Hey there ZacharyNP!
Our course was designed for Minecraft 1.7, we're actually looking in to updating the course as we speak, so keep your eyes peeled for that! The course will however work on any version of Windows, don't you fear.
Also, the modding is relatively between different versions of Minecraft, so you can take the lessons you learned modding 1.7 and apply them to 1.8, 1.9, and maybe even 1.10!
I hope this answers all of your questions!
