Version 2.6.0

Released: 2026-07-21

Changed

• Removed support for EOL heroku-20 builds

Fixed

• Builds that use an in-dyno test database or Redis add-on (heroku-postgresql:in-dyno,
• heroku-redis:in-dyno) could intermittently fail during the pre-build phase with an
• error like The container name "/db" is already in use. These add-on containers now
• start with unique names, so a build no longer collides with a leftover container from
• a previous run.
