WordPress 1.5.2 Changes - In Plain English
This list details the changes made from WordPress 1.5.1.3 to 1.5.2. I tried to take the developer-speak out of the descriptions, but some items are inherently code-related. I produced this list by reading the changelog on WordPress’ development system, and reading the changes in the code (not just the descriptions of the tickets that were fixed) for each change.
If you’re more interested in specific details of what was changed than this overview, please look at the Trac changelog, which is the scary hive of code and dev-speak that I have interpreted for you here.
