Dialog with version details:

@teon i propose to use the same format we have for wizards but change the side image style - so it looks different from the wizards. + i added badge in case of Urgent updates

[teon]

@Va1ter this is ok - that's the details dialog - but where is the "Call to action" - how admin will be notified about the update in the UI? Where should he/she click to see this screen?

@teon we have predefined toast-notification view for this case
