I’m new to Selenium and I’m a bit confused about the version numbers. Selenium 2.0 was released in 2011. I just downloaded the Selenium IDE Firefox extension and it is version 1.7.2. Is there also a 2.0 release of the IDE, or does the 1. x series confusingly contain the 2.0 code?
I checked Selenium HQ, which states that 1.7.2 is currently the latest release of the Selenium IDE.
Versioning of Selenium releases has always been kind of confusing. The essential difference between Selenium 1 and 2 is that Selenium 1 used the Selenium Remote Control interface, while Selenium 2 is based on WebDriver. That means: Selenium 2 tests are such ones that you write in code, e.g. in Java, in an object-oriented manner. Everything you record or script using the Selenium IDE uses the Selenium RC interface, which still works with Selenium 2 for backwards compatibility. So there is no Selenium IDE 2.
