Behavioral changes

  • Changed to send Pong before updating the message sender to the routing table when Ping is received. [#566]
  • Improved performance of StoreExtension.LookupStateReference<T>() method. [#447, #545]
  • Added .NET Core 2.2 as a targeted framework. [#209, #561]
  • TurnClient.AcceptRelayedStreamAsync() became to ignore disconnected connections. [#469]
  • Swarm<T>.PreloadAsync() became to ignore peers with lower tip. [#592]
  • Swarm<T> became to validate only stale peers. [#568, #593]
  • Swarm<T> became not to check cached peers immediately after removing peers from its routing table. Instead, it checks cached peers periodically. [#608]
  • Marked Address and HashDigest as readonly. [#610]
  • IceServer.CreateTurnClient() became to throw ArgumentException when received invalid url. [#622]
  • Swarm<T> became to update peer table when receiving messages that are not related with Kademlia protocol. [#594, #627]
  • Swarm<T> became not to check least recently used peer every time when new peer is fetched. [#627]
  • IAction became guaranteed that the given IActionContext.PreviousStates.GetState() never throws IncompleteBlockStatesException. Instead, now it may calculate the incomplete states from the beginning if necessary. [#645]
  • IStore.PutBlock<T>() became to do nothing when it takes the Block<T> more than once. [#647]
  • Swarm<T>.PreloadAsync() became to try downloading blocks from all neighbor peers, even if any peer among them is unavailable to send blocks. [#636]

Bug fixes

  • Fixed a bug where Swarm<T> had tried to update a peer infinitely when the peer is evicted from its table. [#566]
  • Fixed a bug where Swarm<T>.AppendBlocksAsync() re-requests blocks that already received when blockchain is empty. [#550, #562]
  • Fixed a bug that Swarm<T> had thrown SocketException with a message Operation on non-blocking socket would block. [#405, #485]
  • Fixed a bug that accessed all blocks from the genesis block when a swap occurred. [#575]
  • Fixed a bug that Swarm<T> had thrown InvalidBlockIndexException during synchronizing with other reorganized peer. [#528, #576]
  • Fixed a bug where Swarm<T> does not render actions in blocks which are filled from other peers. [#579]
  • Fixed a bug where Swarm<T> renders actions in same block multiple times when reorg happens. [#579]
  • LiteDBStore became to guarantee atomicity of storing blocks. [#584]
  • Fixed a bug that BlockChain<T> had appended a block even if fails to evaluate. [#591]
  • Fixed a bug where Swarm<T> hadn't removed stale peers. [#568, #593, #602]
  • Fixed a bug that TurnClient had thrown IOException when accepting connection through a TURN relay server. [#453, #599]
  • Fixed a bug that KeyNotFoundException occurred when sending a message through the TurnClient.

  • Fixed a bug that BlockChain<T> had reset when Swarm<T>.PreloadAsync() fails. [#644]
  • Fixed bug that whole processes could halt when received an invalid type of message. [#628, #641]
  • Fixed a bug that received blocks could not be processed if a branch point is a stale block. [#655]
