What is btm?

BTM has shipped nothing but compiler and integration compliance since 2020

BTM is an R binding to the Biterm Topic Model, aimed at short texts where standard LDA struggles. Its algorithmic surface has not changed in the visible history. Releases since 0.3.3 consist of a fedora-clang self-assignment fix, a terms.data.frame adjustment for compatibility with hardhat's assumptions, clang readability fixes, removal of the C++11 requirement, and documentation NOTEs about itemize.

What is Docling?

Docling keeps swallowing new formats, and now the parsing engines behind them are swappable.

Docling releases every three to four days, alternating feature drops with tight fix releases. The current one is purely corrective: DOCX headings detected by outline level when the style is not literally named Heading, Markdown tables keeping their last cell without a trailing pipe, and the service client serializing engine options in full. Format coverage now spans PDF, Office, ODF, HTML, JATS, email, audio and video.

◆ Current state

BTM is an R binding to the Biterm Topic Model, aimed at short texts where standard LDA struggles. Its algorithmic surface has not changed in the visible history. Releases since 0.3.3 consist of a fedora-clang self-assignment fix, a terms.data.frame adjustment for compatibility with hardhat's assumptions, clang readability fixes, removal of the C++11 requirement, and documentation NOTEs about itemize.

◆ Where it's heading

The package is finished in the sense that matters: the model works and the maintainer keeps it compiling. What movement there is comes from outside — a compiler flag, a CRAN check, another package's expectation about what stats::terms returns. It moves in lockstep with the rest of the bnosac NLP set, which received the same C++11 and packaging cleanups within a day of this one.

◆ Prediction

Nothing in the history points at model or interface work, so expect the next release whenever a CRAN check or toolchain change forces one across the sibling packages.

Docling keeps swallowing new formats, and now the parsing engines behind them are swappable.

◆ Current state

Docling releases every three to four days, alternating feature drops with tight fix releases. The current one is purely corrective: DOCX headings detected by outline level when the style is not literally named Heading, Markdown tables keeping their last cell without a trailing pipe, and the service client serializing engine options in full. Format coverage now spans PDF, Office, ODF, HTML, JATS, email, audio and video.

◆ Where it's heading

The engine layer is where the interesting movement is. Docling is shifting from one opinionated pipeline to a set of interchangeable layout, table and OCR backends the caller picks per run, which turns the library into a harness for models rather than a fixed parser. A second thread: the project shipped agent skills for itself in v2.118.0 and a separate docling-client package in v2.120.0, both pointing at being consumed programmatically rather than only imported. The structural-inference work — heading levels from font weight, now from DOCX outline levels — shows the parser learning to read documents that never declared their own structure.

◆ Prediction

Expect the engine-selection surface to keep widening, with OCR joining layout and table structure as a CLI-selectable backend. The steady stream of format-specific crash fixes suggests coverage is outrunning hardening, so more of these short corrective releases are likely between feature drops.
