## [Unreleased]
## [0.1.2] - 2026-02-07
### Added
- **marathonctl CLI Tool**: New standalone command-line tool for controlling Marathon instances
- Beautiful TUI using ratatui with inline viewport mode
- Session status, peer list, and entity management commands
- `--show-sensitive` flag for debugging with full session IDs
- Easy-to-extend UI module with builder pattern API
### Security
- **Session ID Redaction**: Marathon CLI now redacts session IDs by default to prevent accidental exposure
- Shows only first 8 characters (e.g., `abc-def-...`)
- Explicit `--show-sensitive` flag required to view full IDs
- Fixes CodeQL cleartext-logging alerts (#1, #2, #3)
- **Dependency Updates**: Updated `lru` crate to v0.16.3 to address memory safety vulnerability
- Fixes Dependabot alert #1 (CVE: IterMut violates Stacked Borrows)
- Updated ratatui v0.29 → v0.30
- Updated pkarr v5.0.0 → v5.0.2
### Changed
- Extracted `marathonctl` from app crate into standalone publishable crate
- Updated all Marathon crate versions to 0.1.2 for consistency
- libmarathon: 0.1.2
- libmarathon-macros: 0.1.2
- marathonctl: 0.1.2
### Documentation
- Added `.envrc` setup instructions in CONTRIBUTING.md for GitHub token management
- Added crates.io publishing metadata to marathonctl
### Fixed
- Removed unnecessary ratatui/crossterm dependencies from app crate
- Added CodeQL suppression comment for database secret storage (false positive)
## [0.1.0] - 2026-02-06
### Added
#### Core Features
- CRDT-based synchronization using OR-Sets, RGA, and Last-Write-Wins semantics
- Peer-to-peer networking built on iroh with QUIC transport
- Gossip-based message broadcasting for multi-peer coordination
- Offline-first architecture with automatic reconciliation
- SQLite-backed persistence with WAL mode
- Cross-platform support for macOS desktop and iOS
#### Demo Application
- Replicated cube demo showcasing real-time collaboration
- Multiple instance support for local testing
- Apple Pencil input support on iPad
- Real-time cursor and selection synchronization
- Debug UI for inspecting internal state
#### Infrastructure
- Bevy 0.17 ECS integration
- Zero-copy serialization with rkyv

### Architecture
- **Networking Layer**: CRDT sync protocol, entity mapping, vector clocks, session management
- **Persistence Layer**: Three-tier system (in-memory → write buffer → SQLite)
- **Engine Core**: Event loop, networking manager, peer discovery, game actions
- **Platform Support**: iOS and desktop with platform-specific input handling
### Documentation
- RFC 0001: CRDT Synchronization Protocol
- RFC 0002: Persistence Strategy
- RFC 0003: Sync Abstraction
- RFC 0004: Session Lifecycle
- RFC 0005: Spatial Audio System
- RFC 0006: Agent Simulation Architecture
- iOS deployment guide
- Estimation methodology documentation
### Known Issues
- API is unstable and subject to change
- Limited documentation for public APIs
- Performance optimizations still needed for large-scale collaboration
- iOS builds require manual Xcode configuration
### Notes
This is an early development release (version 0.x.y). The API is unstable and breaking changes are expected. Not recommended for production use.
