Claude Code Changelog — Version Update Tracking

When to Use

• "claude changelog" / "what's new in CC" / "latest updates of claude code"
• "what's new in claude code" / "latest version"
• "what versions of claude code were released today"

Phase 1: Data Collection

1.1 Get Latest Releases

gh api repos/anthropics/claude-code/releases --jq '.[0:30] | .[] | {tag_name, published_at, body}' 2>/dev/null

gh

curl -s "https://api.github.com/repos/anthropics/claude-code/releases?per_page=30"

1.2 Determine Time Range

date

published_at

# Calculate UTC time for yesterday's CST 00:00 (i.e., yesterday's UTC 16:00)
SINCE=$(TZ=Asia/Shanghai date -v-1d +"%Y-%m-%dT00:00:00+08:00" 2>/dev/null || TZ=Asia/Shanghai date -d "yesterday" +"%Y-%m-%dT00:00:00+08:00")
echo "Filter start point: $SINCE"

Phase 2: Analysis and Classification

Edge Cases

• GitHub API unavailable: Fallback to pulling the raw CHANGELOG.md file directly with

  curl

  :

  curl -s "https://raw.githubusercontent.com/anthropics/claude-code/main/CHANGELOG.md" | head -200

• No network: Prompt the user to check network connection
• gh not installed: Automatically fallback to curl
• No versions in the time range: Output "No new versions released in this period" and attach information about the most recent version
