What is rpymat?

After three dormant years, rpymat returned to fix the OpenMP crash that breaks R and conda together

rpymat manages an isolated conda-based Python environment for R packages, providing a reproducible bridge without touching the user's system Python. It released steadily through 2022-2023 and then went quiet for nearly three years. 0.1.9 in May 2026 is the first release since, and it addresses a specific and long-standing failure mode.

What is timbr?

Three years dormant, timbr returns with dplyr verbs that finally respect tree structure

timbr provides a 'forest' class for nested tree data in R, letting users navigate parent/child relationships with tidyverse-style verbs. After its last release in May 2023, the package sat untouched for over three years before 0.3.0 landed in July 2026. That release is dominated by correctness work on the structural invariants that everything else depends on.

After three dormant years, rpymat returned to fix the OpenMP crash that breaks R and conda together

◆ Current state

rpymat manages an isolated conda-based Python environment for R packages, providing a reproducible bridge without touching the user's system Python. It released steadily through 2022-2023 and then went quiet for nearly three years. 0.1.9 in May 2026 is the first release since, and it addresses a specific and long-standing failure mode.

◆ Where it's heading

The work is about surviving the seams between two runtimes. 0.1.9 addresses OpenMP double-initialization — the error users hit when R's OpenMP and conda's disagree — by setting KMP_DUPLICATE_LIB_OK as a compromise, and adds fix_omp_conflict() to symlink over conda's built-in version as the recommended real fix. The caveat is stated plainly: users must re-run it whenever R is updated, and the ABI versions must match. Earlier releases followed the same pattern, with 0.1.2 fixing segfaults from incompatible BLAS between numpy and R.

◆ Prediction

The recurring theme across releases is native library conflicts between the R and conda stacks, so further releases are likely to keep patching that surface as Python versions move. The three-year gap makes cadence unpredictable.

Three years dormant, timbr returns with dplyr verbs that finally respect tree structure

◆ Current state

timbr provides a 'forest' class for nested tree data in R, letting users navigate parent/child relationships with tidyverse-style verbs. After its last release in May 2023, the package sat untouched for over three years before 0.3.0 landed in July 2026. That release is dominated by correctness work on the structural invariants that everything else depends on.

◆ Where it's heading

The arc is from a working prototype toward a class that behaves correctly under the full dplyr surface. 0.3.0 implements relocate(), rows_patch() and rows_update() for forests and makes select() always preserve the internal node column, closing the gaps where a standard verb would silently break the tree. The deprecation of map_forest() in favour of traverse(), begun in 0.2.2, is now complete.

◆ Prediction

With the verb coverage gaps closed and the long deprecation cycle finished, the next release is likely to extend dplyr method coverage further rather than change the forest model. The entries do not indicate what prompted the three-year gap, so the sustainability of this cadence is unclear.
