I think we need to internationalise these emails in general.

[femaref]

I think this should be backported, as it's a small, but highly impactful quality of life fix. we are working in a larger team, as such the throughput can be quite high. right now, I have to open every email to see if the ticket was closed or if it's a new ticket/comment. this is quite annoying and having to tell my team it will take some time until this stops isn't something I'm looking forward to.

[zeripath]

Seems reasonable to me that this could be backported. @lunny can we send a backport?

[lunny]

@zeripath done.

[zeripath]

@femaref The backport is in our release/v1.8 branch now.

[femaref]

thank you. are there builds available before they are released as rc? or do I have to build it myself?
