Deployments that previously continued with a warning now fail with the following event. <br /><i>Instance deployment: Your 'Gemfile.lock' needs an update but can't be updated because Bundler is running in deployment mode. Regenerate 'Gemfile.lock' with Bundler and redeploy, or set 'BUNDLER_DEPLOYMENT_MODE=false'. The deployment failed.</i> <br />To resolve this, regenerate <code>Gemfile.lock</code> with Bundler and redeploy, or set the <code>BUNDLER_DEPLOYMENT_MODE</code> environment property to <code>false</code>. Ruby 3.3 and Ruby 3.4 aren't affected. </li></ul> </td></tr>
