Yes, the wire protocol is the same. The 1.5.x server will just ignore
tickets and treat the access.request command as a NOOP.

Although the 1.4 client will work, there are a number of bugs that
have been fixed in the 1.5.x client, especially surrounding edge cases
with the shutdown protocol. Hence if you do have any issues with it,
our first repsonse is likely to be "upgrade to the latest stable
version". If you do have the time to retest your application, it may
be worth upgrading before you go into prod.
