Claude Code Changelog — 版本更新追踪

Claude Code Changelog — Version Update Tracking

获取 Claude Code 昨天到当前的所有版本更新，输出结构化的 changelog 摘要报告。

Retrieve all version updates of Claude Code from yesterday to the current time, and output a structured changelog summary report.

When to Use

当用户请求以下操作时触发：

"claude changelog" / "CC 更新了什么" / "claude code 最新更新"
"what's new in claude code" / "最新版本"
"今天 claude code 发了什么版本"

Trigger this when the user requests the following operations:

"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: 数据采集

Phase 1: Data Collection

1.1 获取最新 releases

1.1 Get Latest Releases

运行以下命令获取最近的 GitHub Releases（拉取足够多以覆盖昨天到今天的所有版本）：

bash

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

如果

gh

命令不可用，fallback 到 curl：

bash

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

Run the following command to get the latest GitHub Releases (pull enough to cover all versions from yesterday to today):

bash

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

If the

gh

command is not available, fallback to curl:

bash

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

1.2 确定时间范围

1.2 Determine Time Range

默认范围：昨天 CST 00:00 到当前时间。

用户可覆盖默认范围：

用户输入	筛选规则
默认（无指定）	昨天 CST 00:00 ~ 当前时间
今天 / today	今天 CST 00:00 ~ 当前时间
最近N天	N天前 CST 00:00 ~ 当前时间
最新 / latest	仅最新 1 个版本
全部 / all	最近 30 个版本

先用

date

命令计算昨天 CST 00:00 对应的 UTC 时间戳，然后按

published_at

过滤 releases。

bash

undefined

Default Range: Yesterday CST 00:00 to current time.

Users can override the default range:

User Input	Filter Rule
Default (no specification)	Yesterday CST 00:00 ~ Current time
Today / today	Today CST 00:00 ~ Current time
Last N days	CST 00:00 N days ago ~ Current time
Latest / latest	Only the latest 1 version
All / all	Latest 30 versions

First use the

date

command to calculate the UTC timestamp corresponding to yesterday's CST 00:00, then filter releases by

published_at

bash

undefined

计算昨天 CST 00:00 的 UTC 时间（即昨天 UTC 16:00）

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 "筛选起点: $SINCE"


GitHub API 返回 UTC 时间，展示时转为 CST (UTC+8)。

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"


The GitHub API returns UTC time; convert it to CST (UTC+8) when displaying.

Phase 2: 分析与分类

Phase 2: Analysis and Classification

对筛选后的版本进行分析。

Analyze the filtered versions.

2.1 变更分类

2.1 Change Classification

将每个 release body 中的条目分为以下类别：

类别	标记	说明
NEW	新功能	新增的用户可感知功能
IMPROVE	改进	对已有功能的增强
FIX	修复	Bug 修复
SECURITY	安全	安全相关修复
PERF	性能	性能优化、内存优化
PLATFORM	平台	特定平台修复（Windows/macOS/Linux/VS Code）

Classify entries in each release body into the following categories:

Category	Tag	Description
NEW	New Features	New user-perceivable features
IMPROVE	Improvements	Enhancements to existing features
FIX	Bug Fixes	Bug fixes
SECURITY	Security	Security-related fixes
PERF	Performance	Performance optimizations, memory optimizations
PLATFORM	Platform	Platform-specific fixes (Windows/macOS/Linux/VS Code)

2.2 重要性标注

2.2 Importance Labeling

对每个变更评估重要性：

HIGH：新功能、breaking changes、安全修复
MEDIUM：功能改进、常见 bug 修复
LOW：平台特定修复、小优化

Assess the importance of each change:

HIGH: New features, breaking changes, security fixes
MEDIUM: Feature improvements, common bug fixes
LOW: Platform-specific fixes, minor optimizations

Phase 3: 输出报告

Phase 3: Output Report

输出 markdown 格式的 changelog 摘要：

markdown

**输出规则：**
- 时间统一用 CST (UTC+8) 展示
- 每个版本的变更条目保留原文，分类标签加在行首
- 版本按时间**从新到旧**排列
- 如果时间范围内无新版本，说明该时段无更新
- 将报告保存为 `claude-changelog-{date}.md` 到当前工作目录

Category	Count
New Features	{n}
Improvements	{n}
Bug Fixes	{n}
Performance	{n}
Platform	{n}


**Output Rules:**
- Display time in CST (UTC+8) uniformly
- Keep the original text of change entries for each version, with category tags added at the beginning of the line
- Sort versions **from newest to oldest** by time
- If there are no new versions within the time range, indicate that there are no updates in this period
- Save the report as `claude-changelog-{date}.md` in the current working directory

Edge Cases

GitHub API 不可用：fallback 到

curl

直接拉 CHANGELOG.md raw 文件：

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

无网络：提示用户检查网络连接
gh 未安装：自动 fallback 到 curl
时间范围内无版本：输出"该时段无新版本发布"并附最近一个版本的信息

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
