AirSend v3.5.0

中文

v3.5.0 把最近两条主线能力正式合并进发布版本：一条是菜单栏设置入口与设置窗口整理，另一条是 DropZone 拖拽链路的重构与稳定性修复。

这次更新的重点不是再堆新功能，而是把过去“能用但不稳”的关键体验补到可持续发布的状态：

• 菜单栏新增更清晰的设置入口，状态栏交互路径更完整。
• DropZone 的触发、锚点定位、显示隐藏与拖拽接管逻辑重新梳理，明显减少文件拖拽时的“弹回”“静默消失”“位置错乱”和窗口被裁切。
• 本地文件拖拽识别与 drag session 维持逻辑更稳，对访达拖拽、菜单栏附近预热和进入目标区后的接管更可靠。
• macOS、Android、Magisk 模块和运行时协议版本统一对齐到 3.5.0，发布产物与运行时代码保持一致。

主要改动

• 合入状态栏设置窗口分支改动，补齐菜单栏设置入口。
• 合入 DropZone 重构分支改动，修复窗口错误出现在屏幕中央、半截裁切、难以触发、拖拽松手无响应和高概率回弹等问题。
• 调整 DropZone 触发带、keepalive 区域和拖拽接管顺序，让状态栏附近更容易拉起 DropZone，同时离开目标区后也能正确收起。
• 刷新 macOS .app、Android APK、Magisk 模块版本号和模块元数据。

发布资产

• AirSend-v3.5.0-macOS.zip
• AirSend_Magisk_v3.5.0.zip

更新建议

• 建议更新最新的 Mac 版本。
• Magisk 模块可以不更新，因为这次除了版本号之外没有任何改动。

v3.5.0 brings the two recent feature lines into one release: the new menu-bar settings entry and the DropZone drag-and-drop stability rewrite.

The point of this release is not to add flashy features, but to make the core workflow feel publishable and dependable:

• A cleaner settings entry is now available from the menu bar, with a more complete status-item workflow.
• DropZone trigger, anchoring, show/hide behavior, and drag-session ownership were reworked to reduce bounce-backs, silent dismissals, mispositioned windows, and clipped panels.
• Local-file drag detection and drag-session retention are more reliable, especially for Finder drags, status-bar prewarm, and handoff after entering the target zone.
• macOS, Android, the Magisk module, and runtime protocol strings are now aligned on version 3.5.0, so shipped assets match the running code.

Highlights

• Merged the status-bar settings window branch into the release line.
• Merged the DropZone refactor branch and fixed center-screen placement, half-clipped windows, hard-to-trigger activation, no-op drop release, and frequent drag bounce-back failures.
• Tuned the DropZone activation band, keepalive area, and drag handoff order so it appears more easily near the menu bar and dismisses correctly after leaving the target area.
• Refreshed the macOS .app, Android APK, Magisk module metadata, and release version strings.

Release Assets

• AirSend-v3.5.0-macOS.zip
• AirSend_Magisk_v3.5.0.zip

Update Recommendation

• Updating to the latest Mac build is recommended.
• You can skip updating the Magisk module, because this release does not change anything in it except the version number.

AirSend v3.0.1

AirSend 3.0.1 进一步稳定了校园网下的设备发现与列表保活，减少“设备突然消失”与反复全网扫描。
AirSend 3.0.1 further stabilizes campus-network discovery and device-list persistence, reducing sudden disappearances and unnecessary full-subnet rescans.

