So we all know when we type /give, we use numeric ID's to identify blocks and items. But if you've tried it in 1.7.2, it has a warning telling you that numeric ID's will be obsolete, and will be replaced by things like minecraft:stone, minecraft:potion, and so on. Sub-id's like 12:3 will not be effected though. But for those who can't memorize the new ID's like how they memorized the old ones, here's a chart of the future ID format.
| Block | Old ID | New ID |
|---|---|---|
| Example | Example | Example |
