## 🌟 Summary

Ultralytics **8.4.120** improves CUDA training determinism and TensorFlow export reliability, while expanding documentation for LLM workflows and AI coding-agent integrations. 🚀

## 📊 Key Changes

- **Deterministic CUDA anchor generation** by @glenn-jocher
  - Replaced CUDA cumulative-sum operations with deterministic `arange`-based generation when creating detection anchors.
  - Removes recurring `cumsum_cuda_kernel` warnings during deterministic training.
  - Preserves runtime device handling for traced and TorchScript GPU models, avoiding device information being incorrectly fixed during tracing.

- **More reliable TensorFlow exports** 🛠️
  - Removed the obsolete NVIDIA package index from TensorFlow and non-YOLO export dependency installation.
  - `onnx-graphsurgeon` can now be installed directly from PyPI, reducing DNS and connectivity issues—especially in CPU-based CI environments and isolated export setups.

- **New Ultralytics LLM documentation** 🤖
  - Documents the OpenAI-compatible `LLM` interface for text, image, streaming, asynchronous, provider-specific, and YOLO-combined workflows.
  - Provides examples for OpenAI-compatible services such as DeepSeek, Kimi, Z.AI GLM, OpenRouter, and local servers.
  - Updates the default documented and runtime model to `gpt-5.6-luna`.

## Verify Docker Image Signature

All LiteLLM Docker images are signed with [cosign](https://docs.sigstore.dev/cosign/overview/). Every release is signed with the same key introduced in [commit `0112e53`](https://github.com/BerriAI/litellm/commit/0112e53046018d726492c814b3644b7d376029d0).

**Verify using the pinned commit hash (recommended):**

A commit hash is cryptographically immutable, so this is the strongest way to ensure you are using the original signing key:

```bash
cosign verify \
  --key https://raw.githubusercontent.com/BerriAI/litellm/0112e53046018d726492c814b3644b7d376029d0/cosign.pub \
  ghcr.io/berriai/litellm:v1.96.2
```

