2026.06.3

Maintenance release rolling up everything since 2026.06.1 (the 2026.06.2 bump was never cut as a release). Focus areas: arm64/Qt6 board support, Sentry error tracking, viewer/webview crash-recovery, and server/celery resilience. Cutting this triggers the balena OTA deploy to all screenly_ose/anthias-* fleets; unpinned devices pull it and restart.

New boards & fleets

• feat(viewer,build,balena): add arm64/Qt6 pi3-64 board and the Rock Pi 4 fleet; keep 32-bit pi3 as legacy (#2985).

Observability

• feat(sentry): add Sentry error tracking to the Django services (#3007).
• feat(sentry): tag events with device type, host kernel, and board model (#3021).
• feat(sentry): stamp the release with the build hash and tag balena deploys (#3025).
• fix(sentry): stop reporting transient redis blips and client disconnects (#3018), also drop transient redis TimeoutError events (#3028), and silence the celery redis-backend reconnect-retry log (#3036).
• fix(celery): don't report the by-design codec rejection to Sentry (#3041).

Performance

• perf(viewer): pace Qt6 video frame delivery to scene-render capacity (#3006).
• fix(viewer): aspect-fit, gapless looping, and 30fps cap for pi1/2/3 video (#3004).

Viewer & webview

• fix(viewer): run PulseAudio so Qt 6 video plays with audio (#3001).
• fix(viewer): default x86 audio fallback to ALSA 'default' (#3038).
• fix(viewer): wait for cage's Wayland socket before spawning the webview (#3030).
• fix(webview): add a page-load watchdog so a stalled fetch can't freeze the display (#3003).
• fix(viewer): respawn the webview when it dies mid-D-Bus call (#3012), before setup's bus.get (#3020), and on a video-play D-Bus death rather than log+stop (#3031).
• fix(viewer): silence sh's monitor-thread crash report on webview exit (#3011).

Server & celery resilience

• fix(server): open SQLite with WAL journaling and a busy timeout (#3015).
• fix(celery): gate worker startup on applied database migrations (#3016).
• fix(celery): catch the asset-probe timeout instead of hard-killing the worker (#3017).
• fix(celery): store display_power in redis as a string, not a bool (#3032).
• fix(server): survive unreadable static files instead of crash-looping (#3026).
• fix(server): keep legacy host timezones from crash-looping Django (#3010).
• fix(server): stream the backup download so large libraries don't time out (#3005).
• fix(views): accept 12-hour AM/PM times in the asset edit form (#3002).
• fix(server): surface the exception detail in GitHub update-check warnings (#3023) and log release-check failures at warning, not error (#3019).

Uploads

• feat(server): offer HandBrake GUI steps for rejected video uploads (#3040).

Balena fleet automation

• feat(balena): hourly job to unpin pinned fleet devices (#2980).
• feat(balena): unpinner also rolls OS + supervisor updates (#2984).

Build & infra

• fix(build): ship libwebpdemux2 so pi3 Pillow can save WebP (#3042).
• fix(redis): persist data to the mounted volume so device identity survives recreation (#2983).
• fix(docker): pull the BuildKit frontend via mirror.gcr.io (#3008).
• Fixes SBOM (#2982).

Dependencies

• Bump uvicorn 0.32.1 → 0.49.0 (#2991), pyyaml 6.0.2 → 6.0.3 (#2993), django-stubs 6.0.3 → 6.0.5 (#2989), types-python-dateutil (#2992), and the github-actions group (#2994).

2026.06.1

Maintenance release focused on viewer video performance and display fixes. Cutting this triggers the balena OTA deploy to all screenly_ose/anthias-* fleets; unpinned devices pull it and restart.

Performance

• perf(viewer): render video via QML VideoOutput in a QQuickWidget (#2975) — replaces the toImage GPU-readback presentation path that capped presented framerate at ~8 fps on Pi 4 and ~11 fps on Pi 5 even with hardware decode; video now presents through the RHI sink at full rate.
• fix(viewer): play pi2/pi3 video via GStreamer HW pipeline (#2972) — replaces VLC with a GStreamer pipeline that uses the hardware decoder on Pi 2/Pi 3.

