The new issue view for Jira Cloud is coming for full-page issues

[Mike]

Yesterday evening we received an email from Atlassian stating the roll out of the new issue view will happen in the coming weeks.  Our organisation relies on the old issue view due to integrations such as TestRail not working with the new issue view and TestRail doesn't have this on their backlog either to integrate.  Because of this lack of integration we decided not to roll out the new view to our engineering teams.

My question is this.

Will the old view still be available and supported by Atlassian? 

If so, for how long approximately?

[Mike]

It appears somewhere between last week and this week, this has now been exposed on the new issue view screen.  Only 9 days ago the gurock peeps hinted this wouldn't be supported in the near future.
