Goodbye old friend.
The Gigalixir-18 stack has been good to us, but all good things must come to an end. The Gigalixir-18 stack will no longer receive any package or security updates.
Please upgrade your applications to a newer stack to ensure your applications are secure and up-to-date.

Build Type Compatibility
If upgrading to Gigalixir-20 or Gigalixir-22, there should be little concern for build type (mix, distillery, or releases) compatibility.
Beginning with Gigalixir-24, builds default to Elixir Releases and the Distillery build type is no longer supported. See the Gigalixir-24 Announcement for more information.
Performing the Upgrade
To upgrade an existing application to the gigalixir-24 stack, you can run the following command:
gigalixir stack:set gigalixir-24
After setting the stack, you will need to push a new commit to rebuild and redeploy your application to apply the changes. You can revert back through the same process.
We recommend you also clean the build cache when switching stacks:
git -c http.extraheader="GIGALIXIR-CLEAN: true" push gigalixir
