## \[Unreleased\]

## 2026-05-14: v0.601.0

### Changed

- Bumped to holochain 0.6.1

## 2026-02-13: v0.600.3-rc.0

### Changed

- Holochain is now run with the iroh transport. The argument `--signaling-url` has been replaced with `--relay-url`.

### Removed

- Removed CLI option `--transport` as holochain is run with `quic` iroh transport.

## 2026-01-22: v0.600.2-rc.0

### Changed

- Added a CLI option `--transport` to choose between `quic` and `webrtc`. `quic` is used in combination with the iroh transport in Holochain, `webrtc` with tx5. The default transport in Holochain is iroh, so the default for hc-spin is `quic`. If no transport option is passed in on the command line, `quic` is used.

## 2025-07-09: v0.500.2

### Fixed
