Thanks for the support for Qwen3.8-27B and Unsloth Desktop! This is a bug fix release with 170+ PRs.

* **MLX fixed** - Some MLX and Mac runtimes did not run correctly
* **LAN API keyless / password-less** is now supported
* **XET / HTTP download toggle** - clearer download progress
* **AMD bug fixes** for Strix Halo, all RDNA GPUs + 170 bug fixes

##### Features

* **Auto Compaction (Experimental)** for longer chats beyond context limits
* **Remote & LAN Access (Preview)** for easy network access without Cloudflare links
* **Faster Chat** - Improved streaming performance, reduced UI lag, and smoother long conversations.
* Support for **custom llama.cpp builds**. Toggles for Cache RAM, Mmap, Mlock, Checkpoints, Spe Decoding KV Cache, Vision On / Off
* [Unsloth Dynamic v3.0](https://unsloth.ai/docs/basics/dynamic-3.0-ggufs) is released. New Qwen3.8-27B Dynamic v3.0 GGUFs deliver >10% higher top-1 accuracy compared to everyone else. Works with Unsloth.

##### Auto compaction (Experimental)
You can now do long chats and surpass a model's context limit, with evicted turns
remaining searchable.
* Long local chats can continue past the context limit by rolling older turns out of
  active context.
* Auto compaction creates fresh context epochs instead of permanently trimming replies.
* Evicted conversations remain searchable, with improved fact recall.
* Context window information is shown before chat begins.

**How it works**
* Entire oldest turns are removed only when needed, never mid-message. The saved transcript stays unchanged.
* Evicted turns are indexed into a per-thread searchable archive using Unsloth's existing RAG pipeline (store, chunker, embedder, retrieval). Lexical search is prioritized because chat recall is usually exact matches like names, numbers, or IDs.
* A recall is forced during eviction instead of relying on the model to search itself. Later retrieval uses `search_conversation`.
* The archive persists across epochs, allowing future compactions to recover previously evicted context.
* No summarization: it showed little benefit and added ~190s per compaction.

##### Remote & LAN access (Preview)
Access Unsloth from another device on your network, managed from settings.
* New dedicated Settings section for remote access.
* Enable or disable LAN access without restarting.
* Supports connection addresses, QR codes, and optional auto-start.
* LAN access is disabled by default and requires changing the generated admin password.

##### Chat + Functionality improvements

* Long chats are faster with optimized streaming and thread handling.
* Projects organize chats, files, and workspaces together.
* Chats remember composer settings, system prompts, and model sampling options.
* Added prompt queueing and customizable keyboard shortcuts.
* Added `edit_file` tool for partial file modifications.
* Improved tool calling and MCP behavior.

##### Hardware + inference improvements

* Support for custom llama.cpp builds.
* Toggles for advanced settings - Cache RAM, Mmap, Mlock, Checkpoints, Speculative Decoding KV Cache, Vision On / Off
* Better validation for missing GPU support and oversized GGUF models.
* Improved MTP performance and VRAM handling.
* Better compatibility across ROCm, xFormers, and flash-attention setups.
* Added Intel XPU support.

##### API + serving

* Responses API supports structured output formatting.
* Improved recovery when llama-server crashes.
* Added OpenCode V2 support for `unsloth start`.

##### Hub + Desktop + training

* Hub supports more image/video workflows.
* Faster and improved GGUF downloads.
* Desktop packaging and permissions improved.
* Training scheduler and preprocessing improvements.
