What’s New Since v0.5.2

Who Is This For?

Why This Instead of a Full IDE?

Who This Is Not For

Download

Prebuilt binaries are available on GitHub Releases.

GitHub Releases (Stable)

Best for direct notarized builds and fastest access to new stable versions.

App Store

Best for users who prefer Apple-managed installs and updates.

TestFlight (Beta)

Best for testing upcoming changes before they land in the stable channel.

Install

Quick install (curl)

Install the latest release directly:

curl -fsSL https://raw.githubusercontent.com/h3pdesign/Neon-Vision-Editor/main/scripts/install.sh | sh

Install without admin password prompts (user-local app folder):

curl -fsSL https://raw.githubusercontent.com/h3pdesign/Neon-Vision-Editor/main/scripts/install.sh | sh -s -- --appdir "$HOME/Applications"

Homebrew

brew tap h3pdesign/tap
brew install --cask neon-vision-editor

Tap repository: h3pdesign/homebrew-tap

If Homebrew asks for an admin password, it is usually because casks install into /Applications. Use this to avoid that:

brew install --cask --appdir="$HOME/Applications" neon-vision-editor

Gatekeeper (macOS 26 Tahoe)

If macOS blocks first launch:

  1. Open System Settings.
  2. Go to Privacy & Security.
  3. In Security, find the blocked app message.
  4. Click Open Anyway.
  5. Confirm the dialog.

Architecture principles

Platform Matrix

Most editor features are shared across macOS, iOS, and iPadOS.

Shared Across All Platforms

Platform-Specific Differences

Capability macOS iOS iPadOS Notes
Quick Open
Cmd+P		 Full Limit Full iOS needs a hardware keyboard
for shortcut-driven flow.
Bracket Helper Toolbar Kbd Bar Kbd Bar Same behavior across platforms;
only the UI surface differs.
Markdown Preview Inline Sheet Inline Interaction adapts to screen size
and platform input model.

Next (v0.5.5 - v0.5.7)

Later (v0.6.0)

Known Issues

Troubleshooting

  1. App blocked on first launch: use Gatekeeper steps above in Privacy & Security.
  2. Markdown preview not visible: ensure you are on macOS or iPadOS (not available on iPhone).
  3. Shortcut not working on iOS: connect a hardware keyboard for shortcut-based flows like Cmd+P.
  4. Sidebar/layout feels cramped on iPad: switch orientation or close side panels before preview.
  5. Settings feel off after updates: quit/relaunch app and verify current release version in Settings.

Version Date Highlights Fixes Breaking changes Migration
v0.5.3 2026-03-10 a new high-readability colorful light theme preset: Prism Daylight (also selectable while app appearance is set to dark); double-click-to-close behavior for tabs on macOS tab strips; custom theme vibrancy by applying the vivid neon syntax profile to Custom, so syntax colors remain bright and saturated toolbar-symbol contrast edge cases in dark mode where gray/black variants could appear too similar None noted None required
v0.5.2 2026-03-09 editor performance presets in Settings (Balanced, Large Files, Battery) with shared runtime mapping; configurable project navigator placement (Left/Right) for project-structure sidebar layout; iOS/iPadOS large-file responsiveness by lowering automatic large-file thresholds and applying preset-based tuning missing diagnostics reset workflow by adding a dedicated Clear Diagnostics action that also clears file-open timing snapshots; macOS editor-window top-bar jumping when toggling the toolbar translucency control by keeping chrome flags stable; CSV/TSV mode header transparency so the mode bar now uses a solid standard window background None noted None required
v0.5.1 2026-03-08 bulk Close All Tabs actions to toolbar surfaces (macOS, iOS, iPadOS), including a confirmation step before closing; project-structure quick actions to expand all folders or collapse all folders in one step; Markdown preview stability by preserving relative scroll position during preview refreshes diagnostics export safety by redacting token-like updater status fragments before copying; Markdown regression coverage with new tests for Claude-style mixed-content Markdown and code-fence matching behavior; accidental destructive tab-bulk-close behavior by requiring explicit user confirmation before closing all tabs None noted None required
