Could you add an alias to experimental.updatecheck so old configurations will not break. I'm not saying to keep it forever but at least have it when we change it.

+1 on documenting the option now that it's not experimental anymore

I'm not crazy about the code style. But since this code only lives for a release, I'm OK taking it. I'll accept this but will defer to someone else to queue it in case there are strong opinions about the style.

How do you feel about this alternative approach?

updatecheck = ui.config('commands', 'update.check')
if updatecheck is None:
    updatecheck = ui.config('experimental', 'updatecheck')
if updatecheck not in ('abort', ...):

Sorry, I was not clear, I was thinking about adding an alias in the config registration, like that:

coreconfigitem('commands', 'update.check',
    default=None,
    alias=[('experimental', 'updatecheck')]
)

Should I send a follow-up?

Ugh, please send a follow-up, sorry about that.

Determines what level of checking :hg:`update` will perform before moving

``linear``, and ``noconflict``. ``abort`` always fails if the working
directory has uncommitted changes. ``none`` performs no checking, and may
result in a merge with uncommitted changes. ``linear`` allows any update
as long as it follows a straight line in the revision history, and may
trigger a merge with uncommitted changes. ``noconflict`` will allow any
update which would not trigger a merge with uncommitted changes, if any
are present.
