Can we hold onto this release for the time being? There looks to be a couple of other things that could be added to this in the next couple of days, and that would help avoid numerous releases and having to update all the apps again and again.

[andysellick]

Yes, I'd really like to get #1848 and #1764 in if possible - anyone able to review?

[owenatgov]

I'm perfectly fine with this. Let me know when we can put it out. Presumably we'd review if a fix version would still be suitable? Should I close this now just in case?

Let's keep it open for now with a do not merge label - then if it needs closing later we can do that then?

[andysellick]

I've merged #1848

[owenatgov]

@andysellick Did you want to wait until #1764 was merged?

[andysellick]

@owenatgov no that's fine, it's not urgent.

[danacotoran]

@owenatgov we've got a few PR's in Unreleased now, do you want to rebase this and do the honours (unless are we waiting for another merge to happen first)?

[owenatgov]

Ready to roll, just needs an approve and we're good.

[DilwoarH]

@owenatgov - Can we rebase and add this please #1869?

[owenatgov]

@DilwoarH done

[andysellick]

Can we update the PR description to include all the changes in this version?
