Some snapshots are bigger than others, and this is a smaller one. This week's snapshot was pushed out by Nathan Adams and includes fixes for seventeen bugs, multiple snow hights, team-based functionality for redstone scoreboards, and an adjusted balance of bonemeal. The bugs that were fixed include spawn protection not working, furnace minecarts dropping minecarts and TNT, and several bugs related to the new redstone functionality. See the source link below for all the fixes and the download.Source: Mojang
