SNAPD out of date

[Bob]

On 5 Aug I upgraded Ubuntu 17.10 to 18.4.  During the upgrade I got a popup
that said SNAPD was out of date, I replied to continue the upgrade.

I have no idea what SNAPD is or does.
Why was SNAPD not up to date as I apply all changes when I get notified there
are updates available?

After the upgrade I checked the SNAPD version.

robert at MARS:~$ apt list snapd
Listing... Done
snapd/bionic-updates,now 2.34.2+18.04 amd64 [installed]
N: There is 1 additional version. Please use the '-a' switch to see it
robert at MARS:~$ apt -a list snapd
Listing... Done
snapd/bionic-updates,now 2.34.2+18.04 amd64 [installed]
snapd/bionic 2.32.5+18.04 amd64

So if there is a newer version why is not installed?

This is all very confusing.
