[v0.6.3] - 2026-04-28

Why Upgrade

• Native diff workflows are now available for comparing the current tab against disk and comparing two open tabs.
• iPhone and iPad toolbar/help surfaces are more discoverable, with a dedicated Toolbar Help entry and scrollable compact toolbars.
• Markdown Preview export is more reliable, including complete paginated PDF output and flexible one-page exports with tighter margins.
• Project sidebar actions on iPhone now open the expected file/folder pickers and keep new-file prompts stable.

Highlights

• Added a native side-by-side diff view with change navigation, accessible hunk summaries, Compare with Disk, and Compare Open Tabs entry points.
• Added a full Toolbar Help section that explains toolbar symbols, groups actions by workflow, adapts to iPhone/iPad/macOS widths, and is reachable from the toolbar, macOS Help menu, and menu-bar extra.
• Expanded iPhone/iPad toolbar coverage so commonly used and previously overflow-only actions are visible in the scrollable toolbar, with Toolbar Help pinned next to Settings on iPad.
• Updated the Welcome Tour with the latest major features and a live support-purchase card that avoids premature App Store price-unavailable states.
• Added .bak plain-text support and improved .zshrc/dotfile loading behavior.
• Improved Markdown language detection and Markdown syntax highlighting for task lists, tables, reference links, front matter, images, autolinks, block quotes, thematic breaks, comments, and metadata-style lines.
• Added the AMOLED Neon editor theme and tuned several neon/raw theme string colors for clearer contrast.
• Improved Markdown Preview typography on iPad and PDF export behavior for paginated and single-page output.

Fixes

• Fixed iOS Save File behavior so saving an existing file no longer behaves like Save As.
• Fixed iPhone project-sidebar toolbar buttons so Open File/Open Folder actions present the expected picker dialogs.
• Fixed iPhone project-sidebar new-file creation so the filename dialog no longer disappears immediately and the new tab is created.
• Fixed iPhone diff-view header sizing so Compare Local vs Disk labels wrap less aggressively on compact widths.
• Fixed Code Snapshot on iPhone to default to Wrap layout for new composer sessions.
• Fixed support-page and Welcome Tour support pricing so primary actions do not show Unavailable before StoreKit availability has been checked.
• Fixed one-page Markdown PDF export so a single page uses tighter margins and a flexible page length based on content.
• Fixed paginated Markdown PDF export so all pages include their full captured text content.
• Fixed Settings window close behavior on macOS.
• Fixed translucent-window line-number/theme readability regressions.

[v0.5.8] - 2026-03-28

Why Upgrade

• Huge files now reach first content faster through deferred, chunked installation instead of a single blocking editor handoff.
• Large-file sessions stay more responsive while the rest of the document is installed in the background.
• Large-file status is clearer while deferred loading is active, with visible session affordances for the active open mode.
• Remote workflows can now be started from the Mac, attached from iPhone and iPad, and used to browse, open, edit, and explicitly save supported remote text files through the Mac-hosted broker.
• Markdown preview export controls and the project sidebar now use a denser, more polished layout across macOS, iPhone, and iPad.

[v0.4.21] - 2026-02-16

Added

• Added curated popular editor themes: Dracula, One Dark Pro, Nord, Tokyo Night, and Gruvbox.

Improved

• Improved macOS self-hosted updater flow to download and verify releases in-app, then stage installation for background apply on app close/restart.
• Improved updater platform/channel safety by enforcing install actions only for direct-distribution macOS builds (never iOS/App Store).

Fixed

• Fixed Main Thread Checker violations in EditorTextView by ensuring NSTextView.string and selectedRange snapshot reads occur on the main thread.
• Fixed Neon Glow theme token mapping to match intended palette readability (dark gray comments, exact #003EFF string blue).

[v0.4.20] - 2026-02-16

Added

• Added iOS editor paste fallback handling that forces safe plain-text insertion when rich pasteboard content is unavailable or unreliable.

Fixed

• Fixed macOS line-number ruler behavior where line numbers could disappear near end-of-document when scrolling to the bottom.
• Fixed iOS line-number gutter sync at bottom scroll positions by clamping gutter content offset to valid bounds.

[v0.4.18] - 2026-02-15

Added

• Fixed macOS issue where moving focus away from the editor/window could temporarily drop syntax highlighting.

[v0.4.17] - 2026-02-15

Added

• Added translucency-toggle highlight refresh wiring so editor recoloring is explicitly re-triggered when window translucency changes.

Improved

• Improved syntax-highlighting stability during appearance/translucency transitions by forcing an immediate refresh instead of waiting for unrelated edits.

Fixed

• Fixed a macOS editor bug where toggling translucent window mode could temporarily hide syntax highlighting until another action (for example changing font size) forced a rehighlight.

[v0.4.16] - 2026-02-14

Added

• Added a release-doc synchronization gate to release_all.sh via prepare_release_docs.py --check so releases fail fast when docs are stale.
• Added a delegate-based updater download service that reports live progress into the update dialog.

Improved

• Improved updater install flow to stay user-driven/manual after verification, with Finder handoff instead of in-place app replacement.
• Improved editor appearance switching so base text colors are enforced immediately on light/dark mode changes across macOS and iOS.

Fixed

• Fixed light-mode editor base text color to consistently use dark text across themes.
• Fixed dark-mode editor base text color to consistently use light text across themes.

[v0.4.14] - 2026-02-14

Added

• Added centralized theme canonicalization with an explicit Custom option in settings so legacy/case-variant values resolve consistently across launches.
• Added a fallback GitHub Releases URL path in the updater dialog so View Releases always opens, even when no latest-release payload is cached.