AirSend v3.0.0

中文

这次 GitHub 上正式发布的 v3.0.0，不仅包含最初 Release v3.0.0 提交里的大版本更新，也补齐了首发后继续验证和修复的那一批关键改动。

重点不只是继续打磨日常传输，而是把复杂校园网环境里最现实的几个痛点一起补上了：

• 不只是“能发现但几乎传不动”，还包括“切到校园网后设备列表经常空白”与“发现到了又很快消失”
• 不只是加了一条兼容链路，还把这条兼容链路的取消、超时回收、会话串包防护和体积边界一起收紧
• 不只是拖拽体验更顺手，DropZone 的预热、回弹防护和后台最小化也进一步稳定

复杂网络与校园网突破

• 新增手动 HTTP 兼容模式，默认关闭，默认仍优先保持 LocalSend 标准 HTTPS 传输。
• 当校园网里设备发现正常、但 HTTPS 数据面频繁超时或悬空时，可在 macOS 菜单栏 Advanced -> Compatibility Mode (HTTP) 手动切换到兼容链路。
• macOS 端新增 plain HTTP 接收器，并把局域网接收端口独立到 53318；Android 守护进程侧使用独立传输端口 53319，让发现面和数据面职责更清晰。
• 发送前会做真实数据面预检，并在 HTTPS / HTTP 之间选择当前真正可用的链路，减少“设备明明在线却一直发不出去”的假在线情况。
• Android -> Mac 的主动发送链路补上了 peer 记忆与连接重建逻辑，网络切换后更不容易掉进 No target found 或旧连接悬挂。
• Android 守护进程增加网络绑定变化检测与自重绑能力，热点、校园网、接口切换后的恢复速度更快。
• macOS 端新增了大网段校园网发现增强：当 UDP multicast 在 /16、/17 等校园网里失效时，会按 /24 切片向外扩散探测，不再只盯着当前一个小网段。
• 设备一旦被发现，Mac 会额外记住它最近可用的 IP，并通过轻量级 preferred host probe 做后台保活与冷启动回找，修复“菜单里搜不到 / 出现后又很快消失”的问题。

首发 3.0.0 之后补上的兼容链路加固

• campus fallback 现在加入了 session nonce 和来源 IP 绑定，降低旧包、错包、跨会话串包导致误判成功的概率。
• fallback 增加超时清理与取消能力，半传输中断、假 prepare 或用户手动取消时，不再轻易留下脏状态。
• fallback 默认不再每包同时做组播和广播双发，局域网噪音更小。
• fallback 体积边界收紧到 1 MB，避免大文件在弱网或拥塞 Wi-Fi 下放大内存与流量压力。
• HTTP 兼容模式保持手动开启，不会静默把原本的默认 HTTPS 传输自动降级成兼容链路。

DropZone 与拖拽体验升级

• 重做本地文件拖拽识别，只接受真实的本地文件拖拽，忽略文本选择、窗口移动或其他伪拖拽来源。
• 新增拖拽负载缓存与回读逻辑，修复 AppKit 在边界抖动时丢失 pasteboard 内容导致的“松手弹回”问题。
• DropZone 预热、显示、隐藏与最小化流程重新梳理，拖拽飞行中尽量不做破坏 session 的窗口层级变更。
• 边界命中、退出延迟和后台收起策略都做了收紧，拖拽目标更稳，失败时也更少打断操作。

传输与全链路稳定性

• macOS 出站发送器补充了更强的预检、重试与协议切换策略。
• Android 守护进程和 LocalSend patch 继续强化复杂网络下的链路恢复能力。
• Magisk 模块与 Android 侧 daemon 资产一并刷新，发版构建产物与运行时代码保持一致。

兼容性说明

• 默认安全模式仍然优先使用 HTTPS，继续保留与官方 LocalSend 的标准协议兼容能力。
• HTTP 兼容模式 是 AirSend 针对复杂校园网场景额外提供的能力，官方 LocalSend 当前不提供这条手动兼容路径。
• 复杂校园网下的“设备列表恢复与保活”能力现在也一并落地，不再只解决“传不出去”，还解决“设备经常看不见”。
• 建议家庭路由器、手机热点等正常局域网继续使用默认安全模式；只有在“能发现、但几乎传不动”的校园网环境下再手动打开兼容模式。

This published GitHub v3.0.0 release includes not only the original Release v3.0.0 commit, but also the critical follow-up fixes we added after continued real-world validation.

