Markdown Midget v0.4.0-beta1

Minor bump to 0.4.0. Two user-visible wins — documents that reference images
now render them fully, and the recurring "editor surface couldn't load"
(ERR_ACCESS_DENIED) crash after a hard exit is fixed — plus safe rendering of
embedded raw HTML. Shipped as a beta for a weekend of dogfooding before the
prerelease flag is dropped for 0.4.0 stable.

Added

• Crash-resilient WebView2 profile. Each run now uses its own per-process
  WebView2 data folder instead of one shared folder. A hard crash or force-kill
  used to orphan WebView2 child processes that kept the shared folder locked,
  breaking the next launch with ERR_ACCESS_DENIED; per-process folders can't
  collide, so the following launch is always clean (stale folders from prior runs
  are swept on startup, skipping any still in use). If the editor surface still
  fails to load, the app offers a one-click restart into a fresh profile rather
  than stranding the user on a cryptic Edge error page. Documents and settings are
  untouched.
• Raw HTML now renders (sanitized). Embedded HTML — a centered logo
  (<p align="center"><img …>), <br>, <sub>/<sup>, small tables, etc. —
  renders instead of showing as escaped text. The HTML is sanitized with
  DOMPurify (scripts, event handlers like onerror, iframe/object, and
  javascript: URLs are stripped) before display, and the original markup is
  kept in the model so saving round-trips it unchanged. Relative image paths
  inside the HTML resolve against the document folder like everything else.

Fixed

• Relative image paths in opened files now render. Images referenced
  relative to the document (e.g. docs/logo.png) resolve against the file's
  folder — the way Markdown Monster and GitHub do. A <base href> points at a
  dedicated host whose files the app serves from the document's folder via
  WebResourceRequested (a second virtual-host mapping won't serve cross-origin
  to the editor host, and image bytes weren't delivered). Only URL resolution
  changes; the markdown keeps the original relative paths, so saving is
  unaffected. Serving is restricted to the document's own folder subtree;
  untitled / dropped content clears the base. (Images inside raw HTML — e.g. a
  centered logo — render too; see "Raw HTML now renders" above.)

Download

MarkdownMidget-v0.4.0-beta1-win-x64-net10.exe — single-file, framework-dependent build (~6.15 MB).

Requirements

• Windows 10/11 (x64)
• .NET 10 Desktop Runtime — https://dotnet.microsoft.com/download/dotnet/10.0
• Microsoft Edge WebView2 Runtime — preinstalled on Windows 11; otherwise a free download from Microsoft.

Notes

• The download is signed by Funcular Labs via Azure Artifact Signing (Authenticode). If Windows SmartScreen warns on a very new release, the reputation graph builds up quickly for signed installers.
• Settings/recent files live under %LocalAppData%\MarkdownMidget.

Markdown Midget v0.3.0-beta1

First 0.3.0 release (the alpha1 work was dogfooded internally, never published,
and is rolled up here).

Added

• Richer Register / Unregister dialogs for Windows integration, each with
  minimalist diagrams so non-technical users can see what every option does.
  • Register (all on by default): Move the download into the app folder
    (vs. copy), Add to Start menu, Add a Desktop shortcut, plus the
    existing Set as default. The original download location is remembered.
  • Unregister (all optional): remove the Open With registration, restore a
    copy to where it was downloaded, remove the Start-menu entry, remove the
    Desktop shortcut, and remove the installed app-folder copy.
  • Move installs to the app folder then relaunches from there and deletes
    the original download (via a --finish-move handoff, guarded by the
    unsaved-changes prompt so a restart can't drop edits).
• Skip Spell Check in Code (View menu, WYSIWYG) — leaves code blocks and
  inline code un-checked while still spell-checking prose, so identifiers,
  keywords and snippets don't get flagged. On by default; remembered between
  sessions. (Source view remains all-or-nothing — a WPF TextBox limitation.)
• Spell-check on/off is now remembered between sessions.
• ROADMAP.md — a living wishlist/roadmap. First entry: the
  de-risk spike for owning the spell-check stack (custom dictionaries +
  "Add to dictionary" via the Windows Spell Checking API), since WebView2
  exposes no dictionary API.

