Due to flaws the previous changes to the configuration system combined with some bad lines in the experience.config that I mistakenly recommended, herbalism was not granting experience in most cases, as it was marking newly planted crops and such as player placed no exp granting blocks, rather than ignoring them as it should.
block types now are evaluated in 3 steps:
1: Explicit Name i.e. ("Crops|4", "Crops|0"), Which is the material name then data value
2: "friendly name" i.e. ("Crops_Ripe", "Crops_Ungrown"), Which is a typically data valueless name, some of which I make up in mcMMO, but most of which are just the Material name
3: Wildcard name i.e. ("Crops|*") Which is any block with that block value, regardless of data value
In order to be sure herbalism grants exp for you once again, make sure your configuration for herbalism looks similar to this:
https://github.com/mcMMO-Dev/mcMMO/blob/master/src/main/resources/experience.yml#L151
In terms of which blocks are listed there. Specifically, there should be no blocks marked "ungrown"
The child permission has the value set to false. From http://bukkit.gamepedia.com/Plugin_YAML: "a child node of false inherits the inverse parent permission". Having the value set to false grants the permission to reset other players' skills to everyone that doesn't have the mcmmo.skillreset permission, which by default nobody has.
This fixes brewing on the newest Spigot API builds. The Alchemy skill was completely broken due to a change in the Spigot BrewEvent constructor, which this fixes via the changes to FakeBrewEvent.java and AlchemyPotionBrewer.java. This also adds a check in EntityListener.java for armor stands, so that health bars aren't displayed for them. The health bars never really displayed properly (armor stand health acts differently from most entities), and it allowed players to punch invisible armor stands server admins may have been intentionally hiding to temporarily reveal them via a health bar, which is an issue.