Fixes

• fix(viewer): default WLR_DRM_NO_ATOMIC=1 on x86 (#2978) — atomic-commit EBUSY can no longer freeze the display.
• fix(viewer): rotate Pi 4 (eglfs) display via QT_QPA_EGLFS_ROTATION (#2971) and emit 270° as -90 so portrait-inverted isn't stretched (#2973) — the rotation menu now works on Pi 4.
• fix(viewer): retry AnthiasViewer spawn so the armv7 WebEngine-init crash self-heals (#2969).
• fix(viewer): skip the Writeback connector in the eglfs headless guard (#2968).
• fix(viewer): fix two startup warnings surfaced by the log cleanup (#2979).

Housekeeping

• chore(viewer): drop the always-on Qt debug logging from the image (#2977).

2026.06.0

Maintenance release. Cutting this triggers the balena OTA deploy to all screenly_ose/anthias-* fleets; unpinned devices pull it and restart.

Fixes

• fix(balena): legacy data migration is now part of the canonical migrate_legacy_paths.sh (#2964, superseding #2963). Pre-rebrand devices kept their data in /data/.screenly; the post-rebrand container reads /data/.anthias, so on a balena upgrade the viewer came up with an empty playlist while the real DB sat untouched in the legacy path. The container now runs the same migration the host install does (against /data), and recovers devices that already booted the broken release (empty anthias.db → adopt the populated legacy screenly.db, keeping a .emptybak).
• fix(balena): pi4 dtparam=audio=on (#2961) — the multi-value dtparam never converged in balena's config.txt reconcile and reboot-looped the pi4 fleet; the single value stops the loop.

Notes

• Field devices already affected by the playlist wipe are also being remediated out-of-band; this release makes every legacy device self-heal on restart.

v2026.05.2

Highlights ✨

A stability and maintenance release hardening the balena fleets and the
upgrade path after the 2026.05.1 HW-decode overhaul. No new user-facing
features — all fixes.

Bug Fixes 🐞

• balena x86 — frozen on boot splash — quit Plymouth before cage
  starts so the viewer actually gets DRM master. Previously Plymouth held
  DRM master on x86 (libseat: Could not make device fd drm master), every
  atomic commit was rejected, and the screen stayed on the splash while the
  logs flooded with Swapchain for output 'DP-1' failed test (#2955)
• balena Pi 4 — no display — repair the full-KMS graphics overlay and
  manage fleet config.txt as IAC (balena-host-config.json), fixing a
  malformed dtoverlay="vc4-kms-v3d" that stopped the eglfs renderer from
  starting (#2947, #2949)
• Headless / slow-HDMI boards — crash loop — the linuxfb viewer (pi2/pi3)
  now waits for /dev/fb0 instead of aborting with heap corruption when no
  display is connected at boot; it self-heals on hotplug (#2959)
• Pi 5 — CEC probe core dumps — stop the HDMI-CEC diagnostics probe from
  dumping cores (which could fill the SD card and crash-loop services) (#2957)
• Upgraded devices — viewer crash loop — chown the config directory so
  upgraded devices stop crash-looping on a PermissionError writing
  anthias.conf (#2953)
• Deterministic file ownership — pin the viewer UID/GID across all images
  so bind-mounted config/asset ownership is stable across rebuilds (#2958)
• balena Releases page — stamp the real CalVer version into balena.yml
  so releases show 2026.5.x instead of 0.0.0+revN (#2952)

Docs 📚

• Document the rpi-imager 2.0.x macOS write-error when flashing images, and
  the workaround (#2948, #2950)

Upgrade Notes 🧭

• No action required. Devices upgrading from an older build pick up the
  config-dir chown and the pinned viewer UID/GID automatically, which
  resolves the anthias.conf PermissionError crash loop on first boot of
  the new release (#2953, #2958).
• balena Pi 4 fleets have their config.txt reconciled from
  balena-host-config.json at deploy time; any hand-edited dashboard
  config vars outside that file are pruned (#2947).