Improved

• Improved macOS translucent-window rendering by enforcing unified toolbar style and full-size content behavior when translucency is enabled.
• Improved cross-platform theme application so iOS/macOS editor text + syntax colors respect the selected settings theme in both translucent and non-translucent modes.
• Improved iOS settings/action tint parity to use blue accent coloring consistent with macOS.

Fixed

• Fixed updater release-source validation regression that could block manual update checks in local/Xcode runs.
• Fixed toolbar/titlebar visual mismatch where toolbar areas rendered too opaque/white when translucency was enabled.
• Fixed settings theme-selection drift by normalizing persisted theme values and applying canonical names on read/write.

[v0.4.13] - 2026-02-14

Added

• Added scripts/run_selfhosted_notarized_release.sh helper to trigger/watch the self-hosted notarized release workflow and verify uploaded assets.

• Improved updater behavior in local Xcode/DerivedData runs by disabling automatic install/relaunch in development runtime.

Fixed

• Fixed update dialog failures caused by over-strict GitHub release-source path validation.
• Fixed startup reliability by removing eager Keychain token reads/migration on launch paths and treating missing-keychain datastore statuses as non-fatal token-missing cases.
• Fixed local debug key handling by using UserDefaults fallback in DEBUG builds to avoid blocking SecItemCopyMatching behavior during local runs.

[v0.4.12] - 2026-02-14

Added

• scripts/release_all.sh now accepts notarized as a positional alias, so scripts/release_all.sh v0.4.12 notarized works directly.

Improved

• Hosted notarized release workflow now enforces Xcode 17+ to preserve the Tahoe light/dark AppIcon.icon pipeline.
• Release asset verification now runs in strict iconstack mode to ensure published assets contain AppIcon.iconstack.

Fixed

• Settings window responsiveness on macOS by deferring/caching editor font list loading.

Fixed

• Reduced settings-open latency by removing forced full-window redraw calls during appearance application.

[v0.4.9] - 2026-02-13

Added

• Pre-release CI workflow on main/PR with critical runtime checks, docs validation, and icon payload verification.
• Release dry-run workflow and local scripts/release_dry_run.sh command for pre-tag validation.
• Release runtime policy test suite (ReleaseRuntimePolicyTests) covering settings-tab routing, theme mapping, find-next cursor behavior, and subscription button state logic.

Improved

• Unified release automation in scripts/release_all.sh to run preflight checks before tagging and to verify uploaded release assets after notarized publish.
• README changelog summary automation now keeps release summaries version-sorted and limited to the latest three entries.
• Notarized workflows now include compatibility fallbacks so older tags without scripts/ci/* can still be rebuilt and published.

Fixed

• Fixed macOS toolbar Settings (gear) button path to open the Settings scene reliably via SwiftUI openSettings.
• Hardened release workflows with post-publish verification and rollback behavior (delete bad asset and mark release draft on verification failure).

[v0.4.8] - 2026-02-12

Added

• Extended release automation coverage for the next tag cycle, including synchronized README/changelog/welcome-tour release content updates.

Improved

• Release pipeline guard failures caused by placeholder release notes (TODO) in the tag section.

[v0.4.7] - 2026-02-12

Added

• Indentation-based scope detection fallback for Python/YAML to render scoped-region and guide markers when bracket-only matching is not sufficient.
• Release workflow compatibility fallback for doc validation (grep-based checks), so release jobs no longer depend on rg being preinstalled on runners.

Improved

• Scope/bracket highlighting stability by dropping stale asynchronous highlight passes and applying only the latest generation.
• Visibility of matched bracket tokens and scope guide markers for easier detection on iOS and macOS.

Fixed

• Settings window opening/persistence path now uses the native Settings scene behavior, avoiding custom frame persistence conflicts.
• iOS appearance override handling for light/dark/system now applies consistently across app windows/scenes.

[v0.4.6] - 2026-02-12

Added

• Self-hosted notarized release workflow for macOS (release-notarized-selfhosted.yml) targeting macOS runners with Xcode 17+.

• Welcome Tour release page automation now derives the first card from the selected changelog section during release prep.
• Notarized workflow now validates toolchain requirements for icon-composer-based app icon assets.

Fixed

• Support purchase testing bypass is now hidden in distributed release builds (kept only for debug/simulator testing paths).
• Replaced deprecated receipt URL usage in support purchase gating with StoreKit transaction environment checks.
• Restored release icon source mapping to AppIcon.icon (dark/light icon pipeline) instead of using the fallback iOS icon set in release builds.

[v0.4.5] - 2026-02-11

Added

• Optional support purchase flow (StoreKit 2) with a dedicated Settings -> Support tab.
• Local StoreKit testing file (SupportOptional.storekit) and App Store review notes (docs/AppStoreReviewNotes.md).

• Consolidated macOS app icon source to a single Resources/AppIcon.icon catalog (removed duplicate Assets.xcassets/AppIcon.icon).

Fixed

• iOS build break caused by missing settings sheet state binding in ContentView.
• Find panel behavior (Cmd+F, initial focus, Enter-to-find-next) and highlight-current-line setting application.
• Line number ruler rendering overlap/flicker issues from previous fragment enumeration logic.
• Editor text sanitization paths around paste/tab/open flows to reduce injected visible whitespace glyph artifacts.
• Prevented reintroduced whitespace/control glyph artifacts (U+2581, U+2400–U+243F) during typing/paste by hardening sanitizer checks in editor update paths.
• macOS line-number gutter redraw/background mismatch so the ruler keeps the same window/editor tone without white striping.
