 Changes from 2.8.3 to 2.8.4
 ---------------------------
 
-* **Under development.**
+* Support for Python 3.11 has been added.
+* Thanks to Tobias Hangleiter for an improved accuracy complex `expm1` function.
+  While it is 25 % slower, it is significantly more accurate for the real component
+  over a range of values and matches NumPy outputs much more closely.
+* Thanks to Kirill Kouzoubov for a range of fixes to constants parsing that was 
+  resulting in duplicated constants of the same value.
+* Thanks to Mark Harfouche for noticing that we no longer need `numpy` version 
+  checks. `packaging` is no longer a requirement as a result.
