The 1.9.x snapshot 16W14A has just been released on April 7, 2016! This snapshot is mostly for fixing bugs, and does not add much. Most people are probably wondering why there are no snapshots for Minecraft 1.10. Although 1.10 is currently being worked on, there won’t be any snapshots for 2-3 weeks, according to Mojang. However, there will be a release for 1.9.3, so be on the lookout!
