=== Simple Summary === 
  : //Add an option to JSON-RPC filter options (used by ''eth_newFilter'' and ''eth_getLogs'') that allows specifying the block hash that should be included in the results. This option would be an alternative to ''fromBlock''/''toBlock'' options.//

=== Abstract === 
  : //This addition would allow clients to fetch logs for specific blocks, whether those blocks were in the current main chain or not. This resolves some issues that make it difficult/expensive to author robust clients due to the nature of chain reorgs, unreliable network connections and the result set not containing enough details in the empty case.//
