1.1.3 (26.3)

Fixed lightning not being targetable with @e
Fixed some nbt paths in data commands not updating nbt correctly

1.1.2

• Fix crash when setting active_effects on an entity
• Fixed block access not working when "fix block access forceload" is turned off
• Fixed list indexing not working for top-level nbt data (ie. Inventory[0])

1.1.1 (26.3)

Added fabric api as dependency to mod json

1.1.0 (26.3)

Updated to 26.3
Removed entity name optimizations. Mojang has added this optimization to vanilla.

1.0.2 (26.2)

Fix execute store not working in some cases

1.0.1 (26.2)

Fix data modify not working in some cases

1.0.0 (26.2)

Radon is now Bellows!
Because someone beat me to the name years ago and I'm only just now changing it.

This version introduces some new optimizations including:

• execute as/on no longer re-computes the entity display name, and instead only computes it when needed
• "Quick Data" special hard-coded cases that bypass nbt serialization entirely and update entities directly (currently only used for transformations)
• Optimizations to "transformation" and "data" nbt fields
• Compatibility with Moonrise

Additionally, Bellows (ngl feels weird to type that) now has tests, which it will make it far less likely that bad nbt pathing makes it to production (it doesn't cover every case but I'll work on that).

0.10.16: Smithed Summit 2026 Edition

This is a special version of Radon used for Smithed Summit 2026, made available for anyone trying to run the map in single player. This version includes some changes that will not be released in mainline Radon, including some new commands we needed that I hacked in.

0.10.2 (26.2)

Improved situations where multiple NBT fields needed to be bundled together (adds some cases to optimizations, fixes some cases where deserialization would happen twice).
Fixed display entity transformation interpolation.

0.10.1 (26.2)

• Fixed some nbt not being modifiable on some entities
• Fixed 'start_interpolation' field causing worse performance
