According to @deanmlittle, Mollusk has now updated its RentExempt check to return true for accounts with 0 lamports that belong to the System Program, aligning with Solana mainnet behavior. This technical change increases compatibility for developers and may reduce unexpected errors during program deployment or testing on Solana. This update is particularly relevant for traders and developers monitoring Solana (SOL) network upgrades and ecosystem reliability. Source: @deanmlittle via Twitter.
