 ### 1.0.0 (unreleased)
 
-**Fixes**:
+**BREAKING CHANGES**:
 
-* Catch a buffer overflow when formatting the error message
-* Import latest upstream sds. This breaks applications that are linked against the old hiredis v0.13
-* Fix warnings, when compiled with -Wshadow
-* Make hiredis compile in Cygwin on Windows, now CI-tested
 * Bulk and multi-bulk lengths less than -1 or greater than `LLONG_MAX` are now
   protocol errors. This is consistent with the RESP specification. On 32-bit
   platforms, the upper bound is lowered to `SIZE_MAX`.
 
+* Change `redisReply.len` to `size_t`, as it denotes the the size of a string
+
+  User code should compare this to `size_t` values as well.  If it was used to
+  compare to other values, casting might be necessary or can be removed, if
+  casting was applied before.
