We still plan on a major update in the coming weeks. Due to delays we preferred pushing a minor build before that happens.
As a reminder, short term plans include reviewing, testing and pushing the following changes:

• some balance changes from Bunnie's CTF Rebuild project, such as faster building during build time, more coin gain from combat, faster hitting on player-built blocks, sawjump removal. If you're interested, you can read more here: https://rentry.co/rebuild-prs (not everything may be added)
  
• raycasted slashes (Doors will no longer makes builders immortal at certain angles - this led to the frustation of many knight players)
  
• 360 degree trampoline rotation
