It's a wrap! Symfony 2.2.0 is now available and this is the first Symfony2 release that was driven by our new release process. First and foremost, I want to sincerely thank the Symfony community (developers, authors, bloggers, speakers, ...) who helped us on this release; everybody did a wonderful job in implementing new features, writing documentation for them, and fixing, tweaking, enhancing our existing code base.

Numbers¶ What can I say about this new release? As planned, Symfony 2.2.0 took 6 months and is made of 711 pull requests containing 2,035 commits and submitted by 44 developers for the code (47,191 additions and 13,512 deletions); documentation enjoyed 1,312 commits by 41 authors (13,038 additions and 3,336 deletions). 2,035 commits on a 6 month period means that, on average, 11 commits were pushed every single day. 711 pull requests means 4 pull requests merged per day.

Documentation¶ The documentation team has been hard at work and all the new features and changes are already documented in the official documentation. It also comes with some nice new cookbooks and chapters.

Upgrading¶ Upgrading from 2.1 to 2.2 should be relatively easy as reported by many developers on the mailing-lists and on Twitter. The first step is to update your composer.json file and run composer.phar update : 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 diff --git a/composer.json b/composer.json index 8f905d7..c2d7588 100644 --- a/composer.json +++ b/composer.json @@ -6,18 +6,18 @@ }, "require": { "php": ">=5.3.3", - "symfony/symfony": "2.1.*", - "doctrine/orm": ">=2.2.3,<2.4-dev", - "doctrine/doctrine-bundle": "1.0.*", + "symfony/symfony": "2.2.*", + "doctrine/orm": "~2.2,>=2.2.3", + "doctrine/doctrine-bundle": "1.2.*", "twig/extensions": "1.0.*", "symfony/assetic-bundle": "2.1.*", - "symfony/swiftmailer-bundle": "2.1.*", - "symfony/monolog-bundle": "2.1.*", - "sensio/distribution-bundle": "2.1.*", - "sensio/framework-extra-bundle": "2.1.*", - "sensio/generator-bundle": "2.1.*", - "jms/security-extra-bundle": "1.2.*", - "jms/di-extra-bundle": "1.1.*" + "symfony/swiftmailer-bundle": "2.2.*", + "symfony/monolog-bundle": "2.2.*", + "sensio/distribution-bundle": "2.2.*", + "sensio/framework-extra-bundle": "2.2.*", + "sensio/generator-bundle": "2.2.*", + "jms/security-extra-bundle": "1.4.*", + "jms/di-extra-bundle": "1.3.*" }, "scripts": { "post-install-cmd": [ @@ -36,9 +36,12 @@ "config": { "bin-dir": "bin" }, - "minimum-stability": "dev", + "minimum-stability": "alpha", "extra": { "symfony-app-dir": "app", - "symfony-web-dir": "web" + "symfony-web-dir": "web", + "branch-alias": { + "dev-master": "2.2-dev" + } } } Then, read the UPGRADE document carefully and do whatever is explained there (you might also need to read the UPGRADE instructions for the Symfony Standard Edition). Optionally, you can also make changes that will make your application more compatible with Symfony 3.0.

Installing¶ If you are starting a new project on Symfony 2.2, based on the full-stack framework, you have several options: Create a new project via Composer ( recommended ): 1 $ php composer.phar create-project symfony/framework-standard-edition somewhere/ 2.2.0 ``

Download an archive for the Symfony Standard Edition; If you are using some of the Symfony components in your new application, just use the 2.2.0 version or the 2.2 branch: Via Composer packages;

Via Github downloads: https://github.com/symfony/{COMPONENT_NAME}/archive/v2.2.0.zip;

Via the PEAR packages (please, do me a favor and upgrade to Composer ;)).
