#### Motrix 2.0.0-beta.18

English | [简体中文](https://github.com/agalwood/Motrix/blob/v2.0.0-beta.18/docs/release-notes/2.0.0-beta.18.zh-CN.md)

Motrix 2.0.0-beta.18 updates the bundled aria2 engine and improves DNS
resolution reliability. It is intended for public distribution only after
every protected release gate passes.

##### Highlights

- Updates the bundled desktop aria2 engine to `1.37.0-motrix.4`, with pinned
  archives and binary checksums for every supported target.
- Adds **Auto**, **System DNS**, and **Built-in DNS** choices under Network
  settings on both the desktop app and Server web UI.
- In Auto mode, Motrix starts with aria2's built-in asynchronous resolver. If
  aria2 cannot contact any DNS server, Motrix switches the active engine
  session to the system resolver and retries the affected task once.
- Limits automatic fallback to recognized DNS transport failures. Deterministic
  DNS answers and unrelated network failures are not retried, and each task is
  retried at most once per session.
- Adds a localized notification when an automatic DNS fallback retry occurs.
- Adds Traditional Chinese (`zh-TW`) throughout the application.
- Expands the Plugin SDK development guide with clearer setup, capability,
  sandbox, packaging, and distribution guidance.

##### Before testing

This is prerelease software. Back up existing Motrix application data and
downloads before installing it. Migration from Motrix v1 data has not yet been
validated, so do not use your only copy of v1 data with this beta.

When practical, test v2 in parallel using a separate OS account, machine, or
Docker data directory. Do not rely on this beta for your only copy of important
downloads.

##### Planned downloads after release gates pass

| Distribution | Architectures | Planned output |
|--------------|---------------|----------------|
| macOS 12 or later | `arm64` (Apple Silicon), `x64` (Intel) | DMG and ZIP |
| Windows | `x64` | Unsigned NSIS installer (`.exe`) and ZIP |
| Linux | `x64`, `arm64` | DEB and RPM |
| Flatpak Native Host companion | `linux/x64`, `linux/arm64` | `Motrix-Native-Host-2.0.0-beta.18-linux-<arch>.tar.gz` |
| Docker Hub / GHCR | `linux/amd64`, `linux/arm64` | Immutable `2.0.0-beta.18` tag in both registries |
| Snap Store | — | Not published for this beta |

After every container gate passes, the versioned image references will be
`docker.io/motrixapp/motrix-server:2.0.0-beta.18` and
`ghcr.io/agalwood/motrix-server:2.0.0-beta.18`. See the
[Docker Server deployment guide](https://github.com/agalwood/Motrix/blob/v2.0.0-beta.18/docs/docker-server.md)
for storage, networking, and upgrade guidance.

##### Distribution notes

- AppImage is not published for this beta.
- Flatpak is validated separately and is not published by the release tag; the
  GitHub prerelease includes its Native Host companion archives.
- Windows `arm64` and all 32-bit packages are not available.
- Windows packages are unsigned and may trigger a Windows SmartScreen warning.
  Download them only from the official GitHub prerelease after it is published.
- Beta container tags are immutable and do not update `latest`, `stable`, or
  other stable floating tags.
- Snap is not published for this beta. Prerelease Snap runs stop after source
  validation, so they do not build Snap artifacts, upload Store revisions, or
  change `latest/edge`.

##### Feedback

Please report reproducible problems through
[GitHub Issues](https://github.com/agalwood/Motrix/issues). Include your
operating system, architecture, package type, and the steps needed to reproduce
