What is LangGraph?

LangGraph's real work is happening in the checkpoint layer, not the graph runtime

Almost the entire release stream is persistence work spread across four packages: langgraph, checkpoint, checkpoint-postgres and checkpoint-sqlite. The delta channel, the incremental checkpoint mechanism, has produced correctness fixes in every release from 1.2.6 through 1.2.10 and into checkpoint 4.2.0. New in this window are an opt-in omit_expired flag that skips expired rows on read, and a conformance suite that runs the same tests against both the Postgres and SQLite backends.

What is Docling?

Docling is turning a document parser into a general ingestion layer — video now included.

Docling ships a tight semantic-release train, roughly weekly, where each version pairs one or two format or pipeline features with a long tail of fidelity fixes. The fixes are the real product: reading order in docx lists, section headers and footers, ODF text after inline elements, PPTX shapes in visual order, dehyphenation of hard continuations. Alongside the library, a service layer is taking shape — chunking options and targets, PDF heading-level inference, and batch connector sources are all being exposed through the service API rather than only the Python interface.

LangGraph's real work is happening in the checkpoint layer, not the graph runtime

◆ Current state

Almost the entire release stream is persistence work spread across four packages: langgraph, checkpoint, checkpoint-postgres and checkpoint-sqlite. The delta channel, the incremental checkpoint mechanism, has produced correctness fixes in every release from 1.2.6 through 1.2.10 and into checkpoint 4.2.0. New in this window are an opt-in omit_expired flag that skips expired rows on read, and a conformance suite that runs the same tests against both the Postgres and SQLite backends.

◆ Where it's heading

The graph runtime itself looks settled; the money is going into making storage backends behave identically and into controlling how much state gets read back. A conformance suite is what you build once you have multiple backends quietly drifting apart, and running it across Postgres and SQLite together suggests that drift was real. The tracing API is the unsettled edge: TracePolicy was exposed on add_node, had tags dropped, was deleted and then reverted, all inside 1.2.10.

◆ Prediction

Expect the conformance suite to pull additional checkpoint backends under the same tests, and omit_expired to graduate from opt-in once its read semantics have been exercised. The TracePolicy churn suggests the tracing surface gets another pass before it stabilizes.

Docling is turning a document parser into a general ingestion layer — video now included.

◆ Current state

Docling ships a tight semantic-release train, roughly weekly, where each version pairs one or two format or pipeline features with a long tail of fidelity fixes. The fixes are the real product: reading order in docx lists, section headers and footers, ODF text after inline elements, PPTX shapes in visual order, dehyphenation of hard continuations. Alongside the library, a service layer is taking shape — chunking options and targets, PDF heading-level inference, and batch connector sources are all being exposed through the service API rather than only the Python interface.

◆ Where it's heading

Format coverage is expanding outward from PDF and Office into anything an enterprise has lying around: legacy binary Office formats, an EBCDIC backend for mainframe data, and video as a declared input format with ASR presets behind it. The model layer is broadening in parallel — RapidOCR refactored to resolve all PP-OCR languages, a layout-driven OCR pipeline with configurable modes, and VLM output now carrying OpenAI logprobs through to predictions. Packaging is being taken seriously too, with chart extraction lazy-loaded so the slim build needs no torch, and agent skills shipped for driving Docling directly.

◆ Prediction

With VideoPipeline declared and ASR presets in place, the next step is likely fleshing out what a video actually converts into — transcript segments tied to frames — rather than adding another document format.
