What is Rho?
Rho 0.5.4 adds a generic ACP backend so agents beyond Claude can plug in
Rho is an R IDE with an agentic layer whose feed is mostly release engineering. 0.5.3 let Claude sessions run without Rho's step and time caps, and 0.5.4 added a generic ACP backend so other agents can plug in, plus Node 24 and 26 install support. 0.5.6 and 0.5.7 followed within four days as CI-promoted candidates with no notes of their own.
What is Fulcrum?
Fulcrum ships Follow Mode to iOS and Android and tightens MCP sign-in.
Fulcrum, a field data collection platform, released Follow Mode on iOS and Android 2611.0.0, keeping the map centred on the collector, and Android now accepts a required GPS accuracy as fine as 0.1 m. The weekly web release redesigned the MCP authorization page to show the requesting client and organization, and fixed blank Report Builder PDFs and App MCP form validation. The Insights AI assistant opened to all customers in October.

5.0ANALYTICS
Rho 0.5.4 adds a generic ACP backend so agents beyond Claude can plug in
◆ Current state
Rho is an R IDE with an agentic layer whose feed is mostly release engineering. 0.5.3 let Claude sessions run without Rho's step and time caps, and 0.5.4 added a generic ACP backend so other agents can plug in, plus Node 24 and 26 install support. 0.5.6 and 0.5.7 followed within four days as CI-promoted candidates with no notes of their own.
◆ Where it's heading
The 0.5 line is moving from a Claude-specific agent bridge toward an agent-neutral one: a generic ACP backend, per-agent permission grants and packaged Skills. Distribution is also maturing, with npm registry installs now the documented path.
◆ Prediction
Expect a 0.5.x release that documents or tests specific ACP agents against the new backend, and more Skills packaged for analysis workflows.
Fulcrum
6.3ANALYTICS
Fulcrum ships Follow Mode to iOS and Android and tightens MCP sign-in.
◆ Current state
Fulcrum, a field data collection platform, released Follow Mode on iOS and Android 2611.0.0, keeping the map centred on the collector, and Android now accepts a required GPS accuracy as fine as 0.1 m. The weekly web release redesigned the MCP authorization page to show the requesting client and organization, and fixed blank Report Builder PDFs and App MCP form validation. The Insights AI assistant opened to all customers in October.
◆ Where it's heading
Two tracks continue: precision GPS for field crews, with external receivers and accuracy settings, and controlled access for outside AI assistants through the MCP server. Most releases are fixes on a weekly mobile and web cadence.
◆ Prediction
Expect the GPS integration to leave beta and the MCP server to move past alpha with OAuth as the default sign-in.
