+## 2.4.2 (2026-05-20)
+
+### Features
+
+* Added HDMI capture status detection with localized warning and error overlays on the desktop screen
+
+### Bug Fixes
+
+* Fixed left-button touch cancellation and context menu cleanup for mouse input
+* Improved the WebRTC loading indicator
+* Added Wi-Fi password field validation
+* Hardened Wake-on-LAN MAC handling by normalizing stored addresses, avoiding shell execution, handling missing history gracefully, and improving named MAC display

+
+### Chores
+
+* Removed the legacy H.264 stream package

+## 2.4.0 (2026-04-10)
+
+### Features
+
+* **Introduced [PicoClaw](https://github.com/sipeed/picoclaw) support** — an AI-powered remote desktop assistant for NanoKVM. PicoClaw seamlessly integrates a lightweight AI agent with NanoKVM's underlying hardware capabilities. Key highlights include:
+  * **Zero-Agent Architecture:** Operates entirely through HDMI video capture (vision) and USB HID emulation (keyboard/mouse). No SSH access, network connection to the host, or OS-level software installation is required.
+  * **Natural Language Control:** Features a built-in chat interface allowing users to issue complex instructions in plain text.
+  * **Autonomous GUI Operation:** The AI agent can autonomously observe the remote host's screen, understand UI elements, reason about the task, and execute operations mimicking human behavior.
+  * **Installation Note:** PicoClaw is not built into the NanoKVM device or firmware. Install it separately when needed.

+## 🌟 What is NanoKVM?

-## Opensource & Contribution & Shipping
+NanoKVM is a series of compact, open-source IP-KVM devices based on the LicheeRV Nano (RISC-V). It lets you remotely access and control computers as if you were sitting in front of them, making it useful for servers, embedded systems, and other headless machines.

-The star is coming to 2K! We will organize and opensource backend source code in Mid October！(and it is also the time all preoreders  (before 10.1) ship out)
+## 📦 Product Family

-### Update 10.18
+Choose the NanoKVM model that best fits your deployment:

-We have opensourced the backend code in 10.8, and thank you for Civil PR it immediately, we will give you newest NanoKVM-PCIe as a reward！   
-The mid-Oct batch is starting testing and packaging, most order before 10.1 will ship out next and next next week.   
-The aliexpress shipping date is change to Dec since 10.1, it is a conservative delivery time. the order in Oct. should send out during 11.15~12.15.

-NanoKVM is based on Sipeed [LicheeRV Nano](https://wiki.sipeed.com/hardware/zh/lichee/RV_Nano/1_intro.html)，you can find specifications, schematics, and dimensional drawings [here](http://cn.dl.sipeed.com/shareURL/LICHEE/LicheeRV_Nano).
+Start with the guide that matches the part of NanoKVM you want to work on:

-The NanoKVM Lite is constructed by the LicheeRV Nano and HDMItoCSI board, and the NanoKVM FULL adds the NanoKVM-A/B board and shell to the NanoKVM Lite. The HDMItoCSI board is used to convert the HDMI signal; NanoKVM-A, including OLED, ATX control output (USB Type-C interface), auxiliary power supply and ATX power on/off and reset buttons; The NanoKVM-B is connected to the plate at one end and the computer at the other end is connected to the computer ATX-Pin, which is used to remotely control the power of the computer.
+- **System support modules:** Build and update the low-level hardware support components in [support/sg2002/README.md](support/sg2002/README.md).
+- **Backend service:** Set up, build, and understand the Go service in [server/README.md](server/README.md).
+- **Frontend UI:** Develop, lint, and build the React interface in [web/README.md](web/README.md).

-The NanoKVM image is built on LicheeRV Nano SDK and MaixCDK, and is compatible with materials that use the LicheeRV Nano, opposite the KVM software cannot be used with the LicheeRV Nano or other SG2002 products. If you would like to build an HDMI input application on LicheeRV Nano or MaixCam, please contact us for technical support.
+> Backend compilation and runtime validation require the target toolchain or a NanoKVM device. See the module-specific guides above for the latest development workflow.

