Releases

No user-facing changes — the app behaves exactly as 1.0.4.

Changed

• The complete corresponding source for this release is published.
• The Gradle distribution is pinned by SHA-256 checksum, so the build verifies the contents of the toolchain it downloads and not only its URL — a prerequisite for reproducible builds.
• Store listing metadata is now tracked in the repository alongside the source.

Added

• Footnotes — [^1] references and [^1]: … definitions now render, with tap-to-jump and a link back to the reference. Definitions render in place; references renumber 1..n by first use.
• Plain text files — .txt files open in the reader, with a per-file long-line overflow toggle.
• Chemistry formulas — \ce{…} (mhchem) notation renders inside math.

Fixed

• A long-standing freeze when opening large files. Line-ending detection scanned the document twice with a regex on the main thread, which degraded quadratically — a 1.3 MB file could block the app for tens of seconds and a 3 MB file for minutes. Detection is now a single linear pass off the main thread. Present since 1.0.0.
• A crash when entering the editor on some devices, caused by the shared editor view being re-attached while still parented.
• Inline code and raw HTML were silently dropped inside table cells in every previous release. Table cell rendering now recurses into unrecognised nodes by default rather than discarding them.
• Search match counts in documents containing math no longer over-count.

Build metadata removed from the APK so F-Droid can reproduce the build byte-for-byte. No functional changes.

Fixed

• An unrenderable paragraph no longer takes the whole document down. One rendering path was missing the guard the others had, so a single paragraph that failed to render could bring down the reader instead of just itself. It now shows a short placeholder in place of that paragraph and the rest of the document renders normally.

Changed

• Crash reports from the store now arrive with readable stack traces. Build-only change: the app’s behaviour, size and performance are unchanged.

Added

• Inline math with single dollars — $…$ now renders inline LaTeX alongside the existing $$…$$ form (currency-aware, so $5 and $10 stays plain text).
• Save As — save the open document to a new location, including brand-new documents that don’t have a file on disk yet.
• Branded launch splash — a brand-dark splash screen in both light and dark appearances.
• Pinch-to-zoom in the reader — live text reflow anchored at the gesture focal point, kept in sync with the Settings text size.
• Clear-Recents confirmation — clearing the Recents list now asks first.
• GitHub-integration teaser in Settings — a roadmap note with an email interest link. It only opens your email app; nothing is sent unless you tap send.
• Crash-recovery escape hatch — if recovered unsaved changes can never be committed back to the original file, the app now offers a way out instead of blocking the document forever.

Fixed

• In-document search counts matches in the rendered text, and the reader makes room for the keyboard while searching.
• The close-without-saving confirmation dialog now survives device rotation.
• Back navigates within the app instead of exiting it.
• The file picker soft-filters to Markdown files, and its Browse-all fallback makes every file selectable.
• Status and navigation bars follow the app theme, so their icons stay legible in the light theme.
• The active Reader/Editor mode is unmistakable in the toolbar (accent chip on the active side).

The first release: the initial v1 feature set.

Added

• Native Markdown reader — GitHub-Flavored Markdown rendered to native Android views (no WebView): headings, lists, task lists, tables, blockquotes, code blocks with syntax highlighting, links, and images-as-alt-text on the offline path.
• LaTeX math rendering (inline and block) and opt-in cloud Mermaid diagrams (off by default; degrades to a code block when disabled or unavailable).
• YAML frontmatter shown as a metadata card rather than a raw code block.
• Editor built on the Sora editor with Markdown syntax awareness.
• PDF export of the rendered document, including long-line wrapping for code.
• Table of contents drawer that jumps to headings.
• Settings: font sets (Source Serif 4 / JetBrains Mono), separate reader/editor zoom, theme, and the optional Mermaid toggle.
• Storage Access Framework integration for scoped, user-granted file access.
• Dark and light themes driven entirely by a design-token layer.

Safeguards

• Atomic saves — a failed save aborts cleanly and never leaves a truncated or corrupted file.
• Round-trip fidelity — saving writes back exactly what you wrote; line endings (LF/CRLF) and frontmatter are preserved, with one documented bound: a file with mixed line endings is written back uniformly in its dominant style.
• Crash-resistant rendering — unsupported or malformed syntax degrades gracefully instead of throwing or mangling surrounding content.

Privacy

• No accounts, analytics, ads, or telemetry. The reading path makes no network requests by default; cloud Mermaid rendering is the only optional networked feature and is off by default.
