What is pathfindR?

pathfindR dropped Java from its subnetwork search and rebuilt it in C++

pathfindR runs active-subnetwork-oriented pathway enrichment on gene expression results. Version 3.0.0 re-implemented the greedy, simulated-annealing and genetic search algorithms in R and C++ through Rcpp, removing the Java dependency the package had carried since its early releases, and renamed three exported functions in the process. The two patches since have been consolidation: 3.0.1 fixed signed integer overflow in the new C++ hash function flagged by gcc-UBSAN and clang-UBSAN on CRAN, and 3.0.2 repaired tests after a companion data package changed a dataset structure.

What is Resend?

Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.

Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.

pathfindR dropped Java from its subnetwork search and rebuilt it in C++

◆ Current state

pathfindR runs active-subnetwork-oriented pathway enrichment on gene expression results. Version 3.0.0 re-implemented the greedy, simulated-annealing and genetic search algorithms in R and C++ through Rcpp, removing the Java dependency the package had carried since its early releases, and renamed three exported functions in the process. The two patches since have been consolidation: 3.0.1 fixed signed integer overflow in the new C++ hash function flagged by gcc-UBSAN and clang-UBSAN on CRAN, and 3.0.2 repaired tests after a companion data package changed a dataset structure.

◆ Where it's heading

The dependency surface has been shrinking for two years and Java was the last heavy one. 2.4.0 removed magick, KEGGgraph and KEGGREST by moving KEGG visualization onto ggkegg; 2.7.0 pushed org.Hs.eg.db from Imports to Suggests under CRAN policy, with functions degrading to defaults when it is absent; 3.0.0 finished the job on the search engine itself. The corresponding cost is now visible in 3.0.1: owning the algorithms in C++ means owning their undefined-behaviour reports too.

◆ Prediction

Expect the near-term releases to keep hardening the Rcpp search code against sanitizer findings and to verify GA parity with the legacy JAR, since 3.0.0 claimed numerically identical results only for the greedy and simulated-annealing methods.

Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.

◆ Current state

Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.

◆ Where it's heading

Resend is treating agents as the next class of sending client and building the authorization and discovery plumbing they need before that traffic arrives. The progression is legible: authenticate third parties (OAuth), be callable (MCP), be installable per vendor (Codex, Claude), then be installable by standard. The Cancel Broadcast API is the first sign of the next phase — once non-human callers can schedule sends, the ability to revoke one programmatically stops being a convenience.

◆ Prediction

Authorization and discovery are covered and reversibility has now started; the remaining gap is what an agent is permitted to send in the first place, so scoped per-agent sending limits or approval gates before dispatch are the natural next piece.