**Verify using the release tag (convenience):**

Tags are protected in this repository and resolve to the same key. This option is easier to read but relies on tag protection rules:

```bash
cosign verify \

# Highlights

* **Ray Data:** In this Ray release, we've enabled `DataSourceV2` by default (#64821), so `read_parquet` and friends use the new scan/listing infrastructure with row-group-aware chunking and predicate splitting. Hash Shuffle V2 eliminates the aggregator actor pool. V1 had to provision that pool up front from an estimate of the input size, and its actors accumulated partition shards in actor heap memory, invisible to Ray and unspillable, until finalization. V2 replaces it with two stateless task-based operators, ShuffleMapOp --> ShuffleReduceOp, that pass shards through the object store, so intermediate state spills under pressure and no capacity has to be reserved in advance. The map/reduce barrier itself remains in both designs.
* HashShuffleV2 supports `join` ([#63598](https://github.com/ray-project/ray/pull/63598), [#64538](https://github.com/ray-project/ray/pull/64538), [#64687](https://github.com/ray-project/ray/pull/64687)). This lets shuffles reuse standard map/reduce scheduling, backpressure, and resource accounting.
* **Ray Serve:** The HAProxy ingress is now distributed as the `ray-haproxy` PyPI package instead of being compiled into images, and it is the default HAProxy binary (#64141, #64163, #64164). We've also added gRPC support to the HAProxy direct-ingress path, including streaming, metrics, and custom request IDs (#63735, #64310, #64166, #64112). For Ray Serve LLM, we've added experimental KV-cache-aware request routing that tracks replica KV state through an event plane, tokenizes before routing, and routes on prefill/decode token load (#64084, #64085, #64097, #64224, #64327, #64400). KV cache-aware routing’s complete support will land in 2.58.
* **Ray Core:** We've added an embedded RocksDB storage backend for GCS fault tolerance (REP-64), selectable with `RAY_gcs_storage=rocksdb` and `RAY_gcs_storage_path` (#63657). GCS fault tolerance no longer requires an external Redis instance. We've also added a public API for topology-aware scheduling (#63479, #63740).

# Ray Data

# Keras 3.12.4

Keras 3.12.4 is a security patch release that hardens dataset loading and model file handling against insecure deserialization and decompression-bomb attacks.

## Security Fixes

* **Restrict unpickling when loading IMDB and Reuters datasets** — Replaces `np.load(allow_pickle=True)` with a restricted unpickler that only permits numpy array reconstruction, preventing arbitrary code execution via crafted `.npz` files (CWE-502). ([#23047](https://github.com/keras-team/keras/pull/23047)) by @LinZiyuu
* **Verify all intermediary H5 groups when navigating H5 files** — Manually resolves nested H5 group paths to verify group types at each step, preventing potential path traversal. ([#23168](https://github.com/keras-team/keras/pull/23168)) by @hertschuh
* **Reject decompression-bomb members on the `.keras` asset extraction path** — Adds per-member decompression-ratio checks before extracting `.keras` archives to disk, preventing disk-exhaustion attacks via crafted archives. ([#23101](https://github.com/keras-team/keras/pull/23101)) by @LinZiyuu
* **Restrict unpickling when loading CIFAR datasets** — Replaces bare `cPickle.load` in CIFAR-10/100 batch loading with the numpy-only `RestrictedUnpickler`, blocking arbitrary code execution via pickle gadgets. ([#23252](https://github.com/keras-team/keras/pull/23252)) by @SABITHSAHEB

## v3.0.0

Release date: July 29, 2026

| Milvus Version | Python SDK Version | Node.js SDK Version | Java SDK Version | Go SDK Version |
| -------------- | ------------------ | ------------------- | ---------------- | -------------- |
| 3.0.0          | 3.0.1              | 3.0.3               | 3.0.5            | 3.0.0          |

Milvus 3.0.0 is officially released! Building on the lake-native architecture introduced in [3.0-beta](https://milvus.io/docs/release_notes.md#v30-beta), this release completes what the beta started: External Collection covers more lakehouse workflows; schema supports online add / backfill / drop; the sparse index is rebuilt around SINDI; StructArray and faceted search round out the retrieval engine; FAISS passthrough, and TEXT extend index and modality choices; and Woodpecker runs as a standalone service.

If you are new to the 3.0 line, the Core 3.0 features recall section below summarizes the capabilities introduced in 3.0-beta; the [3.0-beta release notes](https://milvus.io/docs/release_notes.md#v30-beta) have the full write-ups.

### What's new in 3.0.0 (since 3.0-beta)

#### External Collection: more complete lakehouse workflows

3.0-beta introduced External Collection: reference lake files in place, build indexes, and search them without copying data into Milvus. This release extends it toward complete lakehouse retrieval workflows. External fields can now feed function output fields such as BM25 sparse vectors, MinHash signatures, and text embeddings, so text and model-derived retrieval fields are built inside Milvus without copying the source table. Refresh also supports additive schema evolution: when the external table gains new columns, Milvus patches the affected segments instead of rebuilding the collection.

