There's some huge news from the WordPress blog today - an end of life announcement that the popular blogging platform will no longer be supporting PHP4 and MySQL 4.
Our approach with WordPress has always been to make it run on common server configurations. We want users to have flexibility when choosing a host for their precious content. Because of this strategy, WordPress runs pretty much anywhere. Web hosting platforms, however, change over time, and we occasionally are able to reevaluate some of the requirements for running WordPress. Now is one of those times. You probably guessed it from the title '" we're finally ready to announce the end of support for PHP 4 and MySQL 4!
The last version that will fully support PHP4 will be v3.1 and will be released in late 2010. The next version (v3.2) will jump the requirement up to PHP 5.2. According to their statistics, only around 10% of the installs are on PHP4. They also found that less than 6% of users were on MySQL 4. See the full post for complete details.
