v0.1.0

Release notes

This release marks the first initial version of stackup-bundler with a major version 0 that can be used in testnet.

v0.1.0 is not recommended for mainnet use.

EntryPoint support

This version supports the EntryPoint deployed at eth-infinitism/account-abstraction@57c5d77c77.

• EntryPoint address: 0x78d4f01f56b982a3B03C4E127A5D3aFa8EBee686

Future breaking changes

For v0, each breaking change will result in a minor version bump. A patch update will be reserved for non-breaking changes that are backwards compatible. An example of a breaking change might include new EntryPoint deployments and updates to the bundler interface.

Since each EntryPoint is a seperate singleton contract, you may still use older versions without any issues.
