Infection
If enabled players and horses can be infected after being hit by a zombie, turning into a zombie after 5 minutes have passed or they die with the infection.
In a players case this will kill them and spawn a zombie player in their place.
This infection can be cured with a golden apple with the default settings, but can be configured to be any item which can be consumed, but not reversed.
Optional settings that are enabled by default extends this to villagers, preventing zombie villagers from being cured.
Has an option in the config to add any zombie variants of other mods mobs to the list of entities that can become zombified, providing there is a corresponding zombie for it to convert into.
1.3.0+ now has support for custom textures to make it possible to add zombified variants of similar mobs.

Zombie Players

When a player dies from infection or dies when an optional setting is enabled a zombified version of that player spawns in their place, containing all their items, when underwater a drowned version, or when in hot biomes, a husk version.
By default zombie players are immune to sunlight, but this can be disabled in the config.
Other Misc Tweaks
Optional settings to make zombie horses a hostile mob (enabled by default) and to prevent undead mobs from burning in sunlight (disabled by default).
