Changelog

All notable changes to this project will be documented in this file.

[Unreleased]

[0.6.3] - 2026-02-13

Changed

  • Cached search-highlighted lines so unchanged redraws reuse prior highlighted output instead of re-running regex highlighting across the whole document.

[0.6.2] - 2026-02-13

Changed

  • Moved local image dimension probing off the UI thread during load/reload by sending probe jobs to the background image worker.
  • Removed per-frame document line cloning before paragraph rendering by transferring ownership of display lines into Text.
  • Kept scrolling/input responsive while images load by throttling image-load result processing per UI tick.
  • Moved image resize/encode work off the UI thread into a dedicated background resize worker so rendering large images no longer blocks navigation.

[0.6.1] - 2026-02-13

Changed

  • Cached virtual-row counts in max_scroll keyed by content width, with invalidation on reload, search-state changes, and image layout updates to avoid rebuilding the full display document on frequent navigation/redraw paths.

[0.6.0] - 2026-02-11

Added

  • Less-style half-page navigation aliases: d (down) and u (up), in addition to Ctrl-d / Ctrl-u (issue #1).

[0.5.0] - 2026-02-10

Added

  • Lazy image loading with non-blocking background fetch/decode so markdown opens immediately.

Changed

  • Image layout now reserves space before load using HTML <img width height> hints when available.
  • Images without explicit dimensions use a default placeholder estimate during lazy loading.
  • Improved image rendering stability while scrolling past images by fixing partial-viewport draw artifacts and distortion.
  • Long image source captions are truncated in display text to reduce wrap bleed in the viewport.

[0.4.0] - 2026-02-10

Added

  • Visible in-document cursor with line:column cursor position in the status bar for easier eye tracking.

[0.3.0] - 2026-02-10

Added

  • Syntax highlighting for fenced code blocks with recognized language tags.

[0.2.0] - 2026-02-10

Added

  • Inline terminal image rendering for markdown images and HTML <img ...> tags.
  • Remote image loading for http:// and https:// image URLs.
  • --image-protocol CLI option to force a specific image backend (auto, halfblocks, sixel, kitty, iterm2).

Changed

  • Markdown image tokens now include visual fallback caption lines when an image cannot be loaded.
  • TUI redraw loop now renders on input/resize state changes instead of a fixed idle cadence to reduce flicker while scrolling.

[0.1.0] - 2026-02-10

Added

  • Vim-style full-page navigation with Ctrl-f (down) and Ctrl-b (up).
  • Visual highlighting for search matches in the document view, with stronger emphasis on the active match.

Changed

  • Renamed the CLI and package from mdview to mdvi.
  • Updated in-app title/help text and README command examples to use mdvi.
  • Search matches are rebuilt after file reload so navigation and highlights stay accurate.
