What is Honeycomb?

Canvas agents gain memory, and onboarding moves into the editor

Honeycomb is building an investigation agent rather than a query tool. Automatic Investigations now dispatch to Canvas agents carrying awareness of recent firings of the same Trigger, Burn Alert or Anomaly, so repeat issues get pinpointed against prior hypotheses. Around that sit Anomaly Detection in open beta, MCP-based onboarding that instruments a codebase from the editor, Canvas connectors for Linear and GitHub, and telemetry stats in the Activity Log.

What is rextendr?

rextendr put Rust-backed R packages in the browser, then tore itself down for a 1.0.0 rebuild

rextendr is the R-side toolchain for extendr, scaffolding and compiling R packages with Rust internals. The package is mid-teardown: the 0.4-final tag in October 2025 warns that main may not work as expected and directs users to install from that tag, and April 2026's release is titled as one more developer release before 1.0.0. Meanwhile the CRAN-facing 0.4.x line did the substantive work.

Canvas agents gain memory, and onboarding moves into the editor

◆ Current state

Honeycomb is building an investigation agent rather than a query tool. Automatic Investigations now dispatch to Canvas agents carrying awareness of recent firings of the same Trigger, Burn Alert or Anomaly, so repeat issues get pinpointed against prior hypotheses. Around that sit Anomaly Detection in open beta, MCP-based onboarding that instruments a codebase from the editor, Canvas connectors for Linear and GitHub, and telemetry stats in the Activity Log.

◆ Where it's heading

Every recent release reduces what a human has to know before Honeycomb is useful. Detection needs no thresholds, onboarding needs no manual SDK setup, and now the agent retains context across alert firings instead of starting cold each time. Canvas is becoming the product's centre of gravity — the surface that reads connectors, edits Triggers and SLOs, and accumulates conclusions.

◆ Prediction

Anomaly Detection should widen beyond error rate and presence to latency and request rate as it approaches GA, and the alert-history awareness added here is the groundwork for agents that correlate across different alerts rather than repeat firings of one.

rextendr put Rust-backed R packages in the browser, then tore itself down for a 1.0.0 rebuild

◆ Current state

rextendr is the R-side toolchain for extendr, scaffolding and compiling R packages with Rust internals. The package is mid-teardown: the 0.4-final tag in October 2025 warns that main may not work as expected and directs users to install from that tag, and April 2026's release is titled as one more developer release before 1.0.0. Meanwhile the CRAN-facing 0.4.x line did the substantive work.

◆ Where it's heading

Two threads run in parallel. The first is reach: 0.4.0 added WebR support out of the box for all extendr packages by enabling the wasm32-unknown-emscripten target, and 0.4.2 followed with the panic and link-time-optimization settings needed to make those builds actually work. The second is CRAN compliance — use_cran_defaults(), vendor_pkgs(), automatic SystemRequirements fields, and configure scripts, all aimed at getting Rust-powered packages accepted on CRAN. The rebuild announced in 0.4-final is a third thread whose shape the entries do not reveal.

◆ Prediction

The stated destination is 1.0.0 built on the new Makevars-linked build process, so that release is the next milestone. What the revamp changes for existing extendr packages is not described in any entry here.
