- **added** — Validates every source updater manifest against allowlisted basenames, file sizes, and SHA-512 values of verified platform artifacts
- **added** — Regenerates published Linux and Windows updater manifests from the canonical verified package set with exactly one DEB and one RPM entry per Linux feed
- **added** — Adds real-shape Linux regressions for duplicate-identical RPM entries on both x64 and arm64 with negative coverage for conflicting duplicates
- **added** — Ground-up desktop rebuild with Electron 43, React 19, and TypeScript 7 including customizable Dashboard, dark mode, and cross-platform application menu
- **added** — Host-neutral download core for both desktop app and Node/Web Server with SQLite session recovery, tracker management, UPnP/NAT-PMP, and HTTP, FTP, BitTorrent, and magnet support
- **added** — MDXP-based integration for official CLI and browser handoff including local discovery and device-code pairing for remote Server instances
- **added** — QuickJS plugin sandbox with capability consent, bundled builtin plugins, and in-app plugin marketplace
- **added** — Persistent multi-architecture Server containers for NAS and home-server deployments published to both Docker Hub and GHCR
- **changed** — Accepts and collapses only duplicate entries whose basename, size, and SHA-512 metadata are identical while keeping unknown assets, casing changes, missing packages, and conflicting duplicates fail-closed
- **changed** — Snap is not part of the beta.12 distribution with protected prerelease Snap runs stopping after source validation
- **removed** — AppImage is not published for this beta

#### Motrix 2.0.0-beta.12

English | [简体中文](https://github.com/agalwood/Motrix/blob/v2.0.0-beta.12/docs/release-notes/2.0.0-beta.12.zh-CN.md)

Motrix 2.0.0-beta.12 is the next Motrix Turbo beta intended for public
distribution after every protected release gate passes. It continues public
validation of the rebuilt v2 desktop app and headless server, shared download
core, MDXP integrations, and sandboxed plugin system.

Motrix 2.0.0-beta.11 was not published. All five desktop builds and all three
Finalize jobs completed, but assembly rejected the real Linux updater manifest
shape before a release bundle was created. The
[beta.11 historical record](https://github.com/agalwood/Motrix/blob/v2.0.0-beta.12/docs/release-notes/2.0.0-beta.11.md)
preserves the exact outcome.

##### Release reliability updates

- Validates every source updater manifest against the exact allowlisted
  basenames, file sizes, and SHA-512 values of the verified platform artifacts.
- Accepts and collapses only duplicate entries whose basename, size, and
  SHA-512 metadata are identical. Unknown assets, casing changes, missing
  packages, and conflicting duplicates remain fail-closed.
- Regenerates the published Linux and Windows updater manifests from the
  canonical verified package set instead of copying source metadata verbatim.
  Each Linux feed therefore contains exactly one DEB and one RPM entry.
- Retains the macOS canonicalization introduced in beta.11: source ZIP and DMG
  entries are validated before the combined updater feed is reduced to one
  verified ZIP for Intel and one for Apple Silicon.
- Adds real-shape Linux regressions for duplicate-identical RPM entries on both
  x64 and arm64, together with negative coverage for conflicting duplicates.
- Exercises the complete beta.11 five-platform release inputs through local
  assembly and final update-manifest verification: 17 release assets and four
  beta updater manifests pass the recovered path.
- Keeps Windows `x64` packages explicitly unsigned while retaining final
  package verification before release.
- Retains the complete desktop platform-set gate: every desktop target must
  finalize before assembly and every canonical updater manifest must pass
  final verification before publication.

##### Snap beta policy

Snap is not part of the beta.12 distribution. Protected prerelease Snap runs
stop after source validation, so they do not build Snap artifacts, upload Store
revisions, or change `latest/edge`. Stable Snap publication retains its
complete two-architecture verification and protected Store gates.

##### Highlights

- A ground-up desktop rebuild with Electron 43, React 19, and TypeScript 7,
  including a customizable Dashboard, dark mode, a cross-platform application
  menu, and clearer task-inspector feedback.
- One host-neutral download core for both the desktop app and the Node/Web
  Server, with SQLite session recovery, tracker management, UPnP/NAT-PMP, and
  HTTP, FTP, BitTorrent, and magnet support.
- MDXP-based integration for the official CLI and browser handoff, including
  local discovery and device-code pairing for remote Server instances.
- A QuickJS plugin sandbox with capability consent, bundled builtin plugins,
  and an in-app plugin marketplace.
- Persistent, multi-architecture Server containers for NAS and home-server
  deployments, published to both Docker Hub and GHCR after the desktop release
  succeeds.

##### Before testing

This is prerelease software. Back up your 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. Please do not rely on this beta for your only copy of
important downloads.

##### What to test

- HTTP, FTP, BitTorrent, and magnet downloads, including pause/resume and
  session recovery
- Desktop integrations, browser and
