What is crosstalk?

crosstalk is frozen infrastructure: four releases in five years, mostly CRAN upkeep.

crosstalk provides the shared-selection and filtering layer that lets independent htmlwidgets communicate on a page without Shiny. Its visible history is four releases across five years, one of which made a substantive change and three of which were fixes. The most recent exists only to clear an R CMD check NOTE.

What is Delta Lake?

Delta Lake's public releases are patch work while Databricks kernel builds fill the feed.

Two kinds of entry dominate: numbered patch releases on the 3.3 and 4.3 lines, and near-daily Databricks kernel build tags that carry a single commit message each. The patch releases are targeted correctness work — a metadata cleanup that could delete transaction log files still needed to reconstruct versions inside the retention window, a Delta Sharing cache refresh that dropped deletion-vector URL mappings, an OAuth key-casing bug in the REST Catalog, and S3A fast-listing through FilterFileSystem wrappers. The 3.3.3 release also declines to publish delta-iceberg, leaving UniForm users on the prior patch.

0.0

crosstalk is frozen infrastructure: four releases in five years, mostly CRAN upkeep.

◆ Current state

crosstalk provides the shared-selection and filtering layer that lets independent htmlwidgets communicate on a page without Shiny. Its visible history is four releases across five years, one of which made a substantive change and three of which were fixes. The most recent exists only to clear an R CMD check NOTE.

◆ Where it's heading

The package is finished in the sense that matters: it does one thing, widget authors depend on it, and it changes when R or CRAN forces it to. The single directional move here is 1.2.0 dropping the bundled Bootstrap dependency so crosstalk stops imposing a CSS framework on the pages that embed it. Nothing since suggests further design work.

◆ Prediction

The next release is most likely another CRAN-compliance fix; the entries show no feature work in progress.

Delta Lake
ANALYTICS
5.0

Delta Lake's public releases are patch work while Databricks kernel builds fill the feed.

◆ Current state

Two kinds of entry dominate: numbered patch releases on the 3.3 and 4.3 lines, and near-daily Databricks kernel build tags that carry a single commit message each. The patch releases are targeted correctness work — a metadata cleanup that could delete transaction log files still needed to reconstruct versions inside the retention window, a Delta Sharing cache refresh that dropped deletion-vector URL mappings, an OAuth key-casing bug in the REST Catalog, and S3A fast-listing through FilterFileSystem wrappers. The 3.3.3 release also declines to publish delta-iceberg, leaving UniForm users on the prior patch.

◆ Where it's heading

The project is stabilising two supported lines in parallel rather than moving the format forward in these entries, and the recurring theme is metadata and log durability — the parts of Delta that silently break time travel and CDF when they are wrong. Kernel work continues in the build tags, most visibly treating _last_checkpoint as opaque JSON. The unpublished UniForm artifact is the one open thread with a stated follow-up plan.

◆ Prediction

A follow-up patch that restores the delta-iceberg artifact for the 3.3 line is the clearest next step; otherwise expect the kernel build cadence to continue between numbered releases.
