What did not change is that there is a need for a solid development framework and our dedication to making Yii 3 happen. I'm glad you are supporting us despite the situation.

Stay healthy and enjoy reading.

Thank you!

🔷 Yii 2

Version 2.0.33 was released with 22 issues fixed and 4 enhancements added.

Additionally, the following extension releases were made:

• Shell 2.0.3
• Twig 2.4.0
• Redis 2.0.12
• Gii 2.2.0

🔶 Yii 3

To have a better picture of what happens and what's to be done we've created a Trello board.

• First package from Yii 3 got 1.0.0 version tag. That is a friendly exception. Not a huge deal but it is a start.
• Composer config plugin is now part of yiisoft.
• Composer config plugin build directory was moved into application runtime for better visibility.
• A project to port database abstraction layer and active record from Yii 2 was moved forward very significantly so the chance that we'll see it as a separate package is bigger than ever.
• Big progress on yiisoft/yii-queue package.
• DI container got proxies with the help of yiisoft/proxy and yiisoft/container-proxy.
• DI container was cleaned up and now provides less public methods. API got a bit simpler.
• The collector part of the debugger package progressed significantly. It is way handier than in Yii 2 in terms of helping you with collecting the data you need. With the help of a proxy container, it may capture any service methods.
• Gii progressed well.
• Validator package got skipOnError, ability to translate messages, immutable rules and conditional validation.
• Aliases package ability not to throw an exception on non-existing alias was removed.
• Thin file system abstraction package was introduced.
• More tests were added to yii-web package.
• VarDumper was refactored.
• Router got additional polishing.
• REST package got some initial implementation. Parts of it may be moved to yii-web later.
• The Emitter was moved out of the application to index.php.

🔷 Yii 2

• simialbi contributed code for switching Yii 2 testing from Travis to Github actions. It resulted in way better build times for both commits and pull requests. The drawback is that it is not as stable as Travis was: occasional segfaults, failure to start a service etc. so we're going to keep it to Yii 2 and watch it for now. After it stabilize, Yii 3 packages are going to be switched to it.
• haveyaseen patched PHPUnit to fully support PHP 5.4 — 7.4 producing no warnings when running tests.
• Codeception Yii 2 module was updated to support Codeception's multisession.
• Twig extension versions 2.2.2 and 2.3.0 were released.
• Auth client extension 2.2.7 was released.
• Apidoc extension 2.1.3 was released.
• Sphinx extension 2.0.13 was released.

🔶 Yii 3

That's not complete list of changes since amount of pull requests was overwhelming!

• Widget package was extracted from view and finally took its shape.
• Some standard Yii widgets were implemented and ended up in yii-widgets package.
• Initial implementation of Bootstrap 4 was done.
• We've switched automatic style corrections made via StyleCI to PSR-12.
• Almost all packages got typed properties.
• Validator package got polished.
• Both Cylce integration package and Cycle ORM itself were further developed. ORM became more performant, integration was refactored, got cycle/schema command, SelectDataReader (implementation of "data" interface), ability to define schema in a PHP file instead of annotations. Docs were written.
• Router package was modified heavily. In addition to refactoring, partial re-implementation and bugfixes, it got ability to generate absolute URLs, better syntax, proper middleware stacking, lazy initialization and significant performance boost.
• RBAC package got refactoring.
• i18n got message formatter implemented. Translator was moved to separate package.
• Work on queue package started.
• Data package offset paginator was adjusted based on real experience using it.
• Dependabot was added to Yii 3 repositories, all dependencies were updated.
• Dataview package (lists and grids) was developed further.
• Arrays package got important fixes both new and ported from Yii 2.
• DI container got important fixes. Deferred service provider now has to explicitly list IDs of services provided.
• Some classes were removed from web package: Chain middleware, action caller middleware, callback middleware. All these are now natively supported by the router.
• Middleware dispatcher was reworked to properly stack middleware. All potentially dangerous use-cases were ensured not to be possible anymore.
• Web application started to raise events on initialization, shutdown and request processing start/end.
• Demo application got better syntax for view rendering.
• Yii 2 DB abstraction, driver implementations for PostgreSQL, MySQL, SQLite and Active Record got initial working ports to Yii 3. These are far from production quality but it is an important step towards possible standalone implementation.
• Debugger design draft was composed, implementation started.
• Event dispatcher got concrete events provider.
• Yii demo got Docker support fixed and was transformed into a blog example. It is currently extensively using Cycle ORM, Bootstrap 4 and data package. There you can see how the application could be currently developed using Yii 3. But please note that it definitely does not resemble final version. Feedback on it is more than welcome at both official forum and issue tracker.

📙 New and adjusted internal guidelines:

• Exceptions.
• Tests.
• Code review.
• Documentation.

📙 New guide pages:

• Console applications.

⚠️ Don't try it at home ;)

There are adventurous people who are developing first projects with Yii 3 and even deploying production instances. Even with all the harsh edges of pre-alpha, feedback is that the development process is mostly more enjoyable than Yii 2. That's a good sign.

Here's some reading that resembles the spirit of Yii 3 well:
