What is ESPEasy?

One release a year, each one a filesystem or networking rewrite you must plan for.

ESPEasy publishes rarely — five builds across two years — and each one accumulates hundreds of commits. The July 2026 mega build reworked how networking is handled and added support for Espressif's newer silicon: ESP32-P4, -C5 and C61. The 2025 build was the last to ship SPIFFS for ESP32, forcing a LittleFS conversion on everyone who upgrades past it. Release notes are raw commit lists grouped by contributor.

What is Skipper?

Skipper adds RFC 9421 HTTP Message Signatures and delivers 21% RouteGroup load time improvement

Skipper v0.27 is shipping at a steady maintenance cadence with two functional additions of note: v0.27.96 adds native RFC 9421 HTTP Message Signatures filter support — a 2023 IETF standard for request signing gaining traction in financial services and regulated APIs. v0.27.95 delivers a shared parse cache across RouteGroups, producing a measured 21% load time reduction, 12% lower memory, and 26% fewer allocations on a 200-RouteGroup benchmark.

One release a year, each one a filesystem or networking rewrite you must plan for.

◆ Current state

ESPEasy publishes rarely — five builds across two years — and each one accumulates hundreds of commits. The July 2026 mega build reworked how networking is handled and added support for Espressif's newer silicon: ESP32-P4, -C5 and C61. The 2025 build was the last to ship SPIFFS for ESP32, forcing a LittleFS conversion on everyone who upgrades past it. Release notes are raw commit lists grouped by contributor.

◆ Where it's heading

The project's pattern is long test cycles followed by a build that changes something foundational — filesystem, networking, MCU support — and asks users to back up settings before upgrading. Between those, only hotfixes appear. Development is heavily concentrated in one maintainer's commit stream, with the rest of the contributor list handling docs, build scripts and individual plugins.

◆ Prediction

Given the cadence, the next build is likely months out and shaped by whatever the current test-build issue accumulates; the newly added MCU families are the obvious place for follow-up plugin and peripheral work.

Skipper adds RFC 9421 HTTP Message Signatures and delivers 21% RouteGroup load time improvement

◆ Current state

Skipper v0.27 is shipping at a steady maintenance cadence with two functional additions of note: v0.27.96 adds native RFC 9421 HTTP Message Signatures filter support — a 2023 IETF standard for request signing gaining traction in financial services and regulated APIs. v0.27.95 delivers a shared parse cache across RouteGroups, producing a measured 21% load time reduction, 12% lower memory, and 26% fewer allocations on a 200-RouteGroup benchmark.

◆ Where it's heading

Skipper is building out its security posture at the proxy layer: RFC 9421 request signing, Redis L2 cache (v0.27.92), and security header handling improvements (v0.27.88) suggest a consistent push toward production-grade security primitives without architectural breaks. The performance improvements in v0.27.95 address real-world Kubernetes clusters where large RouteGroup counts are common.

◆ Prediction

RFC 9421 support will likely get expanded configuration options — signing key rotation, policy enforcement modes, per-route key selection — as Zalando's internal adopters surface operational requirements for the filter.
