What is DataSpaceR?

DataSpaceR's 1.0.0 rebuilt its query API and opened up HIV antibody sequence data.

The R client for the CAVD DataSpace reached 1.0.0 in July 2026 after five years of small fixes. The release removed the mAb grid filtering and view methods in favour of filtering an availableMabs object with data.table syntax, applied that pattern to every query method, and added a class for querying DAASH, the Database of Annotated Antibody Sequences for HIV-1. The August patch restored the LANL monoclonal-antibody metadata requests and batched BCR sequence queries.

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.

2.5

DataSpaceR's 1.0.0 rebuilt its query API and opened up HIV antibody sequence data.

◆ Current state

The R client for the CAVD DataSpace reached 1.0.0 in July 2026 after five years of small fixes. The release removed the mAb grid filtering and view methods in favour of filtering an availableMabs object with data.table syntax, applied that pattern to every query method, and added a class for querying DAASH, the Database of Annotated Antibody Sequences for HIV-1. The August patch restored the LANL monoclonal-antibody metadata requests and batched BCR sequence queries.

◆ Where it's heading

The package is converging on one query idiom — build a filtered object, then fetch — instead of per-domain grid methods, and each class now accepts multiple studies or antibodies rather than one. The 1.0.1 patch suggests the rewrite dropped functionality that users noticed, and it was put back rather than redesigned.

◆ Prediction

With DAASH access in place and the query surface unified, the next work is most likely more sequence-domain coverage and follow-up fixes to the batched query paths introduced in 1.0.1.

0.0

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.
