maintainer-fail.html
           (bugreport by zdm@softvisio.net).
         - add text_keys and text_strings options to force CBOR text encoding
           for perl hash keys or all strings, as a result of discussions
           with Fredrik Ljunggren.
-        - remove some weird dead code that was duplication (%FILTER).
+        - implement support for arbitrary-exponent numbers (see
+          http://peteroupc.github.io/CBOR/bigfrac.html, tags 264 and 265)
+          for both en- and decoding.
+        - implement support for rational numbers (see
+          http://peteroupc.github.io/CBOR/rational.html, tag 30) for both
+          en- and decoding.
+        - the above effectively implements all registered CBOR extensions
+          in a sensible manner.
+        - remove some weird dead code that was duplicated (%FILTER).
         - add t/58_hv.t, which tests hashes and the new text_* flags.
-          hashes apparently were not encoded at all in any of the previous
+          hashes apparently were not encoded at all in any of the existing
           tests.
+        - document Math::BigFloat base-2 performance/crash issues.
+        - use stability canary.
