This (your second option) is what the stable update guidelines recommend
doing in such a case ("big changes in Electrum 3.0") if possible, but…

… if you can't do the backport in a reasonable time frame (This
vulnerability is very critical, since it allows remote money stealing!), the
recommendation is to just upgrade to the latest upstream immediately (i.e.,
your first option). E.g., this (just upgrade to the latest version, even if
there are breaking changes) is also how Firefox handles security updates.
Upgrading vs. backporting is always a tradeoff. Upgrading keeps you closer
to upstream, backporting means fewer unexpected changes for users of stable
releases. There are instances of both in Fedora, depending on what changed
in the new upstream release and/or how hard it is to backport the security
fixes to the old release.

This (your third option) is the worst possible option. It is better to just
push the new version, which is surely better than nothing (and also better
than doing nothing and letting websites steal the user's money).
