As you may have noticed, we now offer three versions of PHP on our web servers. Version 5.2 is really on its way out and is no longer recommended. The most stable version is 5.3, but we did make 5.4 available for those of you who wanted to move ahead with that upgrade. Please note that with the latter, you may be noticing incremental upgrades and patches from time to time. If you have 5.4.x installed on your domain, these upgrades may or may not affect you. If it does affect you, you will have to either remove the affected application or downgrade your php version for that domain in the DreamHost panel to 5.3 (Click Edit for your domain on Manage Domains, and find it in the Fully Hosted settings). That said…
Due to some site incompatibility concerns that arose since the last time we upgraded to the latest PHP version (currently 5.4.2), we are starting a conversation with you, the customer, to gain better insight and to provide a forum for you to contribute your findings, ideas, questions and concerns.
Here we will post all version upgrades (incremental or full), and will be monitoring it. We would like to hear from you: what did you notice, did it affect your site, what exactly was affected, etc. We are hoping this to become not just an information exchange among our customers, but that we can also learn from it to better prepare for our upcoming upgrades. We perform the upgrades to continue protecting the servers your sites are hosted on, but we understand that there is always room for improvement. Thanks for taking part in the discussion!