This release also adds a `milvus-table` external format that treats Milvus Snapshot metadata and Storage V3 manifests as an external source, so a collection snapshot can itself be served as an external table — batch and serving systems get a shared, manifest-backed view of the same data.

<img width="1250" height="560" alt="peft-v0 20 0" src="https://github.com/user-attachments/assets/6194fae9-f3c3-48ca-b43b-40c774bfe6eb" />

This release adds no less than nine new PEFT methods and puts a lot of work into the surrounding infrastructure, for example adding a new image generation benchmark for the method comparison suite and greatly improving the documentation structure.

## New Methods

### HiRA

@hqsiswiliam added ["HiRA: Parameter-Efficient Hadamard High-Rank Adaptation for Large Language Models"](https://openreview.net/forum?id=TwJrTz9cRS) to PEFT (#2668). Instead of adding the low-rank product `BA` to the base weight, HiRA multiplies it elementwise (Hadamard product) with the frozen base weight. Because the base weight itself is full rank, the resulting update is no longer constrained to be low rank, while the trainable parameter count stays the same as LoRA's.

### GLoRA

@not-lain contributed GLoRA: ["One-for-All: Generalized LoRA for Parameter-Efficient Fine-Tuning"](https://arxiv.org/abs/2306.07967) in #3098. It is a flexible PEFT method that extends LoRA with configurable weight, activation, and bias adaptation, delivering richer fine-tuning with no extra inference cost. Use it when you need per-layer flexibility or stronger adaptation than vanilla LoRA. Skip it for non-Linear layers (e.g. Conv/Embedding) or when standard LoRA is already sufficient and simplicity matters.

### BEFT

@whubaichuan added ["BEFT: Bias-Efficient Fine-Tuning of Language Models"](https://arxiv.org/abs/2509.15974v2) in #3195. BEFT builds on the observation that fine-tuning bias terms alone can be competitive in low-data regimes, but goes further: rather than training *all* biases, it targets the value projection by default, as the authors found this to be most efficient. This brings the trainable parameter count down to roughly 0.01% of the total parameters.

# Version 3.11.0 (July 27, 2026)

## Engine

1. [4787c809](https://github.com/google-deepmind/mujoco/commit/4787c809) Added [geom/surfacevel](https://mujoco.readthedocs.io/en/stable/XMLreference.html#body-geom-surfacevel): the velocity of a geom's surface as seen by contacts, given as a velocity field with a constant component and a rotational component about the geom frame origin. This allows conveyor belts, treadmills and turntables to be modeled with static geoms and no degrees of freedom: friction drives touching bodies along the motion of the surface, with the field projected onto each contact's tangent plane. Surface velocities compose correctly with each other and with body motion. Note that the contact rows of `mjData.efc_vel`, and the constraint-state sensors that read them, report the velocity relative to the moving surface rather than to the geom, since that is the quantity the constraint acts on; for geoms without `surfacevel` the two are identical. Contact-point visualization draws an arrow along the surface velocity at contacts with moving surfaces.

2. [a264d0bc](https://github.com/google-deepmind/mujoco/commit/a264d0bc) Added [geom/adhesion](https://mujoco.readthedocs.io/en/stable/XMLreference.html#body-geom-adhesion) and [pair/adhesion](https://mujoco.readthedocs.io/en/stable/XMLreference.html#contact-pair-adhesion): an adhesive force associated with a contact, useful for modeling sticky materials. Contacts can pull with up to the given force before breaking, and the friction budget becomes $\mu(f_N + \text{adhesion})$. Combined with [gap](https://mujoco.readthedocs.io/en/stable/XMLreference.html#body-geom-gap), adhesive contacts apply "adhesion at a distance", useful for modeling magnets. Resting penetration is unaffected by adhesion. [mj_contactForce](https://mujoco.readthedocs.io/en/stable/APIreference/APIfunctions.html#mj-contactforce) reports the net interface force, whose normal component can now be negative.

3. [f0fa3d82](https://github.com/google-deepmind/mujoco/commit/f0fa3d82) Replaced midpoint integration of free bodies with [gyroscopic derivatives](https://mujoco.readthedocs.io/en/stable/computation/index.html#gefreebody) in the `implicitfast` [integrator](https://mujoco.readthedocs.io/en/stable/computation/index.html#geintegrators): the bias-force derivative of every standalone free body is applied via a local unsymmetric solve of its decoupled block, making `implicitfast` identical to `implicit` for such bodies. Unlike midpoint integration, which required vacuum and no constraints, this applies in all environments (contacts, fluid, constraints), and is compatible with discrete-time inverse dynamics. Spinning free bodies no longer gain energy, but tumbling motion is now mildly damped; models requiring long-horizon energy conservation of tumbling bodies in vacuum should use `RK4`. The [invdiscrete](https://mujoco.readthedocs.io/en/stable/XMLreference.html#option-flag-invdiscrete) flag no longer has any effect on forward dynamics.

