What is your favorite new feature in WordPress 2.9?

Well, it turns out these people were correct, as this morning I found a friendly message in my dashboard telling me that WordPress 2.8.4 was ready for me to upgrade!  This was especially good news for me, as for some reason people believe that because I run a WordPress fan blog, that they should try it out on this website. 

Here is what the WordPress team had to say about the WordPress 2.8.3 security update:

Unfortunately, I missed some places when fixing the privilege escalation issues for 2.8.1.  Luckily, the entire WordPress community has our backs.  Several folks in the community dug deeper and discovered areas that were overlooked.  With their help, the remaining issues are fixed in 2.8.3.  Since this is a security release, upgrading is highly recommended.  Download 2.8.3, or upgrade automatically from your admin.

The ribbon reminder in your dashboard just showed up, so you can now do your automatic upgrade, or manually download WordPress 2.8.3 from here.

Due to this being a security update, it is strongly recommended that you upgrade your WordPress 2.8 installations as soon as possible.  This can quickly and easily be done via your WordPress administrator panel (for WordPress 2.7 and newer installations) via Tools –> Upgrade, or you can manually download it here. 

If you’d like to read the official announcement, you can see it here.

Unfortunately, with each new WordPress branch comes changes which sometimes break WordPress plugins, create problems with the WordPress theme you are using, and usually includes changes to the code.   If you upgrade before the themes or plugins you rely on have been updated, this can cause problems.   The iThemes team recently touched on this subject with their post, When Should I Upgrade WordPress?  Their post also includes five helpful things that need done BEFORE you do your one-click upgrade:

1. Make a backup of all your site data
2. Upgrade of all your plugins
3. Visit plugin and theme author websites
4. Disable all plugins
5. Ask yourself if you need to upgrade now

I also recommend waiting a week or so to view feedback before upgrading.

I know several of you haven’t upgraded WordPress to 2.8 yet.   How long do you plan on waiting until you upgrade your WordPress installation?  Please include which version of WordPress you are currently using with your comment!

The changes from WordPress 2.7 aren’t as noticable as they were from 2.6 to 2.7, but it is always worth upgrading to the latest installation in my opinion.   As far as what is new, here is what the WordPress team had to say about the improvements in WordPress 2.8:

Major New Improvements

First and foremost, 2.8 is way faster to use. We’ve changed the way WordPress does style and scripting.

The core and plugin updaters in previous versions of WordPress have been such a success we decided to bring the same to themes. You can now browse the entire theme directory and install a theme with one click from the comfort of your WordPress dashboard.

If you make edits or tweaks to themes or plugins from your dashboard, you’ll appreciate the new CodePress editor which gives syntax highlighting to the previously-plain editor. Also there is now contextual documentation for the functions in the file you’re editing linked right below the editor.

If you were ever frustrated with widgets before, this release should be your savior. We’ve completely redesigned the widgets interface (which we didn’t have time to in 2.7) to allow you to do things like edit widgets on the fly, have multiple copies of the same widget, drag and drop widgets between sidebars, and save inactive widgets so you don’t lose all their settings. Developers now have access to a much cleaner and robust API for creating widgets as well.

Finally you should explore the new Screen Options on every page. It’s the tab in the top right. Now, for example, if you have a wide monitor you could set up your dashboard to have four columns of widgets instead of the two it has by default. On other pages you can change how many items show per page.

You can view the entire list of changes here.
