+TODO: type cast tests.
+TODO: possibly implement https://peteroupc.github.io/CBOR/extended.html, but NaNs are nonportable. rely on libecb?
+TODO: https://github.com/svaarala/cbor-specs/blob/master/cbor-nonutf8-string-tags.rst, but maybe that is overkill?
+
+	- 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.
+        - 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).

         - Math::BigFloat madness workaround, see
