What is crane?
Crane is turning into the table-and-plot layer for Roche's clinical output stack.
Crane publishes release candidates rather than finals, and the whole of 0.3.2 is carried by a single rc2 body — its two sibling tags are one-line styling commits, one of them tagged with an unsubstituted vX.Y.Z placeholder. The rc2 notes run to dozens of additions across regression tables, line plots and hierarchical rate tables.
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.

Crane is turning into the table-and-plot layer for Roche's clinical output stack.
◆ Current state
Crane publishes release candidates rather than finals, and the whole of 0.3.2 is carried by a single rc2 body — its two sibling tags are one-line styling commits, one of them tagged with an unsubstituted vX.Y.Z placeholder. The rc2 notes run to dozens of additions across regression tables, line plots and hierarchical rate tables.
◆ Where it's heading
The package is moving from plotting helpers to a full analysis-output layer: mixed models for repeated measures, pairwise Cox results, risk-management-plan tables and adverse-event incidence rates all arrive in one cycle, and the annotation machinery underneath was rebuilt for reliable table-to-axis alignment. Defaults are being pulled toward SAS and rtables output — the log-rank test now uses survival::survdiff instead of coin, and survfit confidence intervals default to plain rather than log.
◆ Prediction
Expect a 0.3.2 final close behind rc2, and the deprecated g_lineplot() family to be removed once gg_lineplot() and annotate_gg() have settled.
Knock
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.
