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 Agent Handler catalog now carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy. Gateway has been accumulating model coverage, routing controls and guardrails over the same period.
What is pkgbuild?
A package whose release calendar is written by whoever ships the next Rtools.
pkgbuild is the layer devtools and pak use to run R CMD build and R CMD INSTALL, and most of what it does is know where the compiler is. Six of its last eight releases are about Rtools: supporting Rtools43, 44 and 45, finding installations that did not come from an installer, reading the Windows registry correctly again, and handling aarch64 Windows when the expected environment variable is unset. The feature surface is a handful of Config/build/* DESCRIPTION options for packages with unusual build needs.

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 Agent Handler catalog now carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy. 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.
pkgbuild
0.0INFRA · APIS
A package whose release calendar is written by whoever ships the next Rtools.
◆ Current state
pkgbuild is the layer devtools and pak use to run R CMD build and R CMD INSTALL, and most of what it does is know where the compiler is. Six of its last eight releases are about Rtools: supporting Rtools43, 44 and 45, finding installations that did not come from an installer, reading the Windows registry correctly again, and handling aarch64 Windows when the expected environment variable is unset. The feature surface is a handful of Config/build/* DESCRIPTION options for packages with unusual build needs.
◆ Where it's heading
This is maintenance defined entirely by other people's release schedules — R minor versions, Rtools versions, and the DESCRIPTION options downstream package authors ask for. The one structural change worth noting is that on R 4.3 and later the package stopped special-casing Windows and now tests for build tools by compiling a small package, the same way it always has on Unix. That is the direction: fewer platform branches, more probing.
◆ Prediction
Expect the next release to add support for whichever Rtools ships alongside the next R minor version, and expect the Windows registry lookups to keep shrinking as the compile-probe approach proves out.
