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 whirl?
whirl turned script logging into a standardized provenance artifact regulators can read.
A parallel R script runner that produces execution logs, aimed at regulated analysis environments. The 0.3.0 release added write_biocompute(), emitting logs as BioCompute Objects in standardized JSON, and simplified the approved-package check to a plain package@version vector. Since then the work has been about what the log can be trusted to contain: an environment_secrets option to keep secret variables out of it, direct versus indirect package usage distinguished and highlighted against the approved list, and the same approval check extended to Python packages.

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
whirl turned script logging into a standardized provenance artifact regulators can read.
◆ Current state
A parallel R script runner that produces execution logs, aimed at regulated analysis environments. The 0.3.0 release added write_biocompute(), emitting logs as BioCompute Objects in standardized JSON, and simplified the approved-package check to a plain package@version vector. Since then the work has been about what the log can be trusted to contain: an environment_secrets option to keep secret variables out of it, direct versus indirect package usage distinguished and highlighted against the approved list, and the same approval check extended to Python packages.
◆ Where it's heading
The through-line is the log as evidence rather than as debugging output. Every recent addition either widens what the log proves — which packages were really used, in which language, against which approved list — or narrows what it must not leak. Setting options only through an explicit with_options argument to run() and getting renv library paths right for Quarto both point the same way: reproducible, auditable child sessions with nothing implicit.
◆ Prediction
Expect the approved-package and provenance machinery to keep expanding across languages and environments, since Python approval checks followed the R ones and both feed the same log.