4. [5618666a](https://github.com/google-deepmind/mujoco/commit/5618666a) Added [body/simple](https://mujoco.readthedocs.io/en/stable/XMLreference.html#body-simple) attribute ("false"/"auto") to disable the *simple body* mass matrix optimization. This is useful for domain randomization, where model parameters may change post-compilation.

5. [14c0b0c9](https://github.com/google-deepmind/mujoco/commit/14c0b0c9) [mj_setConst](https://mujoco.readthedocs.io/en/stable/APIreference/APIfunctions.html#mj-setconst) now recomputes the `mjModel.{body,geom,site}_sameframe` flags, to account for changes in body/geom/site frames after compilation.

6. [2444defc](https://github.com/google-deepmind/mujoco/commit/2444defc) Added support for [multiccd](https://mujoco.readthedocs.io/en/stable/computation/index.html#comulticcd) with arbitrarily large meshes.

### Added

- 🎨 **Redesigned interface.** Open WebUI has been visually rebuilt from the ground up. All aspects of the User Interface, from the chat view to the admin panel. Now with a narrower conversation column, lighter typography, tidier spacing, consistent menus and dropdowns, clearly outlined text boxes, and settings rearranged.

- 🤖 **Sub-agents.** Administrators can now enable sub-agents, which let a model hand parts of a task to background helper agents that run their own tool-driven conversations and report results back into the chat, tuned through new "ENABLE_SUBAGENTS", concurrency, iteration, and system-prompt settings. [Commit](https://github.com/open-webui/open-webui/commit/7088d245bb45fc69c0b22748563b9f3c6f0daa73), [Commit](https://github.com/open-webui/open-webui/commit/2f37e853d1259a901f736a823bad29dcc2c3b130), [Commit](https://github.com/open-webui/open-webui/commit/959558fd82eb2a3c980231acd500b73ba4b698b3), [Commit](https://github.com/open-webui/open-webui/commit/3005b7bc71fcbd5abc6e73c3e4caa4ea781cdb76)
- 📂 **Folder pages.** Opening a folder now takes you to its own page, where its chats load a page at a time, can be sorted by title or last updated, and you can start a new chat straight from the folder. [Commit](https://github.com/open-webui/open-webui/commit/409fb39717be9ab7becd9e8c01801a08c5bae318)
- ⏲️ **Chat timers.** The assistant can now set a timer that brings a prompt back into the conversation later, after a delay or at a set time, and can drop it automatically if you read the chat or reply before it fires. [Commit](https://github.com/open-webui/open-webui/commit/b23ddeb2800098c6352203ec8fbe9fca40ba415c)
- 🔔 **Notification targets.** Notifications now have their own settings tab where you can send them to several webhook destinations, each picking which events it wants, from chats finishing or failing to channel messages and calendar alerts, with a test button and a choice between always notifying or only when you are away, and any webhook you already had is carried over for you.

- 🌎 **Share a chat with anyone holding the link.** A shared chat can now be set to Open so it opens without signing in, with visitors no longer bounced to the sign-in page on their way to it, which administrators must first allow through a new "Chats Open Sharing" permission that stays off by default, and such pages ask search engines not to index them. [Commit](https://github.com/open-webui/open-webui/commit/1f0dc90abe879a55f654f2333e29fb0f630831c7), [Commit](https://github.com/open-webui/open-webui/commit/0e0d08382ac0d05b1ad98c47e8a2e37df2a185bb)
- 🔖 **Chat variables.** A model's system prompt can now declare fields such as text boxes and dropdown lists that you fill in for a conversation, with the values saved alongside the chat and carried over when it is forked or cloned.

- 🗄️ **LDAP group synchronization.** Administrators can now map LDAP groups to Open WebUI groups from the authentication settings, with optional automatic creation of missing groups, so a user's group memberships are kept in step with the directory each time they sign in. [#27263](https://github.com/open-webui/open-webui/pull/27263), [#18015](https://github.com/open-webui/open-webui/issues/18015)
- 👥 **Restrict sharing with groups.** Admins can now stop resources from being shared with entire groups through a new "USER_PERMISSIONS_ACCESS_GRANTS_ALLOW_GROUPS" permission, which stays enabled by default so existing group sharing keeps working untouched.

- 🕗 **Local message timestamps.** Message timestamps now appear on hover in your device's local date and time format, with the full weekday and date shown in a tooltip. [Commit](https://github.com/open-webui/open-webui/commit/797293c74957bd79e42262d1dc0fd637a45d0357), [Commit](https://github.com/open-webui/open-webui/commit/f84dabe3d97ff701c097055023f28f3f2f7ebd07)
- 📇 **User variables.** You can now store your own values in account settings, such as your role or how you like answers written, and a model's system prompt can insert them wherever they are needed. [Commit](https://github.com/open-webui/open-webui/commit/bd5d7b2e879511882429075d804d9222956f4a1a), [Commit](https://github.com/open-webui/open-webui/commit/212eec408ca320edfa2271e604d10e14b6a9bc1a), [Commit](https://github.com/open-webui/open-webui/commit/793a43d9c48225925929eb312fe2b70d5914d1da)
