werf vs Incus: at a glance
What is werf?
Werf is running a v3 rewrite and a v2 maintenance line side by side, on four release channels.
Werf publishes into parallel channels — alpha, beta, ea, stable, and dev — and the recent entries show two lines moving at once. The 2.75.x releases are maintenance: a host-cleanup fix that stopped it wiping other werf versions' git cache, buildah retries when a cached image id is missing, serialized concurrent base-image pulls. The v3 line is where features land, with 3.0.0 alphas, a 3.0.2 patch, and a 3.1.0 dev build carrying embedded kubeconform schemas, additional patch files, and a per-project meta-repo safeguard.
What is Incus?
Incus settled its 7.0 LTS, then went straight back to a monthly feature cadence.
7.0.0 LTS landed in early May and became the supported baseline, followed by 7.0.1 as its first patch. The feature branch has not paused: 7.1 in May cleaned up the issues the LTS surfaced, 7.2 in June added migration-compatible hypervisor flags for stateful migration and aligned node-specific network configuration, and 7.3 at the end of July added native Windows and macOS installers to the build workflow, a QMP command timeout, and /32 and /128 addresses for OCI containers. Underneath, QEMU capabilities like SPICE, 9p and virtio audio are increasingly gated on runtime detection rather than assumed.

5.0INFRA · APIS
Werf is running a v3 rewrite and a v2 maintenance line side by side, on four release channels.
◆ Current state
Werf publishes into parallel channels — alpha, beta, ea, stable, and dev — and the recent entries show two lines moving at once. The 2.75.x releases are maintenance: a host-cleanup fix that stopped it wiping other werf versions' git cache, buildah retries when a cached image id is missing, serialized concurrent base-image pulls. The v3 line is where features land, with 3.0.0 alphas, a 3.0.2 patch, and a 3.1.0 dev build carrying embedded kubeconform schemas, additional patch files, and a per-project meta-repo safeguard.
◆ Where it's heading
The v3 work is a deploy-engine change more than a version bump: nelm is being pulled in and bumped, values-schema validation is becoming optional to stop service values breaking values.schema.json, and a meta-repo migration path is being built. Meanwhile the build layer is being hardened against concurrency — serialized pulls, retry on missing cached ids, Dockerfile COPY semantics fixed for --parents and --exclude in staged builds. The two lines share build fixes, with the same commits appearing in both 2.75.4 and 3.1.0.
◆ Prediction
Expect the v3 line to keep absorbing build fixes from 2.75.x while nelm and the meta-repo migration stabilise ahead of a wider v3 push. The 2.75.x channel looks like it will stay on bug fixes only.
Incus
5.0INFRA · APIS
Incus settled its 7.0 LTS, then went straight back to a monthly feature cadence.
◆ Current state
7.0.0 LTS landed in early May and became the supported baseline, followed by 7.0.1 as its first patch. The feature branch has not paused: 7.1 in May cleaned up the issues the LTS surfaced, 7.2 in June added migration-compatible hypervisor flags for stateful migration and aligned node-specific network configuration, and 7.3 at the end of July added native Windows and macOS installers to the build workflow, a QMP command timeout, and /32 and /128 addresses for OCI containers. Underneath, QEMU capabilities like SPICE, 9p and virtio audio are increasingly gated on runtime detection rather than assumed.
◆ Where it's heading
The rhythm is a monthly feature release running alongside a long-term branch, and the recent work leans toward reach rather than new primitives: clients built natively for Windows and macOS, translations updated in nearly every release, feature gating so the same daemon behaves correctly across host configurations. Stateful migration getting migration-compatible CPU flags is the most operationally significant item, since it is what makes live migration work across non-identical hosts.
◆ Prediction
The cadence in this window is a feature release roughly every four to six weeks with LTS patches interleaved, so a 7.4 is the expected next step. The entries give no indication of a headline feature queued for it.
