Aptos sends private v1.49.2 hotfix candidate to testnet validators

Aptos Labs has released a private v1.49.2 hotfix release candidate for its testnet, asking validators to upgrade and recommending the update for fullnode operators. The release notes are limited and do not explain the underlying issue. Aptos says the source code is not publicly available and directs operators to use the provided binaries or Docker image instead. Because the patch is private, the public notice offers little technical detail. The company has published a commit identifier, but it has not disclosed what the hotfix changes internally. The update is intended for testnet, where teams can check network behavior before any similar change is considered for mainnet. The notice does not mention any userfacing wallet, token, or transaction changes.
