Just as I have been doing for the last several versions I will be updating to run the most recent version of the WordPress beta (version 3.3-beta1 as of this writing) live on this site as well as all of the other domains I own where WordPress is installed.
Although I have complete confidence in the stability of the beta versions I would still only suggest / recommend this practice to those with a reasonable knowledge of PHP and the ability to recover from any potential catastrophic disaster (read: BACK-UP everything first!!!).
Here are the basics, as each version changes these may not be exactly the same but should still serve as a general guideline:
- Back up your WordPress installation (all of it).
- Using your preferred text editor, open the /wp-includes/version.php file in core to edit.
- Find and change $wp_version to a ‘point value’ greater than the current version, for example: 3.4-alpha.
- Go to your the Administration Panels (“Dashboard”) of your WordPress installation.
- Scroll to the bottom of the page and click on the “stay updated” link in the bottom-right corner. (Refresh the page if the link is not there.)
- Follow any additional prompts, such as updating the database, etc.
You should now be running the latest version of ‘trunk’.
