What is FOSSA CLI?

fossa-cli's releases are ecosystem-by-ecosystem repairs to how lockfiles are read.

Releases arrive every one to three weeks and almost all of the substance is per-ecosystem dependency resolution. In this window: Node workspaces declared with a leading ./ now match, npm v3 lockfiles get target-level dependency scoping, pnpm lockfile handling was refactored, and sbt 1.4+ projects with an explicit DependencyTreePlugin route to the built-in command. Around that sit operational adjustments — the default scan timeout raised from 30 seconds to a minute, release-group project resolution moved to a server-side lookup — and two tags that carry nothing but a Themis version bump or a release cut.

What is Resend?

Resend exposes webhooks as a fully programmable surface — including MCP server support — while completing API parity across broadcast management.

Resend shipped at least one changelog entry every day in the last three weeks of September 2026. The product is systematically closing the gap between what's configurable in the UI and what's accessible via API: segment renaming, API key renaming, clicked-link retrieval, and now full webhook management are all programmable. The Headless Webhook API, released September 16, is the most significant change — developers can now create and configure webhook endpoints entirely via API, CLI, SDK, or MCP server, removing the last major operation that required a browser visit.

fossa-cli's releases are ecosystem-by-ecosystem repairs to how lockfiles are read.

◆ Current state

Releases arrive every one to three weeks and almost all of the substance is per-ecosystem dependency resolution. In this window: Node workspaces declared with a leading ./ now match, npm v3 lockfiles get target-level dependency scoping, pnpm lockfile handling was refactored, and sbt 1.4+ projects with an explicit DependencyTreePlugin route to the built-in command. Around that sit operational adjustments — the default scan timeout raised from 30 seconds to a minute, release-group project resolution moved to a server-side lookup — and two tags that carry nothing but a Themis version bump or a release cut.

◆ Where it's heading

The work is breadth-of-accuracy, not new features: every release closes a case where a real project layout produced an incomplete or wrong dependency graph. That is the correct shape for a compliance scanner, where a missed transitive dependency is a failed audit rather than a rough edge. The steady stream of package-manager-specific fixes suggests coverage is still being driven by customer projects that scan badly, which means the tail of ecosystems is long and being worked through one at a time.

◆ Prediction

Expect the pattern to continue with another package manager's lockfile format — the timeout increase hints scans are also getting slower on large monorepos, so performance work on the same paths is likely next.

Resend exposes webhooks as a fully programmable surface — including MCP server support — while completing API parity across broadcast management.

◆ Current state

Resend shipped at least one changelog entry every day in the last three weeks of September 2026. The product is systematically closing the gap between what's configurable in the UI and what's accessible via API: segment renaming, API key renaming, clicked-link retrieval, and now full webhook management are all programmable. The Headless Webhook API, released September 16, is the most significant change — developers can now create and configure webhook endpoints entirely via API, CLI, SDK, or MCP server, removing the last major operation that required a browser visit.

◆ Where it's heading

Resend is converging on a fully API-first email infrastructure platform. The MCP server integration with webhooks is a deliberate move toward the AI-native developer toolchain, signaling that Resend sees infrastructure automation and LLM-driven workflows as a real use case, not a footnote. The SSO addition on September 1 continues enterprise expansion. With API parity nearing completion, the next surface to fill is analytics — open rates, bounce rates, and delivery event streams are not yet exposed programmatically.

◆ Prediction

Full broadcast analytics via API is the most visible gap remaining — List Clicked Links shipped September 15, which is one piece, but open-rate and delivery-event endpoints are likely next. A webhook event stream or subscription API would round out the headless infrastructure story.
