+# 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.
+
+
+
+## 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.

+"""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
+
+Exit code is 0 unless --max-healthz-seconds is given and exceeded.

+The FIFO queue itself is unit-tested in test_llama_admission.py; here we exercise

+"""Ordering rules for the early admission release at ``data: [DONE]``.
+
+Freeing the llama-server slot at the sentinel is only correct when two things hold, and on a
+one-slot backend both are load-bearing:
+
+1. The release happens *before* the sentinel reaches the ASGI ``send()``. Starlette's
+ ``stream_response`` suspends the body iterator at its ``yield`` for the whole of
+ ``await send(...)``, and uvicorn's ``send()`` awaits ``flow.drain()`` on a write-paused
+ transport, so a client that stops reading parks the generator there indefinitely. Starlette
+ never ``aclose()``s a body iterator either, so that generator's ``finally`` is left to GC.
+
+2. The sentinel really means "llama-server is done with this request". Two other emitters end
+ in the same bytes: ``_openai_stream_error_sse``, yielded from inside the still-suspended
+ generator's ``except`` block, and the cancel path, which breaks the read loop while the sync
+ generator is still parked on a yield inside ``_open_stream``'s httpx client.

+"""An accuracy floor for the plan-without-action classifier, on real model output.
+
+The rest of the tool-loop suites pin behaviour on hand-written example sentences,
+which is how the patterns here were tuned. That says nothing about how often the
+classifier is right on what models actually emit, so this file scores it against a
+corpus captured from local models (``tests/data/plan_vs_answer.jsonl``).
+
+How the corpus was built: three GGUF models (Qwen3-0.6B, Qwen3-1.7B,
+Llama-3.2-1B-Instruct) were driven through llama-server with the real Studio tool
+schemas over prompts spanning tool-requiring questions, questions needing no tool,
+list-formatted answers, ambiguous requests, non-English, and follow-ups issued after
+a tool had already run. Turns cut off by the token cap were dropped, since a
+truncation is not a stall.
+
+Every turn here is a *finished answer*: the turn called no tool, and when the
+production nudge was appended and the turn regenerated three times, not one retry
+produced a tool call. A forceful re-prompt could not extract an action, so there was
+no action left to take. Nudging these is wasted work, and in the GGUF loop the
+retry's text can then be discarded, which costs the user a visible answer.
+
+Measured when this landed, over the 300 turns:
+
+ tree nudged retry discarded
+ origin/main (pre-PR) 36 (12.0%) 60 (20.2%)
+ this PR 5 ( 1.7%) 1 ( 0.3%)
+
+The budgets below sit above the measured counts so that innocuous wording changes
+do not fail the build, and far below the pre-PR counts so a real regression does.
+A failure prints the offending turns: fix the pattern, or if the turn really is a
+stall, correct its label here.

+"""Release notes for the update popup, sourced from CHANGELOG.md.
+
+Notes are keyed to one exact version: the popup asks for the version it is
+offering and gets that section or nothing, so an older release's notes can
+never appear next to a newer update.
+
+The remote copy on the default branch wins over the bundled one, since the
+offered version is newer than the installed checkout. Both reads are lazy,
+cached and skipped when update checks are off.
