Changelog

The first release since 0.8.0-alpha. It also contains every change listed
under
0.9.0,
which was never released on its own. Requires macOS 27 on Apple silicon.

Added

• Apple Intelligence as an AI provider. Presets can run on the
  on-device model: no key, nothing leaves the Mac. Settings ▸ AI shows
  whether it's ready, the model (e.g. "AFM 3 Core Advanced") and its
  context size, and offers System Settings when it's turned off. The
  context is small (8,192 tokens on recent Macs), so a selection that
  doesn't fit is refused before anything runs, with a pointer to
  Anthropic or OpenAI. New installs default to Apple Intelligence when
  it's available, else to Anthropic.

• Custom providers. Add any number of OpenAI-compatible servers
  (Ollama, LM Studio, vLLM, on this Mac or another one) in Settings ▸ AI
  with a name, base URL, model and an optional API key (kept in the
  Keychain), and choose one as the default provider.

• Settings, redesigned: four panes, General, Appearance, Editor and
  AI. Every earlier option is still there; your saved look stays as it
  was.

  • Appearance (Automatic / Light / Dark) for the window chrome. The
    editor page keeps its own background colour.
  • Custom colours: a fifth background swatch with your own text and
    background colour; code blocks, rules and muted text are derived
    from the pair.
  • Font: SF Pro, SF Mono, New York or any installed family (Other…
    opens the font panel).
  • Line width: Readable (about 66 characters of the body font),
    Wide (100) or Full. New installs use Readable, existing settings
    keep Full.
  • Card layout is its own switch (Settings ▸ Editor). It used to
    come only with the Tahoe preset, which still turns it on.
  • General: show the welcome window on launch, check for updates
    automatically, reveal keybindings.json.

• macOS 27 window. The outline runs edge to edge down the left side
  with the system's sidebar button (View ▸ Show Outline, ⌃⌘S). One
  toolbar shows the document name, Share and the inspector button.
  Share sends the Markdown file. An untitled document, or one with
  unsaved edits, is shared as a temporary .md of the current text.

• Inspector (View ▸ Show Inspector, ⌥⌘I, closed when a window
  opens): the front matter's title, tags and date; words, characters,
  lines, reading time and headings; where the file lives, when it was
  modified and its format.

• Editable front matter fields. Title, Tags (chips: × on hover or
  right-click to remove, "Add…" to add) and Date write back into the
  YAML when you press Return or leave the field, as one undo step
  (Edit ▸ Undo Edit Title). Only the edited key's line changes: other
  keys, comments, order, quoting and list style stay as they were, CRLF
  files keep CRLF. A document without front matter gets a block at the
  top on the first entry; clearing a field removes its key. The date
  shows as "October 3, 2026" and as written while you edit it.

• Front matter collapses to one grey line at the top of the editor
  ("October 3, 2026 · travel, portugal"; the title is added when it
  differs from the first heading). Put the caret into it (arrow up,
  click) to see and edit the raw YAML; it collapses again when the
  caret leaves. The file is not changed. A document opens with the
  caret below the front matter; Backspace there opens the block
  instead of deleting its hidden last line break.

• Word count in the editor's bottom-right corner ("412 words"),
  replacing the status bar. It counts the words you read: no Markdown
  markers, front matter, code or math blocks, list bullets and numbers,
  footnote labels or table pipes.

• File ▸ New Tab (⌘T) opens a new document as a tab of the front
  window. ⌘N follows System Settings ▸ Desktop & Dock ▸ Prefer tabs.

• Find options menu behind the magnifier in the find field: Ignore
  Case, Wrap Around, Contains / Starts With / Whole Word, Regular
  Expression, Ignore Markdown Formatting. Wrap Around off stops at
  the first and last match with a beep; Starts With finds matches
  at the start of a word. The choice is remembered and applies to
  every window.

• ⌘G / ⇧⌘G with the find bar closed search again for the last
  query and select the match, as in other Mac apps. ⌘E also puts the
  selection on the system find pasteboard, and an empty find bar starts
  with the string another app put there.

• A space in the query also matches a line break inside a paragraph,
  so "tram out" finds a hard-wrapped tram⏎out (what Reflow shows as
  one line). A blank line still ends the match.

