# CHANGELOG

<!-- %% CHANGELOG_ENTRIES %% -->

## 0.5.0 - 2026-06-18

### Added

- `Tundra.adopt/1` to take ownership of an already-created TUN device from an
  open file descriptor. The original descriptor is duplicated and closed, so it
  must not be used after a successful call.

### Changed

- **Breaking**: Raise the minimum required Elixir version to 1.18 (was 1.15).

## 0.4.1 - 2026-01-26

- Fix recv buffer size to account for TUN header on Darwin and Linux

## 0.4.0 - 2026-01-03

- **Breaking**: TUN header is now handled automatically. `recv/3` returns raw IP
  packets without the 4-byte header, and `send/3` accepts raw IP packets and
  prepends the appropriate header based on IP version detection.

- Add destination address support for point-to-point interfaces on macOS

- Validate list length before inspecting iovec in send_data.
