As announced on the Symfony project's blog today, they are officially announcing the last release of the 1.0 series in favor of the 1.4 releases.
The 27th of January is kind of an important date in mankind history. Of course, everybody know it is the birthday of Wolfgang Amadeus Mozart and the date of the invention of the light-bulb by Thomas Edison. To this list, the core team is proud to add the last release of the symfony 1.0 branch: symfony 1.0.22.
It's been three years since the first release in the 1.0.x series was made and a lot of progress has come along since then (including a few other branches) including over 163,000 lines of code, 22 stable releases and more than 300 plugins. You can grab the latest from their 1.4.x series (currently 1.4.1) from thier download page either as a package or as a checkout from their Subversion repository.
