v0.5.0

2025-08-06

This release adds IPC transport support for local Ethereum node communication via Unix domain sockets.

Added

• IPC transport implementation using Unix domain sockets
• Connection pooling with NimblePool for efficient resource utilization
• Comprehensive IPC transport documentation and examples

Changed

• Updated transport documentation to include IPC transport options
• Enhanced examples with IPC transport usage
• Added IPC transport to the list of supported transport types
• Updated transport factory to support :ipc transport type

Full Changelog: v0.4.2...v0.5.0

v0.4.2

2025-07-04

This release intends to improve the reliability and fault-tolerance of the
transport layer.

Added

• Supervision Tree for Transport layer
• Websocket process registration with via-tuples through Registry

Full Changelog: v0.4.1...v0.4.2

v0.4.1

2025-06-14

Fixed

• Remove spaces from HTTP user-agent
• Fix WebSocket test flakiness caused by Registry name conflicts

Full Changelog: v0.4.0...v0.4.1

v0.4.0

2025-06-12

Added

• Websocket transport implementation.

• Support for subscriptions over websockets.

• Provider functions for websocket subscriptions (subscribe_blocks/0,
  subscribe_pending_transactions/0, subscribe_logs/0, subscribe_logs/1,
  unsubscribe/1).

• Internally added a MessageHandler responsible for handling incoming async
  messages/notifications and routing them to the appropriate caller.

• Internally added Exth.Rpc.Call struct that represents a chain of RPC calls
  that can be executed in sequence or as a batch.

• Internally changed Exth.Rpc.Client to use Exth.Rpc.Call structs that allow
  batch requests to be made piping requests, like:

  client
  |> Rpc.request("eth_blockNumer", [])
  |> Rpc.request("net_version", [])
  |> Rpc.send()

Changed

• Transport layer was responsible for serializing, deserializing and sending
  requests. Now, it's only responsibility is to send requests and receive
  responses, to keep its scope as minimal as possible.
• Encoding and decoding logic was moved to Exth.Rpc subdomain.

Fixed

• made :otp_app not required in the Provider configuration

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

v0.3.0

2025-04-11

Added

• Support for dynamic configuration through both inline options and application configuration
• examples directory with practical usage examples

Full Changelog: v0.2.2...v0.3.0

v0.2.2

2025-04-07

Changed

• Moved Exth.Rpc.Encoding.encode_request/1 logic to Exth.Rpc.Request.serialize/1
• Moved Exth.Rpc.Encoding.decode_response/1 logic to Exth.Rpc.Response.deserialize/1
• Removed Exth.Rpc.Encoding module
• Transport module does not receive an encoder/1 and decoder/1 option
  anymore. It's now direct to call Exth.Rpc.Request.serialize/1 and
  Exth.Rpc.Response.deserialize/1 functions.
• These changes aim to reduce the complexity of Exth.Rpc and Exth.Transport
  modules and make it easier to understand its internals.

Full Changelog: v0.2.1...v0.2.2

v0.2.1

2025-04-05

Changed

• Exth.Provider was refactored to reduce its complexity
• Fixed dialyzer warnings on Exth.Provider related to has no local return.
  Some types were fixed and the dialyzer warning does not appear anymore. No
  more warnings when defining providers.

Full Changelog: v0.2.0...v0.2.1

  • This change allows for more flexible usage patterns (pipes)
• Creation of request IDs on Exth.Rpc.Client.send/2 when no pre-assigned IDs
  are provided
• Creation of requests with no pre-assigned IDs with Exth.Rpc.request/2 and
  Exth.Rpc.Client.request/2

Changed

• Replaced Jason with JSON for JSON encoding/decoding
• Updated README.md for documentation purposes
