What is Prowler?

Prowler's assistant stopped explaining findings and started deciding what to do with them.

Prowler ships roughly weekly and the Lighthouse AI thread runs through nearly every release. In 5.35.0 the assistant gained write actions and a side panel; 5.37.0 gave it page-aware context and the full Prowler MCP toolbox, with MCP itself adding integrations, users and roles on both Cloud and self-hosted; 5.39.0 puts a Skills menu on every individual finding. Around that, the paid tier keeps absorbing organizational complexity — Compliance Watchlist, multi-domain SAML SSO, and now Azure management-group onboarding — while 5.37.1 was a pure hardening release that cut the API image's critical CVE count from 18 to 4.

What is RSelenium?

RSelenium's only release in eight years touched documentation and CI, nothing else.

1.7.10, published February 2026, contains documentation updates, a move from Travis CI to GitHub Actions, and CRAN note fixes — no functional change at all, and it is the first release since September 2018. The releases before it are equally quiet: a dummy argument in `executeScript`, `phantom()` made defunct, and credential-exposure and driver-startup fixes. The last real capability change in the window is `rsDriver()` arriving in 1.6.4, which replaced the defunct `checkForServer` and `startServer` helpers.

Prowler's assistant stopped explaining findings and started deciding what to do with them.

◆ Current state

Prowler ships roughly weekly and the Lighthouse AI thread runs through nearly every release. In 5.35.0 the assistant gained write actions and a side panel; 5.37.0 gave it page-aware context and the full Prowler MCP toolbox, with MCP itself adding integrations, users and roles on both Cloud and self-hosted; 5.39.0 puts a Skills menu on every individual finding. Around that, the paid tier keeps absorbing organizational complexity — Compliance Watchlist, multi-domain SAML SSO, and now Azure management-group onboarding — while 5.37.1 was a pure hardening release that cut the API image's critical CVE count from 18 to 4.

◆ Where it's heading

Every Lighthouse release moves one step further from answering and closer to deciding. Read-only chat became actions, actions became context-aware, and the newest release attaches named skills to a single finding — including one that judges whether the finding is real and closes it out. The commercial line is drawn consistently: detection and the scanner stay open source, while the agentic layer and multi-tenant onboarding sit behind a Cloud subscription. Every write path is bound to the asking user's RBAC rather than a service identity, which is the same answer given each time the surface widens.

◆ Prediction

With triage decisions now automatable per finding, the unresolved question these entries raise is bulk: applying a skill across a finding group rather than one at a time, which is where Finding Groups and Systemic Scope already point. Expect the Azure onboarding pattern to be repeated for the remaining providers.

RSelenium's only release in eight years touched documentation and CI, nothing else.

◆ Current state

1.7.10, published February 2026, contains documentation updates, a move from Travis CI to GitHub Actions, and CRAN note fixes — no functional change at all, and it is the first release since September 2018. The releases before it are equally quiet: a dummy argument in `executeScript`, `phantom()` made defunct, and credential-exposure and driver-startup fixes. The last real capability change in the window is `rsDriver()` arriving in 1.6.4, which replaced the defunct `checkForServer` and `startServer` helpers.

◆ Where it's heading

This is a package being kept installable rather than developed. The 2016-2018 era did the architectural work — moving process management out to wdman, recommending Docker for running a Selenium server, retiring PhantomJS — and nothing since has revisited it. That leaves RSelenium sitting on the older WebDriver arrangement while the browser-automation landscape has moved on.

◆ Prediction

Further releases, if any, are likely to be CRAN-compliance rather than feature work; the entries give no indication of active development resuming.
