I’ve been using WordPress for more than five years now and have seen it through all its revisions. For those of you who came online recently, take a look at a picture journey through the several years of WordPress.
Looking at 2.7 released recently, you’ll never realize the rough interface that we used to blog five years ago.
Ozh also implemented a WordPress Functions Implementation History Tool which will let you search across nearly 2500 functions through 45 WordPress releases, i.e. right from 0.7.1 upto the latest 2.7.
This is ofcourse for developers who need to make sure their plugin or theme works well with other versions.
When did you begin to use WordPress? Which versions have you used so far?
