I’m using Magento 2.4.7-p3. Official doc points to Composer install page which lists all the Composer versions up to the latest (2.8.4 while I’m writing) while Official doc system requirements page says we should use Composer version 2.7 (which is shipped by Ubuntu repositories as well).
Should I use Composer 2.7.1 (shipped now by Ubuntu repository) or Composer 2.8.4 (from the composer install page as linked)?
P.S. I already installed the 2.8.4 version and it seems to work great.
