Yii3 Roadmap

Last updated: 02.10.2025

The Yii3 release is approaching, and the team is working hard to complete the final steps 💪.

At the heart of Yii3 are its packages, which form the foundation of the framework. So far, 109 packages have been released, and the remaining ones are already 80-90% complete. But Yii3 is more than just its set of packages. It also includes great documentation and ready-to-use application templates. Completing these elements is a key part of preparing for the final release.

You can support the Yii3 team and help accelerate the release by making a donation. Every contribution, no matter the size, helps us move closer to delivering Yii3:

	// secure hashing of passwords using bcrypt, needs PHP 5.3+
	// see http://codahale.com/how-to-safely-store-a-password/

	// salt for bcrypt needs to be 22 base64 characters (but just [./0-9A-Za-z]), see http://php.net/crypt
	$salt = substr(strtr(base64_encode(openssl_random_pseudo_bytes(22)), '+', '.'), 0, 22);

	// 2y is the bcrypt algorithm selector, see http://php.net/crypt
	// 12 is the workload factor (around 300ms on my Core i7 machine), see http://php.net/crypt

	function weighted_average($values) {
	$sum = 0;
	foreach ($values as $i => $value) {
	$sum += $value;
	}

	$avg = $sum / count($values);

	$error = array();
