Just ten days after releasing version 2.0.6, WordPress 2.0.7 is now available for public download. This update addresses a PHP security issue in certain versions of the popular scripting language, as well as a Feedburner problem that was inadvertently introduced in 2.0.6. Similar to the previous updates, the WordPress team labels this as a recommended upgrade.
The short update cycle cites only a small number of files revised for this version:
Because this is a much smaller update than previous versions, you do not have to update all of WordPress’ files if you’re upgrading from version 2.0.6. Here is the list of files that have changed since 2.0.6:
The said zend_hash_del_key_or_index bug that exists in versions earlier than PHP 4.4.3 or PHP 5.1.4 has been addressed in WP 2.0.7, along with the incorrect headers problem that was causing issues with feeds using Feedburner’s service. In addition, a few usability/application behavior changes were made, making this a worthwhile upgrade.
As mentioned, the next major version, WordPress 2.1, will be available by the end of the month though support for the 2.0 series is guaranteed for a few more years.
I’m sure a significant part of the WordPress community is not happy with the timing of this release as most of us has just finished upgrading to 2.0.6. On the other hand, this shows the commitment of the development team to produce a secure product, addressing problems as soon as they could. With a faster release cycle, everyone benefits from the security fixes and feature innovations introduced with each release. Exactly the reason why most of us love open source software.
