The push upgrade to all 9.20 Production orgs will be scheduled for after 6 pm Pacific on February 6th, 2020.
Quotes 9.21 will include features and fixes. Release Notes will be available soon with details.
Yep, as chdavid said! We were updated on Friday morning, but still no indication of what's changed.
I've said it before, but release notes should be published *before* a release so we know areas that have changed and can keep an eye out for any issues/plan for changes we may need to make in tandem. Having them appear (as is usual) at the same time as a release is irritating but tolerable, but to still be in the dark several days later is just poor.
The release notes are now online and can be seen here.
Thanks for your patience,
