This blog is currently running off of WordPress 2.7 and I was impressed at the backup and upgrade features that have been built into it. I would recommend everyone to upgrade to 2.7 and, to entice you, I've listed some of my favorite features below.

Version Control

When you edit a post or page, WordPress will keep a record of every time you save it, and even times in between. That means that you have a full revision history of all of your posts. Liked it better three minutes ago before you completely butchered it? Just open up an old revision a start editing from there.

There's also a view that lets you see the differences between two different versions. Very useful if you're not quite sure what you changed.

Export/Import

WordPress has an Export option, which allows you to export all of your posts, pages, comments, fields, categories and tags into an XML document that you can then import into another WordPress blog. There are also a ton of Import options for a variety of other blog platforms to WordPress. This has been in WordPress for a while and doesn't replace a full database backup, but it is a nice quick way to backup your data.

Auto Update

2.7 now let's you update your WordPress blog with the push of a button, instead of jumping through hoops to upload the files to your site (and maybe accidentally overwrite your themes folder). With the one push update, it'll be easier than ever to keep your site updated with the latest security fixes released by WordPress. I used to do this with Automattic's Subversion repositories, but now anyone can do an upgrade easily without resorting to FTP or crazy command line tricks.

I have had no problems at all with themes or plugins. Everything seems very backwards compatible.

All of these features and the updated Dashboard make WordPress 2.7 a recommended update.

If you've been using WPA encryption for your wireless connection, it may soon be time to move to WPA2. It seems the key exchange process for WPA, called TKIP, is cracked, which will allow people to access your wireless network. This could pave the way for leakage of the data going over these networks too, although that encryption has not necessarily been broken as of yet. Moving to WPA2 should be simple since most routers and devices now support it. And no one should be using WEP.

This might not be such a big thing for home network, although you never can tell what your neighbors are doing with your data. I'm of the better safe than sorry crowd myself, so I switched to WPA2 with AES encryption today. I haven't had any problems connecting my devices.
