distributions3 0.3.0 adds sample-based distributions and likelihood derivatives
A side-by-side editorial comparison of Delta Lake and sparklyr — release velocity, themes, recent moves, and the top alternatives to consider.
A 4.4.0 tag appears, but the feed carries only its release plumbing
The newest entry is the commit that tagged 4.4.0 — a version.sbt bump plus a local Maven overwrite setting needed for cross-Spark publishing, and it states outright that there are no runtime behaviour changes. The 4.4.0 release notes themselves have not reached this feed, so what the minor version actually contains is not readable here. Behind it sit two patch releases doing targeted correctness work: 3.3.3 on transaction log retention and Delta Sharing cache, 4.3.1 on Delta REST Catalog OAuth and S3A listing, interleaved with near-daily Databricks kernel build tags.
sparklyr now spends its releases absorbing dbplyr changes and feeding pysparklyr
sparklyr connects R to Spark, and almost nothing in this window originates inside the package. Releases restore compatibility after dbplyr changes its SQL generation, adapt to Spark 4.0 and to R 4.4's version-comparison changes, and convert functions into S3 methods so pysparklyr can supply its own implementations.

The project keeps two supported lines stable in parallel while the format work happens elsewhere, and the durable theme across these patches is metadata and log correctness — the failures that silently break time travel and CDF rather than throwing. The 4.4.0 prep notes one thing worth watching: artifacts are now published across Spark 4.0, 4.1 and 4.2 stages, so the cross-Spark support matrix is widening even as the release content stays out of view.
The 4.4.0 release notes should follow this tag and reveal what the minor version carries; until they do the entries support no read on its direction. The unresolved delta-iceberg artifact gap on the 3.3 line still has no follow-up here.
sparklyr connects R to Spark, and almost nothing in this window originates inside the package. Releases restore compatibility after dbplyr changes its SQL generation, adapt to Spark 4.0 and to R 4.4's version-comparison changes, and convert functions into S3 methods so pysparklyr can supply its own implementations.
Two dependencies set the agenda. dbplyr repeatedly changes identifier quoting and lazy-table internals, and each change costs sparklyr a release. Meanwhile the package is being hollowed into a backend: ml_fit(), spark_apply(), spark_write_delta() and now tune_grid_spark() exist as methods so that pysparklyr, the Databricks Connect path, can override them. Dependency removal - tibble, rappdirs, digest - runs alongside as the package slims down.
Expect the next releases to continue tracking dbplyr and Spark versions, and more functions to be converted to methods as functionality shifts toward pysparklyr; new capability arriving in sparklyr itself looks unlikely.
