UPSTREAM_CHECK_COMMITS variable doesn't appear in the documentation, and it's in relatively frequent use. Proposing to add a description based on the initial commit for UPSTREAM_CHECK_COMMITS (https://git.openembedded.org/openembedded-core/commit/?id=591d57877d3d3e659d78c0ed33f4c515e3f6f8fb)?
Adding a comment from Alex Kanavin: That would be very useful, but you should check if the entire nomenclature of UPSTREAM_CHECK_* variables is documented as well (_COMMITS, _REGEX, _URI, _GITTAGREGEX).
*** Bug 14545 has been marked as a duplicate of this bug. ***
Currenly working on updating the related documentation, but looking at the code, UPSTREAM_VERSION_UNKNOWN should be documented as well.
Fixed upstream since http://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/commit/?h=master-next&id=034b976addd0db6da31c4bacdbea21f2d47c00dc
