 | ~b9354–b9437 | `vendor/cpp-httplib/` | Bumped to v0.46.0: adds `Client::set_no_proxy(std::vector<std::string>)` with full hostname-suffix and IPv4/IPv6 CIDR matching; `Server::ThreadPool` constructor is exception-safe (already in v0.45.0); `Client::set_proxy()` now disconnects the held socket immediately so a later proxy change cannot reuse the old TLS session. Compiled automatically, no project changes required |
 | ~b9354–b9437 | `common/arg.cpp` (additive flags) | New `--spec-draft-backend-sampling` / `--no-spec-draft-backend-sampling` (env `LLAMA_ARG_SPEC_DRAFT_BACKEND_SAMPLING`) and `--skip-download` (mapped to `common_params::skip_download`). Both default-on / default-off in a way that preserves current Java behaviour. Consider exposing as `ModelParameters.setSpecDraftBackendSampling(boolean)` and `setSkipDownload(boolean)` in a follow-up — tracked under Open TODOs |
 | ~b9354–b9437 | `ggml/src/ggml-cuda/common.cuh` | `GGML_CUDA_USE_PDL` gating tightened: for MSVC, now requires CTK ≥ 12.3 (was 11.8) due to a compiler bug in the older Windows CUDA toolchains. Project's only CUDA build is Linux (dockcross, CUDA 13.2) so the MSVC gate has no CI impact; Windows CI builds CPU-only |
+| ~b9437–b9442 | `src/llama-vocab.{h,cpp}` + `src/llama-arch.{h,cpp}` | New `LLAMA_VOCAB_PRE_TYPE_WHITESPACE = 53` and `llm_tokenizer_whitespace_session` (used by jina-v2-base-zh embeddings); new "whitespace" tokenizer_model routed as `LLAMA_VOCAB_TYPE_BPE`; new `LLM_KV_TOKENIZER_NORMALIZER_LOWERCASE` key (`tokenizer.ggml.normalizer.lowercase`) read into `llama_vocab::impl::normalizer_lowercase`; new public accessor `llama_vocab::get_normalizer_lowercase()`. All additive — existing tokenizers untouched; new whitespace + lowercase normalizer is consumed automatically when loading a GGUF that sets these vocabulary keys, no project source or Java API changes required |
+| ~b9437–b9442 | `src/llama.cpp` | `llama_prepare_model_devices()` iGPU collection now appends only the FIRST `GGML_BACKEND_DEVICE_TYPE_IGPU` device (prevents duplicate iGPU registration on multi-iGPU hosts). Behavioural fix, single-line caller in `jllama.cpp` unchanged, no project source changes required |
+| ~b9437–b9442 | `tools/ui/embed.cpp` + `tools/ui/src/...` (Svelte) | Webasset embedder tightened printf format specifiers (`%lu` &#x2192; `%zu` and `PRIx64`); UI settings split `custom` into `customJson` + `customCss`; runtime CSS injection via `<svelte:head>`. Project does not ship the upstream UI, no impact |
+| ~b9437–b9442 | `gguf-py/`, `conversion/` (Python) | New `_set_vocab_whitespace()` helper and `add_normalizer_lowercase()` GGUF writer for the new whitespace tokenizer + lowercase normalizer keys (mirrors the vocab additions above); jina-v2 Roberta-tokenizer path now branches to whitespace when `tokenizer.json` declares a `Whitespace` pre-tokenizer. Python-side only, no impact on the Java/JNI build |
