规范版本演进
治理本页清单由 scripts/gen-omid-spec.mjs 自 IAB Tech Lab 官方源生成，描述为官方英文原文；采集基线见页尾。
定位与职责
开放测量接口定义（Open Measurement Interface Definition，OMID）规范自 1.0 起的版本序列与每版的能力增量：1.2 支持浏览器集成，1.3 改进广告会话分类并增加音频支持，1.4 新增 CTV 事件，1.5 增加 Web 视频与 CTV（Samsung、LG）支持，1.6 增加设备认证。规范版本（spec version）与库版本（libraryVersion）不是同一序列：三端各自发布库版本，且 JS 库版本的修订号多于规范版本。

规范版本与能力增量
| 版本 | 所属端 |
|---|---|
| OMID 1.0 | Android · iOS · JS |
| OMID 1.2 | Android · iOS · JS |
| OMID 1.3 | Android · iOS · JS |
| OMID 1.4 | Android · iOS · JS |
| OMID 1.5 | Android · iOS · JS |

规范版本序列取自 IAB Tech Lab 标准页（2026-09-22 采集）；各版本的能力增量以 OM SDK JS 仓库 CHANGELOG.md 的官方原文为准，见下方重大更新列表。
规范版本（OMID 1.0 / 1.2 / 1.3 / 1.4 / 1.5 / 1.6）与库版本（libraryVersion）是两套序列：三端各自发布库版本，JS 库的修订号多于规范版本，同号不保证同日。
标准页列出的规范版本为 1.0 / 1.2 / 1.3 / 1.4 / 1.5 / 1.6，没有 1.1；而 OM SDK JS 的 CHANGELOG.md 含 1.1.0（2018-03-29，首个正式可用版本）至 1.1.4 共五个库版本。规范版本与库版本是两套序列，本站按各自出处分别登记，不推断对应关系。
