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 fdacluster and Prowler — release velocity, themes, recent moves, and the top alternatives to consider.
Functional data clustering grew from one algorithm into a comparable suite
fdacluster clusters functional data while separating amplitude from phase variation, aligning curves as part of the clustering rather than before it. The algorithm set covers k-means, hierarchical clustering and DBSCAN, all producing a common caps result object so runs can be compared directly. Version 0.4.0 tightened the interface with is_domain_interval and transformation arguments describing the input data, added compatibility checking between incompatible option combinations, and split the L2 and normalized L2 distances into separate C++ classes to enforce that plain L2 cannot be combined with dilation or affine warping it is not invariant to.
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.

The trajectory runs from method implementation toward guardrails and portability. Early releases added capability; recent ones prevent misuse and reduce weight - dplyr, forcats, tidyr and purrr removed in 0.4.0, furrr swapped for future.apply - while 0.4.2 is entirely C++ correctness, replacing Armadillo's whole-object finiteness check with scalar std::isfinite and fixing an integer overflow in linear index computation that broke large datasets. Cadence is roughly one release a year.
Given that the last two releases were dependency reduction and numerical correctness rather than method work, expect the next to continue in that vein unless a new clustering algorithm is contributed.

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.