Changed

• Denser table styling. Square corners, a gray header row (darker than the
  stripes), tighter cell padding (1px 6px), 12px text, and the first data row
  is light (stripes start on row 2). Also fixed a latent bug where Nord's
  !important logical-padding rules were silently overriding our cell padding —
  tables now render at the intended density.

Fixed

• Win+arrow window management now behaves like Notepad / File Explorer. We
  were intercepting Win+arrow and hand-rolling snap math, which was worse than
  the OS (no snap-assist, poor multi-monitor/DPI handling). Removed the handler
  entirely; the window is a standard resizable window, so native Windows Snap
  just works.

Markdown Midget v0.2.0-beta2

Added

• Authenticode-signed releases via Azure Artifact Signing. The release
  workflow now signs the published exe using a service principal + the
  funcular-labs-public-trust certificate profile, then verifies the
  signature before uploading to the release. Windows SmartScreen will build
  reputation quickly for signed installers rather than warning on every run.

Changed

• Exe metadata is populated. Details tab now shows Company (Funcular Labs),
  Copyright (© Funcular Labs 2026, MIT), Product / FileDescription
  (Markdown Midget with the space), and the +git-sha suffix that MSBuild
  was appending to ProductVersion is suppressed.
• AppVersion is now derived from the assembly's
  AssemblyInformationalVersionAttribute at runtime. CI passes
  -p:InformationalVersion=<tag-version> at publish, so the title-bar version
  automatically reflects whatever tag drove the release — no more manual const
  bumps between the code, the csproj, and the tag.

Markdown Midget v0.2.0-beta1

Beta milestone. Everything from the 0.1.x alpha series is baked in and the
release engineering (CI, tag-driven publishing, unit tests, embedded HELP.md,
Windows integration) is proven. This is the first -beta — targeted at
hands-on testing before dropping the prerelease flag for 0.2.0 stable.

Changed

• README image references now point at
  raw.githubusercontent.com/…/master/art/… instead of relative paths, so the
  file renders identically on GitHub and stays functional when the README is
  copied anywhere (the absolute URL always resolves, without falling into the
  GitHub-strips-data-URIs trap).
• Refreshed screenshot — updated to reflect the current 0.2 feature set
  (formatting marks toggled on, live table editing, syntax-highlighted code
  block, ¶ tab-arrow marks, custom spell-check icon on the View toolbar,
  in-document mascot).

Markdown Midget v0.1.8-alpha3

Added

• Unit tests. New tests/MarkdownMidget.Tests/ xUnit project covering
  FindEngine (four search modes, escapes, wildcards, whole word, case, regex
  edge cases) — 32 tests, ~40 ms locally.
• GitHub Actions CI: .github/workflows/ci.yml runs on pushes to master
  and every PR — builds the editor bundle (npm) + solution + runs tests on
  windows-latest with .NET 10.
• GitHub Actions release publishing: .github/workflows/release.yml fires
  on v* tag pushes. Builds the editor bundle, runs tests, publishes the
  framework-dependent exe with tag-derived Version / InformationalVersion,
  extracts the matching CHANGELOG section for release notes, appends the
  standard Download / Requirements / Notes boilerplate, and creates the
  GitHub release (prerelease flag inferred from -alpha/-beta/-rc in
  the tag). This release is the first published by CI.
• README and HELP.md now embed all images as base64 data URIs so the
  files stay self-contained if copied outside the repo tree. HELP.md's
  mascot header set the pattern in alpha3-prep; the README screenshot and
  mascot follow the same convention.

Markdown Midget v0.1.8-alpha2

Fixed

• Registration dedupe now covers the per-user Explorer ProgID MRU. The 0.1.8-alpha1 dedupe cleaned HKCU\Classes\.md\OpenWithProgids and the OpenWithList MRU but missed the parallel per-user Explorer\FileExts\.md\OpenWithProgids layer — that's what was letting a stale "Markdown Midget" reference to an older version survive re-registration. Also handles legacy Applications\MarkdownMidget… / Applications\mkm… ProgID references in the same MRU and clears an outdated UserChoice if it points at one of ours.
• The "Set as default" prompt now walks the user through Settings. Windows 10/11 protect the default-app UserChoice hash so apps can't set defaults programmatically; the registration confirmation now spells out exactly what to click in the Settings pane that gets opened.
• Registration success message notes that Explorer's Open With submenu aggressively caches and may still show an old entry until sign-out.

