Hi there,
At the Backdrop Summit, it came up that you guys deploy patches to Backdrop on Pantheon. I went there today to spin up a Backdrop test site, and it wasn't among the options for what you can install. It doesn't seem to be in the documentation, either; there's a page on start states where you can click a link to spin up a Drupal distro, but no Backdrop.
Is there a workaround I'm missing?
Thanks!
You need to click from the backdropcms.org site rather than that page. Pantheon no longer displays any of the custom upstream on the page you show. Backdrop has the custom upstream status but is getting help from Pantheon staff to ensure it works.
