0.4.0

Follow-up to the Obsidian community-plugin review — clears the remaining advisories.

Changed

• Settings tab migrated to the declarative settings API (getSettingDefinitions), replacing
  the deprecated imperative display(). Controls bind through get/setControlValue; the
  theme-key chips and the export-theme picker use render. No change to which settings exist or
  how they behave.
• Documentation — the per-slide layout syntax (templates, density modifiers, the
  layout/column directives, inference) moved into a dedicated guide (docs/layouts.md,
  docs/layouts.de.md); the README links to it. This also clears the review's README
  "placeholder text" warning, which the literal <!-- layout --> directive examples had tripped.

Compatibility

• minAppVersion raised from 1.8.7 to 1.13.0 — the declarative settings API requires
  Obsidian 1.13.0. Users on older Obsidian releases should stay on 0.3.1.

0.3.1

Maintenance release for the Obsidian community-plugin review — no user-facing behaviour change.

Changed

• Obsidian lint compliance — cleared every eslint-plugin-obsidianmd finding from the
  community-plugin review without inline eslint-disable comments:
  • Static inline styles (off-screen iframe staging, the deck-scale transform origin, the
    preview overflow clip) moved into CSS classes (styles.css / STRUCTURE_CSS); only
    genuinely per-render values (the fit scale and box size) stay inline via setProperty.
  • The realm-safe HTML insertion in the renderer no longer uses innerHTML — it parses with
    DOMParser and imports nodes via importNode + replaceChildren (verified equivalent,
    including Mermaid SVG namespacing).
  • processFrontMatter access is typed instead of suppressed.
  • The two remaining file-scoped overrides (a lazy require("electron"), a shadowed
    deprecated display()) are unavoidable and documented in eslint.config.mjs.
• README — refreshed for the 0.3.0 template model (nine templates, density modifiers, deck
  slots, smart layout inference, media-fill) and bumped the release badge.

Fixed

• CHANGELOG 0.3.0 incorrectly said "eleven" templates; the template count is nine.

0.3.0

Added

• Template/layout model — eleven per-slide templates (default, title, section, quote,
  image-focus, two-column, columns-3, stat, cover-image) plus combinable density
  modifiers (compact, code-heavy), chosen with <!-- layout: <template> [modifier…] -->.
  In multi-column layouts the title spans all columns.
• Media that fills and centers — block images and Mermaid diagrams now occupy the available
  space, horizontally and vertically centered and scaled to fit (object-fit: contain), for both
  Obsidian ![[embeds]] and standard ![](…) images — instead of flowing small and left-aligned.
• Deck slots — header:, footer: and paginate: frontmatter render as floating corner
  slots (pagination shows n / N).
• Smart layout inference — with no explicit directive, a lone heading becomes section, a lone
  quote becomes quote, a lone image/diagram becomes image-focus, and <!-- column --> splits
  pick two-column/columns-3; an explicit <!-- layout --> always wins.
• Sparse slides compose vertically — slides with little content are vertically centered instead
  of clinging to the top.
• Per-theme code & Mermaid — a user .css theme can declare its highlight.js and Mermaid theme
  via /* sd-hljs: … */ and /* sd-mermaid: … */ header directives, so dark decks get dark code
  and dark diagrams.

Fixed

• Callout colours now derive from theme tokens, so dark themes render dark callouts without
  per-theme overrides.
• Mermaid diagrams scale to fill their area instead of being capped small.

0.2.0

Fixed

• PNG export no longer collapses inter-word spaces (switched the rasterizer from
  html2canvas to modern-screenshot).
• PDF export now prints the theme background (print-color-adjust: exact in PRINT_CSS) —
  dark themes no longer print on white.

Added

• Mobile support (isDesktopOnly: false) — the plugin now runs on iOS/iPadOS. All
  desktop-only APIs are platform-guarded. On mobile, PDF export writes a self-contained HTML
  file into the export folder and opens it via the OS (openWithDefaultApp); the user then
  prints or shares to PDF from there.
• Live theme switcher — the preview toolbar now has a theme dropdown for ephemeral try-on, a
  source label (from frontmatter / from default / ● unsaved) that disambiguates where the
  active theme comes from, and a Set button that writes theme: into the note's frontmatter
  via setNoteTheme (processFrontMatter). Fixes the „theme dropdown does nothing" confusion.
• User themes — drop .css files into the configurable themes folder (default
  Slide-Deck-Themes/); the frontmatter theme: value is the filename without the .css
  extension. Each file is a --sd-* token block with optional extra CSS; user themes inherit
  the built-in default theme's code-highlight and Mermaid styles. The Settings tab shows all
  valid theme keys live.
• Theme import/export — an Open in Finder button reveals the themes folder (drop files
  in); Export theme as .css writes any theme as an editable .css starting point; a toggle
  hides the themes folder in Obsidian's file explorer.

0.1.0

First release.

Added

• Markdown notes → slides — a --- separator line splits a note into individual slides;
  YAML frontmatter (theme:, aspect:, minFontPx:) controls deck-level directives.
• Live preview pane (Open presentation preview command) — renders the current note as a
  slide deck in the right sidebar, scaled to the pane width, with a source-jump link to each
  slide's originating line.
• Theme isolation — slides render inside a sandboxed iframe, so the active Obsidian theme
  can never leak into the preview or the exports; a deck looks identical regardless of the vault
  theme.
• Four built-in themes — default (light), dark, serif, and high-contrast, selected
  per deck via the theme: frontmatter; each carries a matching code-highlight and Mermaid theme.
• Per-slide layouts — title, two-column, image-focus, section, and quote, chosen
  per slide with an HTML comment directive (<!-- layout: two-column -->) and a <!-- column -->
  region separator.
• Custom CSS — an optional CSS snippet (Settings) is appended to the deck styles for branding
  and tweaks, in both the preview and the exports.
• Fit-or-warn readability — each slide auto-scales its content down to a configurable
  legibility floor (minFontPx, default 24 px); slides that would need even smaller text are
  flagged as overflowing (with a click-to-source warning) rather than becoming unreadable.
• PDF export (Export presentation to PDF command) — prints the deck (one slide per page,
  exact geometry) via the system print dialog (choose "Save as PDF"), theme-isolated.
• PNG image-series export (Export presentation to image series command) — captures each
  slide via html2canvas and writes numbered PNGs into a configurable export folder.
• KaTeX math — inline $…$ and display $$…$$ math.
• Code highlighting — fenced code blocks highlighted by highlight.js (per-theme stylesheet).
• Accessible callouts — > [!note], [!warning], [!danger], [!tip], [!info] blocks
  rendered with redundant coding: border colour + geometric shape + visible label word (not
  colour-only; WCAG 1.4.1).
• Mermaid diagrams — fenced ```mermaid ``` blocks rendered as SVG (per-theme).
• EN/DE interface — all UI strings follow Obsidian's language setting (English canonical,
  German supported); the settings tab and every notice are localized.
• Settings tab — default theme, minimum body font size, image-export scale, custom CSS, and
  export folder.
• Pure-core architecture — src/core/** is Obsidian-free and Node-testable; a core-purity
  check and a realm-safety check run as part of npm test, alongside a real-bundle smoke test
  and 63 unit tests.

Notes

• Desktop only (isDesktopOnly) — PDF/PNG export needs a full browser DOM.