Added

• F1 opens the Help window (in addition to Help ▸ View Help). The menu item displays the shortcut.

Markdown Midget v0.1.8-alpha1

Added

• File ▸ Windows Integration ▸ Register as .md editor… — a per-user, no-admin workflow to add Markdown Midget to the Windows "Open with" menu for .md files. Uses a stable ProgID (MarkdownMidget.Document), so re-registering the current version overwrites the same registry key and can't accidentally create duplicates. On register we also dedupe stale references to Markdown Midget (previous "Choose another app" pickings under FileExts\.md\OpenWithList, old Applications\ entries under different exe filenames like mkm.exe).
• Optional AppData install + Start-menu entry. Checkbox in the register dialog copies the current build to %LocalAppData%\Programs\MarkdownMidget\MarkdownMidget.exe and creates a Start-menu shortcut — a portable-app style install with no MSI. Recommended because it keeps the Open With entry stable across future releases (just re-register after each upgrade).
• Optional "Set as default" — Windows 10/11 protect the UserChoice hash so apps can't set defaults programmatically; the checkbox opens the Default Apps Settings page filtered to .md for the user to confirm with one click.
• File ▸ Windows Integration ▸ Unregister as .md editor — removes the ProgID + Applications entry + .md\OpenWithProgids link and does the same dedupe pass. If an AppData install exists (and isn't the currently-running copy), asks whether to also remove that folder and the Start-menu shortcut.

Markdown Midget v0.1.7-alpha2

Fixed

• Find Next / Find Previous now actually advance the cursor. The WYSIWYG dispatcher was calling findReset() on every navigation, which reset the match pointer to -1 — so F3 always landed back at the first match. The reset is now only performed when the pattern or its options change (and is invalidated on any subsequent document edit).
• Find no longer "lands nowhere" when a match falls inside a hidden mermaid source block. The text-node walker now rejects any node whose ancestor has display: none or visibility: hidden (which covers the hidden mermaid <pre>, collapsed details, draft regions, etc.).

Added

• Standard Windows window-management shortcuts, intercepted at the WPF Window so they work even when the WebView2 child has keyboard focus:
  • Win+Up — maximize (restore-from-minimized if minimized)
  • Win+Down — minimize (restore-from-maximized if maximized)
  • Win+Shift+Up — fill the working-area height at the current width
  • Win+Left / Win+Right — snap to the left / right half of the work area

Markdown Midget v0.1.7-alpha1

Added

• Find (Edit ▸ Find… / Ctrl+F) — modeless dialog with four search modes (Normal, Extended, Wildcards, Regular expression), Match case / Match whole word only / Wrap around toggles, and a Match m of n status line. F3 jumps to the next match, Shift+F3 to the previous. Find works in both the WYSIWYG view (text-node scan with browser-selection highlight) and the Markdown source view (TextBox selection). Tooltips on the Extended / Wildcards / Regex radios describe the syntax. HELP.md has the full escape tables. Replace is not yet in; this iteration is read-only Find.
• Spinner overlay when opening a file — a small busy card shows over the editing area during the read + editor load, useful for large documents with embedded base64 images. Fires on File ▸ Open, Open Recent, and editor-area file drops.

Markdown Midget v0.1.6-alpha1

Added

• Mermaid diagrams. Fenced code blocks tagged mermaid now render as live diagrams in the WYSIWYG view (flowcharts, sequence diagrams, class diagrams, etc.). The diagram appears below the block, the source itself is hidden while the cursor is outside the block, and revealed for inline editing when the cursor moves into it. Markdown round-trips unchanged (the on-disk file remains a normal ```mermaid fence). Print and PDF export render the diagram (not the source), with page-break-inside avoided.

Known limitations

• Mermaid pulls a large dependency tree (D3, dagre, cytoscape) — the editor bundle grows from ~560 KB to ~3.9 MB. The extracted bundle is one-time-per-run and cached by WebView2 thereafter; the app's startup time is still well under a second on a typical machine, but the on-disk .exe size grows by about 3.5 MB after compression. Bundle splitting / lazy-load is a possible later optimization if this becomes a concern.
