I have upgraded all the websites and blogs from WordPress 2.9.1 to WordPress 2.9.2. The same blogs and sites that I upgraded to WordPress 2.9 and WordPress 2.9.1 from WordPress 2.8.6.
I upgraded the sites and blogs using the WordPress Automatic Upgrade feature and did not encounter any problems at all. The Image Gallery Problem has also been fixed the last time I upgraded the sites and blogs to WordPress 2.9 and WordPress 2.9.1.
Upgrading to WordPress 2.9.2 was not really necessary when it comes to the websites and blogs that I maintain but I opted to upgrade them anyway.
WordPress 2.9.2 was a fix release to a problem where logged in users can peek at trashed posts belonging to other authors. If you have other users registered on your blog and you do not like your posts being looked at despite being in the trash, upgrade your site or blog to WordPress 2.9.2.
You can download the new fix release of WordPress from the Download section or from the Release Archive section of WordPress.org.
Remember, before upgrading anything, back up your files and databases first. You can back up your files via FTP or File Transfer Protocol. You can back up your database via phpMyAdmin. Read my previous blog entry on how to back up database via phpMyAdmin.
