Scheduled
We are upgrading our Sui Testnet infrastructure to testnet-v1.79.0. This release introduces protocol version 136. During the maintenance window, brief interruptions to RPC availability may occur.
## RPC Changes
**`simulateTransaction` — modified** Transaction expiration responses now return VALIDITY instead of VALID_DURING. Clients that reconstruct the expiration from the response must include the new allowed_proposers field to ensure transaction digest matching; clients that use the response unchanged are unaffected.
**`PTB TxContext` — modified** TxContext restrictions are now enforced at the protocol level. TxContext may appear at most once as &mut TxContext or any number of times as &TxContext in a PTB Move call signature, and never by value or in return position. Transactions violating these rules now fail immediately with InvalidTxContext error.