- 🧺 **Automations that file their chats away.** An automation can now be pointed at one of your folders, from the dialog, the editor or by asking the assistant, so each run lands there instead of loose in your chat list, and the folder is cleared automatically if it is later deleted. [Commit](https://github.com/open-webui/open-webui/commit/f798d05586a140f1a6b51f1e51b2b2a63d079d45), [Commit](https://github.com/open-webui/open-webui/commit/bab71ed08b5af6f4a8ff2daa02792baae9edab03), [Commit](https://github.com/open-webui/open-webui/commit/db5c092299471444c356216d5ef39b382ba1aa1e)
- 🔵 **See what you have not read yet.** Folders in the sidebar now carry a count of chats with something new in them, a folder's own page marks unread chats with a dot, shows a spinner on any still generating, clears the dot as you open one, and keeps itself up to date as replies finish elsewhere, unread chats sort to the top of a folder, and you can mark a single chat unread again mark everything in a folder read, or mark every chat read at once from the sidebar.

## Migration

**Settings and credentials now live in a backend-managed store.**

Provider settings and credentials previously persisted in the webview's `localStorage`. In 0.8.4, Jan reads and writes them from a backend-managed store instead (secrets go to the OS keyring). Your existing settings and API keys are copied over automatically on first launch - no manual action is needed, and from this version on all new changes are saved to the backend store.

Your old `localStorage` data is **not deleted** - it's kept as a snapshot so you can downgrade to a pre-0.8.4 build and still have your previous settings. Any changes you make in 0.8.4+ live only in the backend store, so a downgrade sees the older snapshot, not your latest settings.

* fix(rag): repair embeddings, stop chat-model reloads, and parse more PDFs by @qnixsynapse in https://github.com/janhq/jan/pull/8360

* New features
  * Added a doc on defining custom derivative rules with the experimental
    hijax API (`hijax-custom-derivatives`), along with
    `jax.experimental.hijax` helpers for deriving `VJPHiPrimitive` autodiff
    rules from a `jvp` or `lin` rule: `linearize_from_jvp` with
    `apply_derived_linearization`, `vjp_fwd_from_jvp` with `transpose_jvp`,
    `vjp_fwd_from_lin` with `transpose_linearized`, and `jvp_from_lin`.
  * Added `jax.custom_remat` to the top-level `jax` namespace, for
    per-function control of rematerialization under the new `jax_remat3`
    implementation.
  * `jax.checkpoint_policies` is now a submodule rather than a namespace
    object (so `from jax.checkpoint_policies import ...` now works; attribute
    access is unchanged), and it additionally exposes the name-based policy
    classes `SaveOnlyTheseNames`, `SaveAnyNamesButThese`, and
    `SaveAndOffloadOnlyTheseNames`.
  * Added `jax.Inline` enum for specify inlining policies to
    `jax.jit`.

* Breaking changes
  * The deprecated module j`ax.cloud_tpu_init` was removed. This did nothing and

## New Pipelines

### Cosmos 3

[**Cosmos 3**](https://huggingface.co/docs/diffusers/main/api/pipelines/cosmos3) is NVIDIA's unified world foundation model (WFM) for Physical AI — a single omni-model built on a Mixture-of-Transformers (MoT) architecture that combines world generation, physical reasoning, and action generation, replacing the separate Predict, Reason, and Transfer models from earlier Cosmos releases. A single `Cosmos3OmniTransformer` runs a Qwen-style language model in parallel with a diffusion generation pathway, joined by a 3D multimodal RoPE. This release also lands video-to-video and action-conditioned generation, and a sound encoder.

- Docs: [https://huggingface.co/docs/diffusers/main/api/pipelines/cosmos3](https://huggingface.co/docs/diffusers/main/api/pipelines/cosmos3)

Thanks to @atharvajoshi10, @yzhautouskay, and @MaciejBalaNV for the contributions.

### Ideogram 4

[**Ideogram 4**](https://huggingface.co/docs/diffusers/main/api/pipelines/ideogram4) is a flow-matching text-to-image model that uses a multimodal text encoder and an asymmetric classifier-free guidance scheme: a dedicated `unconditional_transformer` produces the negative branch with zeroed text features, while the main `transformer` consumes the full packed text + image sequence. The pipeline ships with structured prompt upsampling and LoRA loading support.

### Breaking Changes:
- Relaxed Gymnasium version range (from `"gymnasium>=0.29.1,<1.3.0"` to `"gymnasium>=0.29.1,<2.0"`)
- `pandas` and `matplotlib` are no longer core dependencies; they are now optional and only required for loading results and plotting (moved to `stable-baselines3[extra]`).
- Moved `read_json` and `read_csv` helper functions to test files
- Raised `torch` minimum version from 2.3 to 2.8 to mitigate https://github.com/advisories/GHSA-887c-mr87-cxwp

### Bug Fixes:
- Fixed deprecated error Taxi-v3 from gymnasium v1.3.0 in tests

### [SB3-Contrib]
- Optimized tests (faster to run)
- Fixed dead link for `RecurrentPPO`.

### [RL Zoo]


### [SBX] (SB3 + Jax)

- Added support for `rollout_buffer_class` and `rollout_buffer_kwargs` arguments in `PPO` and `OnPolicyAlgorithmJax` constructors, as in Stable Baselines3. (@Trenza1ore)
- Updated Jax dependency
