New submission from Will Bond <will@wbond.net>: When running code on Python 3.8 that previous was running 3.3, I ran into the issue that the default value for the digestmod parameter of hmac.new() has been changed to backwards-incompatible value. I generally would have expected such a break to show up in https://docs.python.org/3/whatsnew/3.8.html#api-and-feature-removals. If not there, somewhere on the 3.8 changelog page. ---------- assignee: docs@python components: Documentation messages: 361329 nosy: docs@python, wbond priority: normal severity: normal status: open title: hmac.new() default parameter change not mentioned in changelog versions: Python 3.8 _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue39547> _______________________________________
