 ### Fixed
 
+* Add compatibility with [requests](https://requests.readthedocs.io)
+  version 2.25 and higher.
+
 ### Misc
 
 * Improve test coverage by running an HTTP server to fake the Patroni API (#55
   by @dlax).
+* Work around old pytest versions in type annotations in the test suite.
+* Declare compatibility with click version 7.1 (or higher).
+* In tests, work around nagiosplugin 1.3.2 not properly handling stdout
+  redirection.
