Delta Lake vs mapsf: at a glance
What is Delta Lake?
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.
What is mapsf?
Thematic mapping in base R that finally got a theming system, then spent two years polishing legends.
mapsf produces thematic maps on R's base graphics device — choropleths, proportional symbols, typology maps, rasters, and their combinations, with legends, scale bars, north arrows, and insets as composable elements. Version 1.0.0 was the structural release, introducing a theming system that deprecated eight scattered styling arguments and adding mf_png() and mf_svg() export helpers plus alpha transparency across map types. The 1.1.x and 1.2.x line since then has been steady refinement: background and extent control on the drawing functions, decimal and thousands-separator control in legends, and label placement arguments.

A 4.4.0 tag appears, but the feed carries only its release plumbing
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
mapsf
0.0ANALYTICS
Thematic mapping in base R that finally got a theming system, then spent two years polishing legends.
◆ Current state
mapsf produces thematic maps on R's base graphics device — choropleths, proportional symbols, typology maps, rasters, and their combinations, with legends, scale bars, north arrows, and insets as composable elements. Version 1.0.0 was the structural release, introducing a theming system that deprecated eight scattered styling arguments and adding mf_png() and mf_svg() export helpers plus alpha transparency across map types. The 1.1.x and 1.2.x line since then has been steady refinement: background and extent control on the drawing functions, decimal and thousands-separator control in legends, and label placement arguments.
◆ Where it's heading
The package has been consolidating control into fewer, more consistent places. Legend handling moved out to the maplegend package in 0.8.0 and the per-element mf_legend_* functions were deprecated in favor of arguments on the map calls themselves; theming replaced ad-hoc style arguments in 1.0.0; and recent releases keep propagating the same argument vocabulary — bg, extent, leg_val_rnd, leg_val_dec, leg_val_big — across every function that should accept it. Determinism is a visible concern too, with 1.2.1 fixing a seed so mf_distr() point positions stop moving between runs.
◆ Prediction
The recent releases are almost entirely argument-parity work across existing functions, so expect that to continue until the vocabulary is uniform rather than any new map type appearing.
