The remote/manual check passed with 0 errors, 0 warnings, and 0 notes. The R-devel Win-builder check has been submitted and is waiting for the result email.

I am deferring the cloud reverse-dependency check until Rapp 0.4.1 reaches CRAN. Running it against the current CRAN Rapp 0.4.0 would report the snapshot mismatch already fixed in r-lib/Rapp#41.

yaml12 is already version 0.2.0. Do not run the generated use_version('minor') command when resuming the checklist; it would advance the package to 0.3.0. Mark that item complete when the release reaches the submission stage.
