     - `getMintInterface` (decompressed light-mint branch) now validates the on-chain mint owner and throws `TokenInvalidAccountOwnerError` on mismatch; it also forwards the provided `commitment` to on-chain `getAccountInfo`.
     - **Migration impact:** callers that previously interpreted these paths as empty/not-found must now handle thrown errors explicitly (retry/backoff or surfacing RPC health).

 - **`decompressInterface` removed.** Use `loadAta` (action) or `createLoadAtaInstructions` (instruction builder) instead. `decompressInterface` did not support >8 compressed inputs and has been fully removed.
     - **Action (send transaction):** Replace `decompressInterface(rpc, payer, owner, mint, amount?, destinationAta?, destinationOwner?, splInterfaceInfo?, confirmOptions?)` with `loadAta(rpc, ata, owner, mint, payer?, confirmOptions?, interfaceOptions?, wrap?)`. Derive the target ATA with `getAssociatedTokenAddressInterface(mint, owner)` for light-token, or pass the SPL/T22 ATA to decompress to that program. `loadAta` loads all cold balance into the given ATA (no partial amount); it supports >8 inputs via batched transactions and creates the ATA if needed.
     - **Instruction-level:** Use `createLoadAtaInstructions(rpc, ata, owner, mint, payer?, interfaceOptions?, wrap?)` to get `TransactionInstruction[][]` and send batches yourself. The single-instruction primitive is no longer exported; use the batched API only.

 # Changelog
 
+## [0.23.0-beta.10]
+
+### Breaking Changes
+
+- Default build target is now V2 when `LIGHT_PROTOCOL_VERSION` is unset. This applies to bundle replacement (`__BUILD_VERSION__`) and package scripts (`pnpm build`, `pnpm build-ci`). To force V1 builds, set `LIGHT_PROTOCOL_VERSION=V1`.
+
+### Changed
+
+- Beta-gated interface RPC paths remain enabled by default in V2, and `getAccountInfoInterface` now propagates upstream RPC errors whenever no definitive account result is available (instead of silently returning `null` on fetch failure paths).
+
 ## [0.22.0] - 2025-06-16
