What's new (v1.61 – v2.15)

A user-oriented overview of the releases since v1.61.0. The full, technical notes per version are under GitHub Releases.

v2.15.0 - Deeper exercises, compact lesson summary

  • Parametric exercises: a lesson can declare variables whose values are drawn fresh for every attempt; numeric answers are graded within a tolerance.
  • Three new exercise types: Hotspot, Parsons and Ordering, all authorable in the lesson creator.
  • Explanations after an answer; when you create a lesson from text, the AI can write them for you.
  • Compact lesson summary (result and XP) unless you have customised the summary sections; Detailed evaluation opens the full review.
  • Settings reorganised: labelled sections with a section bar on the Learning and Data tabs; the desktop app lists its installed plugins.
  • Refresh in My content applies every available set update at once, except those that would affect your progress; the Content hub has its own Create tab.
  • Legal notice and privacy policy in German and English; phone fixes for the iOS keyboard, crowded headers and the hub tab bars.

v2.14.0 - Game mode and arcade

  • Optional game mode: combo streaks, flying points, checkpoints, answer physics, hearts and countdown, and its own sound set.
  • Arcade minigames unlocked with XP (Lern-Memory, Snake, TicTacToe, Simon) plus flash rounds at set completion.
  • Mascot colour variants; avatar presets and frames tied to level and badge unlocks.
  • Set pages list their lessons with progress, leaving a lesson returns to its set, and a set-completion review collects every mistake of the set.
  • Settings gain a Diagnostics & Support tab.
  • Three new extension types from the creation wizard: speak and record, audio choice, audio tiles.

v2.13.0 - Convert exercise types

  • Change an exercise's type in place in the lesson editor; review history is carried over where the content survives, and the AI fills fields a conversion leaves empty.
  • Edit as a copy directly on a downloaded set; your copy is marked as your own edit, and re-importing a set keeps the review history of unchanged exercises.
  • The end-of-lesson correction round records your answers again, and read-aloud keeps the screen awake.

v2.12.0 - Start a set over

  • Start a finished set over as a fresh run while your spaced-repetition history continues.
  • Import provider keys from a Topos .alk export; Perplexity joins the AI providers.

v2.11.0 - Stable progress

  • Learning progress is anchored to stable exercise identities. A one-time local migration on the first start re-keys existing progress, so content corrections no longer orphan your review cards.
  • Matching exercises redesigned: help sits in the button row, the progress counter at the top.

v2.10.0 - Security: local-only by default

  • Update recommended. The desktop launcher and the compose file now bind the app to 127.0.0.1. Before, anyone on the same network could open it without authentication, including stored AI keys.
  • To reach the app from another device on purpose, set ADAPTIVE_LEARNER_BIND_ADDRESS=0.0.0.0 in .env, and only in a network you trust.

v2.9.0 - The launcher closes again

  • The downloaded launcher quits when you close its window, also on desktops without a system tray (for example Ubuntu GNOME). The app keeps running in Docker.
  • The lesson order you set now drives the learning sequence, and editing belongs to the individual lesson.

v2.7.0–v2.8.2 - Launcher uses a published image

  • The desktop launcher pulls a published, verified image instead of building on your machine (v2.7.0 was tagged but its changes first reached users with v2.8.0).
  • A recovery notice helps users whose review progress for the corrected Japanese, Korean and Chinese A1 lessons was orphaned; it offers a backup first and never runs automatically.
  • Security patch v2.8.1/v2.8.2 (update recommended): the v2.8.0 image showed a white page in image mode, and the bare container no longer starts in debug mode.

v2.6.0–v2.6.1 - New session chat, lessons from books

  • The session chat is rebuilt on assistant-ui.
  • Create lessons from a book: upload EPUB, TXT, MD or DOCX, pick the chapters, and generate a lesson per selected section.
  • The dictation editor accepts audio file uploads; content sets can be hidden through their manifest.
  • Launcher: context-aware Docker detection and a translated launcher UI.

