# 开发者真正关心的更新日志与产品动态
## 适用场景

当你需要撰写开发者真正愿意阅读并关心的发布说明与产品更新时使用本技能。本技能涵盖更新日志格式、版本号沟通、重大变更公告、弃用通知，以及为新功能造势。触发词：更新日志、changelog、发布说明、release notes、产品更新、product updates、版本号、versioning、重大变更、breaking change、弃用、deprecation、发布动态、发布节奏、release cadence。


发布说明是面向开发者的沟通，而非文档。写得好时，它们能建立信任、展示产品节奏，并将每次更新转化为营销契机。

## 概述

更新日志服务于多种受众并承担不同目的：
- **活跃开发者**："有哪些变更会影响我的集成？"
- **评估期的开发者**："这个产品还在积极维护吗？"
- **开发者布道者**："哪些内容值得分享给我的受众？"
- **你的团队**：历史上线内容与上线时间的记录

本技能帮助你撰写能够传递信息、建立信任，并偶尔让人眼前一亮的更新日志。

## 开始之前

请先查阅 **developer-audience-context** 技能以了解：
- 你的开发者更倾向通过什么渠道接收更新？
- 他们最关心哪些类型的变更？
- 他们需要多详细的说明？
- 他们对破坏性变更的容忍度如何？

你的更新日志语气与详略程度应与受众匹配。

### 好条目 vs 坏条目

**优秀的更新日志条目：**

  request, reducing API calls by 90% for bulk operations.
  [See docs](https://github.com/jonathimer/devmarketing-skills/tree/main/skills/changelog-updates/link) (#198)

### Fixed
- Fixed timeout errors when processing files larger than 10MB.
  Uploads now stream in chunks, eliminating memory issues. (#234)

### Deprecated
- `legacy_auth()` will be removed in v3.0.0 (scheduled for March 2024).
  Migrate to `oauth_auth()` using our [migration guide](https://github.com/jonathimer/devmarketing-skills/tree/main/skills/changelog-updates/link).
```

**糟糕的更新日志条目：**
```markdown

## 版本号沟通

### 向用户解释语义化版本

帮助开发者理解版本号的含义：

```markdown
# Versioning

We follow [Semantic Versioning](https://semver.org/):

- **Major versions (3.0.0)**: May include breaking changes.
  Check the migration guide before upgrading.

- **Minor versions (2.3.0)**: New features, backward compatible.
  Safe to upgrade.

- **Patch versions (2.3.1)**: Bug fixes only.
  Always safe to upgrade.
```

### 版本固定建议

帮助开发者做出合理选择：

```markdown
# Recommended Version Constraints

For stability, we recommend:
- `"myapi": "^2.3.0"` - Get patches and minor updates
- `"myapi": "~2.3.0"` - Get patches only

For production systems:
- Pin exact versions: `"myapi": "2.3.0"`
- Review changelogs before upgrading
- Test in staging first
```

### API 版本号沟通

```markdown
# API Versions

## Current Versions
- **v2** (current): Full support, recommended for new integrations
- **v1** (legacy): Security fixes only, sunset March 2025

## Version Lifecycle

| Current | Ongoing | Full support, new features |
| Legacy | 12 months | Security fixes only |
| Deprecated | 6 months | No updates, migration required |
| Sunset | - | No longer available |

## Specifying Version
