v0.6.0-rc.0

Release notes

This release supports the latest ERC-4337 EntryPoint update to align on-chain and off-chain userOpHash.

ERC-4337 contracts @9b5f2e4

This version supports the EntryPoint deployed at eth-infinitism/account-abstraction@9b5f2e4.

• EntryPoint address: 0x5FF137D4b0FDCD49DcA30c7CF57E578a026d2789

Why a release candidate?

At the time of this release, the official bundler compatibility test suite has not yet been updated for the latest EntryPoint. Although v0.6 has been tested against the latest contracts, the rc status will remain until the test suite has been updated.

Where is v0.5?

v0.5 will be skipped so we can align the stackup-bundler version number with the official EntryPoint version to reduce any confusion.
