CNB Repositories provides code, branch, permission, and version management features,
helping developers break free from local environment constraints and focus on development.

## Core Features

### High-Availability Repositories

Cloud-based high-availability repositories ensure data security.
Built on Git version control, local and cloud code stays synchronized in real time.

### Online Code Browsing

Support both vertical and horizontal comparison modes.
Code before and after commits is clearly visible for comparison.

### Code Review

Pull Request supports line-by-line comparison and comments, with automatic reviewer
assignment on branch merges, making code review more efficient.

### Issue Tracking

Issues are used to record bugs, feature requests, or discussions,
supporting label categorization, priority marking, and comment interactions.

### Version Management

Automatically generate standardized version numbers on release,
linking directly with tasks/defects for traceable delivery.

### Branch Protection

Branch-level permission control ensures standardized team collaboration.
