What is Merge?
Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.
What is websocket?
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.

Merge

Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
◆ Current state
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.
◆ Where it's heading
The through-line is that Merge is repositioning from data plumbing to the layer agents pass through. Each week adds either reach (more connectors, more tools per connector, more models) or control (guardrails, per-project policy, access configuration). This window is reach-and-efficiency: the GitHub connector expanded to 145 tools, Outlook payloads were cut substantially, and Gateway guardrails became configurable per project rather than per account.
◆ Prediction
Expect the per-project granularity applied to guardrails to spread to the rest of Gateway's controls, and the connector catalog to keep absorbing hosted third-party MCP servers the way Axiom was added.

0.0INFRA · APIS
A stable WebSocket client for R whose recent releases are almost entirely toolchain survival.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
