# Claude Code v0.2.98 Changelog
Changes
7 itemsDynamic Model Configuration #
The CLI now provides enhanced model selection capabilities with runtime configuration support:
- Statsig Integration: Model configuration now integrates with Statsig for A/B testing and feature flags
- Environment Variable Priority: The
ANTHROPIC_MODELenvironment variable takes precedence over other configuration methods - Fallback Chain: Implements a robust fallback mechanism for model selection:
- Check environment configuration
- Check process environment variable
- Use Statsig-provided model
- Fall back to default model
# Set a specific model via environment variable
ANTHROPIC_MODEL=claude-3-opus-20240229 claude
# The model will persist across sessions if set in config
Settings UI Enhancements #
The settings panel now tracks configuration changes more comprehensively:
- Change Tracking: All setting modifications are now logged with telemetry events
- Model Configuration: Removed the separate model configuration UI in favor of environment-based settings
- Verbose Output: The verbose setting is now properly persisted and tracked
MCP Configuration File #
New support for .mcp.json configuration files in your project directory:
function saveMcpConfig(config) {
let mcpPath = path.join(cwd(), ".mcp.json");
writeFileSync(mcpPath, JSON.stringify(config, null, 2), { encoding: "utf8" });
}
This allows you to configure MCP servers and tools on a per-project basis.
Parent Process Detection #
New utilities for detecting if Claude Code is running as a child of a specific process:
function isChildOfProcess(pid) {
if (!isProcessAlive(pid)) return false;
// Walks up the process tree to check ancestry
// Useful for IDE integration detection
}
IDE Name Resolution #
Enhanced IDE detection with friendly name mapping:
function getIDEDisplayName(ideId) {
switch (ideId) {
case "vscode": return "VS Code";
case "cursor": return "Cursor";
case "windsurf": return "Windsurf";
case "pycharm": return "PyCharm";
case "intellij": return "IntelliJ IDEA";
case "webstorm": return "WebStorm";
// ... and many more IDEs
}
}
Supports detection of 20+ different IDEs including JetBrains suite, VS Code variants, and Android Studio.
Enhanced Limit Status Tracking #
The rate limit status now includes time-based information:
// Previous version
{ status: "limited" }
// New version
{
status: "limited",
hoursTillReset: 3 // Hours until rate limit resets
}
This provides users with better visibility into when they can resume using the service.
Conversation Path Resolution #
New functionality to resolve and track conversation paths across sessions:
async function resolveConversationPaths() {
// Automatically resolves parent-child relationships
// between conversations for better context tracking
}
This helps maintain conversation context when switching between related discussions.
