4.0.0

Added

• Upgrade guide: Upgrading from 3.x to 4.0
• Support for PHP 8.1 and up.

Changed

• Lots of internals upgraded:
  • Symfony 5.4.
  • PHPUnit 9.x.
  • Code coverage reporting.
  • Psalm level 2 compliance.
  • PSR-12 compliance.
• Small changes to documentation towards prioritise GitHub Actions over Travis CI.
• In addition to the internal and doc changes above, this initial 4.x release has 100% feature-parity with current 3.x series, setting the base for further improvements and new features. No changes are expected in general, other than in order to meet the new requirements.

Removed

• Support for PHP < 7.4 (the new minimum version).
• Support for Moodle < 3.8.3, that was the first release officially supporting PHP 7.4.
