mlr3fselect vs rvest: at a glance
What is mlr3fselect?
mlr3fselect turned feature selection into an asynchronous, distributable job
mlr3fselect runs feature selection for mlr3. The defining change in this window is 1.4.0, which introduced FSelectorAsync and the asynchronous instance classes, letting searches run without a synchronous batch loop. Around it sit ensemble feature selection work — fastVoteR ranking, embedded ensemble selection, result combination — and performance work on objective evaluation.
What is rvest?
rvest grew a real browser, turning a static scraper into a dynamic one.
rvest is the tidyverse's HTML scraping package. The 1.0.0 line rebuilt table parsing to mimic how browsers actually read tables, and 1.0.4 added read_html_live(), which drives a headless browser so JavaScript-rendered pages can be scraped at all. 1.0.5 is consolidation on that newer path.

mlr3fselect turned feature selection into an asynchronous, distributable job
◆ Current state
mlr3fselect runs feature selection for mlr3. The defining change in this window is 1.4.0, which introduced FSelectorAsync and the asynchronous instance classes, letting searches run without a synchronous batch loop. Around it sit ensemble feature selection work — fastVoteR ranking, embedded ensemble selection, result combination — and performance work on objective evaluation.
◆ Where it's heading
Two threads run in parallel: scaling the search itself through async execution and the rush backend, and making ensemble selection results easier to analyse via Pareto fronts, knee points and now removal of empty result rows. The rush backward-compatibility shim was dropped in 1.6.0, so the async path is now the assumed one.
◆ Prediction
Expect the ensemble result API to keep gaining analysis helpers, with async execution treated as the default rather than an option.

0.0ANALYTICS
rvest grew a real browser, turning a static scraper into a dynamic one.
◆ Current state
rvest is the tidyverse's HTML scraping package. The 1.0.0 line rebuilt table parsing to mimic how browsers actually read tables, and 1.0.4 added read_html_live(), which drives a headless browser so JavaScript-rendered pages can be scraped at all. 1.0.5 is consolidation on that newer path.
◆ Where it's heading
The package has split into two modes: fast static parsing for ordinary documents, and a live browser session for client-rendered ones. Recent effort concentrates on hardening the live path, where page navigation and interaction bugs surface that never existed in static parsing.
◆ Prediction
Expect further fixes and documentation around read_html_live() as more scraping targets move rendering to the client.
