Just two days after the first alpha release of symfony 1.3, I'm proud to announce that both the Practical symfony book (aka the Jobeet tutorial) and the symfony reference guide have been updated to take into account the new features of this version of symfony.
For instance, you can start using the new mailer feature of symfony 1.3 by reading day 16 of Jobeet, and learn about all its configuration possibilities by digging through the factories chapter of the reference guide.
Even if symfony 1.3.0 alpha1 has just been released, you already have access to a lot of up-to-date documentation:
Getting Started: This tutorial is the best way to get started with symfony. It explains everything you need to know about symfony installation. In a matter of minutes, you will be ready to use symfony and start your next project.
What's new?: If you have already used symfony before, discover all the new features and enhancements of symfony 1.3.
Upgrade to 1.3: If you already have some projects done in symfony 1.2 and want to upgrade them, this is where you can read about what need to be changed.
Deprecated in 1.3: As you might know, symfony 1.4 will be the next LTS (Long Term Support) release. If will be the same code base as symfony 1.3 with all the deprecated features removed. Learn about what is deprecated in this document.
The symfony Reference Book: The Symfony Reference Guide is a book where you can easily find answers to your questions at your fingertips. This is a book you will keep with you whenever you develop with symfony.
It means that we have plenty of documentation whether you want to discover symfony 1.3 or switch from a previous version.
All in all, symfony 1.3 already has more than 650 pages of documentation.
