• #3554307: Branch 11.3.x and Remove alpha experimental code from the 11.3.x codebase.
• Tag 11.3.0-alpha1.
• Commit #3552922: Add symfony/runtime dependency to core to 11.x.

    • Split out additional bugs and deprecations as needed for issue management.
    • Attempt to resolve these prior to 11.3.0-beta1 and 10.6.0.-beta1 and treat them as beta blockers.
  • For rc1/stable release: Update to Symfony 7.4.0 as soon as it is available, including addressing most or all of the above blockers.
