  • Unit tests for gossip message processing: Add some unit tests for channel related gossip message processing fiber#418
  • Simplified and cleaned up code for better readability: chore: simplify fn prune_messages_to_be_saved fiber#414 chore: code cleanup fiber#417
  • TLC ACK operation revisited: Tlc operations wait dual ack fiber#416
  • Retryable forwarding TLC introduced: Add retryable forwarding tlc  fiber#440
  • Ongoing extensive tests to ensure Fiber’s stability
• ckb-script-templates
  • Better instructions and error messages introduced for native simulator: Add instructions and error messages about generate-native-simulator cryptape/ckb-script-templates#21
  • Compatible templates ensured with the latest cargo-generate: Ensure destination folder exists before invoking cargo generate cryptape/ckb-script-templates#25
  • Better handling of different packaging strategies amongst different distribution: Leverage another LLVM binary to locate current clang binary cryptape/ckb-script-templates#23
• ckb-js-vm
  • Updated upstream dependencies: Update upstream and refactor project structure ckb-js-vm#21
  • Introduced fs.lua to JavaScript: feat: rewrite fs.lua in JavaScript(node) ckb-js-vm#22

Fixes

• Fiber
  • Fixed missing broadcast messages during a query request: Query missing broadcast messages from peers fiber#428
  • Cached ChannelAnnoucement timestamp to reduce round-trips with CKB: Save our own broadcast message directly and save raw gossip message from peers to memory first fiber#434
  • Made CI more resilient with configurable syncer count: Make number of active/passive syncers configurable fiber#429
  • Fixed CI failure by propagating panics: Panick the whole program when actor panick fiber#435
  • Adopted Molecule for deterministic hashing: fix: deterministically hash should use molecule fiber#415
  • Adopted Molecule for serializing relevant data structures: Use molecule for hopdata and tlc_err fiber#425
  • Adjusted gossip to ignore private addresses: fix: gossip actor and graph should ignore private address fiber#421
  • Allowed private channels as sources: fix: use private channel as source should be ok fiber#426
  • Properly set inbound channel actor names: fix: inbound channel actor name fiber#439
  • Regulated field names in RPC: [BREAKING CHANGE] fix: unify the fields name in rpc fiber#441
  • Cleaned up channel RPC and fixed self payment when both parties have 0 remote balance: Add custom hop hints and fix self payment fiber#432
  • Resolved a self payment error: fix a bug in direct channel fiber#411
  • Ensured the network graph updated properly when a message is received: Retry all payment session with actor message fiber#430
  • Updated network graph when a channel is closed: Network graph should sync up when channel closed fiber#412

In Pipeline…

• Fiber 1.0.0 release is in progress. Please stay tuned!
• Cryptape’s website is undergoing a major overhaul.
