I have a question regardin those 'Models' and Dashboard filters:
Is it correct, that you are now able -->to write a native sql question --> convert it to a model --> and using any field in a Dashboard as a filter without setting a parameter within the sql code ?
If this is correct, what do we have to consider to make it work?

Thank you for your kind explanation @flamber I understand the motivation behind.
But I am not sure to grab the last part. Do you hint that we can still use the metabot on Slack ? It looks like it is disabled since the migration to version 0.42
@mazzma12 MetaBot is completely removed. There's no MetaBot code anymore.
Again, just so there isn't any misunderstandings on what exactly MetaBot is; it's the functionality that you probably didn't use, where you could write commands from within Slack like @metabot question 123
https://www.metabase.com/docs/v0.41/users-guide/11-metabot.html
It has absolutely nothing to do with Metabase sending Subscriptions/Pulses/Alerts to Slack, which is still supported.

We also ran into some issues with the new Slack App. Maybe someone can help us on that:
It seems that new private channels don't appear in the channel search when creating Alerts or Dashboard Subscriptions. There are some old private ones from our previous slack bot integration. However, new ones don't show up. We tried adding the App to the channel as well as the old Slack bot.
Did someone encounter similar issues or is there a solution for it?
I am assuming that it has to do something with the permission scope. We added group:read but that also did not fix it.
@Somtom It seems like we're only retrieving the public channels:
https://github.com/metabase/metabase/blob/master/src/metabase/integrations/slack.clj#L156
So I'm unsure how you are seeing some old private channels, since those should have been expunged on restart. Not quite if this is intended or a limitation of how the App works.
Wow that was a quick reply thanks!
Let me take that on the old channels back actually. I miss interpreted one channel name. In our case it was actually nice to be able to use private channels as well in the past. Haven't done a lot of clojure yet, but I would be happy to contribute in case that is an easy thing.
@Somtom I don't know what it would take, but likely including private channels in the filter, but also permissions, so they're even retrieved from Slack. Then I don't know what would be required beyond that. In other words, I don't think it would be simple and there's several caveats and would require tests too.
Guys, I'm using Metabase Cloud and my account seems not upgrade to the latest version. In "Setting > About Metabase" it says that I'm on version 1.41.6
What should I do to upgrade on 1.42 version?