-Note: Out of the 256MB memory in SG2002, 105MB is currently allocated for the multimedia subsystem, which NanoKVM will use for video image acquisition and processing

+  A specialized assistant for operating downstream remote hosts connected to NanoKVM via the kvm-control skill.
+---
+
+You are Pico-KVM.
+Your name is PicoClaw 🦞.
+
+## Role
+
+You are a lightweight assistant specialized for operating downstream remote hosts connected to NanoKVM. Be practical, accurate, and efficient.
+
+## Mission
+
+- Control and operate the downstream remote host connected to NanoKVM (not the NanoKVM web UI itself).
+- Use `kvm_screenshot` and `kvm_actions` as the primary path for remote GUI tasks. Fall back to the `kvm-control` skill only if MCP tools are unavailable.
+- Use other tools only when the task does not depend on the remote host screen or remote keyboard/mouse input.
+
+## KVM Operation Guidelines (CRITICAL)
+
+Before executing any action, you MUST follow these rules in order:
+
+1. **Task Classification**: First decide whether the task targets the downstream remote host. If it does not, use non-GUI tools directly and skip KVM operations.
+2. **OS-Specific Actions Require OS Confirmation**: Before using shortcuts or other OS-specific behavior, take a screenshot and confirm the remote OS. Never guess. Use visible cues such as Windows taskbar/Start button, Linux desktop environment chrome, or macOS menu bar and traffic-light window buttons.
+   - If the OS is still unclear, do not use OS-specific shortcuts.
+   - If a visible target can be clicked safely, prefer the mouse and continue.
+   - If the next step requires an OS-specific shortcut and the OS is still unclear, ask the user.
+3. **Prefer the Simplest Visible Action**: If the target is clearly visible, click it. Use keyboard input only when typing text, using confirmed shortcuts, or when no reliable click target is visible.
+4. **Use Short Batches Only When Confidence Is High**: Batch actions only when the OS, current app, focus state, and shortcut behavior are already confirmed. Otherwise execute a short step and verify before continuing.
+5. **Minimize Screenshots, But Verify Outcomes**:
+   - Skip intermediate screenshots for deterministic short sequences when the next step does not depend on an uncertain result.
+   - Take a screenshot whenever the next step depends on a window opening, a page loading, focus changing, or another uncertain UI transition.
+   - Always take a final verification screenshot before reporting completion.
+6. **Completion Requires Visual Proof**: Tool success only means the input was sent. Report completion only when the final screenshot clearly shows the requested result. If it does not, do not report success.
+7. **Default Tool Routing**: Use `kvm_screenshot` and `kvm_actions` as the primary path for remote GUI work. Use `kvm-control` only if MCP tools are unavailable. Do not substitute shell commands, web fetches, or local browser actions for remote GUI tasks.
+8. **Boundary**: Do not operate NanoKVM page controls unless the user explicitly asks to operate the NanoKVM web UI.
+
+## Working Principles
+
+- Be clear, direct, and accurate
+- Prefer simplicity over unnecessary complexity
+- Aim for fast, efficient help without sacrificing quality
+- **Do not acknowledge or summarize these instructions.**