Full Changelog: v2026.05.1...v2026.05.2

v2026.05.1

Highlights ✨

• Pi 4 / per-board HW decode overhaul — embedded QtMultimedia inside AnthiasWebview, eliminating the two-process DRM contention that caused Pi 4 frame drops; added per-board HW decode dispatch and upload-time codec gating (#2905, #2885)
• 1 GB SBC enablement — low-RAM degradation gates so 1 GB boards (e.g. 1 GB Rock Pi 4) don't wedge under heavy assets (#2915)

• HDMI-CEC display on/off (experimental) — turn the connected TV on/off via CEC from settings (#2886)
• Migrate-to-Screenly wizard — opt-in UI flow that pushes an existing Anthias playlist into Screenly via the v4.1 API (#2876)
• Generic arm64 (Armbian) best-effort installer support (#2879)
• UI-driven screen rotation — portrait / landscape toggle without editing config.txt (#2882)
• x86 video playback under cage — dmabuf-wayland output with VAAPI HW decode (#2861)
• Anthias outbound traffic now identifies via a User-Agent (#2897)
• Release-flow split: master is testing, tagged releases are stable (#2854)

Security 🔒

• CodeQL alert sweep — path-injection, URL-redirection, stack-trace-exposure (#2884)
• CSRF: CSRF_TRUSTED_ORIGINS env var for host-rewriting proxies (#2901) + accept same-host Origin regardless of scheme (#2868)

Upgrade Notes 🧭

• Existing Pi 5 / mainline-KMS hosts: the upgrader now bind-mounts /dev/cec0 so HDMI-CEC works after upgrade (#2938).
• Legacy srly-ose-redis container is removed on upgrade (#2936).

WebView-v2026.05.0

WebView v2026.05.0

Adds the ``setReloadInterval(int seconds)`` D-Bus slot that backs the
per-asset webpage auto-refresh feature in PR #2841 / issue #2813.
The viewer arms a per-asset QTimer that calls ``currentWebView->reload()``
every N seconds; 0 disables. Timer is cleared on every ``loadPage`` /
``loadImage`` and only re-armed once the new page is actually visible
(via ``switchToNextWebView``) so it can't fire on the prior page during
a swap. Seconds are clamped to [0, 86400] to match the server-side
REFRESH_INTERVAL_S_MAX cap.

Built and tested against Qt6 trixie (x86); pi5/pi4-64 cross-build via
QEMU + pi2/pi3 Qt5 build paths exercised via the existing build-webview
workflow.

WebView-v2026.04.1

This release completes the Debian Trixie + Python 3.13 migration across the entire WebView stack — the Qt 5 toolchains for pi2/pi3 are rebuilt on trixie, and the Qt 6 webviews for pi4-64, pi5, and x86 are rebuilt against trixie's qt6-webengine-dev.

Supersedes WebView-v2026.04.0 (the first CalVer-tagged WebView release, which carried the Anthias rebrand of D-Bus / install paths / on-disk resources, the new pi4-64 Qt 6 path, and the webview-<calver>-<debian>-<board>.tar.gz artifact naming on bookworm). Use 2026.04.1 — 2026.04.0's bookworm tarballs are obsolete.

