What's Changed
Packaging
  • Update pydantic-core from 2.10.1 to 2.14.1, significant changes from these updates are described below, full changelog here
  • Update to pyright==1.1.335 by @​Viicos in #​8075
New Features
Changes
  • Significant Change: replace ultra_strict with new smart union implementation, the way unions are validated has changed significantly to improve performance and correctness, we have worked hard to absolutely minimise the number of cases where behaviour has changed, see the PR for details - by @​davidhewitt in pydantic/pydantic-core#867
  • Add support for instance method reassignment when extra='allow' by @​sydney-runkle in #​7683
  • Support JSON schema generation for Enum types with no cases by @​sydney-runkle in #​7927
  • Warn if a class inherits from Generic before BaseModel by @​alexmojaki in #​7891

Release v5.19.0

New Model additions

EmbeddingGemma2
image

EmbeddingGemma 2 is a multimodal embedding model from Google built on the Gemma 4 architecture. It encodes text, images, audio, and video, individually or combined in one input, into a shared 768-dimensional vector space for cross-modal retrieval, semantic similarity, clustering, and classification. It uses Matryoshka Representation Learning, so embeddings can be truncated to 512, 256, or 128 dimensions. It also offers configurable visual and video token budgets, and unused vision or audio towers can be disabled at load time to save memory.

Breaking changes

All MoE models whose routers compute logits now return them when output_router_logits=True, following the Qwen3-MoE pattern (a router_logits recorder on the base model, MoeModelOutputWithPast from the backbone, and a MoE causal LM output from the head), so code that relied on the previous outputs or their absence should read the router logits from these output classes.

Owlv2ForObjectDetection.embed_image_query now selects the query box with the highest objectness score, as in the original OWLv2 notebook, instead of the OWL-ViT heuristic, so image-guided query embeddings and detections may differ from earlier releases.

The "paged|" prefix for SDPA and flash attention implementations is deprecated, so users should set the regular attention implementation (e.g. sdpa or flash_attention_2) for continuous batching instead of paged|sdpa or paged|flash_attention_2.

The regular flash and SDPA attention functions (flash_attention.py, sdpa_attention.py) now support continuous batching directly, and "paged|..." implementations for these are redirected to them, while eager still requires the "paged|eager" prefix.

In continuous batching, the cache update for the index-based and block-table paths is now fused into a single call, which slightly changes the cache update function's behavior and affects any custom code that calls the separate update paths.

Continuous batching internals changed in preparation for removing "paged": `max

Parallelization

Expert parallelism gains a token-dispatch implementation, selected via the new ep_dispatch_experts plan rule and now the default for Qwen3 MoE and Mellum, which removes the requirement that EP size equal TP size. The Trainer was also adapted to work with expert parallelism, and the docs now note that PEFT adapters support tensor parallelism. A CI-related fix for pipeline-parallel chart2table inference was also included.

Cache

This release fixes quantized cache handling: generate no longer mutates the user's cache_config, and QuantizedLayer.reorder_cache is repaired. It also adds per-layer cache configuration, so DynamicCache and StaticCache initialize each layer from its own config (sliding window, attention chunk size, conv states, and attention head counts) to better support heterogeneous models. Separately, the deprecation cycle on mask and cache
