As we discussed this with @Danylo, milestones may help developers to be 
aware, that their patches were/will be nominated to the next release. 
They will get notification about this and (according to our 
expectations) will review these patches. It is ideal case, for sure, but 
this will prevent such cases as we got recently (when regression was 
found and fixed ASAP, but without any clue that this fix will not be a 
part of the release scope).

As I have access to these labels, that's not a big deal to add not only 
them, but and mark these issues for the future milestone. A bit more 
complicated will be to decide, which issues should be added except 

Aslo, @Mark, in your last reply I saw that you asked about "parsing" 
merge-requests and comments/issues. If I understood the problem 
correctly, you may try my approach.

I am using Thunderbird, and created 2 filters for pattern "Subject 
contains" (doesn't work directly in Gmail filters...) :

1. (#  =>>> this one is parsing Issues and Comments

2. (!   =>>> this one is parsing Merge requests only

On the top of this, I applied filter in Gmail, which is filtering all 
gitlab activity.

And the last thing, as idea - as we know, LunarG and steam/proton team 
have own Ci with lots of traces, and they run them on latest released 
mesa version. As a result, they are reporting us with "hot" issues in 
production - https://gitlab.freedesktop.org/mesa/mesa/-/issues/2823

It would be great to contact them and ask for setting up one more 
instance - which will test our "stable" branch. In this case we will get 
regressions faster and may avoid them in production.
