• SBT can be updated to 1.7.2 in project/build.properties
• Dependencies uk.gov.hmrc.bootstrap-frontend-play-28 in project/AppDependencies.scala and uk.gov.hmrc.bootstrap-test-play-28 in project/AppDependencies.scala should be the same version - consider using a shared variable
• Please remove ExecutionContext.Implicits.global from app/uk/gov/hmrc/helpfrontend/controllers/HelpController.scala - ExecutionContext should be injected otherwise MDC logging will be broken
• There is a bobby warning (builds will be prevented after 31 Mar 2023) - see the pr builder for details
