 ### Changed
 
 - **BREAKING** `rustyfarian-esp-hal-wifi`: removed the synchronous `WiFiManager::init`, `init_with_led`, `wait_connected`, `get_ip`, `take_sta_device`, and the `WifiDriver` trait impl, along with the `S: StatusLed` generic on `WiFiManager` and the `WifiError::{StartFailed, ConnectFailed, DisconnectFailed, RadioInitFailed}` variants — `esp-radio 0.18` removed direct `smoltcp` integration and made the bare-metal Wi-Fi controller async-only, so the sync surface no longer has a backing driver. The async path (`WiFiManager::init_async` + `AsyncWifiHandle`) is now the only public surface; the `embassy` Cargo feature is therefore effectively required alongside any chip feature
 - **BREAKING** `rustyfarian-esp-hal-wifi`: removed the `hal_c3_connect`, `hal_c6_connect`, `hal_c3_wifi_raw`, `hal_c6_wifi_raw`, and `hal_c6_connect_nonblocking_rgb` examples — all depended on the deleted sync smoltcp path; the three remaining `hal_*_async*` examples cover ESP32-C3 + ESP32-C6 in headless and LED-feedback variants
+- **April 2026 esp-hal stack wave** — coordinated workspace-wide bump of every bare-metal crate to exact pins (`Cargo.toml` `[workspace.dependencies]`): `esp-hal 1.0.0`→`=1.1.0`, `esp-rtos 0.2.0`→`=0.3.0`, `esp-radio 0.17.0`→`=0.18.0`, `esp-bootloader-esp-idf 0.4.0`→`=0.5.0`, `esp-alloc 0.9.0`→`=0.10.0`, `esp-println 0.16.1`→`=0.17.0`, `esp-backtrace 0.18.1`→`=0.19.0`; embassy ecosystem `embassy-executor 0.9`→`=0.10.0`, `embassy-net 0.7`→`=0.8.0`, `embassy-time 0.5`→`=0.5.1`, `embassy-sync` newly pinned at `=0.8.0`. `smoltcp` is now exact-pinned at `=0.12.0` but is no longer a direct dependency of `rustyfarian-esp-hal-wifi` — `esp-radio 0.18` removed the `smoltcp` feature in favour of `embassy-net-driver`. Coordinated with `rustyfarian-ws2812`'s April 2026 wave (see `docs/features/archive/esp-hal-stack-upgrade-april-2026-v1.md`)
+- ws2812 cross-repo dependencies (`led-effects`, `rustyfarian-esp-idf-ws2812`, `rustyfarian-esp-hal-ws2812`) re-pinned from `tag = "v0.4.0"` to `tag = "v0.5.0"` — v0.5.0 is the April 2026 wave release that ships the matching exact pins for `esp-hal`/`esp-rtos`/`esp-radio`, so the resolved feature graph stays unified with this workspace's bare-metal stack
+- **BREAKING** `rustyfarian-esp-hal-wifi`: API renames flowing through from `esp-radio 0.18` — `WifiDevice` → `Interface`, `ModeConfig::Client(ClientConfig)` → `Config::Station(StationConfig)`, `Interfaces.sta` → `.station`, `WifiEvent::StaDisconnected` → `StationDisconnected`, `WifiError::Disconnected` is now a tuple variant carrying `DisconnectedStationInfo`, `controller.is_connected()` returns `bool` directly (not `Result`), `controller.connect()`/`disconnect()` are async-only (`connect_async`/`disconnect_async`), `controller.wait_for_event(StaDisconnected)` becomes `wait_for_disconnect_async`, `esp_radio::wifi::new()` is now `(WIFI, ControllerConfig)` (the radio init parameter is gone — radio init is implicit)
+- **BREAKING** `rustyfarian-esp-hal-wifi`: `set_config` is now idempotent in `esp-radio 0.18` and implicitly starts the controller and initiates association — the explicit `start()`/`connect()` calls that existed in 0.17 are no longer needed (or available)
+- `rustyfarian-esp-idf-espnow`: `default_interface()` always returns `WifiInterface::Sta` — `init_with_radio()` starts in STA mode, not AP (fixes `ESP_ERR_ESPNOW_IF` on send)
+- `sdkconfig.defaults`: added `CONFIG_ESP_WIFI_NVS_ENABLED=n` to prevent stale WiFi credential caching

+# Release Plan
+
+Release process for `rustyfarian-network`.
