+## [Unreleased]
+
+Pure CI / repository housekeeping; no runtime changes since v0.3.1. All
+items below shake out workflow-loop bugs exposed by the v0.3.1 release
+flow on Gitea Actions.
+
+### Fixed (CI)
+
+- `build-arm64.yaml` no longer triggers on tag pushes. `release.yaml`
+  already produces the ARM64 disk image as part of the release flow, so
+  triggering both on the same tag wasted an hour of Odroid runner time
+  on a duplicate kernel build. (`04a5cd2`)
+- The gated `build-iso-amd64` job in `release.yaml` (`if: false` until an
+  amd64-linux runner exists) used to advertise `runs-on: amd64-linux`.
+  With no matching runner, Gitea left the job queued forever and the
+  overall workflow run never transitioned to `success` — even though
+  every load-bearing job had finished and the release was already
+  published. Now uses `runs-on: ubuntu-latest` so any runner picks the
+  job up just long enough to evaluate `if: false` and mark it `skipped`.
+  (`fb24e64`)
+- `build-arm64.yaml` now ignores workflow-file, docs, and `*.md` changes
+  via `paths-ignore` (`.gitea/workflows/**`, `.github/workflows/**`,
+  `docs/**`, top-level `*.md`, `.gitignore`). Workflow- / docs-only
+  commits no longer kick off a 60-minute kernel rebuild on the Odroid.
+  Any change to a kernel fragment, init script, or build script still
+  triggers the full build, as intended. (`e1b8a69`)
+
+### Changed
+
+- `.gitignore` now excludes `.env`, `.env.*`, `*.token`, `*.pat` to keep
+  Gitea PATs and other credentials used during release ops from being
+  accidentally committed. (`48267e1`)

 An immutable, bootable Linux distribution purpose-built for [KubeSolo](https://github.com/portainer/kubesolo) — Portainer's ultra-lightweight single-node Kubernetes.
 
-> **Status (v0.3.0):** x86_64 and generic ARM64 (UEFI / virtio / mainline kernel) both build and boot end-to-end. Update agent has an explicit state machine, OCI registry distribution alongside HTTP, channel + maintenance-window + version-stepping-stone gates, and auto-rollback. ARM64 Raspberry Pi support remains paused pending physical hardware. See [docs/release-notes-0.3.0.md](docs/release-notes-0.3.0.md) for the full v0.3.0 changelog.
+> **Status (v0.3.1):** First fully-validated generic ARM64 release. x86_64 and ARM64 (UEFI / virtio / mainline kernel) both build and boot end-to-end; v0.3.1 closes the dual-glibc, nftables address-family, and kube-proxy expression-module gaps that kept v0.3.0 from reaching a Ready node on ARM64. Validated end-to-end under QEMU virt + HVF on Apple Silicon: `kubectl get nodes` reports `Ready`, CoreDNS, local-path-provisioner, and an nginx test workload all `Running`.
