Below you will find all of the different pack.mcmeta files with the newest on top. This list is up to date for the latest release. I don't include downloads for beta or preview files as these change too much before release.
The basic format stays the same but you might see the coding all on one line or separated out by lines, which is what I do because it makes it easier to edit.