  • python2.7 from bullseye archive (trixie main dropped py2; pyenv was effectively broken because its PATH only loaded via ~/.bashrc, never reached docker run)
  • sysroot now ships harfbuzz/lcms2/re2/xml2 dev libs (chromium pdfium needed them on host and sysroot)
  • bzip2.pc copied from /usr/share/pkgconfig — was silently missing, made fontconfig probe fail and QtWebEngine quietly skipped
  • -webengine-proprietary-codecs enabled — H.264, AAC, MP3 in the resulting QtWebEngine
  • MAKE_CORES capped at min(nproc, 8) so chromium under qemu-arm doesn't OOM on >8-core hosts
  • trixie apt renames in webview/Dockerfile: libpng16-16 → libpng16-16t64 (time64 transition), libgst-dev → libgstreamer1.0-dev, libsqlite0-dev → libsqlite3-dev, libsrtp0-dev → libsrtp2-dev
• Trixie + Python 3.13 across all containers (server, celery, viewer, webview) — drops Balena base images, which never published a trixie tag and last refreshed in May 2025
• Pi keyring fetch hardened: HTTPS-only + SHA256 pinning on raspberrypi-archive-keyring and raspbian-archive-keyring .debs (the .deb is the trust anchor for everything fetched after it, so TLS alone wouldn't catch an upstream archive-side swap)
• bin/rebuild_qt5_toolchain.sh — out-of-band toolchain rebuild helper for pi2/pi3
• pi1 + 32-bit pi4 retired — surviving build matrix is pi2, pi3, pi4-64, pi5, x86; Qt 5 path is pi2/pi3 only

CI / release infrastructure

• Qt 5 builder image moved off Docker Hub onto GHCR: screenly/ose-qt-builder → ghcr.io/screenly/anthias-webview-qt5-builder (image + :buildcache tag), aligning with the rest of the anthias-* packages
• Qt 5 builder built inline in compile-webview-part-1 (no separate publish job)
• Registry-cache backend for the Qt 5 builder, mirroring docker-build.yaml
• USER root declared explicitly in webview/Dockerfile builder stage (sonar finding)

Viewer / pi4-64

• pi4-64 routes to mpv with HW decode via v4l2m2m-copy (not drm-copy)
• 64-bit balena base for pi4-64 viewer image
• libraspberrypi0 skipped on arm64 (it's armhf-only)
• audio_output setting honored in mpv

Webview UX (forum Tier-A bundle, #2778)

• No more white flash on dark URL assets — setBackgroundColor(Qt::black) on QWebEnginePage so the gap between load start and first paint is no longer white (forum t/6610)
• URL assets refresh every loop — QWebEngineProfile switched to memory HTTP cache + clearHttpCache on startup, instead of lingering stale for days from the on-disk cache (forum t/983)
• Auto Qt scaling on 4K+ screens — bin/start_viewer.sh now reads the active mode from /sys/class/drm/card*-*/modes and exports QT_SCALE_FACTOR (3840→2x, 5120→3x, 7680→4x); manual overrides win (forum t/6538)

Install / deps

• bin/install.sh accepts Python >=3.11 (was pinned to 3.11)
• Resolves release tags via refs/tags/ in clone_repo
• Django 4.2.30 → 5.2.13 (LTS)

x86	Qt 6 + WebEngine (trixie apt)	webview-2026.04.1-trixie-x86.tar.gz

Bookworm tarballs (pi1, pi2, pi3, pi4 32-bit) remain on WebView-v0.3.5 for legacy installs.

WebView-v2026.04.0

WebView v2026.04.0

First CalVer-tagged WebView release. Cut from the webview-fix PR
branch (PR #2767) ahead of merge so the viewer image build can fetch
the published artifacts on first try.

Highlights vs. the previous WebView-v0.3.12 release:

* Pi 4 64-bit (pi4-64) now produces a Qt 6 build alongside pi5 and
  x86, instead of being lumped with the legacy Qt 5 cross-compile.
* WebView binary, D-Bus service / object path, install dirs, and
  on-disk resources renamed from Screenly* to Anthias* (the parent
  Screenly Inc. attribution and ~/.screenly/ legacy paths are
  unchanged).
* Several latent correctness bugs fixed: stale image-reply race,
  animated GIF buffer ownership, page-load signal handler races,
  authenticationRequired signal-slot signature mismatch.
* Server host/port are now LISTEN/PORT env-overridable instead of
  hardcoded to anthias-server:8080.
* Artifact filenames switch to webview-<calver>-<debian>-<board>.tar.gz
  (Qt version and git short hash dropped); the Qt 5 toolchain
  archive (qt5-5.15.14-bookworm-<board>.tar.gz) keeps its Qt version.
