Breaking changes

Protocol buffers for hardware wallet transactions are no longer supported. Internet Computer Ledger app 2.4.9 or later is now required.
GovernanceCanister.listNeurons no longer throws an error when called with certified: false for hardware wallet transactions.
Potential errors thrown by withdrawEth provide now unparsed details.

ICP transactions, as provided by the Index canister, have been extended to include their block timestamp information.
When no fee is specified when making an ICP transaction, use the mandatory fee of 10000 e8s (0.0001 ICP) instead of fetching the fee from the network.
Remove hardware wallet specific code paths from @dfinity/ledger-icp.
Remove hardware wallet specific options from LedgerCanister.
Remove dependency on @dfinity/nns-proto from @dfinity/ledger-icp.
Remove hardware wallet specific code and @dfinity/nns-proto dependency from @dfinity/nns.
Add support for withdrawErc20.
Additional fields related to ERC20 have been added to ckETH minterInfo.
Expose the function ledger_id for Index canister in the ledger-icrc library.
Set number of retries to 10 (as opposed to default 3) in createAgent utility to make the agent more resilient against watermark check failures.

Upgrade agent-js dependencies to v1.2.1. Note that it is advised to set the number of retries of the agent to 10 to prevent the potential issue Timestamp failed to pass the watermark after retrying the configured 3 times. We cannot guarantee the integrity of the response since it could be a replay attack. (see thread on the forum).
Upgrade didc to 0.3.7 that converts candid files into JS and TS.
