tinc - Apr 2018 - Upgrading 1.1pre14 nodes to 1.1pre15 in an existing mesh

Hi

I have a Tinc cluster of about 100 nodes, and they are all running tinc
1.1pre14.

I'd like to upgrade to tinc 1.1pre15.

Is there a suggested mechanism to do this while keeping the cluster up?
For instance can I simply automate the installation of tinc 1.1pre15 on
each node and reload the existing configuration using 'tinc reload'
Will the temporary state of having a mix set of 1.1pre14 and 1.1pre15 nodes
cause any instabilities?

Any other suggestions or best practices will be very helpful
Thanks

AFAICT "tinc reload" will not restart your process, so you will still
be
running 1.1pre14. You will need to restart tincd to upgrade to 1.1pre15.
This will cause a brief interruption of connectivity (around one second,
typically, depending on setup) for the node that you're restarting.

Not that I know of - 1.1pre14 and 1.1pre15 should be compatible with each
other.
