# Changelog

All notable changes to OciDeck are documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and the project aims to follow [Semantic Versioning](https://semver.org/).

## [Unreleased]

### Added
- **Source-code slides** — a "code sheet" with per-language syntax highlighting,
  stored as a fenced code block. Background, text colour and monospace font are
  part of the style profile, with a syntax-colouring toggle; turning it off renders
  the block in a single colour (e.g. green on black for a CRT-terminal look). The
  code is sized to fill the panel — larger when there's room, smaller for long
  fragments.
- **Charts** — bar, line, pie, and **spider/radar** chart slides. Data is entered
  in an in-app grid or imported from CSV; the spec is stored as JSON in a ```chart
  block. Data can stay inline or be linked to a CSV in a separate `data/`
  directory. Rendered natively in-app (preview, presenter, PDF, PPTX) and as
  self-contained SVG in the HTML export.
  - Optional **min/max**: horizontal reference lines on bar/line charts, or a
    fixed scale on spider/radar charts shown as a small legend beside the figure.
  - **Legend hover** highlights the matching series (or pie slice). Line-chart
    tooltips attach to the dot under the cursor (showing every overlapping dot),
    and spider/radar points show a tooltip on hover too.
- **Custom theme colours** — every style-profile colour can be entered as a custom
  hex value in addition to the presets.
- **Per-slide TLP classification** — each slide can carry its own Traffic Light
  Protocol level; slides classified stricter than the level the deck is shown at
  are withheld when presenting and exporting.
- **Dual-screen presenter** — on a second display the beamer shows the slide
  while the laptop shows the presenter view (current/next slide, notes, timer),
  kept in sync over method channels.
- **Annotation layer** — draw on slides while presenting (pen, highlighter,
  eraser, laser pointer). Kept fully separate from the Marp Markdown, mirrored
  live to the beamer, and persisted in a `<name>.ink.json` sidecar.
- **App theming** — customizable app appearance profiles, including a dark
  interface.
- Project documentation: contributing guide, security policy, architecture and
  build notes, user guide, keyboard-shortcut reference, third-party notices, and
  the EUPL-1.2 licence text.

### Changed
- Slide transitions in the presenter no longer flash a black frame (neighbour
  images are precached and `gaplessPlayback` is enabled) — important for
  recording.

## [1.0.0]

### Added
- Initial release: structured, slide-by-slide editor for Marp presentations with
  typed slide templates, live preview, fullscreen presenter, deck-wide TLP
  marking, media handling, import, and export to Marp Markdown, PDF, PPTX, and
  self-contained HTML. Decks save as a self-contained project/package with copied
  assets. Localized in Dutch, English, Italian, German, French, Spanish, Frisian,
  and Papiamento.
