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 metR?
A meteorology ggplot2 extension where the netCDF reader became the main event
metR supplies meteorological and oceanographic tools for R: contour and streamline geoms, EOF decomposition, wave fitting, and ReadNetCDF() for getting gridded data in. Development has concentrated heavily on that reader. Version 0.18.0 added subsetting by dimension index, so the first or last ten timesteps can be read without knowing how many exist; 0.18.1 moved time parsing to the CFtime package; 0.18.2 added cdo operations through rcdo and reading across multiple files in parallel, and fixed a subsetting bug where nearest-gridpoint matching could return data outside the requested range entirely.

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.

◆ Current state
metR supplies meteorological and oceanographic tools for R: contour and streamline geoms, EOF decomposition, wave fitting, and ReadNetCDF() for getting gridded data in. Development has concentrated heavily on that reader. Version 0.18.0 added subsetting by dimension index, so the first or last ten timesteps can be read without knowing how many exist; 0.18.1 moved time parsing to the CFtime package; 0.18.2 added cdo operations through rcdo and reading across multiple files in parallel, and fixed a subsetting bug where nearest-gridpoint matching could return data outside the requested range entirely.
◆ Where it's heading
Two threads run through the releases. The first is tracking ggplot2, absorbing the linewidth aesthetic, the trans to transform rename and guide compatibility as each landed upstream. The second is narrowing scope while deepening the data path: GetSMNData() was made defunct as too specific for a general package, raster and gdal dependencies were removed, and the udunits2 dependency was dropped when it was orphaned, initially replaced by a homebrewed date parser and eventually by CFtime. The result is a package steadily shedding its own code in favour of specialised upstream libraries.
◆ Prediction
Expect further ReadNetCDF() work, since it has received features in four of the last five releases and the rcdo integration opens a large surface of operations to expose.
