What is sps?

sps keeps sanding down sequential Poisson sampling rather than adding to it.

The package implements sequential Poisson sampling for survey design, covering inclusion probabilities, proportional allocation, replicate weights, and take-all strata. Recent releases are small and tightly scoped: a divisor method helper, an iterator that draws a sample one unit at a time, automatic selection of the replicate-weight parameter, and repeated performance work on inclusion probability calculation.

What is WPML?

WPML made machine translation the default, and its point releases keep chasing WordPress and page builders.

The shipping 4.9 line is compatibility work: WordPress 7.1 support with a security hardening pass in the newest release, PHP 8.5 compatibility and a smoother site-migration flow before that, and WordPress 7.0's iframe-based block editor before that. The 5.0 beta running in parallel is the larger move — a redesigned interface, a simplified translation engine, and automatic translation switched on by default for new sites.

sps keeps sanding down sequential Poisson sampling rather than adding to it.

◆ Current state

The package implements sequential Poisson sampling for survey design, covering inclusion probabilities, proportional allocation, replicate weights, and take-all strata. Recent releases are small and tightly scoped: a divisor method helper, an iterator that draws a sample one unit at a time, automatic selection of the replicate-weight parameter, and repeated performance work on inclusion probability calculation.

◆ Where it's heading

Development is consolidation rather than expansion. Most releases either speed up an existing routine or remove a decision the user previously had to make by hand, such as picking the smallest parameter that keeps replicate weights non-negative. Documentation and tooling get comparable attention to the algorithms, with a dedicated vignette on inclusion probabilities and a recent switch of test and documentation infrastructure. The API surface has been essentially stable across the window.

◆ Prediction

Expect continued small ergonomic and performance releases against the existing function set rather than new sampling designs, which is the pattern every release in this window follows.

6.3

WPML made machine translation the default, and its point releases keep chasing WordPress and page builders.

◆ Current state

The shipping 4.9 line is compatibility work: WordPress 7.1 support with a security hardening pass in the newest release, PHP 8.5 compatibility and a smoother site-migration flow before that, and WordPress 7.0's iframe-based block editor before that. The 5.0 beta running in parallel is the larger move — a redesigned interface, a simplified translation engine, and automatic translation switched on by default for new sites.

◆ Where it's heading

Two clocks again. The maintenance clock is dictated entirely by other people's releases: WordPress majors, PHP versions, Divi 5, Elementor. Enough of this feed is compatibility that it reads as the real cost of being a translation layer inside someone else's ecosystem. The product clock points one direction, toward automation — cost and time estimates before sending content, one-click recovery for stuck jobs, automatic detection of custom Elementor widgets, and now automatic translation as the starting state rather than an option. The 4.9.7 security hardening is worth noting alongside a beta in flight: the stable line still gets real attention.

◆ Prediction

Expect the 5.0 line to move from beta to production with the automatic-first defaults intact, followed by continued compatibility maintenance as WordPress core and major builders evolve.
