-# Changelog
-
-Release notes for Unsloth and Unsloth Studio.
-
-Unsloth Studio reads this file to show release notes inside the "New Unsloth
-version" update popup. Edit it here and the popup picks the change up on the
-next update check, with no release or rebuild required.
-
-## Format
-
-Every release is a level-2 heading whose first token is the version, optionally
-followed by a date:
-
-```md
-## 2026.7.6 - 2026-07-22
-```
-
-`## [2026.7.6] - 2026-07-22` and `## v2026.7.6` also work. Everything under a
-heading, up to the next level-2 heading, is that release's notes and renders as
-Markdown in the popup.
-
-Notes are matched to one exact version. When Studio offers an update to
-`2026.7.6` it renders the `2026.7.6` section and nothing else. If that section
-is missing, the popup links out to the online changelog rather than showing
-notes from an unrelated release, so a new version needs its own section here
-before its notes can appear.
-
-Keep the newest release at the top. Lead each bullet with the change itself:
-the collapsed popup highlights the first sentence and dims the rest.
-`## Unreleased` is ignored by the popup, so it is safe to stage notes there and
-rename the heading at release time.
-
-<!-- Add new releases directly below this line. -->
-
-## Unreleased
-
-## 2026.7.5
-
-### What's Changed
-
-- AMD support is here. Train, run RL, chat with and deploy 500+ models on
-  Radeon, Instinct, Ryzen and data center GPUs across Windows, WSL and Linux,
-  up to 2x faster with 70% less VRAM and no accuracy loss.
-- Intel XPU support lands in Studio, so Arc and Data Center GPUs run chat and
-  training alongside the NVIDIA, AMD and Apple paths.
-- Local speech to text dictation runs fully offline, with slim Whisper bundles
-  and a picker for custom models.
-- DoRA training is available in Studio, selectable next to LoRA and full
-  fine-tuning in the training tab.
-- The update popup previews release notes inline, pulled from this file and
-  matched to the exact version being offered.
-
-### AMD, 23 July update
-
-Our AMD collaboration, custom Triton kernels and math algorithms bring local
-training and inference to AMD hardware. The 23 July update builds on the
-[AMD release](https://github.com/unslothai/unsloth/releases/tag/v0.1.501-beta):
-
-- RDNA2 and Gorgon Halo are supported, and the installer no longer fails to
-  detect GPUs on Strix Halo and other AMD cards.
-- RDNA4 handling is better, and HIP and ROCm failures are caught and fixed
-  automatically instead of stopping the install.
-- Unified memory safetensors loading is 2x faster, with much faster gradient
-  checkpointing on unified memory devices.
-- Voice dictation through whisper.cpp has preliminary support.
-- Rollback environments left by installs no longer eat 5GB of disk. They are
-  cleaned up automatically.
-
-Optimized ROCm builds cover GGUF and safetensors inference, and ROCm
-compatibility is improved for MI300X and MI325X. Full guide:
-[unsloth.ai/docs/basics/amd](https://unsloth.ai/docs/basics/amd).
-
-### Running larger models
-
-- Automatic GPU placement, or pick exactly which GPUs and layers to use.
-- Move MoE expert layers into system memory so larger models fit.
-- Split a model across several GPUs, or use tensor parallelism.
-- Hardware settings are saved per model and quant.
-
-### Also in this release
-
-- Remote access with `unsloth studio --secure` over free HTTPS via Cloudflare.
-- Web search reads PDF papers and manuals, and parallel tool calls, reasoning
-  output and tool retries are more reliable.
-- The model download location is configurable, so weights can live on a second
-  drive instead of the default cache.
-- Stalled Hugging Face XET downloads retry over standard HTTP, and existing
-  GGUF files are reused instead of downloaded again.

-## 🚀 Unsloth Start
-
-[Unsloth Start](https://unsloth.ai/docs/integrations/unsloth-start) connects [Claude Code](https://unsloth.ai/docs/basics/claude-code), [Codex](https://unsloth.ai/docs/basics/codex) and other agents to local models with one command.
-
-Start Unsloth, load a model, open your project folder, then run:
-
-```bash
-unsloth start claude
-```
-
-Replace `claude` with any supported agent:
-
-| Agent | Command |
-| --- | --- |
-| Claude Code | `unsloth start claude` |
-| OpenAI Codex | `unsloth start codex` |
-| Hermes Agent | `unsloth start hermes` |
-| OpenClaw | `unsloth start openclaw` |
-| OpenCode | `unsloth start opencode` |
-| Pi Coding Agent | `unsloth start pi` |
-
-Claude Code, Codex, OpenCode and Pi can keep their current model and use Unsloth as a local
-subagent:
-
-```bash
-unsloth start claude --as-subagent --model unsloth/model-GGUF:quant
-```

 The Cloudflare tunnel is **off by default**: `-H 0.0.0.0` exposes the raw port only, not a public internet URL. Pair the wildcard bind with `--cloudflare` (`unsloth studio -H 0.0.0.0 --cloudflare`) to also publish a public `https://*.trycloudflare.com` link, or prefer `--secure` (above), which keeps the raw port private. `--cloudflare` has no effect on a loopback bind.
 
-On a wildcard bind Unsloth works out the address to share by asking `ifconfig.me` for the public IP, then asks `check-host.net` whether that port is reachable so it can tell you if a firewall is in the way. Both contact a third party. Set `UNSLOTH_STUDIO_DISABLE_PUBLIC_CHECK=1` to skip them; the banner then shows the LAN address and no reachability line.
-
 The first time Unsloth is published on a public URL (`--secure` or `--cloudflare`) with the auto-generated admin password still in place, it asks for a new admin password in the terminal (masked input with confirmation) before the public link goes up. Without an attached terminal it warns instead and keeps the bootstrap deadline: Unsloth shuts down after `UNSLOTH_STUDIO_BOOTSTRAP_TIMEOUT` (default 1 hour) unless the password is changed in the web UI.
 
 For headless setups that cannot answer that prompt, set the initial admin password non-interactively with `--password` (only takes effect when no password is set yet; if one already exists it is a hard error, so rotate later with `unsloth studio reset-password`):

-"""Measure where Unsloth Studio's startup time goes, per platform.
-
-Nothing measured this before: the backend logs "lifespan startup completed in X ms"
-but no test or CI job asserted a budget, and studio_test_kit discards the elapsed
-time of its /healthz poll. A first local run (Linux, warm cache, fast server CPU)
-found `import main` alone costs 6.6s before the server can bind, dominated by eager
-module-level imports pulled in by the `routes` package:
-
-    torch          1930 ms self
-    unsloth_zoo     914 ms self
-    routes          779 ms self
-    transformers    524 ms self
-
-Phases measured:
-  import   `python -X importtime -c "import main"`, top cumulative + per-package self
-  spawn    process start -> first byte on stdout
-  healthz  process start -> /api/health (or /healthz) answers 200
-  lifespan the backend's own "lifespan startup completed in X ms" log line
-
-Usage:
-    python scripts/profile_startup.py --repeats 3 --json out.json
-    python scripts/profile_startup.py --import-only     # no server, no port needed
