Oh Yes! Thanks!
Awesome job, thank you all!
The Symfony installer still installs Symfony 3.2.9:

$ symfony new Symfony

✔ Symfony 3.2.9 was successfully installed. Now you can:

* Change your current directory to /home/eric/Documents/Symfony
* Configure your application in app/config/parameters.yml file.
* Run your application:
1. Execute the php bin/console server:run command.
2. Browse to the http://localhost:8000 URL.
* Read the documentation at
Awesome job people! I've been looking forward for this release!!! Tnx Fabien.
Thank u !
@troudbal should be fixed now - I think there was some delay in the Symfony installer's tar :).
Awesome job ...
Thanks !
I guess that would be useful if release notes will be sorted by issue type, severity\priority and component
It looks good, but the LdapClient seems to be broken from a default install. It reports a circular reference to itself.

You can reproduce the behavior by doing a default install and then adding the LdapClient part from here to your services.yml file
