v0.10.0

[Nana-EC]

v0.10.0 of the Hedera JSON RPC Relay adds support to a new endpoint eth_maxPriorityFeePerGas as well as improvements to IHederaTokenService precompile contract access, rate limiting, subgraph support and metamask NFT support.

The eth_maxPriorityFeePerGas API endpoint was added to increase our coverage of the RPC API methods expected by tools.

The relay was updated to support direct calls to the IHederaTokenService precompile contract. eth_getCode calls to the IHederaTokenService contract won't fail and in this way developers can make calls to the contract from their dev tools using the contract address without requiring a wrapper contract on ledger to route the call.

Rate limiting logic continues to be improved, in this release a bug was fixed in which some clients were unnecessarily being throttled.

Subgraph support was also expanded and documentation updated to highlight the current extent of support - The Graph Integration. Advancements will continue to be made as they become possible with the Mirror EVM Archive Node.

A metamask issue was also resolved in which NFTs being loaded into Metamask were witnessing a UI stall due to limited Metamask logic. The relay was updating to support additional logic to better report serial details and support Metamask RPC calls.
