Version 4.0.5

Release Date: January 31, 2021

4.0.5 release of CodeIgniter4

Enhancements

  • New URL helper function url_to() which creates absolute URLs based on controllers.
  • New Model option: $useAutoIncrement which when set to false allows you to provide your own primary key for each record in the table. Handy when we want to implement a 1:1 relation or use UUIDs for our model.
  • New URL helper function url_is() which allows you to check the current URL to see if it matches the given string.
  • Services now have their config parameters strictly typehinted. This will ensure no one will pass a different config instance. If you need to pass a new config with additional properties, you need to extend that particular config.
  • Support for setting the SameSite attribute on Session and CSRF cookies has been added. For security and compatibility with the latest browser versions, the default setting is Lax.
  • Guessing file extensions from mime type in Config\Mimes::guessExtensionFromType() now only reverse searches the $mimes array if no extension is proposed (i.e., usually not for uploaded files).
  • The getter functions for file extensions of uploaded files now have different fallback values (UploadedFile::getClientExtension() for UploadedFile::getExtension() and '' for UploadedFile::guessExtension()). This is a security fix and makes the process less dependent on the client.
  • The Cache FileHandler now allows setting the file permissions mode via Config\Cache.

Changes

  • System messages defined in system/Language/en/ are now strictly for internal framework use and are not covered by the backwards compatibility (BC) promise. Users may use these messages in their applications but at their own risk.

Bugs Fixed

  • Fixed a bug in the Entity class where declaring class parameters was preventing data propagation to the attributes array.
  • Handling for the environment variable encryption.key has changed. Previously, explicit function calls, like getenv('encryption.key') or env('encryption.key') where the value has the special prefix hex2bin:, returned an automatically converted binary string. These calls now return the character string with the prefix. This change was due to incompatibility with handling binary strings in environment variables on Windows platforms. However, accessing $key using the Encryption class config remains unchanged and still returns a binary string.
  • Config\Services (in app/Config/Services.php) now extends CodeIgniter\Config\BaseService to allow proper discovery of third-party services.
