Pimcore Symfony Freeze

A metapackage to control Symfony version constraints for Pimcore 12.3 and 12.x development versions.

⚠️ Important: This package is only for Pimcore 12.3 and 12.x dev versions. Pimcore 13 will require Symfony 7+ and drop Symfony 6 support entirely.

Purpose

This metapackage uses Composer's conflict directive to enforce Symfony version requirements:

• 6.x branch: Freezes core Symfony components at 6.x (14 components)
• 7.x branch: Requires core Symfony components at 7.x minimum (13 components)

Usage by Pimcore Version

Pimcore 12.3 / 12.x (dev versions)

Symfony 7.x fully supported - choose based on your needs:

{
  "require": {
    "pimcore/symfony-freeze": "^7.0" // Recommended: Enforce Symfony 7.x minimum
  }
}

Or if you need Symfony 6.x compatibility:

{
  "require": {
    "pimcore/symfony-freeze": "^6.0" // Optional: Keep Symfony 6.x
  }
}

Pimcore 13+

Do not use this package. Remove it:

composer remove pimcore/symfony-freeze
