tidymodels' resampling package is retiring its old splitters for sliding windows.
A side-by-side editorial comparison of Docling and parsnip — release velocity, themes, recent moves, and the top alternatives to consider.
Docling keeps widening the funnel: every release adds another format the parser can swallow.
Docling ships roughly weekly, and the shape of each release is consistent — one or two new input formats or model paths, then a dense list of parser corrections for DOCX, ODF, PDF and PPTX. The latest window adds Outlook .msg with optional attachment listing, an EBCDIC backend, VLM grounding output from Unlimited-OCR, and OpenAI logprobs exposed as generated tokens. Underneath, the OCR layer was restructured into a layout-driven pipeline with configurable modes and a RapidOCR refactor that resolves all PP-OCR languages by version and backbone.
parsnip added a whole new regression type, then wired R models to JAX and PyTorch
The package is expanding what tidymodels can express. Version 1.5.0 introduced ordinal_reg() as a new model type with three engines and its own link parameters, and added xgboost and qrnn engines for quantile regression. Version 1.6.0 followed with a keras3 engine for four model types, reaching Keras v3's TensorFlow, JAX and PyTorch backends. Around those, releases have been tuning-parameter range adjustments and engine-specific fixes.

Two things are being built at once. The conversion surface keeps broadening toward whatever a document actually arrives as — email, mainframe encodings, scanned pages, audio via Whisper — while the service datamodel grows the knobs a hosted pipeline needs: chunking options and targets, PDF heading-level inference, batch connector sources, configurable stage shutdown timeouts. The steady drip of DOCX and ODF reading-order fixes says fidelity, not throughput, is where the hard problems still are.
Expect the format list to keep extending and the VLM and OCR paths to gain more configurability, with reading-order and list-numbering corrections continuing at the same rate. The agent-skills addition suggests more packaging for agent callers, though the entries show only a first step.

Growth is happening on two axes: new modelling tasks that previously had no unified interface, and new engines behind tasks that already did. Both push in the same direction - a modeller specifies the model once and swaps the computational backend underneath, which is the whole premise parsnip is built on. The defunct surv_reg() shows old spellings being retired as that surface settles.
Expect further engines behind ordinal_reg() and quantile regression now that both have a home, and continued retirement of deprecated function names. The keras3 engine's multi-backend design is the obvious candidate to spread to more model types.
