Arbitrum developers have released a new version of the SDK with several updates and features for EthBridger, Erc20Bridger, L1TransactionReceipt, L1ToL2MessageCreator, InboxTools, and Networks.

• EthBridger includes updates with a new static method for creating an instance with a provider called "createInstanceWithProvider." Additionally, a method has been added for depositing funds via a repeatable ticket, with the option to choose the target address
• Erc20Bridger also has a new static method for creating an instance with a provider
• L1TransactionReceipt has two new functions. The first is for reading classic layer-1-to-layer-2 messages, and the second method is for checking whether a transaction was made on Classic or Nitro. Additionally, "getL1ToL2Messages" has been updated to display an error when attempting to read classic messages
• L1ToL2MessageCreator has an updated "createRetryableTicket" method, which was not previously behaving correctly
• InboxTools has two new functions: one for creating a signed layer-2 transaction and the other for sending a signed layer-2 transaction to the Inbox
• Networks has a new function that specifies the first Nitro layer-1 block. Additionally, links to block explorers for Arbitrum Goerli and Arbitrum Nova have been updated, and Rinkeby and Arbitrum Rinkeby have been removed from the list of supported networks

Several documentation fixes have also been made, as well as internal changes to CI and testing.
