- ID 14: Block State (non-optional, explicit; confirmed new in 1.19.4). ViaVersion `EntityDataTypes1_9` through `EntityDataTypes1_19_3` have only `optionalBlockStateType` (never a separate `blockStateType`); `EntityDataTypes1_19_4.java:45` is the first to add `blockStateType = add(14, Types.VAR_INT)` alongside `optionalBlockStateType = add(15, Types.VAR_INT)`.

- `<!-- UNCONFIRMED -->` — Whether `Block State` (ID 14, non-optional) already existed in 1.14–1.19.2 or was truly new in 1.19.4: ViaVersion's 1.14 class omits it (only `optionalBlockState` at 13) but 1.19.4 explicitly has both 14 and 15. This implies the split was at 1.19.4, but no direct minecraft-data diff or wiki changelog entry in the available sources explicitly names this change.
- The `optional_global_pos` value in 1.21.1 (`minecraft-data` encodes it as `['option', 'string']`) — the string appears to be the dimension name key only, not a full ResourceLocation + Position pair as ViaVersion's `OPTIONAL_GLOBAL_POSITION` type implies. <!-- UNCONFIRMED: need to cross-check against the Minecraft wiki Optional Global Position definition. -->
- **Block State (ID 14, non-optional) first appeared in 1.19.4**: confirmed — ViaVersion's 1.14, 1.19, and 1.19.3 classes have only `optionalBlockStateType`; 1.19.4 adds both `blockStateType` (14) and `optionalBlockStateType` (15). See §4.6.
- **`optional_global_pos` wire encoding**: confirmed — `GlobalBlockPositionType.java` reads `String dimension` (the dimension ResourceLocation, e.g. `minecraft:overworld`) + `BLOCK_POSITION1_14` (packed i64 position). The `minecraft-data` `['option', 'string']` representation is a schema approximation; the actual wire format is `bool` + (if present) String + packed Position. Source: `ViaVersion/.../api/type/types/math/GlobalBlockPositionType.java:41-43`.
- Pose enum values beyond the 1.14 original (e.g. `Croaking`, `UsingTongue`, `Roaring`, `Sniffing`, `Emerging`, `Digging` added for 1.17–1.20 mobs) — not enumerated here; the authoritative list is at `minecraft.wiki/w/Entity_format#Pose`.