The breakthrough is no longer just "campus Wi-Fi can discover devices but can barely transfer":

• it also covers "after switching to campus Wi-Fi the device list is empty"
• and "the device appears once, then disappears again"

It also means the compatibility path is no longer just present; it is now tightened with better cancellation, timeout cleanup, session isolation, and payload boundaries.

Breakthroughs for campus and complex LAN environments

• Added a manual HTTP Compatibility Mode. It is off by default, and secure LocalSend-style HTTPS remains the default path.
• When discovery works on a campus network but the HTTPS data plane keeps timing out or hanging, you can manually switch macOS to Advanced -> Compatibility Mode (HTTP).
• macOS now has a dedicated plain-HTTP receiver and a separate LAN transfer port on 53318; the Android daemon uses its own transfer port 53319, keeping discovery and transport concerns cleaner.
• Before sending, AirSend now performs real data-plane preflight checks and chooses the transport that is actually reachable, reducing the classic “device looks online but transfers never start” failure mode.
• The Android -> Mac active-send path now remembers peers and rebuilds the connection state more reliably after network churn, reducing No target found and stale-route failures.
• The Android daemon now watches for binding changes and can rebind itself after hotspot, campus Wi-Fi, or interface transitions.
• macOS discovery now handles large campus subnets more aggressively: when UDP multicast is suppressed on /16 or /17 style LANs, it expands probing by /24 slices instead of staying trapped in a single local slice.
• Once a device has been found, macOS also remembers its last reachable IP and keeps it alive with a lightweight preferred-host probe, fixing the “device list goes blank again” problem after campus-network transitions or app restarts.

Compatibility-path hardening added after the first 3.0.0 commit

• The campus fallback path now uses a session nonce plus source-IP binding to reduce stale packets, wrong packets, and cross-session state pollution.
• Fallback now has timeout cleanup and real cancellation support, so interrupted transfers and fake prepare packets are less likely to leave dirty state behind.
• Fallback no longer defaults to dual multicast+broadcast sending for every packet, which reduces LAN noise.
• The fallback payload cap is now 1 MB, avoiding large-file memory and airtime amplification on congested Wi-Fi.
• HTTP Compatibility Mode remains manual and explicit instead of silently downgrading the default HTTPS path.

DropZone and drag-and-drop improvements

• Reworked local-file drag detection so only real local file drags are accepted; text selections, window moves, and other false-positive drags are ignored.
• Added staged drag payload caching and recovery to fix the AppKit boundary case where the pasteboard payload disappears and the drop “bounces back”.
• Reworked DropZone prewarm, show, hide, and minimize behavior to avoid window-layer changes that can break the drag session mid-flight.
• Tightened boundary handling, exit timing, and background minimization behavior so the target feels more stable and less disruptive during drag-and-drop.

Transport and end-to-end stability

• The macOS sender now uses stronger preflight, retry, and protocol-switching behavior.
• The Android daemon and LocalSend patches continue to harden recovery on unstable or policy-heavy LANs.
• The Magisk module and Android daemon assets have been refreshed together so release artifacts stay aligned with the runtime code.

Compatibility notes

• The default secure mode still prioritizes HTTPS and preserves standard protocol compatibility with official LocalSend in normal LAN environments.
• HTTP Compatibility Mode is an AirSend-specific answer for difficult campus-style networks; official LocalSend does not currently offer this manual compatibility path.
• The release also improves device-list recovery and keepalive behavior on campus LANs, not just the transfer path itself.
• For home routers and mobile hotspots, the default secure mode is still recommended. Turn on compatibility mode only for networks where discovery works but actual transfers repeatedly stall.