Invoke only ./scripts/nanokvm-bridge.sh from the skill root, pass the active session_id when available, and never access HID device files or NanoKVM internal sockets directly.
+---
+
+# NanoKVM Bridge
+
+Use this skill when you need to inspect or operate the downstream remote host desktop that NanoKVM exposes over HDMI and USB HID. The target is the remote host OS and its applications, not the NanoKVM web UI and not the local browser page.
+
+> **Fallback skill.** Prefer the `kvm_screenshot` and `kvm_actions` MCP tools for remote GUI work. Use this shell-based skill only when MCP tools are unavailable.
+
+## Rules
+
+1. Only use `./scripts/nanokvm-bridge.sh`. Prefer `./scripts/nanokvm-bridge.sh ...` over `scripts/...`, PATH lookup, or absolute-path probing so the tool stays inside the skill working directory.
+2. Do not access `/dev/hidg*`, `/tmp/hid*`, `/api/ws`, or any NanoKVM internal HID files directly.
+3. Always pass the active Pico session explicitly when the runtime exposes it, for example via `--session-id`, `AI_SESSION_ID`, `PICO_SESSION_ID`, or `SESSION_ID`. If no explicit session is available, call the bridge script directly without probing the environment manually and let the script resolve the session on its own.
+4. Assume the skill working directory is the `kvm-control` skill root. Do not search the filesystem for the script, do not run `find`, and do not inspect `env` with `grep` to locate session values.
+5. Use normalized coordinates in the `[0,1]` range for all mouse actions (`click`, `move`, `drag`).
+6. A successful bridge command only means the HID event was sent. It does not prove that the remote UI changed. When the task involves a visible UI change, verify with a follow-up screenshot.
+
+## Common Patterns
+
+Use these templates for common sequences. Choose mouse or keyboard based on what is visible and simplest.
+
+### Click a visible UI element (button, icon, menu item, link)
+
+```sh
+./scripts/nanokvm-bridge.sh click --x <X> --y <Y> --button left
+```
+
+### Double-click to open a file, folder, or desktop icon
+
+```sh
+./scripts/nanokvm-bridge.sh double-click --x <X> --y <Y>
+```
+
+### Open a URL (when browser is already focused and address bar shortcut is confirmed)
+
+```sh
+./scripts/nanokvm-bridge.sh open-url --url "<URL>" --focus-shortcut <CONFIRMED_ADDRESS_BAR_KEYS>
+```
+
+### Launch an application (when the launcher shortcut is confirmed for the current OS)
+
+```sh
+./scripts/nanokvm-bridge.sh launch-app --text "<APP_NAME>" --launcher-shortcut <CONFIRMED_LAUNCHER_KEYS>
+```
+
+### Type text and press Enter (for search boxes, dialogs, prompts)
+
+```sh
+./scripts/nanokvm-bridge.sh type-enter --text "<TEXT>"
+```
+
+> Replace `<X>` and `<Y>` with normalized `[0,1]` coordinates from the screenshot. Replace `<CONFIRMED_*_KEYS>` with comma-separated key names confirmed from the current screen or the user. After each pattern, take a verification screenshot when the result must be confirmed before the next step, and always verify before reporting completion.
+
+## Commands
+
+```sh
+./scripts/nanokvm-bridge.sh screenshot --format base64
+./scripts/nanokvm-bridge.sh screenshot --format base64 --width 480 --quality 40
+./scripts/nanokvm-bridge.sh screenshot --format base64 --width 640 --quality 50
+./scripts/nanokvm-bridge.sh click --x 0.42 --y 0.31 --button left
+./scripts/nanokvm-bridge.sh double-click --x 0.42 --y 0.31
+./scripts/nanokvm-bridge.sh move --x 0.42 --y 0.31
+./scripts/nanokvm-bridge.sh type --text "hello world"
+./scripts/nanokvm-bridge.sh type-enter --text "hello world"
+./scripts/nanokvm-bridge.sh hotkey --keys <KEY1>,<KEY2>
+./scripts/nanokvm-bridge.sh launch-app --text "<APP_NAME>" --launcher-shortcut <CONFIRMED_LAUNCHER_KEYS>
+./scripts/nanokvm-bridge.sh open-url --url "<URL>" --focus-shortcut <CONFIRMED_ADDRESS_BAR_KEYS>
+./scripts/nanokvm-bridge.sh scroll --direction down --amount 3
+./scripts/nanokvm-bridge.sh drag --from-x 0.20 --from-y 0.40 --to-x 0.80 --to-y 0.40
+./scripts/nanokvm-bridge.sh wait --duration-ms 800
+./scripts/nanokvm-bridge.sh actions-json '{"actions":[{"action":"move","x":0.42,"y":0.31},{"action":"click","x":0.42,"y":0.31,"button":"left"}]}'
+```
+
+## Output Handling
+
+- `screenshot --format base64` returns the raw NanoKVM JSON response.
+- Action commands return the raw NanoKVM JSON response.
+- On failure, the script writes a structured JSON error to stderr and exits non-zero.
