No blackfire or newrelic extension builds yet with support for 8.4. The phalcon extension is incompatible with 8.4 (they always get new releases some time later), and pcov needs a fix and release first: https://github.com/krakjoe/pcov/pull/111. The imap extension has moved to PECL.
The heroku-20 stack is not getting this version because the stack is already deprecated.
