What is bayesplot?

bayesplot keeps widening its posterior-check catalogue while absorbing each ggplot2 break.

bayesplot supplies the plotting layer for Stan-adjacent Bayesian workflows: posterior predictive checks, MCMC diagnostics and LOO diagnostics. Releases through 2025 alternate between new plot families and keeping pace with ggplot2, which changed behavior twice in the visible window. Contributions increasingly arrive from outside the core Stan team.

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.

bayesplot keeps widening its posterior-check catalogue while absorbing each ggplot2 break.

◆ Current state

bayesplot supplies the plotting layer for Stan-adjacent Bayesian workflows: posterior predictive checks, MCMC diagnostics and LOO diagnostics. Releases through 2025 alternate between new plot families and keeping pace with ggplot2, which changed behavior twice in the visible window. Contributions increasingly arrive from outside the core Stan team.

◆ Where it's heading

Two forces drive the release line: expanding what can be checked visually, and absorbing upstream ggplot2 churn. The 1.13-1.14 pair shows the first, adding LOO-PIT ECDF plots, quantile dot plots and discrete-data handling across the stat family, while 1.12 and 1.15 are largely spent on ggplot2 3.6 and 4.0 compatibility. The recurring new-contributor lists suggest maintenance load is being spread rather than concentrated.

◆ Prediction

Discrete-data support has rolled out plot family by plot family across three releases; the next release most likely continues that sweep and finishes the ggplot2 v4 adaptation.

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.
