Foliuna 0.5.0-rc.2 · Windows release candidate

Foliuna's updated Windows candidate adds full-page post viewing and real system fullscreen, with a custom title bar and video controls.

• Move between posts with the arrow keys in details or fullscreen. Zoom, fit and pan images while preserving their proportions.
• Use the custom video controls for playback, seeking, volume and speed; moving into and out of fullscreen preserves playback state.
• The fictional offline demo has been removed. Gallery and Collections still work offline with saved media.
• The refreshed website and README show actual safe e621 forest searches, with artist/source credits and a paused/reduced-motion option for the five-second image rotation.

Download the Setup executable, or extract the complete ZIP and open Foliuna.exe. No Node.js or terminal is needed. This is an unsigned prerelease; compare the download against SHA256SUMS.txt.

All eight built-in boorus and compatible custom connections, encrypted per-site credentials, explicit original downloads, SHA-256 deduplication, immutable source/tag history, portable sidecars, Gallery and Collections remain available. Existing schemas and user libraries are preserved.

Verification: 246 local unit/component tests and 8 actual Electron journeys; 28 packaged files, seven fuses and embedded ASAR/file/block integrity; hardened packaged-app startup, local media, viewer isolation, settings and shutdown. The NSIS embedded executable and ASAR exactly match the verified app. Installation/uninstallation was not rerun, because the test guard found an existing user Foliuna shortcut and preserved it. GitHub independently passed Windows and Android API 26/36 on source 0b6d354.

Physical phone testing of this candidate, live authenticated providers, wider hardware/codecs and physical power-loss behavior remain unverified. No real API key or personal archive was used in verification.

Back up the complete library, including its hidden .foliuna folder and collection snapshot, while the app is closed. On Android, export before uninstalling or changing signing identity. Existing published releases remain available.

Foliuna Android 0.1.0-preview.2 · testing preview

Foliuna Android 0.1.0-preview.2

Debug-signed testing preview for Android 8.0+ (API 26), targeting Android 16 (API 36). Separate app identity: io.github.justypixels.foliuna.preview. The existing Windows release remains available.

This update adds full-page post details, immersive system fullscreen, swipe navigation, aligned bottom navigation icons, a custom video player and legacy-WebView thumbnail sizing. The fictional offline demo has been removed.

Includes eight booru connections and compatible custom Danbooru/Gelbooru sites, native paced networking, Android Keystore credentials, tag search, media details/fullscreen, explicit downloads, SHA-256 deduplication, offline Gallery, Collections and portable export.

Install and backup

Download Foliuna-Android-0.1.0-preview.2-debug.apk and compare its SHA-256 with SHA256SUMS.txt. Android may request permission to install from the app opening the file; follow current Android installation/developer verification guidance. This is a debug-signed preview, not a production or Play release.

Export before uninstalling, clearing storage or changing signing identity: these can remove your private archive. Use Settings → Export library… and retain the complete completed folder, including .foliuna/collections.json and media sidecars. Windows can rebuild Gallery and Collections by choosing that folder and importing sidecars. Credentials and private settings are excluded.

Downloads run only while Foliuna is foreground. Flash, floating windows, background transfers, incoming Android libraries and synchronization are deferred. Device codec support varies.

Actual verification

• Final local API 26 phone and API 36 tablet: 10 tests each, zero failures/skips, covering native validation/encryption/pacing, downloads/deduplication/recovery, offline membership, WebView restrictions, Back/rotation/keyboard, GIF/video and destination-picker export. Android lint: zero errors.
• Native snapshots and actual folder-picker exports from both APIs reconstructed categorized tags, immutable source history, deduplication and Collections with the unchanged Windows importer and no network requests.
• Windows: 246 unit/component tests, 8 desktop journeys, verified installer/ZIP and hardened packaged-app smoke checks.
• GitHub independently passed Android API 26/36 and Windows; website checks cover project paths and phone/tablet/desktop layouts.
• An earlier build passed 9 tests on an authorized Moto g14 (API 34, ARM64, WebView 155); its automatic destination-selection test was intentionally skipped. The phone was unavailable for a final-candidate reinstall. No real keys or personal library were used.

Live authenticated provider access, broader physical devices/codecs and physical power-loss/storage behavior remain unverified. Source: 0b6d354. See attached verification records for APK hash/debug-certificate fingerprint and check details.

Foliuna 0.5.0-rc.1 · Windows release candidate

Foliuna's first Windows release candidate combines booru search with an offline gallery and personal archive.

Download and open

• Setup.exe: install for your Windows account, then open Foliuna from Start.
• Windows-x64.zip: extract the entire folder and open Foliuna.exe. No Node.js or terminal is needed.
• Unsigned prerelease: Windows may show an unknown publisher warning. The app and installer do not have a publisher certificate. Checksums are provided in SHA256SUMS.txt.

Included

• e621, Danbooru, Gelbooru, Rule34.xxx, Safebooru, AIBooru, Yande.re, Konachan and custom compatible Danbooru/Gelbooru connections.
• Safe-only default, tag suggestions, pages/infinite scroll, post navigation, proportional/cropped grids, sample/full-size images, video/GIF and isolated Ruffle playback.
• Windows-encrypted per-site API keys, explicit original downloads, SHA-256 deduplication, source/tag history and portable media sidecars.
• Offline Gallery and portable local Collections.
• Shorter interface text, fewer card rerenders and duplicate/repeated-image requests.
• Hardened Electron fuses, integrity-checked application archive and verified release payload.

Verification and limits

243 automated tests, eight Windows desktop journeys, packaged app checks and temporary install/run/uninstall checks passed locally on Windows 10 x64. The attached verification reports describe the tested payload and source commit. Production dependency audit: zero advisories. Eight moderate build-tool dependency findings remain outside the shipped runtime.

Windows 11/ARM64, real-key authenticated provider access, physical removable-drive/power-loss recovery and every codec/Flash feature are not verified. Site restrictions are respected; an API key does not bypass them. No automatic updates, telemetry, ads or paywalls are included.

Back up the entire library, including its hidden .foliuna folder and collection snapshot, while the app is closed. Profile settings remain under %APPDATA%\Foliuna; uninstall preserves the profile and chosen library. Database v3 and v1 sidecars/collection snapshots are unchanged.
