Apptainer
Apptainer 1.6 candidate adds delta images that rebuild only what changed.
A side-by-side editorial comparison of ESPEasy and k0s — release velocity, themes, recent moves, and the top alternatives to consider.
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.
k0s ships another four-branch patch round, with an IPv6 service CIDR fix on 1.37 and 1.36.
On November 3 k0s released v1.37.2, 1.36.6, 1.35.10 and 1.34.13 within minutes of each other. The 1.37 and 1.36 releases remove a size limit on IPv6 service CIDRs and update containerd to 2.3.6; 1.37.2 also bumps kine, ORAS and troubleshoot. The 1.35 and 1.34 branches take only Kubernetes patch updates.

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.
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.
On November 3 k0s released v1.37.2, 1.36.6, 1.35.10 and 1.34.13 within minutes of each other. The 1.37 and 1.36 releases remove a size limit on IPv6 service CIDRs and update containerd to 2.3.6; 1.37.2 also bumps kine, ORAS and troubleshoot. The 1.35 and 1.34 branches take only Kubernetes patch updates.
k0s now maintains four branches on a shared patch cadence, roughly one coordinated round a week after the 1.37 line opened on October 27. Fixes and dependency updates land on the newest two branches, while older ones receive only Kubernetes patches, which indicates where active support is concentrated.
Expect the next coordinated round to follow upstream Kubernetes patch releases, with 1.34 likely to stop receiving updates as 1.37 matures.
