What is missSBM?

missSBM returns after four dormant years with a stricter API and a new refinement step.

The package fits stochastic block models to networks with missing data, covering both missing-at-random and informative sampling designs. After a run of releases from 2019 to 2022, the feed goes quiet until this year's 1.1.0, which breaks the control interface, exposes the block split and merge operations as testable instance methods, and adds a node-swap refinement pass that runs after variational convergence.

What is Resend?

Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.

Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.

missSBM returns after four dormant years with a stricter API and a new refinement step.

◆ Current state

The package fits stochastic block models to networks with missing data, covering both missing-at-random and informative sampling designs. After a run of releases from 2019 to 2022, the feed goes quiet until this year's 1.1.0, which breaks the control interface, exposes the block split and merge operations as testable instance methods, and adds a node-swap refinement pass that runs after variational convergence.

◆ Where it's heading

The new release is maintenance-driven in the best sense: it targets the parts of the codebase that were hard to test or easy to misuse. Replacing free-form control lists with a function of named, defaulted arguments turns silent typos into errors, and pulling the exploration logic out of the collection class makes the search algorithm independently testable without changing it. The polish step addresses a known weakness, reaching individually misclassified nodes that split and merge moves cannot fix.

◆ Prediction

Given the gap before this release, the near-term question is whether the cadence resumes at all; the refactoring it contains would support further algorithmic work if it does.

6.3

Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.

◆ Current state

Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.

◆ Where it's heading

Resend is treating agents as the next class of sending client and building the authorization and discovery plumbing they need before that traffic arrives. The progression is legible: authenticate third parties (OAuth), be callable (MCP), be installable per vendor (Codex, Claude), then be installable by standard. The Cancel Broadcast API is the first sign of the next phase — once non-human callers can schedule sends, the ability to revoke one programmatically stops being a convenience.

◆ Prediction

Authorization and discovery are covered and reversibility has now started; the remaining gap is what an agent is permitted to send in the first place, so scoped per-agent sending limits or approval gates before dispatch are the natural next piece.