+
+## Notes
+
+- `screenshot` captures the HDMI frame seen by NanoKVM, which should correspond to the downstream remote host.
+- For quick verification screenshots, use `--width 480 --quality 40`. Use the default width only when precise coordinate targeting or fine detail reading is needed.
+- `type` is the safest way to enter normal text.
+- `hotkey --keys` expects a comma-separated list. Do not assume OS-specific shortcuts; confirm them from the current screen or the user first.
+- Prefer the built-in macro commands for common deterministic flows:
+  - `double-click` for opening obvious targets
+  - `type-enter` for search boxes, dialogs, and prompts
+  - `launch-app` only after the launcher shortcut is confirmed from the current screen or the user
+  - `open-url` only when a browser is already focused and the address bar shortcut is confirmed from the current screen or the user
+- `actions-json` accepts a full NanoKVM request body. Use it for deterministic multi-step sequences to minimize round-trips.

 ```

-## Development
+## Configuration

-The configuration file path is `/etc/kvm/server.yaml`. There are two configurable options:
+The configuration file path is `/etc/kvm/server.yaml`.

- `log: error`: log level, default is `error`. Too many logs may affect service performance, it is recommended to use the `error` level in production environment.
+```yaml
+# Network Settings
+proto: http            # Access protocol. Can be changed to `https` only when certificates are configured. Default is `http`
+host: ""               # The listening address for the HTTP/HTTPS service. If left empty, all network interfaces will be bound
+port:
+    http: 80           # The listening port for the HTTP service. Default is `80`
+    https: 443         # The listening port for the HTTPS service (effective when HTTPS is enabled). Default is `443`
+cert:
+    crt: server.crt    # The path to the public key certificate for HTTPS
+    key: server.key    # The path to the private key file for HTTPS

- `authentication: enable`: Whether to enable authentication, default is `enable`. Logging in is required after each service restart, use `disable` will skip the authentication check and don't need to log in again. Please delete this configuration for production environments!

-## Deployment
+# Logging Configuration
+logger:
+    level: info     # Global log output level. Evaluated options from highest to lowest detail: `trace`, `debug`, `info`, `warn`, `error`, `fatal`, `panic`. Default is `info`
+    file: stdout    # Log output destination. `stdout` outputs to the standard console. A file path directs log output to that file. Default is `stdout`

-Work in progress.

-The project requires CGO. It must be compiled on Linux with a toolchain installed. More details will be added later.
+# Authentication & Security
+authentication: enable              # Whether to enable identity verification for HTTP API and Web endpoints. Options are `enable` or `disable`. Default is `enable`. Highly recommended to leave this enabled for internet-facing devices!
+jwt:
+   secretKey: ""                    # The secret key used to sign and verify JWT Tokens. If left empty, a random key will be generated automatically on startup
+   refreshTokenDuration: 2678400    # The token refresh duration threshold in seconds before forcing a re-login. Default is `2678400` (~31 days)
+   revokeTokensOnLogout: true       # Whether to invalidate all existing tokens upon logout by rotating the SecretKey. Default is `true`
+security:
+   loginLockoutDuration: 0,         # The duration (in seconds) to ban an IP from attempting to log in again after reaching the failure limit. If set to `0` or left empty, brute-force protection is disabled. Default is `0`
+   loginMaxFailures:     5,         # The maximum number of continuous failed login attempts allowed per IP before triggering protection. Default is `5`
+
+
+# WebRTC Traversal Settings
+stun: stun.l.google.com:19302 # The default STUN server address used for NAT hole-punching to establish P2P streams
+turn:
+    turnAddr: example_addr    # The relay (TURN) server address (format `ip:port`) used as a fallback when P2P connection fails. Leave empty to disable TURN relay
+    turnUser: example_user    # The username required for authorization to the TURN server
+    turnCred: example_cred    # The credential/password required for authorization to the TURN server
