Sorry upfront as this is going to be a bit of a rambling question.
Today I was creating a package using 2nd Generation packaging and as part of my process I install the new package into a test scratch org to see that it installs smoothly. I noticed that the install process seemed to be taking much longer than usual, so I opened up the scratch org and wanted to look around. Clicking on the Service app, I noticed the logo was this:
This is usually bad news, as all my packages that I will create / promote could also be on Winter '21 as well.
I tried to install the package that I promoted today into a normal Salesforce org, and I got a "Mismatching Versions" error, which I believe is the error we get when our packaging / dev orgs are ahead of our client orgs.
My DevHub org is still on Summer '20, so I think it's just the packaging process that's been affected. I'm not sure if I possibly have a plugin that's messing up, but this is what I see when I run a sfdx plugins
salesforcedx 49.5.0
├─ salesforcedx-templates 49.2.0
├─ custom-metadata 1.0.8
├─ @salesforce/sfdx-plugin-lwc-test 0.1.7
└─ salesforce-alm 49.5.0
I tried to add a "release":"previous"
entry into my Scratch org config file, but I get an error
At this time, we are outside of the preview period. You can create only current release scratch orgs.
Anyone else experiencing this, and hopefully know of a work around?
To be clear, it seems I'm getting Winter '21 orgs today, when I shouldn't be able to. Is there any way to force sfdx to use Summer '20 in both org creation and, more importantly, package creation?