v2.4.2

中文

• 修复 Android 守护进程在网络切换后误绑定 rmnet/tun/Meta 的问题，恢复局域网发现与 HTTPS 传输稳定性。
• 修复 Mac 端在同一设备 fingerprint 对应 IP 变化时仍沿用旧地址的问题，设备重连和热点/IP 变化后可正确刷新目标。
• 修复 Android 文本 IPC 对多行与首尾空白的截断问题，剪贴板文本可完整传输。
• 保持 Android ↔ Mac 走 HTTPS，并补齐了热点/节点变化后的链路恢复逻辑。
• 改进模块内 APK/daemon 同步流程，升级后更容易保持二者版本一致。

English

• Fixed Android daemon binding to rmnet/tun/Meta after network changes, restoring stable LAN discovery and HTTPS transfers.
• Fixed the macOS app keeping stale peer IPs when the same device fingerprint appears on a new address, so reconnects and hotspot/IP changes now refresh the target correctly.
• Fixed Android text IPC truncation for multiline content and preserved leading/trailing whitespace for clipboard text.
• Kept Android ↔ Mac transfers on HTTPS and improved recovery after hotspot or node changes.
• Improved APK/daemon synchronization inside the Magisk module so upgrades are less likely to drift across components.

v2.4.1

• 修复：优化 Dock 拖拽判定，解决弹窗偶发消失且未发送的问题。
• Fix: improved Dock drag detection to prevent the popup from disappearing without sending.

v2.4

中文更新

• 改进拖拽触发逻辑：状态栏附近的拖拽判定区域更稳定，空闲慢检/拖拽快检切换更及时。
• 修复 Target Offline 相关卡住问题：离线时会明确失败反馈，避免弹窗长期停留。
• 优化设备展示：优先显示手机产品名称，模块设备副标题统一为 airsend module。
• 同步更新发送目标文案：DropZone 显示为 Send to <设备名>。
• 版本升级到 2.4，Magisk 模块已内嵌对应 APK 与最新 daemon。

English

• Improved drag trigger behavior near the menu bar with faster active drag detection and steadier idle polling.
• Fixed Target Offline stuck states with explicit failure feedback instead of lingering DropZone overlays.
• Refined device display: prefer product model names, with module subtitle shown as airsend module.
• Updated DropZone target text to Send to <device name>.
• Version bumped to 2.4; the Magisk module now bundles the matching APK and latest daemon.

AirSend v2.3.1

AirSend v2.3.1

• Fixed discovery reliability on macOS: Refresh now restarts discovery stack and auto-recovers from UDP transport failures.
• Bumped app/module version to 2.3.1.
• Updated Magisk module package to v2.3.1.

说明（简要）

• 修复 macOS 设备发现稳定性：Refresh 现在会重启发现服务，并在 UDP 失败时自动恢复。
• 应用与模块版本统一升级到 2.3.1。
• Magisk 模块版本升级到 v2.3.1。

AirSend v2.3

中文更新说明

AirSend 2.3 聚焦于三件事：设备列表去重、切网稳定性、以及 Android 模块体验完善。

亮点

• 设备列表改为按逻辑设备分组（别名 + 机型 + 类型），显著减少同名设备堆积。
• macOS 身份在切换 Wi-Fi / VPN / 代理网络时保持稳定，不再因切网频繁生成新设备身份。
• 同组发送支持候选自动回退：主候选失败时自动尝试组内其他候选，提升发送成功率。
• 冲突保护：同组多 fingerprint 同时在线时自动展开为多候选，避免误发。
• 清理策略优化：在选中单设备模式下仍保留离线清理定时器，陈旧设备不会长期残留。

交互与显示

• 新增原生风格 Auto Send Clipboard 开关（默认关闭）。
• 开启自动剪贴板时弹出兼容性说明：该功能需 Android AirSend 模块（root / Magisk / LSPosed 方案）。
• Android 模块设备在 macOS 菜单与 DropZone 中显示可读机型名（例如 OnePlus 13T），副标题固定为 airsend module。
• 优化设备项选中态布局、图标与间距。

构建与发布

• 新增一键脚本 build_magisk_payload.sh：自动编译 daemon + APK、替换模块目录并打包 Magisk ZIP。
• 版本统一更新至 2.3（macOS / Android app / 协议上报 / Magisk 模块）。

English Release Notes

AirSend 2.3 focuses on three areas: device-list deduplication, network-switch stability, and Android module UX.