• Format menu between Edit and View: Heading 1–3 (⌘1–⌘3), Body
  (⌘0), Bold (⌘B), Italic (⌘I), Strikethrough, Inline Code, Link… (⌘K),
  Checklist, Quote, Table, Move Line Up/Down (⌥⌘↑/↓), Duplicate Line
  (⇧⌘D). Each is one undo step named after it.

  • Bold, Italic, Strikethrough and Inline Code work on the selection or
    the word at the caret and take the markers off again when the text
    already has them (also when they sit just outside the selection, or
    the caret is anywhere in the styled span). A selection over several
    styled spans takes each span's markers off. Over several lines each
    line is styled on its own, after its bullet, checkbox, > or #.
  • Link… asks for the address, prefilled with a URL on the clipboard;
    inside a link it changes the address or removes the link.
  • Checklist turns lines (and -/1. list items) into - [ ] tasks
    and back; Quote adds or removes > ; Table inserts a three-column
    table after the selection and selects its first header.
  • New keybindings.json names: bold, italic, strikethrough,
    inlineCode, link, checklist, quote, table. A rebinding
    also moves the shortcut shown in the menu. Heading 4–6 (⌘4–⌘6) and
    Select Line (⌘L) stay key bindings and are in the command palette.

• View menu: Show Outline (⌃⌘S), Show Inspector (⌥⌘I) and Show Word
  Count with checkmarks; Focus Mode (⌃⌘F), Typewriter Mode (⌃⌘Y),
  Reflow Mode (⌃⌘R); Command Palette… (⇧⌘P).

Changed

• Requires macOS 27 or later (0.8.0-alpha ran on macOS 14). Macs on
  macOS 14 to 26 stay on 0.8.0-alpha; the update is not offered to them.
• The starter AI presets have English names (Clean Up Markdown,
  Summarize, Rewrite Naturally …) on new installs and after Reset.
  Presets you already have keep their names.
• New app icon: three lines of paper, the middle one raw Markdown
  with a blue # and the caret.
• Quick Look previews Markdown files only; plain text files keep the
  system's own preview. It reads the same encodings PicaMD opens
  (UTF-16, Windows 1252, ISO Latin-1), not only UTF-8.
• The outline uses the system sidebar colours and highlights the
  current heading in your accent colour. The bar of front matter above
  the editor is gone; its fields are in the inspector.
• Windows open at 1100 × 750 and can't get narrower than 820 pt, so
  outline, editor and inspector always fit.
• Default models: Anthropic claude-sonnet-5-5 (was
  claude-sonnet-4-6), OpenAI gpt-6-luna (was gpt-4o-mini). Saved
  settings that still had an old default move along; a model you chose
  yourself stays.
• New installs start with SF Pro as the body font (was SF Mono).
• "Show status bar" is now "Show word count" (Settings ▸ Editor); the
  stored choice carries over.
• AI: an Anthropic refusal shows the reason the API gives. Settings ▸ AI
  is one grouped form with providers, custom providers and presets.
• Find bar, redesigned: docked under the toolbar across the editor
  column and pushing the text down, instead of a card floating over it.
  "2 of 3" sits inside the search field, ‹ › and Done beside it;
  Replace, Replace and All below in Find and Replace mode. Shift-Return
  goes to the previous match. Replace and All are disabled, with a
  tooltip saying why, while Ignore Markdown Formatting is on.
• Find matches are system yellow instead of the accent colour; the
  current match is solid yellow with dark text and a thin outline.
• Command palette, redesigned: a panel floating over the window
  instead of a sheet. It lists only what matches what you type, under
  "Headings" ("Heading 2 · line 4") and "Commands" with their shortcuts:
  every View and Format command, Find, Export, Settings (also straight to
  one pane) and, while AI is on, the AI presets. Arrow keys move,
  Return runs, Esc or a click outside closes it, ⇧⌘P again too. The
  selection is filled with your accent colour.
• Welcome window, redesigned (800 × 500): app icon, name and version
  on the left with New Document and Open… cards and the "Show this window
  when PicaMD opens" checkbox (the same setting as Settings ▸ General);
  recent documents on the right with their folder ("Documents ▸ Travel",
  "iCloud Drive", "OneDrive"), the first one selected in
  your accent colour. Arrow keys move, Return opens, a click opens.
  Right-click a recent for Show in Finder, Remove from Recents and Clear
  Recents. Follows light and dark mode.
• Launch: with "Show this window when PicaMD op...
