What is rtflite?

rtflite stopped being an RTF writer and became the conversion layer for clinical table output.

rtflite generates the RTF tables clinical study reports are built from, a Python answer to the R tooling that has owned this niche. Over one dense month it grew a full export path: DOCX in 2.2.0, DOCX concatenation in 2.3.0, a configurable LibreOffice converter in 2.4.0, and HTML plus PDF in 2.5.0. The three releases since have been documentation, test infrastructure, and typing work — the feature push has stopped and consolidation has started.

What is vcr?

Added the HTTP client everyone moved to, then deleted a decade of its own public surface.

vcr records HTTP interactions to disk so R package tests can replay them without network access. Two releases define its current state. Version 1.6.0 added httr2 support alongside the existing httr and crul backends, following the R ecosystem's migration to httr2. Version 2.0 then removed a large amount of accumulated public surface — the logging functions, vcr_last_error(), the exported R6 classes including RequestHandler, Request, VcrResponse and HTTPInteractionList, and several configuration options that had stopped working or could not be implemented correctly.

rtflite stopped being an RTF writer and became the conversion layer for clinical table output.

◆ Current state

rtflite generates the RTF tables clinical study reports are built from, a Python answer to the R tooling that has owned this niche. Over one dense month it grew a full export path: DOCX in 2.2.0, DOCX concatenation in 2.3.0, a configurable LibreOffice converter in 2.4.0, and HTML plus PDF in 2.5.0. The three releases since have been documentation, test infrastructure, and typing work — the feature push has stopped and consolidation has started.

◆ Where it's heading

Every format addition routes through the same LibreOffice converter rather than a per-format implementation, and 2.4.0's breaking change made that converter an injectable object you can configure and reuse. That is the shape of a package expecting to run inside a pipeline that produces hundreds of tables, not one that converts a document at a time. The recent quiet — snapshot tests moved onto `pytest-r-snapshot`, docs migrated, pandas and pyarrow dropped from dev dependencies — reads as work to stay dependency-light while the surface stabilizes.

◆ Prediction

With the export matrix filled in and three consecutive infrastructure-only releases, the next substantive change is most likely on the input side — table construction and pagination — since `page_by` and `subline_by` are the only feature area still generating bug reports in these notes.

Added the HTTP client everyone moved to, then deleted a decade of its own public surface.

◆ Current state

vcr records HTTP interactions to disk so R package tests can replay them without network access. Two releases define its current state. Version 1.6.0 added httr2 support alongside the existing httr and crul backends, following the R ecosystem's migration to httr2. Version 2.0 then removed a large amount of accumulated public surface — the logging functions, vcr_last_error(), the exported R6 classes including RequestHandler, Request, VcrResponse and HTTPInteractionList, and several configuration options that had stopped working or could not be implemented correctly.

◆ Where it's heading

The package is consolidating after years of additive growth. The 2.0 removals are almost all things that were exported without needing to be, or options that promised behaviour the implementation could not guarantee — check_cassette_names() was deprecated precisely because it cannot be made correct. Cassette maintenance is being simplified too, with re_record_interval now the single mechanism for expiring recordings.

◆ Prediction

Expect the post-2.0 releases to be about migration support and fallout from the removed API, since the breaking list is long enough that reverse dependencies will surface problems. Async support for httr2 stays blocked until req_perform_parallel gains a mocking hook, which the entries note is upstream work.