Highlights

• Device list now uses logical grouping (alias + model + type), greatly reducing duplicate entries.
• macOS identity stays stable across Wi-Fi / VPN / proxy switches, avoiding unnecessary new device identities.
• Group-level send fallback is now supported: if the primary candidate fails, AirSend retries other candidates in the same group.
• Conflict-safe presentation: when multiple fingerprints in one group are online, entries are expanded to prevent mis-sends.
• Cleanup behavior improved: offline cleanup timer remains active even in single-device mode.

UX and Display

• Added a native-style Auto Send Clipboard toggle (default OFF).
• Enabling auto clipboard shows a compatibility dialog: this mode requires the AirSend Android module (root / Magisk / LSPosed setup).
• Android module peers now show readable model names (for example OnePlus 13T) in both menu and DropZone, with subtitle fixed as airsend module.
• Refined selected-row layout, icon sizing, and spacing in the device menu.

Build and Packaging

• Added build_magisk_payload.sh for one-shot daemon + APK build, module payload replacement, and Magisk ZIP packaging.
• Version synchronized to 2.3 across macOS, Android app, protocol version reporting, and Magisk module metadata.

AirSend v2.2

中文更新说明

• 修复 Android 分享分流：当分享目标是文件（如 .yaml）但 MIME 被标记为 text/plain 时，现优先按 EXTRA_STREAM 走文件发送，不再误走文本分支。
• 保留纯文本同步：仅在没有 EXTRA_STREAM 时，才按 EXTRA_TEXT 作为剪贴板文本发送。
• Magisk 模块小版本更新为 v2.2，已集成本次更新 APK。

安装方式

1. 下载并刷入 AirSend_Magisk_v2.2.zip
2. 重启设备
3. 打开 AirSend App 并验证分享 .yaml 文件

English Release Notes

• Fixed Android share routing: when a shared file (such as .yaml) is mislabeled as text/plain, AirSend now prioritizes EXTRA_STREAM and sends it as a file instead of falling into the text branch.
• Kept plain-text sync behavior: clipboard text sync is used only when EXTRA_STREAM is absent.
• Magisk module is bumped to v2.2 and includes the updated APK.

Install

1. Flash AirSend_Magisk_v2.2.zip
2. Reboot device
3. Open AirSend and verify .yaml file sharing

AirSend v2.1

AirSend v2.1

中文更新说明

• 拖拽分享体验优化：Drop Zone 不再在检测到拖拽后立即可见，而是靠近状态栏图标时再显示。
• 稳定性增强：拖拽开始时先预热窗口（定位并入层但保持不可见），减少拖拽过程中弹回/抖动问题。
• 显隐逻辑改进：拖拽进行中支持软隐藏（仅透明化不出层），远离图标可隐藏，回到图标附近可平滑恢复显示。
• 传输与 UI 细节优化：改进上传链路日志与临时文件处理，设备列表标题展示更清晰。

English Release Notes

• Improved drag-to-share UX: the Drop Zone no longer appears immediately on global drag detection; it appears when the cursor is near the menu bar icon.
• Better drag stability: the window is prewarmed at drag start (positioned and ordered in but invisible) to reduce bounce/flicker during active drags.
• Refined visibility control: while dragging, soft-hide is used (alpha only, no order-out), so the window can hide when far away and smoothly reappear near the icon.
• Transfer and UI refinements: improved upload logging/temp-file handling and clearer device title presentation in the menu.
