Versions on published on npm have no corresponding release here

A glaring example is version 17.7.2 from 3 years ago, which has over 50 million downloads, yet no tag or release here. There's not even a 17.x.x branch. Did some branches get deleted in a cleanup? I saw #320 which noted that 13.1.2 was not tagged at that time because it was not common to go back that many releases. This was from late 2020, a couple years before 17.7.2, which indicates that either after this issue tags of new releases weren't always created or tags were deleted. That issue notes that releases were done from the 13.x.x branch, but as noted above, no branch exists for 17.x.x. It does seem odd that the most popular version on npm does not have a corresponding branch here.

There is a tagged yargs 17.7.2 release which may be what you are looking for? There isn't a yargs-parser version 17.7.2.

Yep, thats it. My mistake was in confusing yargs-parser for yargs. Thanks for clearing that up.