+Covers versioning, pre-flight checks, publish targets, and post-release steps.
+
+## Versioning
+
+- **Scheme:** SemVer (pre-1.0 — minor bumps signal breaking changes)
+- **Lockstep:** all 13 workspace crates move together at the same version
+- **Snapshot convention:** none (we tag the release commit, no `-SNAPSHOT` between releases)
+- **Who decides version:** maintainer, based on `CHANGELOG.md` `[Unreleased]` content
+
+## Branch and Tag Convention
+
+- **Release branch:** `prepare-release` → merged to `main` after publish
+- **Tag format:** `vX.Y.Z` (annotated)
+- **Tagging:** manual on the release commit on `main`
+
+## Pre-flight Checklist
+
+Before any release:
+- [ ] Working tree clean on `prepare-release` (untracked `review-queue/` is OK)
+- [ ] `just fmt` clean
+- [ ] `just verify` passes (fmt-check + cargo deny + check + clippy)
+- [ ] `just test` passes (all pure-crate host tests)
+- [ ] At least one hardware example builds via `just build-example <name>` for each tier touched (sanity check; not exhaustive)
+- [ ] `cargo audit` shows no new advisories beyond those allow-listed in `deny.toml`
+- [ ] `CHANGELOG.md` `[Unreleased]` has entries for the target version
+- [ ] `[workspace.package].version` in root `Cargo.toml` matches the target version; no member crate overrides it (each declares `version.workspace = true`)
+
+## Version Bump
+
+Single source of truth: `[workspace.package].version` in the root `Cargo.toml`.
+Each member crate inherits via `version.workspace = true`, so a release bump is one edit.
+
+Post-release bump target: none (next-version bump happens when the next `[Unreleased]` block is finalised)
+
+## Publish
+
+**Target registry:** none — tag-only on GitHub
+**Tag command (on the release commit):**
+
+```sh
+git tag -a vX.Y.Z -m "vX.Y.Z"
+git push origin vX.Y.Z
+```
+
+**Branch push:** `git push origin main` (or open a PR from `prepare-release` → `main` and merge)
+**Credentials:** standard GitHub push credentials (no registry tokens needed)
+**Signing:** not required (commit / tag GPG signing optional, follow whatever git is already configured to do)
+
+## Changelog
+
+**Location:** `CHANGELOG.md`
+**Format:** Keep a Changelog 1.1.0
+**Process:** rename `## [Unreleased]` to `## [X.Y.Z] - YYYY-MM-DD`; create a fresh empty `## [Unreleased]` block above it for next cycle
+
+## GitHub Release
+
+- [ ] Create release page at: `https://github.com/datenkollektiv/rustyfarian-network/releases/new`
+- [ ] Use tag `vX.Y.Z`
+- [ ] Title: `vX.Y.Z`
+- [ ] Body: paste the `## [X.Y.Z]` section from `CHANGELOG.md`
+- [ ] No artifact attachments (workspace is library crates; users consume via git dep)
+
+## Post-release Steps
+
+- [ ] Merge `prepare-release` → `main` (fast-forward)
+- [ ] Update `docs/ROADMAP.md` if any items shipped in this release are still listed as in-progress
+- [ ] Verify the GitHub release page is publicly visible and the tag resolves
+
+## Rollback Procedure
+
+If a release must be retracted after tagging:
+1. Delete remote tag: `git push --delete origin vX.Y.Z`
+2. Delete local tag: `git tag -d vX.Y.Z`
+3. Delete the GitHub release page (via web UI or `gh release delete vX.Y.Z`)
+4. Revert the release commit on `main`: `git revert <release-commit-sha>` and push
+
+Note: because nothing is published to a registry, rollback is fully reversible.
+
+## Release Record Location
+
+Each release produces files in `release/`:
+1. `YYYY-MM-DD-<version>-preflight.md` — pre-flight assessment
+2. `YYYY-MM-DD-<version>-plan.md` — ordered execution plan
+3. `YYYY-MM-DD-<version>-record.md` — what was published and what remains
