Incompatible Changes

• RPC Changes

  • Refactor the design and implementation of transaction trace. trace RPCs will be affected. Check Conflux-Chain/CIPs#88 for details. (#2286, #2292)

• Configuration Changes

  • Remove default dev mode ports. The users should configure open ports if they want to access RPCs. (#2328)

Improvements

• Implement transaction pool garbage collection based on strict priorities (including transaction readiness, gas price, e.t.c.). (#2287, #2291)
• Sample a subset of transactions with higher gas prices for packing. This reduces the packing time for high-price transactions. (#2312)
• Reject invalid receipient in txpool. (#2289)

Bug fixes

• Fix an issue that may cause the transaction pool to stop garbage collecting and always remains full. (#2357)
• Fix an issue that if the node is serving multiple state-related RPCs concurrently, some states may fail to be opened. (#2293)
• Fix a possible OOM issue during node restarting. (#2267)
• Fix blocked catching up issues of a heavy fork subtree. (#2280)
