Release Notes

Performance: Native Rust Core

This release rewrites the core data processing layer in Rust (via N-API), delivering significant performance improvements across the board.

The following modules have been moved from JavaScript to native Rust:

• File Scanner: Parallel directory traversal for building the file tree
• Markdown Parser: Single-pass extraction of tags, wiki links, and markdown links
• Note Indexer: In-memory index with parallel build (powered by Rayon) and incremental updates via content hashing (xxHash)
• Backlink Updater: Parallel backlink resolution for note renames and moves
• Search: Keyword and tag-based note search against the native index
• Graph Data: Relationship graph (nodes and edges) built from the native index

ChangeLog

• Added file association support for .md/.markdown and .pdf/.docx/.doc
• Added application menu actions: Open..., Import..., Save, and Save All
• Improved single-instance and system "Open with" handling, including startup-argument file opening
• Added support for opening and editing Markdown files outside the notes directory
• Added external Markdown drag-and-drop options: "Edit original file" or "Import into Slog"
• Improved blank-page and editor drag-and-drop behavior (images/notes/external files)
• Improved image tab reuse logic and added "Copy image to clipboard"
• Improved PDF/Word import flow (installer checks, path-based import, and .doc warning copy)

Notes

• Registration, login, and AI features are optional. If you only use the note-taking features, no account is required.
• AI chat session history is saved as .md files in the Slog Notes/.chat sessions folder. Files in .chat sessions can be viewed in the editor but are read-only. To edit them, move the .md file out of the .chat sessions folder.

Slog is a local-first Markdown note-taking app focused on plain-text writing and long-term knowledge preservation. Your notes exist as files on your own device — no cloud lock-in, no proprietary formats. Lightweight, controllable, and durable.

Today, I shipped the very first version of Slog using a 10-year-old iMac. To release it today, I didn't have time to complete Apple Developer enrollment, so this build is distributed unsigned.

This is a small and honest beginning. If you're looking for a simpler, more future-proof way to write and keep your notes, you're welcome to try Slog.
