What is gMCPLite?

gMCPLite exists to be gMCP without Java, and its releases guard that boundary rather than extend it.

gMCPLite is a fork of gMCP with the Java dependency removed and `hGraph()` ported over from gsDesign, giving R users graphical multiple comparison procedures and their visualisation without a JVM. Since that fork, no release has added a statistical capability. The visible history is compatibility work: ggplot2 3.5.0 argument naming, a cairo device for Unicode in examples, testthat 3.3.0 snapshot requirements, and a selective port of an upstream confidence-interval fix.

What is S7?

S7 has stopped adding surface and started proving it holds up against R itself.

S7 is R's third-generation object system, built to unify the S3 and S4 lineages rather than add a fourth. The design work landed in 0.2.0, which reworked the default constructor, extended base-class coverage, and added a backward-compatibility shim so `@` property access works on R older than 4.3. Everything since has been maintenance: property setters gained a `check` escape hatch, and two consecutive releases exist mainly to keep the package compiling against R-devel 4.6.

gMCPLite exists to be gMCP without Java, and its releases guard that boundary rather than extend it.

◆ Current state

gMCPLite is a fork of gMCP with the Java dependency removed and `hGraph()` ported over from gsDesign, giving R users graphical multiple comparison procedures and their visualisation without a JVM. Since that fork, no release has added a statistical capability. The visible history is compatibility work: ggplot2 3.5.0 argument naming, a cairo device for Unicode in examples, testthat 3.3.0 snapshot requirements, and a selective port of an upstream confidence-interval fix.

◆ Where it's heading

This is a package with a fixed job. The maintainers track two moving targets — the upstream gMCP it forked from, and the R graphics and testing stack underneath it — and pull across only what is needed. The addition of vdiffr visual regression tests for `hGraph()` is the most substantive recent change and fits the same posture: the plots are the deliverable, so pin them against accidental drift rather than redesign them.

◆ Prediction

Expect the pattern to continue — compatibility releases driven by ggplot2, testthat and pkgdown changes, with any statistical content arriving only as a selective port from upstream gMCP.

S7 has stopped adding surface and started proving it holds up against R itself.

◆ Current state

S7 is R's third-generation object system, built to unify the S3 and S4 lineages rather than add a fourth. The design work landed in 0.2.0, which reworked the default constructor, extended base-class coverage, and added a backward-compatibility shim so `@` property access works on R older than 4.3. Everything since has been maintenance: property setters gained a `check` escape hatch, and two consecutive releases exist mainly to keep the package compiling against R-devel 4.6.

◆ Where it's heading

The changelog is thinning by design — 0.1.0 was a months-long feature dump, 0.2.0 a coordinated architectural revision, 0.2.2 a single line about internal R-devel support. That shape usually means an API the maintainers consider settled, where the remaining work is tracking the host language rather than extending the system. The one recurring theme is validation cost: repeated releases have made validation less frequent, more targeted, or skippable outright.

◆ Prediction

Expect continued small releases pinned to R-devel changes rather than new class-system features, with any further movement most likely in the validation and property-setter path that the last two feature changes both touched.
