Hi,

There is a connection to bug#45437, which see.

I agree that it is questionable to go back in time and annotate
all functions with precise information when they had been added.

However, I believe you should
- change your development process such that, in the future, version
  information for functions and variables is recorded
- not ignorantly closing issues such as 45437, when a couple of
  people spent several hours to debug a problem that takes you
  only 5 minutes to fix. Or how long will it take you to add one
  sentence to the documentation of make-temp-file? Or how many
  hours of other people do you want to waste by saving 5 minutes
  on your side?

I now and then contribute to Proof General, which aims to support
about 3 major emacs version. Please advise how one can develop
backward compatible elisp code when the version in the function
documentation is non-present, plain wrong or misleading.

Best regards,

Hendrik
