What is dockerfiler?

dockerfiler's 1.0.0 changes what its generated Dockerfiles actually contain.

After two years of small parameter additions, ThinkR shipped a 1.0.0 that changes the tool's output for every existing user. The vendored copy of renv is gone, generated images default to multi-arch rocker/r-ver running as a non-root rstudio user, and packages come from Posit Public Package Manager binaries instead of a source CRAN mirror.

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.

0.0

dockerfiler's 1.0.0 changes what its generated Dockerfiles actually contain.

◆ Current state

After two years of small parameter additions, ThinkR shipped a 1.0.0 that changes the tool's output for every existing user. The vendored copy of renv is gone, generated images default to multi-arch rocker/r-ver running as a non-root rstudio user, and packages come from Posit Public Package Manager binaries instead of a source CRAN mirror.

◆ Where it's heading

The package is being hardened rather than extended. Every user-supplied value that reaches a Dockerfile shell context is validated at function entry, and two long-standing code-injection paths — a crafted renv.lock version string and DCF continuation lines in DESCRIPTION fields — were closed after an internal audit. The new parameters point at production image builds: github_pat via BuildKit secret mounts, strict_install turning install warnings into build failures, and a configurable renv cache path.

◆ Prediction

With the injection surface closed and the defaults flipped, the next releases are more likely to be compatibility work against renv and pak than new generators.

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.
