After an upload two weeks ago and a full suite of manual verification testing, the first round of Stable Release Updates of cloud-init 19.1 have been released to all stable Ubuntu releases in standard support. For more details of what changes are included in these updates, see the changelogs for the Ubuntu packages (which can readily be accessed here). Particular thanks go to @chad.smith for driving this SRU process to completion!
If the new versions of cloud-init cause you any problems, please don’t hesitate to file a bug on Launchpad.
On behalf of the cloud-init team, thanks!
