kreuzberg-dev/kreuzberg v4.0.0-rc.9 on GitHub

[4.0.0-rc.9] - 2025-12-15

PDFIUM_STATIC_LIB_PATH environment variable for custom static library paths (build.rs)
- Enables Docker builds with pdfium compiled from source
- Allows users to specify exact location of libpdfium.a for static linking
- Validates path existence and library presence with clear error messages
- Enables fully static binaries for minimal Docker images (FROM scratch)
- Platform-specific system library linking (pthread, dl on Linux)

Java: Maven publish now bundles native libraries (including Windows DLLs)
- Fixed Maven Central publish step to stage java-natives-* into the JAR and fail early if missing
Node: npm optional native packages now contain the .node binary
- Fixed packaging to copy the built .node into each @kreuzberg/node-<rid> platform package before publish
- Added a publish-time guard to fail if any platform package is missing its .node file
WASM: Node.js runtime no longer crashes with self is not defined
- Made wasm-bindgen-rayon thread pool support opt-in and removed it from default Node-target WASM builds
- Fixed Node.js WASM initialization to import the wasm-pack glue from pkg/kreuzberg_wasm.js
PDFium static linking (pdf-static feature) (build.rs)
- Fixed link_statically() to correctly search for static library (libpdfium.a) instead of dynamic library (.dylib/.so)
- Added macOS fallback to dynamic linking when static library unavailable (bblanchon/pdfium-binaries only provides dynamic libraries)
- Improved error messages explaining that bblanchon/pdfium-binaries doesn't provide static archives
- Added clear guidance for users needing static linking: build PDFium yourself, use PDFIUM_STATIC_LIB_PATH, or use alternative features
- Prevents build failures with helpful warnings on macOS, actionable errors on Linux
