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 Knock?
Knock keeps absorbing customer data sources, puts an agent on top, and now aims at internal alerts.
The recent window splits into three strands: data sources (Clay, Amplitude) that remove the sync layer customers normally write between product data and messaging; workflow primitives (wait-for-event, branch rebasing) that make notification sequences behave like state machines; and an agent that reads the resulting message data in plain language. The newest addition points somewhere else — connecting a team's own Slack workspace to send to internal channels and recipients rather than to end users.

◆ 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.

6.3INFRA · APIS
Knock keeps absorbing customer data sources, puts an agent on top, and now aims at internal alerts.
◆ Current state
The recent window splits into three strands: data sources (Clay, Amplitude) that remove the sync layer customers normally write between product data and messaging; workflow primitives (wait-for-event, branch rebasing) that make notification sequences behave like state machines; and an agent that reads the resulting message data in plain language. The newest addition points somewhere else — connecting a team's own Slack workspace to send to internal channels and recipients rather than to end users.
◆ Where it's heading
The pattern is consistent: whatever a customer would otherwise build around Knock, Knock absorbs. Sync code became data sources, report building became the agent, and internal alerting — usually a separate webhook or a homegrown Slack app — becomes another recipient type. The management surfaces landing alongside it (categories, tags, saved views) are the housekeeping that accumulation forces.
◆ Prediction
More internal-destination work is the likely next step, extending the same use case beyond Slack, alongside further data sources following the Clay and Amplitude pattern.
