WIP: Release 0.11.0

[mersinvald]

Version 0.11

What's new?

Network support

As of Version 0.11 SputnikVM passes every test in the ETH test suit up to Constantinople hard-fork,
which essentially means that it can be used with the ETH network.

Related Pull Requests:

• add CALLCODE in CALL branch of gas calculation match expression ETCDEVTeam/sputnikvm#337
• Byzantium patches ETCDEVTeam/sputnikvm#349
• SHL, SHR, SAR, and related tests ETCDEVTeam/sputnikvm#352
• CREATE2 opcode ETCDEVTeam/sputnikvm#360
• Sstore gas metering adjustment ETCDEVTeam/sputnikvm#364
• Add CREATE2 patch entry etclabscore/evm-rs#2
• Multi-geth integration bugfixes #22

Changes:

• Byzantium opcodes implementation is tested and refined
• The following opcodes are implemented and tested:
  • SHL, SHR, SAR (EIP-145)
  • CREATE2 (EIP-1014)
  • EXTCODEHASH (EIP-1052)
• SSTORE opcode gas metering adjustments (EIP-1283)
• Number of new and pre-0.11 interpreter bugs fixed

API

SputnikVM API is now more agile then ever: the new DynamicPatch API enables the patch-based configuration
to be performed at runtime, as opposed to static patches that were based on using the static generic types.
This change is particularly useful for multi-chain clients like multi-geth that cooperates with SputnikVM over
an FFI boundary. Now it may configure SputnikVM feature-wise in runtime, and not rely on a pre-defined set of network and fork specific constructors.
All that with keeping overhead as low as possible and completely zero-copy!

Therefore, we recommend switching to evm-network crate as a foundation for Patch-building,
evm-network-* crates are considered deprecated and may not be supported in the future releases.

Related Pull Requests:

• Dynamic patches API etclabscore/evm-rs#23
• Zero copy patches etclabscore/evm-rs#31
• feat(network): add deprecation notice to static-patch crates #36
• feat(docs): improve DynamicPatch and evm-network docs #37

Changes:

• New evm-network with a set of precompiled contracts and re-exports of Patch and DynamicPatch APIs.
• Breaking changes in the Patch trait and related code

Testing

Testing framework for the JsonTests (VMTests from ETH Test Suite) have been majorly reworked,
now it generates a separate native Rust test for each testcase in the Json files, for debugging and subset runs convenience.

Related Pull Requests:

• VMTests rework ETCDEVTeam/sputnikvm#335

Changes:

• use of custom derive macro to generate tests from json files.
• generate benchmarks using criterion.
• update the tests from foundation upstream.
