devtools::release() works by asking the user a number of yes/no questions. By default those are

• Have you checked for spelling errors (with spell_check())?
• Have you run R CMD check locally?
• -- Running additional devtools checks for -----------------------------------------------------------
  \<checks here>
  -------------------------------------------------------------------------------------------------------------
  Were devtool's checks successful?
• Have you fixed all existing problems at https://cran.rstudio.com//web/checks/check_results_.html ?
• Have you checked on R-hub (with check_rhub())?
• Have you checked on win-builder (with check_win_devel())?
• Have you updated NEWS.md file?
• Have you updated DESCRIPTION?
• Have you updated cran-comments.md?
• Is your email address \<package creator email>?

More questions can be added by adding a non-public release_questions function to the package.

While automating most of those steps is possible, the release function itself gives 3 random choices for answers with only one affirmative, making it impossible to automate running it.

After the user gives a positive answer to all questions, it then calls devtools::submit_cran(), but that call failed for me, so I don't know what it exactly does.
