Muninn for VS Code v1.0.0 Preview

Added

• A reading-first rich Markdown editor with formatting controls, editable tables, GFM tasks and strikethrough.
• Native New Markdown Note, image, file-link and heading commands, with a raw Markdown escape hatch.
• A contextual Muninn: Report issue status-bar action and native VS Code issue reporter, plus GitHub forms for preview feedback.
• Workspace-trust-gated Mermaid diagrams, accessible editor controls and configurable reading width.
• Operation acknowledgments, independent-edit merging and unsaved recovery copies for conflicting or unapplied drafts.
• Installed-VSIX tests on Windows, macOS and Linux, production package budgets and generated third-party notices.
• GitHub Actions publishing to the VS Code Marketplace and Open VSX, with nonpublishing package and credential verification.

Fixed

• Save/source/close synchronization, focused table input persistence and duplicate undo processing.
• Source churn in no-op round trips and rich edits, escaped/aligned table cells and intermediate whitespace typing.
• Restricted-workspace Mermaid enforcement, resource scopes, remote image fetches and image-size checks.
• Automatic editor preference mutation, duplicated diagram presentation, toolbar action state and cancellation.

Release

• Version 1.0.0 retains the Marketplace Preview badge and is distributed on the pre-release channel.
• Requires VS Code 1.85.2 or later. Contributor and CI tooling use Node 24.
• AGPL-3.0-only, with no telemetry.

Preview limitations

• Rich edits that cannot preserve the original Markdown safely require the Source editor.
• Manual screen-reader, real Remote SSH/Codespaces, and long-document performance acceptance remain outstanding; see testing.
