What you need to know

  • We're in the final stretch before the release of Part One of the 'Caves and Cliffs Update' for Minecraft.
  • Mojang Studios is working on final polish with a ton of bug fixing planned in the last few betas and snapshots.
  • Today's Minecraft: Bedrock Edition Beta 1.17.10.21 surprises Minecraft players with a new feature on top of the usual fixes.
  • Potted azalea and potted flowering azalea are being added to Minecraft: Bedrock Edition with today's beta.

Minecraft is a few days away from receiving its next major release with Part One of the Caves and Cliffs Update launching on June 8. Mojang Studios is hard at work ensuring the update is as stable as possible with a flurry of new Minecraft: Bedrock Edition betas and Minecraft: Java Edition snapshots in the lead-up to the Caves and Cliffs Update. Today, Mojang Studios is releasing Minecraft: Bedrock Edition Beta 1.17.10.21 with a new batch of bug fixes. However, today's beta also surprises by adding a new feature to the imminent Caves and Cliffs Update.

With Beta 1.17.10.21, Mojang Studios is added potted azalea and potted flowering azalea to the game. If you fancy the look of these new Lush Cave plants, you can now place them in a flowerpot and decorate your home or base with them. It's rare for features to be added to major updates so close to release, so it's nice to see Mojang Studios add these two new items to the game. On top of that, there's also the usual swath of bug fixes and general improvements to look forward to.
