Version 4.7.3

Release Date: Unreleased

4.7.3 release of CodeIgniter4

BREAKING

Commands: The -h option for the routes command is renamed to --sort-by-handler to avoid conflict with the common use of -h as a shortcut for --help. The old -h option will continue to work until v4.8.0, at which point it will be removed and repurposed as a shortcut for --help. A warning message is displayed when using the old -h option to encourage users to switch to the new --sort-by-handler option.

Autoloader: Fixed a bug where Autoloader::unregister() (used during tests) silently failed to remove handlers from the SPL autoload stack, causing closures to accumulate permanently.
CLI: Fixed a bug where CLI::generateDimensions() leaked stty error output (e.g., stty: 'standard input': Inappropriate ioctl for device) to stderr when stdin was not a TTY.
Commands: Fixed a bug in the env command where passing options only would cause the command to throw a TypeError instead of showing the current environment.
Common: Fixed a bug where the command() helper function did not properly clean up output buffers, which could lead to risky tests when exceptions were thrown.
Entity: Fixed a bug where Entity::normalizeValue() did not handle UnitEnum before checking for toArray(), causing enums implementing toArray() to be incorrectly normalized as generic objects instead of enums.
Validation: Fixed a bug where Validation::getValidated() dropped fields whose validated value was explicitly null.

See the repo's CHANGELOG.md for a complete list of bugs fixed.
