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 ESPHome?

ESPHome 2026.9.0 ships template climate component, OTA encryption with API key, and ESP-NOW for ESP32-P4

ESPHome 2026.9.0 is out, capping a beta cycle that added a template climate component (a long-requested flexible HVAC control primitive), OTA encryption keyed to the device's API key (hardening the update path), and ESP-NOW over hosted shim for the ESP32-P4. The beta cycle also included a systematic RAM allocation safety pass across the codebase — heap exhaustion now returns an error instead of panicking. Monthly releases continue landing at a consistent pace.

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.

ESPHome 2026.9.0 ships template climate component, OTA encryption with API key, and ESP-NOW for ESP32-P4

◆ Current state

ESPHome 2026.9.0 is out, capping a beta cycle that added a template climate component (a long-requested flexible HVAC control primitive), OTA encryption keyed to the device's API key (hardening the update path), and ESP-NOW over hosted shim for the ESP32-P4. The beta cycle also included a systematic RAM allocation safety pass across the codebase — heap exhaustion now returns an error instead of panicking. Monthly releases continue landing at a consistent pace.

◆ Where it's heading

ESPHome is expanding in two directions simultaneously: broader hardware support (ESP32-P4, BK72xx BLE, new platform components) and more robust runtime behavior (RAMAllocator pattern, use-after-free fixes, better BLE-WiFi coexistence). The template climate component is the most user-visible addition — it brings custom HVAC logic into ESPHome's declarative model, reducing the need for external Home Assistant automations. Audio stack (i2s, resampler, mixer) reliability is also a consistent focus.

◆ Prediction

The 2026.10.0 cycle will likely continue the RAMAllocator pattern across remaining allocating code paths and add more ESP32-P4-specific features. Audio (voice assistants, speakers) will stay a top area given the ongoing i2s reliability work.
