• We’ve fixed paragraph breaks in content copied from previews so that they paste correctly. • We’ve reduced the size of image placeholders and changed the colour of referenced paths to better imply the error condition the use of placeholders represents.

• Fully support the public.markdown UTI. • Fix an issue with the warning shown when the feedback character-limit is exceeded. • Under the hood improvements.

• Opposites (optionally) attract. Previously if your Mac was in Dark Mode, you could choose to have previews rendered in Light Mode nonetheless. We’ve updated PreviewMarkdown so the same setting now also presents previews in Dark Mode even if your Mac is set to Light Mode. In other words, whatever mode your Mac is set to, previews are presented in the opposite way. Or just turn keep the setting switched off to have previews match your Mac’s current mode. • Improved error checking in certain cases will hopefully mean fewer thumbnailer crashes. • Fix truncation of feedback text to prevent loss of styling. • Reminder: PreviewMarkdown no longer supports macOS 10.15 Catalina, and we will be ending macOS 11 Big Sur support in a forthcoming release.

• Correct the colour of the preview scrollbar in light mode.

• We’ve added some extra settings: ° Control preview window size: small (42% of main screen; standard QuickLook size), medium (50% of main screen) or large (75% of main screen) ° Set your preferred preview whitespace margin. ° Set all Markdown file thumbnails to match Finder’s display mode under macOS 26.1+. • We’ve added new, more intuitive graphic for unchecked checkboxes. • We’ve fixed some reported bugs: ° Front matter detection now works correctly when horizontal rules are also included in the Markdown. ° Image URLs are no longer converted to lower case.

• Restore PreviewMarkdown’s dark-on-white thumbnails that were made modal by macOS 26.1. • Correct preview background colour in light mode. • Correct the link to the app’s help content.

• We’ve improved the clarity of code snippets when they’re viewed in light mode. We’d like to thank the users who raised this as an issue with us.

• Tahoe support phase II: adjust PreviewMarkdown’s Settings UI for the new design style.

• Welcome, macOS 26. We’ve started to support you with a new glassy icon and menu icons.

• The PreviewMarkdown 2 facelift continues with a new, proportionally-spaced-text friendly YAML front matter design. • We’ve figured out how to twist QuickLook’s arm to present a much larger preview window, sized for the screen you’re working on. • We’ve added a second macOS system-wide text service: Convert Markdown Text to Plain Text. • We’ve made one further, but small UI change: see if you spot what it is.

• As requested by a number of users, you can now opt to add a narrow whitespace margin area around the preview so the text doesn’t run right up to the edge of the window. • Also as requested by a number of users, you can now specify the colour of YAML keys that are displayed in previews when you have front-matter rendering enabled. This is paving the way for a major change to the way PreviewMarkdown presents YAML frontmatter. 'nuff said. • Improved some of the main application’s graphic design. • Squashed a couple of bugs. • Applied some under-the-hood jiggery-pokery.

• Completely new rendering engine, designed from the ground up with: • Markdown table support. • Code highlighting for fenced code blocks (provided language is known) • Numbered lists can be started with any value • Numbered and unordered lists can have any depth. • Numbered and unordered lists containing blockquotes, code and/or multi-paragraph text are presented more neatly. • Fuller set of escaped characters supported. • Preliminary image support. • A new tab-based UI for the host application for fast access to key features. • Add a 'Convert Markdown Text to HTML' system-wide text service.

• Improve settings change checking. • Correctly render the YAML front matter separator line. • Under-the-hood improvements.

• Revise thumbnailer to improve memory utilization and efficiency.

• Support the emerging ‘public.markdown’ UTI. • Support YAML front matter that uses the ‘...’ end marker (Thanks, anonymous). • Better ‘What’s New’ dialog presentation in dark mode.

• Add line-spacing setting for previews. • Add link on the Preferences pane to help. • Add experimental Finder UTI database reset option. • Rename extensions Markdown Previewer and Markdown Thumbnailer. • Improve font edge-case handling. • Remove dynamic UTIs.

• Add link to PreviewText. • Better menu handling when panels are visible. • Better app exit management. • Bug fixes.

• Add the com.nutstore.down Markdown UTI.

* Add link to PreviewJson * Internal updates and fixes.

• Initial support for non-utf8 source code file encodings.

• Add support for GitHub-style Markdown checkboxes. • Minor internal tweaks.

• Disable selection of thumbnail tags under macOS 12 Monterey to avoid clash with system-added tags.

• You can now select any installed monospace font for code blocks. • You can now select any installed proportional font for text. • You can now choose a separate colour for preview headings. • You can now choose any colour using the standard macOS colour picker. • Improve thumbnail rendering code. • Fixed a rare bug in the previewer error reporting code

• Add links to other PreviewApps. • Support macOS 11 Big Sur’s UTType API. • Stability improvements.

• Previews can now optionally include YAML front matter. • Fixed an issue that caused generic thumbnails to appear occasionally. • Other code improvements.
