How to select mbed OS in online IDE
I'm trying to compile a project using https://os.mbed.com/compiler/ - it was written for an older mbed version with deprecated methods - when I go to compile it looks like it's using mbed 5.7 - how can I select an older version of mbed through the ide such as 5.2, 3, or heaven forbid, 2?

mbed2 is fine, if you don't need an RTOS and multiple threads then it gives you very similar features to the current version 5 but with a far lower overhead. Some boards only support mbed 2 due in part to memory or speed limitations, some newer boards only support mbed 5.
In the online compiler import the library mbed for mbed 2 or mbed-os for mbed 5.
Once the library is imported select it in the left hand tree and click on revision at the top of the window.
After a little bit of thinking you should get a list of all the revisions of the mbed library. To select an older version click on the version you want and click switch.

There's no way for the online compiler to change versions. You can go out to github and fork the version of interest and then import it into your project. This may not be the version you're interested in but you can thumb through github and the version you want from here. https://github.com/ARMmbed/mbed-os/releases?after=mbed-os-5.2.1
Yes there is. What would be the point of having a version control system if you couldn't go back? You can't easily switch between 2 and 5 but there are enough differences between them that you wouldn't normally want to but between different releases of 2 or different releases of 5 is easy.
