kreuzberg-dev/kreuzberg v4.5.4 on GitHub

[4.5.4] - 2026-03-23

PDF image extraction panic on mismatched buffer lengths (#552): Replaced assert! with graceful error handling. Malformed PDF images are now skipped instead of panicking. Regression from v4.5.0.
pdf feature compilation without layout-detection (#550): config.layout reference gated behind #[cfg(feature = "layout-detection")].
WASM module resolution in Supabase/Deno edge functions (#551): Added explicit package.json exports and Deno detection in wasm-loader.
zip dependency pinned below 7.4: Avoids let-chain build failures on some stable Rust toolchains (#549).
Vendored HWP text extraction: Replaced external hwpers crate with vendored subset (~1,650 lines). Eliminates zip 2.x transitive dependency that caused WASM/CI build failures.
Ruby binding missing table_model field in LayoutDetectionConfig initializer.
Clippy/unused variable warnings in table recognition and pipeline modules.

prepend_heading_context chunking option: When true and chunker_type is Markdown, prepends the heading hierarchy path (e.g. # Title > ## Section) to each chunk's content string. Useful for RAG pipelines where chunks need self-contained structural context. Available across all 10 language bindings, CLI, and WASM. Includes fixture-driven e2e tests and documentation for all languages.
