What changed

1. 1.0.0

   LatestOctober 2, 2026 · Minecraft 1.21.1, 26.2
   • Give and equip actions can add enchantments: pick them, or let Blerp pick random ones.
   • Gameplay toggles (explosive projectiles, pokeball, yeet mobs, one punch, one shot trees) can turn themselves off after a set time, and they stay on when you leave and rejoin a world.
   • Helper commands run in your current dimension, so explosive arrows, pokeball, sniper tower and bee disaster work in the Nether and the End.
   • A Blerp button on the pause menu shows the connection status, the bridge port and switches for the connection light and messages, plus a live log you can copy.
   • Actions that arrive while no world is loaded wait up to a minute and then run, and an action never runs twice.
   • A connection light in the top left shows when Blerp is connected. Turn it and the chat messages on or off with /blerpbridge or under Controls > Blerp.
   • New Show Message action posts a message in chat that only the streamer sees.
   • Long titles and subtitles shrink to fit the screen instead of being cut off.

2. beta-1.2

   BetaAugust 3, 2026 · Minecraft 1.21.1, 26.2
   • Works on Minecraft 1.21.1 again, as well as 26.2.
   • Stricter checks on commands, so actions run more consistently on each Minecraft version.
   • Viewer minions keep following you across chunk loads, long teleports and dimension changes.
   • The bridge picks another port when 9123 is busy, and /blerpbridge shows or changes it.
   • Mobs can spawn at a random size between a smallest and a largest.
   • New action: spawn a baby zombie.

3. beta-1.1

   BetaJuly 19, 2026 · Minecraft 26.2
   • Viewers can summon named minions that follow you, as a Companion or a Guardian.
   • Guardians fight mobs you attack and enemies that hurt you, and minions can be made invincible.
   • Many creatures work as minions (wolves, cats, foxes, allays, bees, parrots, llamas, polar bears, sniffers, armadillos, golems and more), they stay across reloads, and a new action clears them.
   • Actions can reach mobs up to 200 blocks away.
   • Only for Minecraft 26.2.

4. beta-1.0

   BetaJuly 9, 2026 · Minecraft 1.21.1, 26.2
   • First public beta: viewers trigger sounds, effects, items, structures and other moments in your world while you play.
   • In game this version calls itself beta-1.5.
