What is hoardr?

A cache-directory helper that has shipped nothing but CRAN-triggered patches for seven years.

hoardr manages local cache directories for other R packages — where files go, how they are keyed, whether they exist. It underpins caching in several rOpenSci data clients. The last functional additions were in 2018; everything since is a patch issued because CRAN reported a test failure or the maintainer changed.

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.

0.0

A cache-directory helper that has shipped nothing but CRAN-triggered patches for seven years.

◆ Current state

hoardr manages local cache directories for other R packages — where files go, how they are keyed, whether they exist. It underpins caching in several rOpenSci data clients. The last functional additions were in 2018; everything since is a patch issued because CRAN reported a test failure or the maintainer changed.

◆ Where it's heading

This is infrastructure that has reached its final shape. Three of the last three releases were reactive: two responses to CRAN test-failure notifications, one to a maintainer handover. The single behavioural change in that stretch — forward slashes in paths on every operating system — is a consistency fix for downstream packages rather than a feature. Its release cadence is set by CRAN's checks, not by demand.

◆ Prediction

Expect the next release to be triggered by another CRAN check failure rather than by new functionality, matching every release since 2018.

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.
