v5.0.0

heroku/ruby

Changed

• Default Ruby version is now 3.2.6 (#374)
• Default Bundler version is now 2.5.6 (#374)

v4.0.2

heroku/ruby

Fixed

• Ruby pre-release verssions like 3.4.0.rc1 now work as expected. (#372)
• Layer metadata deserialization to Rust structs is now using #[serde(deny_unknown_fields)] this prevents the accidental scenario where metadata containing a superset of fields could accidentally be deserialized to the wrong struct. It's unlikely this is currently happening with the current buildpack, but it's a possibly-observable difference so it's being listed (#371)

v4.0.1

heroku/ruby

Fixed

• A bug introduced in 4.0.0 would result in incorrectly skipping running bundle install when the Gemfile or Gemfile.lock or environment variables had changed. The bug is now fixed. (#364)

v4.0.0

heroku/ruby

Changed

• Default process types defined by the Ruby buildpack now use IPv6 host :: which is equivalent of IPv4 host 0.0.0.0. This will only affect applications that do not define a web process type via the Procfile and Procfile Cloud Native Buildpack. Those applications must make sure to update their configuration to bind to an IPv6 host. (#354)

Added

• The buildpack now warns the user when environmental variables used in running the default process are not defined. (#307)

v3.0.0

heroku/ruby

Changed

• The buildpack now implements Buildpack API 0.10 instead of 0.9, and so requires lifecycle 0.17.x or newer. (#283)

Added

• Added support for Ubuntu 24.04 (and thus Heroku-24 / heroku/builder:24). (#284)

v2.1.3

heroku/ruby

Changed

• The fun_run commons library was moved to it's own crate (#232)

Added

• Raise a helpful error when a file cannot be accessed at the time of buildpack detection (#243)

v2.1.2

heroku/ruby

Fixed

• Update build logging style (#198)

v2.1.1

heroku/ruby

Fixed

• Updated buildpack display name, description and keywords. (#223)

v2.1.0

heroku/ruby

Added

• Introduce heroku build metrics support (#172)
• Changelog moved to be per-crate rather than for the whole project (#154)

v2.0.1

heroku/ruby

• Commons: Introduce build_output module (#155)
• Commons: Remove gem_list, rake_status, rake_task_detect modules (#155)
• Commons: EnvCommand removed, replaced with fun_run (#139)
