Resend
Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.
A side-by-side editorial comparison of Prowler and websocket — release velocity, themes, recent moves, and the top alternatives to consider.
Prowler's assistant decides what to do with findings; the patches keep the scanner honest
Prowler is shipping a minor release roughly weekly with patches filling the gaps. The agentic layer, Lighthouse, has moved from explaining findings to acting on them, with named skills attached to individual findings and every write path bound to the asking user's RBAC. Alongside that, 5.39.1 fixes an install path that had been quietly broken: 5.38.0 declared a cryptography floor its own dependencies capped below, so pip install prowler silently resolved back to 5.37.1.
A stable WebSocket client for R whose recent releases are almost entirely toolchain survival.
websocket wraps WebSocket++ to give R a client with an event-callback interface. The functional work finished years ago; the top of the release history is compiler warnings, OpenSSL packaging, and Windows toolchain support. The one structural change in the window is the move from Rcpp and BH to cpp11.

Two tracks run in parallel and rarely overlap. The minor releases push the commercial agentic surface forward — triage skills, page context, the MCP tool set — while the patches defend the parts everyone uses: dependency resolution, container CVEs, and check correctness. That second track matters more than its version numbers suggest, because a security scanner reporting PASS when an API call failed is worse than one that errors. 5.39.1 fixes exactly that in the ECS task-definition checks, and makes the SES public-access check evaluate every identity policy rather than stopping at the first.
Expect the next minor to extend Lighthouse skills to groups of findings rather than one at a time, with patch releases continuing to absorb Trivy and base-image CVE churn.

Effort has shifted almost entirely to keeping the C++ layer building across compilers and platforms — silencing deprecation warnings, handling Windows systems without openssl.pc, adding UCRT support. That is what maintenance looks like for a package whose value is a stable binding rather than an evolving API, and the four-year gap between 1.4.1 and 1.4.4 fits it.
Future releases will most likely continue to be triggered by compiler or CRAN toolchain changes rather than by protocol or API work, following every release in this window.
