I wasn't paying close attention when we discused Terraform updates on
IRC the other day, and I assumed all the updates to Terraform was done
with last year's news in mind, but I see now the proposed update is to
1.8.5.
Terraform releases after 1.5.7 are NOT free software (or open source).
They are available ONLY under Hashicorp's proprietary terms. See
https://www.hashicorp.com/license-faq for details. It seems that
eventually four-year-old versions of Terraform post-transition will
begin to be released as free software (mpl-2.0) but that won't affect
1.8.5 until the year 2028.
