v0.7.0

Added

• Request a block using the Client
• Add broadcast_random convenience method on Client
• Request a Range of block headers from Client

Changed

• Separate logs from events into different event channels
  • The Log channel is bounded in size and contains informational, but non-critical information
  • The Event channel is unbounded and contains data that must be handled, like IndexedBlock
• Switch to corepc-node instead of unmaintained bitcoincore-rpc
• Load block headers with RangeBounds

Fixes

• Remove unnecessary unwrap when managing filter headers
• Clamp connections to a defined range

v0.6.0

v0.6.0

Added

• Pass FeeFilter to client
• Add Signet and Bitcoin checkpoints

Changed

• Use into_payload in bitcoin 0.32.5

Fixes

• Add check to bits before adjustment
• Remove explicit serde feature
• Use BLOB type for peer service flags

v0.5.0

Added

• Client may fetch a Header at a particular height
• Support for Testnet4 with new example

Changed

• HeaderStore has additional header_at method
• Removed unused IndexedTransaction variant on NodeMessage
• New Progress variant on NodeMessage

Fixes

• Use inline docs for rustdoc
• Check the CompactTarget of the block headers received with far stricter requirements with respect to the difficulty adjustment
• Bump bip324 to 0.5.0 and bitcoin to 0.32.4

v0.4.0

Added

• New HeaderCheckpoint constructor from height
• shutdown, add_scripts, broadcast_transaction methods have blocking APIs
• Add a TrustedPeer while the node is running
• Add change the peer timeout while the node is running

Changed

• Use impl Into whenever possible on NodeBuilder and Client APIs
• Remove the misleading wait_for_broadcast method on Client

Fixes

• Remove Option from Whitelist as it is already a Vec
• Limit the amount of ADDR messages a single peer can send

Full Changelog: v0.3.0...v0.4.0

v0.3.0

• Type alias for Node in builder with default generics

Changed

• HeaderStore and PeerStore traits now have an associated error type
• Node is now generic over H: HeaderStore and P: PeerStore
• Move NodeError subvariants into core

Full Changelog: v0.2.0...v0.3.0

v0.2.0

Added

• just and justfile for local development
• Additional SQL tests with tempfile
• Additional context to database read and write errors
• Support for a new silent payments feature-flag:
  • Receive block filters directly
  • Request blocks directly
  • Pause the node state before downloading filters

Changed

• Disconnect peers if no block is found after 30 minutes
• Find new peers after 3 hour connections
• Node::run is an immutable method
• Check block merkle root
• Download blocks in parallel with filters
• Single ScriptBuf may be added at a time
• Client and ClientSender share methods

Fixes

• Only request headers for inv the node does not have
• Max v2 handshake buffer size increased
• Changes to BlockQueue to not spam peers with requests
• Internal module renames

Full Changelog: v0.1.0...v0.2.0

v0.1.0

What's Changed

• NodeBuilder offers configuration options to build a compact block filters Node and Client
• Client is further split into ClientSender and Receiver<NodeMessage>
• ClientSender may: add scripts, broadcast transactions, rescan block filters, stop the node
• Node may run and send NodeMessage, Warning while running
• Connections to peers are encrypted if ServiceFlags::P2P_V2 is signaled
• Connections are terminated if peers do not respond within a custom Duration
• Peers are selected at random with a target preference of 50% new and 50% tried
• Connections are terminated after long duration times to find new reliable peers
• Blocks are considered "stale" if there has not been a new inv message after 30 minutes. Block headers are requested again to ensure no inv were missed.
• Transactions are broadcast according to a configurable policy, either to all connections for higher reliability, or to a random peer for better privacy
• Default implementers of PeerStore and HeaderStore are SqlitePeerDb and SqliteHeaderDb
• Nodes will no peers will bootstrap with DNS
• Experimental support for connections routed over Tor
