Patch Changes

• [@solana/addresses, @solana/codecs-core, @solana/offchain-messages, @solana/react, @solana/transactions] #1040 32b13a8 Thanks @OrmEmbaar! - Add a function called bytesEqual to codecs-core that you can use to compare two byte arrays for equality.

• [@solana/codecs-strings, @solana/kit] #999 d7f5a0c Thanks @tmm! - Some npm packages are needed for specific runtimes only (eg. React Native, Node). To prevent package managers from unconditionally installing these packages when they have auto-install-peers enabled, we are marking them as optional in peerDependenciesMeta. When running in React Native, be sure to explicitly install fastestsmallesttextencoderdecoder. When running in Node, be sure to explicitly install ws. When using @solana/react, we will presume that you have already installed react.

• [@solana/rpc] #1028 eb49ed7 Thanks @mcintyre94! - Add a type SolanaRpcApiFromClusterUrl

• [@solana/rpc-api] #978 c97df88 Thanks @nonergodic! - Expanded the type of several RPC inputs to accept readonly arrays of values

• [@solana/transaction-confirmation] #1003 18e7e2c Thanks @damianac! - Actually fixed a bug where transaction errors discovered during recent transaction confirmation might not be thrown. The fix in #793 was insufficient.

• [@solana/transaction-messages] #1026 81a0eec Thanks @mcintyre94! - Export BlockhashLifetimeConstraint and NonceLifetimeConstraint

• [@solana/transactions] #1058 2f7bda8 Thanks @mcintyre94! - Remove TransactionWithLifetime from required input type for signTransaction and partiallySignTransaction
