## 2.5.0 (2026-08-04)

### Features

* Added an MCP service that lets trusted MCP clients capture screenshots and control the keyboard and mouse with an API key, including a settings page for enabling it and regenerating the key
* Added coordinated device control so MCP, PicoClaw and manual input hand ownership over to each other instead of writing HID input at the same time
* Added remote keyboard lock indicators that show the target machine's Num Lock, Caps Lock and Scroll Lock state
* Added an optional SHA-256 checksum and cancellation to remote image downloads

### Bug Fixes

* Fixed the USB network gadget getting a random host-side MAC on every bind, which made the attached PC register a new network adapter after each reboot; both the device and host MAC are now derived from the chip UID (thanks to [@BeaconCat](https://github.com/BeaconCat))
* Fixed OLED sleep durations above 255 seconds being truncated, so the 5 min, 10 min, 30 min and 1 hour options now behave as selected
* Fixed the mounted image API returning an error in HID-Only mode
* Fixed image downloads and application updates interfering with each other when running at the same time
* Fixed Direct H.264 playback falling behind when the decoder queue backed up, by resynchronizing at the next key frame and preferring hardware decoding
* Added a warning when Direct and WebRTC H.264 stream modes are used at the same time
* Made the video input state shared between processes and read it without shell pipelines, so HDMI status stays consistent between `NanoKVM-Server` and `kvm_system`

### Performance

* Reduced latency in 60 Hz mode with decode-driven flow control, GOP-aware bounded queues, and dedicated writer goroutines with write deadlines so a slow client no longer stalls the others
* Integrated zero-copy H.264 capture into the video pipeline instead of relying on a preload hook
* Stopped HDMI capture when no user is logged in or all viewers are idle, reducing power consumption

### UI Improvements

* Tidied the image download dialog layout and truncated long file names in the upload box

### Localization

* Synchronized translations of other languages according to English

### Chores

* Split release automation into separate package, tag and release workflows, and produced identifiable build artifacts with checksums for pull requests
* Allowed overriding the builder image, installed `patchelf` in the build environment, and fixed the exit codes of `support/sg2002/build`
* Fixed slow container builds caused by uid/gid mismatch and reused existing container users and groups

## 2.4.3 (2026-06-09)

### Bug Fixes

* 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
* Stabilized PicoClaw session switching by waiting for gateway release, refreshing runtime status before reconnecting, rendering structured thought messages, and preventing history row overflow

### Performance

* Improved H.264 streaming client handling by reducing frame queue latency, using client snapshots for fanout, applying backend ICE server configuration, and cleaning up disconnected WebRTC clients more aggressively

### UI Improvements

* Refreshed desktop menu ordering and community links, including replacing the Discussion link with Discord

### Chores

* Removed the legacy H.264 stream package
* Updated PostCSS, refreshed the MSW worker, and added pnpm workspace build approvals

* Added French keyboard layout support and language options (thanks to [@ilyesAj](https://github.com/ilyesAj))

### Bug Fixes

* Hardened HID recovery and cleanup by adding non-blocking HID writes, bounded reopen retries, stale event draining, and release reports after write failures
* Fixed the `kvm_vision` project name and build output message in the SG2002 build script (thanks to [@Voranto](https://github.com/Voranto))

### UI Improvements

## 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.
