BrewBlogger developers began upgrading the program's associated MySQL database starting with v1.3.1. If you have 1.3 and want to upgrade to 2.2.0, you should download and install each of the docs below in sequence. Likewise if you have 1.3.1, start with 1.4 and go on. You get the idea.

• Version 2.3.1
• Version 2.3.0
• Version 2.2.0
• Version 2.1.0
• Version 2.0.2
• Version 2.0.1
• Version 2.0.0
• Version 1.4.0
• Version 1.3.1

• BJCP 2008 Styles (this update is included in the new install version of BrewBlogger 2.2 and 2.3)