v2.5.0 - Full exercise authoring

  • Every core exercise type is editable in the lesson creator, exercises can be added by hand, and multiple choice is authorable with a single or multiple answer mode.
  • An extension-authoring wizard covers categorization, error correction, reading comprehension and graded quiz; audio dictation joins as an extension type.

v2.4.0 - Authoring upgrade

  • Build a knowledge lesson from pasted textbook text, edit an existing own lesson, combine own lessons into a set, and upload card images.
  • Free-text exercises accept multiple answers and offer an AI second opinion on a wrong answer.
  • The AI settings tab links straight to key import.

v2.3.0 - Lesson player rework

  • Collapsible options panel, pause control in the footer and a slimmer title area.
  • Listen-first audio exercises.
  • More robust lesson and set file import and export.

v2.2.0 - Extension exercises

  • Four AI-authored extension exercise types plus native multiple choice.
  • A federated content-repository registry with a register-a-repo flow.
  • Simpler mobile navigation without the bottom tab bar.

v2.1.0 - Polish after the launch

  • Removing a content repository no longer leaves ghost progress on the Dashboard, in the review queue or in paused lessons.
  • Settings reorganised, Learning Path fixes, a discoverable Ask AI button and more robust content sync.

v2.0.0 - Public launch

  • The first version for a general audience: free and open source (MIT), offline-first, no account, spaced repetition, bring your own AI key, author and share your own lessons, installs as a PWA.
  • A launch milestone, not a technical break: no breaking change against v1.99.0.

v1.99.0 - Mobile hardening

  • Multiple choice as tappable answer buttons, which fixes tap misfires on iPhone.
  • Device fixes: iOS focus zoom, the iPhone delete menu and a remembered UI language.
  • Content-language filter in Discover, multi-select in My content, opt-in auto-advance and inline worked examples.

v1.97.0–v1.98.0 - Content hub redesign

  • My content shows only downloaded content; import and creation moved to the Import tab; list or grid view and a compact search and filter bar.
  • Collapsible desktop sidebar and per-set status (active, deferred, completed) with delete.
  • Vertical desktop navigation and deep links to a single set; cloze "select all that apply"; exam answers lengthen review intervals; passphrase-encrypted .alk export of AI keys.
  • Spanish and French translations reviewed.

v1.95.0–v1.96.0 - Lesson modes

  • Play a lesson or set as Practice, Exam, Timed or Shuffle, plus "train mistakes"; exam mode with delayed feedback, a result view, pass or fail and an XP bonus.
  • Reverse and Endless modes, invitation codes for sharing content and moving data from the online to a local install.
  • Export a set to a GitHub repository.

v1.92.0–v1.94.1 - Offline and launcher hardening

  • The installed PWA runs in browser-storage mode as intended, with fixes for the study guide, pronunciation and identity.
  • Desktop launcher: Docker-first flow with visible progress, configurable ports and a single persistent window; the Windows launcher builds again.
  • AI content-check dialogs scroll on desktop and show which provider and model ran the check.

v1.91.0 - Navigation restructuring

  • Primary nav cut from 12+ entries to 7 grouped entries (Dashboard, Lernpfad, Meine Inhalte, Entdecken, Fortschritt, Settings, Help) with no loss of function - every page stays reachable (Navigation).
  • Mobile bottom tab bar (Lernen / Inhalte / Entdecken / Fortschritt / Mehr) with a "More" bottom sheet.
  • ProgressHub (/progress) groups Overview / Statistics / My paths into tabs; DiscoverHub (/discover) gains an Import tab. Old links keep working via redirects.
  • PWA update banner no longer reappears after you accept an update.

v1.90.0 - AI exercise generation + auto-update

  • .alb ZIP backup format replaces the single JSON dump and now carries a localStorage snapshot too (Backup and restore).
