You've missed 2.5.  In fact, this is borderline between new feature and
bug fix, so you may have even missed 2.6 since soft freeze has already
passed, in which case this should read 2.7.

Thanks for sharing the timeline was not aware of it. I think making changes to
version 2.7 should be fine. However the version string "(since 2.5)" is
part of existing code. I have added a new option "skip-balloon" below it.

MigrationCapability is since 1.2, x-postcopy-ram is since 2.5, and your
addition of skip-balloon is since 2.7.  In other words, when you
copy-pasted x-postcopy-ram's "(since 2.5)" as your starting point for
writing the docs for your new skip-balloon, you need to update the
version in which your new capability is actually exposed.

My apologies, I didn't realize my patch too was adding version string. Will update to version string to 2.7.
