devtools 2.4.3

• New check_mac_release() function to check a package using the macOS builder at https://mac.r-project.org/macbuilder/submit.html (#2375)

• Jenny Bryan is now the official maintainer.

• release() and submit_cran() now record submission details using the Debian Control File format, for better machine-readability. This file has a new name, CRAN-SUBMISSION (instead of CRAN-RELEASE) and now includes package version, in addition to the full SHA and a timestamp.
