Second Preview Build for the 26.70 Track
Mojang shipped Minecraft Preview 26.70.21 on October 20, 2026, marking the second public test release in the Bedrock Edition 26.70 development cycle. The build is distributed through the standalone Minecraft Preview app — separate from the main game — so players can test work-in-progress features without affecting their stable worlds.
Platforms and Access
The preview is available on:
- Windows (Microsoft Store)
- iOS and iPadOS (via TestFlight)
- Xbox Series X|S and Xbox One
- PlayStation 4 and PlayStation 5
- ChromeOS
- Android (labeled as "Beta" on that platform)
IOS users need to join the TestFlight program through the official Minecraft TestFlight link. Android players receive the build through the Google Play beta track.
What's Actually New
The official announcement page does not list specific feature changes, bug fixes, or experimental toggles for 26.70.21. That omission is not unusual for mid-cycle preview drops; Mojang often reserves detailed changelogs for the feedback site or the wiki community to collate. Players who install the build should check the in-game changelog screen or the Minecraft Feedback portal for the granular breakdown.
Feedback and Bug Reporting
Mojang directs testers to two channels:
- Feature feedback and general impressions: aka.ms/mc-gamedrop_winter26
- Crash reports, world corruption, and reproducible bugs: bugs.mojang.com
Both links are monitored by the development team and factor into whether changes move forward, get revised, or are pulled before the stable 26.70 release.
What Remains Unclear
Without a published changelog, it's unknown whether 26.70.21 introduces new experimental features, iterates on ones from the first 26.70 preview (26.60.29), or focuses purely on stability. The community wiki and feedback site typically fill that gap within 24–48 hours of release. Until then, treat the build as unstable — back up valuable worlds before loading them in Preview.
Context: The Preview Program
Minecraft Preview replaced the older beta distribution model in 2022. It runs as a distinct application, receives updates independently of the retail version, and allows Mojang to push builds more frequently across all Bedrock platforms simultaneously. The 26.70 series is expected to culminate in a stable release later this year, likely tied to the winter game drop referenced in the feedback URL.
