    • Update uninstallFilter and getFilterChanges accordingly
    • uninstallFilter stops the polling goroutine
    • getFilterChanges returns the filter's internal list of block hashes and resets it
  • (rpc) tharsis#54, tharsis#55 Implement eth_getFilterLogs and eth_getLogs:
    • For a given filter, look through each block for transactions. If there are transactions in the block, get the logs from it, and filter using the filterLogs method
    • eth_getLogs and eth_getFilterChanges for log filters use the same underlying method as eth_getFilterLogs
    • update HandleMsgEthereumTx to store logs using the ethereum hash
  • (app) tharsis#187 Add support for simulations.

Bug Fixes

  • (evm) tharsis#767 Fix error of timeout when using Truffle to deploy contract.
  • (evm) tharsis#751 Fix misused method to calculate block hash in evm related function.
  • (evm) tharsis#721 Fix mismatch block hash in rpc response when use eth.getBlock.
  • (evm) tharsis#730 Fix 'EIP2028' not open when Istanbul version has been enabled.
  • (app) tharsis#749 Fix panic in AnteHandler when gas price larger than 100000
  • (rpc) tharsis#305 Update eth_getTransactionCount to check for account existence before getting sequence and return 0 as the nonce if it doesn't exist.
  • (evm) tharsis#319 Fix SetBlockHash that was setting the incorrect height during BeginBlock.
  • (evm) tharsis#176 Updated Web3 transaction hash from using RLP hash. Now all transaction hashes exposed are amino hashes:
    • Removes Hash() (RLP) function from MsgEthereumTx to avoid confusion or misuse in future.
