v0.4.0

[0.4.0] - 2023-05-23

This release introduces breaking changes to the litep2p crate, primarily affecting the kad module. Key updates include:

• The GetRecord command now exposes all peer records, not just the latest one.
• A new RecordType has been introduced to clearly distinguish between locally stored records and those discovered from the network.

Significant refactoring has been done to enhance the efficiency and accuracy of the kad module. The updates are as follows:

• The GetRecord command now exposes all peer records.
• The GetRecord command has been updated to handle errors and unexpected states without panicking.

Additionally, we've improved code coverage in the kad module by adding more tests.

• Add release checklist (#115)

v0.3.0

[0.3.0] - 2023-04-05

litep2p v0.2.0

This is the second release of litep2p, v0.2.0. The quality of the first release was so bad that this release is a complete rewrite of the library.

Support is added for the following features:

• Transport protocols:
  • TCP
  • QUIC
  • WebRTC
  • WebSocket
• Protocols:
  • /ipfs/identify/1.0.0
  • /ipfs/ping/1.0.0
  • /ipfs/kad/1.0.0
  • /ipfs/bitswap/1.2.0
  • Request-response protocol
  • Notification protocol
  • Multicast DNS
  • API for creating custom protocols

This time the architecture has been designed to be extensible and integrating new transport and/or user-level protocols should be easier. Additionally, the test coverage is higher both in terms of unit and integration tests. The project also contains conformance tests which test the behavior of litep2p against, rust-libp2p, go-libp2p and Substrate's sc-network. Currently the Substrate conformance tests are not enabled by default as they require unpublished/unaccepted changes to Substrate.

litep2p v0.1.0

This is the first release of litep2p, v0.1.0.

Support is added for the following:

• TCP + Noise + Yamux (compatibility with libp2p)
• /ipfs/identify/1.0.0
• /ipfs/ping/1.0.0
• Request-response protocol
• Notification protocol

The code quality is atrocious but it works and the second release focuses on providing high test coverage for the library. After that is done and most of the functionality is covered (unit, integration and conformance tests, benchmarks), the focus can be turned to refactoring the code into something clean and efficient.
