Ruby version 3.1.7 is now available (3.1.x is now EOL)

2025-03-26T12:36:32Z

Ruby v3.1.7 is now available on Heroku. To run your app using this version of Ruby, add the following ruby directive to your Gemfile:

ruby "3.1.7"

For more information on Ruby 3.1.7, you can view the release announcement. From Ruby core:

This version is a final release of Ruby 3.1 series. We will not provide any further updates including security fixes for Ruby 3.1 series.

Ruby support for Bundler 1.x re-enabled until April 30th, 2025

2025-03-21T16:08:32Z

Ruby applications using bundler 1.x will resume being able to deploy effective immediately until April 30 2025. This update changes behavior rolled out on March 19th, 2025.

On March 19, 2025, Heroku changed the heroku/ruby buildpack’s default Ruby version which prevented the evaluation of gems with Bundler 1.x. This version of Bundler was last released in December 2018 and is not receiving support from Bundler Core. That means Bundler 1.x will not work with Ruby 3.2 or 3.3 due to an error:

remote:  !     There was an error parsing your Gemfile, we cannot continue
remote:  !     /tmp/d20250319-150-o0ictl/bundler-1.17.3/gems/bundler-1.17.3/lib/bundler/shared_helpers.rb:29:in `root': undefined method `untaint' for an instance of Pathname (NoMethodError)

While the vast majority of applications on the platform use a modern version of bundler, it’s more likely that applications still trying to migrate off of heroku-20 are using bundler 1.x of those applications, Rails 5.x apps can easily upgrade to bundler 2.3.27 while Rails 4.x applications are hard locked to bundler 1.x. While technically that also means they’re using Unsupported Ruby versions, we felt that delaying the rollout of this internal Ruby upgrade (which is at the root of the bundler 1.x limitation) would help customers in their upgrade process.

We strongly recommend that customers upgrade their application to a non-EOL version of Ruby and Rails. For the highest levels of stability and security, we recommend staying on the latest Ruby, Rails, and Heroku stack.

Bundler 1.x will no longer work on Heroku after April 30, 2025

Customers using Bundler 1.x after April 30, 2025, will see an error message when deploying and are encouraged to upgrade to Bundler 2.3.27. To prevent this error, upgrade your bundler version as soon as possible. Run:

If you’re limited to bundler 1.x due to a dependency on rails, this post has some suggestions that may help Upgrading Ruby versions to run on Heroku-24 .

$ gem install bundler -v 2.3.27
$ bundle update --bundler

Verify that the correct version is listed in the Gemfile.lock:

$ cat Gemfile.lock | grep "BUNDLED WITH" -A2
BUNDLED WITH
   2.3.27

And check the results into git:

$ git add Gemfile.lock
$ git commit -m "Update bundler version to 2.3.x"

Bundler 1.17.3 was last released on December 27, 2018, and is no longer supported by bundler/rubygems core. The exception occurs because the heroku/ruby buildpack uses ruby. It invokes bundle platform --ruby to determine what Ruby version the application needs. The version of Ruby the buildpack uses is incompatible with the version of bundler requested by the application.

Router 2.0 is now the default for all new Eco-tier Applications

2025-03-20T15:13:09Z

Router 2.0 is the new Common Runtime router, replacing the legacy router. It is now the default for all new Eco-tier applications. Basic, Standard and Performance-tier applications will continue to run on the legacy router until the tier-specific end-of-life date for the legacy router found in the link below.

See the Legacy Router end-of-life FAQ Help article for updates on timelines and information.

Java 24 now available

2025-03-19T18:00:06Z

Heroku’s support for Java, Scala, Clojure, and Gradle now includes support for OpenJDK version 24. To use this version of the JDK, create a system.properties file in your application with the following contents:

java.runtime.version=24

After your next deployment, Heroku will install and run your app with OpenJDK 24. For more information, see the article on Heroku Support for Java in the Dev Center. For more information on JDK 24, see the official OpenJDK documentation.

