Finally, the API we’ve all be waiting for!
Well, I’ve not been waiting for it, since I made it, and you may not have been waiting for it if you don’t plan on making an add-on… but I’m sure many people have been waiting for it simply to see what other people are going to make! :P
The API is still in alpha; only minor changes with this release. Be sure to give me feedback on the Mystcraft Forums!

This release is primarily to handle the changes in structure gen in Minecraft 1.6.4. Otherwise, this update saw some bug fixes and general balance tweaks. Be sure to check out the changelog.

Keep in mind that you need link panels to make books! This is for both descriptive and linking books.

To recap: there is only one download (found at the bottom of this post); This file is the universal install for client and server; it no longer goes in the jar.
Mystcraft goes in the mods folder.

If you are still lost on the 0.10 series, check out Direwolf20′s Mod Spotlight! Direwolf20′s Mod Spotlight for 0.10.4.00
If you are having trouble with writing, check out Direwolf20′s Writing tutorial!
Note that there are a couple changes between the video and the current mod, particularly that colors and things are easier to write. If you follow the tutorial, you’ll do great.