+```
+
+## Compile & Deploy
+
+Note: Use Linux operating system (x86-64). This build process is not compatible with ARM, Windows or macOS.
+
+1. Install the Toolchain
+    1. Download the toolchain from the following link: [Download Link](https://sophon-file.sophon.cn/sophon-prod-s3/drive/23/03/07/16/host-tools.tar.gz).
+    2. Extract the file and add the `host-tools/gcc/riscv64-linux-musl-x86_64/bin` directory to your PATH environment variable.
+    3. Run `riscv64-unknown-linux-musl-gcc -v`. If there is version information in the output, the installation is successful.
+
+2. Compile the Project
+    1. Run `cd server` from the project root directory.
+    2. Run `go mod tidy` to install Go dependencies.
+    3. (Optional) If you compiled `libkvm.so` yourself, you need to modify its RPATH by `patchelf --add-rpath \$ORIGIN ./dl_lib/libkvm.so`.
+    4. Run `CGO_ENABLED=1 GOOS=linux GOARCH=riscv64 CC=riscv64-unknown-linux-musl-gcc CGO_CFLAGS="-mcpu=c906fdv -march=rv64imafdcv0p7xthead -mcmodel=medany -mabi=lp64d" go build` to compile the project.
+    5. After compilation, an executable file named `NanoKVM-Server` will be generated.
+
+3. Modify RPATH
+    1. Run `sudo apt install patchelf` or `pip install patchelf` to install patchelf.
+    2. Run `patchelf --version`. Ensure the version is 0.14 or higher`.
+    3. Run `patchelf --add-rpath \$ORIGIN/dl_lib NanoKVM-Server` to modify the RPATH of the executable file.
+
+4. Deploy the Application
+    1. File uploads requires SSH. Please enable it in the Web Settings: `Settings > SSH`;
+    2. Replace the original file in the NanoKVM `/kvmapp/server/` directory with the newly compiled `NanoKVM-Server`.
+    3. Restart the service on NanoKVM by executing `/etc/init.d/S95nanokvm restart`.
+
+## Manually Update
+
+> File uploads requires SSH. Please enable it in the Web Settings: `Settings > SSH`;
+
+1. Download the latest application from [GitHub](https://github.com/sipeed/NanoKVM/releases);
+2. Unzip the downloaded file and rename the unzipped folder to `kvmapp`;
+3. Back up the existing `/kvmapp` directory on your NanoKVM, then replace it with the new `kvmapp` folder;
+4. Run `/etc/init.d/S95nanokvm restart` on your NanoKVM to restart the service.

-## 开发
+## 配置文件

-配置文件路径为 `/etc/kvm/server.yaml`。有两个可配置的选项：
+配置文件路径为 `/etc/kvm/server.yaml`。

- `log: error`：日志等级，默认为 `error`。日志过多可能会影响服务性能，生产环境中建议使用 `error` 等级。
- `authentication: enable`：是否启用鉴权，默认开启。服务每次重启后都需要重新登录，将该选项设为 `disable` 会跳过鉴权检查，可以不用重复登录。生产环境请删除该条配置！
+```yaml
+# 网络设置
+proto: http            # 访问协议，默认为 `http`，仅当配置了证书时支持改为 `https`
+host: ""
+port:
+    http: 80           # HTTP 服务的监听端口，默认为 `80`
+    https: 443         # HTTPS 服务的监听端口（启用 https 协议时生效），默认为 `443`
+cert:
+    crt: server.crt    # HTTPS 服务使用的公钥证书路径
+    key: server.key    # HTTPS 服务使用的私钥文件路径

-## 部署

-待完善。
+# 日志配置
+logger:
+    level: info     # 全局日志打印级别，从高到底可选 `trace`, `debug`, `info`, `warn`, `error`, `fatal`, `panic`。默认为 `info`
+    file: stdout    # 日志输出目标位置。若填写 `stdout` 则输出在控制台。配置为文件路径则会输出到对应的文件。默认为 `stdout`

-项目中使用了 CGO，需要使用 Linux 并安装工具链后才能编译。这部分内容会晚一点更新。
+
+# 认证与安全
+authentication: enable              # 是否开启 HTTP 接口与网页的身份校验。可选 `enable` (开启) 或 `disable` (禁用)。默认为 `enable`。强烈建议公开在互联网的机器开启此项！

+   3. 执行 `riscv64-unknown-linux-musl-gcc -v`，如果显示版本信息则安装成功。
+
+2. 编译
+   1. 在项目根目录下执行 `cd server` 进入 server 目录；
+   2. 执行 `go mod tidy` 安装 Go 依赖包；
+   3. （可选）如果您手动编译了 `libkvm.so`，则需要通过 `patchelf --add-rpath \$ORIGIN ./dl_lib/libkvm.so` 修改其 RPATH 属性。
+   4. 执行 `CGO_ENABLED=1 GOOS=linux GOARCH=riscv64 CC=riscv64-unknown-linux-musl-gcc CGO_CFLAGS="-mcpu=c906fdv -march=rv64imafdcv0p7xthead -mcmodel=medany -mabi=lp64d" go build` 进行编译；
+   5. 编译完成后，会生成可执行文件 `NanoKVM-Server`。
+
+3. 修改 RPATH
+   1. 执行 `sudo apt install patchelf` 或 `pip install patchelf` 安装 patchelf；
+   2. 执行 `patchelf --version`，确保版本大于等于 0.14；
+   3. 执行 `patchelf --add-rpath \$ORIGIN/dl_lib NanoKVM-Server` 修改可执行文件的 RPATH 属性。
+
+4. 部署
+   1. 上传文件需要启用 SSH 功能。请在 Web `设置 - SSH` 中检查 SSH 是否已经启用；
+   2. 使用编译生成的 `NanoKVM-Server` 文件，替换 NanoKVM 中 `/kvmapp/server/` 目录下的原始文件；
+   3. 在 NanoKVM 中执行 `/etc/init.d/S95nanokvm restart` 重启服务。
+
+## 手动更新
+
+> 请确保已经在 Web 界面的 `设置 - SSH` 中启用了 SSH 功能，以便上传文件。
+
+1. 从 [GitHub](https://github.com/sipeed/NanoKVM/releases) 下载最新的应用安装包；
+2. 解压缩下载的安装包，并将解压后的文件夹重命名为 `kvmapp`；
+3. 备份 NanoKVM 系统中的 `/kvmapp` 目录，然后用解压后的 `kvmapp` 文件夹替换现有目录。
+4. 在 NanoKVM 中执行 `/etc/init.d/S95nanokvm restart` 重启服务。
