A POMDP solver that quietly grew into a full reinforcement-learning toolkit.
A side-by-side editorial comparison of arulesCBA and Firecrawl — release velocity, themes, recent moves, and the top alternatives to consider.
arulesCBA is stable enough that its releases are mostly CRAN's idea.
arulesCBA builds classifiers from association rules — CBA, RCAR, and wrappers around the LUCS-KDD Java implementations. The algorithm set has not changed across any release in this window; the work is packaging, dependency tracking and edge cases. The most recent release fixes a rowSums bug in M1 pruning and a bug-report link flagged by CRAN.
Firecrawl stopped selling pages and started selling answers — now it is giving the corpus away.
Firecrawl has spent four months converting a scraping API into an answer-retrieval layer for agents. Question, Highlights and the excerpt-scoring rebuild of /search all trade full-page delivery for the specific lines that answer a query, each pitched on token cost rather than coverage. Alongside that it has started owning corpora outright — the Research Index now spans 3M+ arXiv papers and 41M+ life-sciences papers — and /monitor turns crawling into a subscribable event stream.

Development has settled into removing the reasons users file issues. Shipping the LUCS-KDD jars preinstalled in 1.2.3 eliminated a compilation failure, headless Java support in 1.2.4 made those algorithms usable on servers, and single-rule classifiers were made to work in 1.2.6. Each is a narrow fix, but together they close off the install-and-environment problems that make a Java-backed R package awkward to adopt.
Expect the next release to be triggered by an arules or Matrix API change rather than by new classifier work — that pattern accounts for most of this history, including a function rename forced by arules adding its own rules().

The centre of gravity is moving from generic crawl infrastructure to curated indexes with published benchmark numbers attached, and now to giving those indexes away. Every recent release argues the same point in a different register: the crawler should return the smallest correct thing, and Firecrawl should already have it indexed. Free access to Research Index converts a metered data product into a distribution channel for the paid scraping and monitoring endpoints around it.
Expect a third vertical index after AI/ML and life sciences — the pattern of a benchmark claim, daily refresh and API-plus-MCP-plus-CLI availability is now a repeatable template. Whether the free tier stays free once query volume lands is the open question the entries do not answer.