Default Ruby version for new apps is now 3.3.7

2025-03-19T14:28:07Z

The default Ruby version for new Ruby applications is 3.3.7. You’ll only get the default if the application does not specify a ruby version.

Ruby applications with no specified bundler versions now receive Bundler 2.3.x. Bundler 1.x will no longer work.

2025-03-19T14:27:20Z

Update (March 21, 2025): Bundler 1.x will now work on the platform until April 30, 2025. We still highly recommend upgrading bundler versions as soon as possible. The directions below have been updated from their original wording.

Previously applications with no BUNDLED WITH in their Gemfile.lock would receive bundler 1.x. They will now receive the new default bundler version 2.3.x.

It is strongly recommended that you have both a RUBY VERSION and BUNDLED WITH version listed in your Gemfile.lock. If you do not have those values, you can generate them and commit them to git:

$ bundle update --ruby
$ git add Gemfile.lock
$ git commit -m "Update Gemfile.lock"

Applications without these values specified in the Gemfile.lock may break unexpectedly when the defaults change.

Bundler 1.x will no longer work on Heroku after April 30th.

If you’re limited to bundler 1.x due to a dependency on rails this post has some suggestions that may help Upgrading Ruby versions to run on Heroku-24 .

Customers using Bundler 1.x will see an error message when deploying and are encouraged to upgrade to Bundler 2.3.27. To fix upgrade your bundler version. Run:

$ gem install bundler -v 2.3.27
$ bundle update --bundler

Verify that the correct version is listed in the Gemfile.lock:

$ cat Gemfile.lock | grep "BUNDLED WITH" -A2
BUNDLED WITH
   2.3.27

And check the results into git:

$ git add Gemfile.lock
$ git commit -m "Update bundler version to 2.3.x"

Upgrading your application Bundler 2.3.x+ fixes the exception. For more information see Ruby support for Bundler 1.x re-enabled until April 30th, 2025 published March 21, 2025.

Default app domain name and DNS targets updated for Fir-generation apps

2025-03-12T20:01:33Z

Heroku has implemented improvements to DNS management for the Fir-generation, and all new Fir apps utilize sharded DNS zones which will have the new domain format of the following: <haiku>.<regional-haiku>.herokuapp.com. For example:example-app-1234567890ab.redwood-oregon.herokuapp.com

Similarily, Fir Private Spaces apps now use <haiku>.<regional-haiku>.herokudns.com for DNS targets.

While your app is available at your default domain, we strongly recommend adding a custom domain to production apps. You can view your updated DNS targets with the heroku domains command. See View existing domains for details.

Heroku-20, Heroku-22 and Heroku-24 stacks updated

2025-03-11T15:49:54Z

We updated the heroku-20, heroku-22 and heroku-24 stacks to pick up security fixes in upstream packages. The new base images for each stack roll out automatically to the Common Runtime over the next 48 hours, followed by Private Spaces.

If you use Heroku’s default buildpack-powered build system/stacks, you don’t need to redeploy your app to include these changes. We automatically restart any running dynos as we roll out the new base images for each stack. For Cedar-generation apps, each time a dyno starts, the slug applies on top of the most recent base image. For Fir-generation apps, the built image gets rebased on top of the most recent base image.

If your app uses Heroku’s container stack (most don’t), you must rebuild your app’s Docker image to pick up updates in the base image specified in your Dockerfile.

See this Dev Center article for an overview of the packages available in each stack’s base image.

The Heroku-20 stack is deprecated and will reach end-of-life on April 30th, 2025. Upgrade to a newer stack as soon as possible. See the Heroku-20 End-Of-Life FAQ for more details.

Heroku-20, Heroku-22 and Heroku-24 stacks updated

2025-02-24T17:02:49Z

If your app uses Heroku’s container stack (most don’t), you must rebuild your app’s Docker image to pick up updates in the base image specified in your Dockerfile.

See this Dev Center article for an overview of the packages available in each stack’s base image.

The Heroku-20 stack is deprecated and will reach end-of-life on April 30th, 2025. Upgrade to a newer stack as soon as possible. See the Heroku-20 End-Of-Life FAQ for more details.
