About changelog in Tag Manager

A changelog in Tag Manager is a place where you can find a chronologically ordered list of changes for your website. It makes it easy for you to see precisely what changes — tags, triggers, and variables — have been made between each publishing of the website.

A changelog consists of snapshots — a recording of the setup at a given time. A snapshot is made after you publish a website and is marked with a number, for example, Snapshot 5. Additionally, you can create a new snapshot manually before publishing the website. It will be marked with a number, for example, Snapshot 5.1.

But why do you need a snapshot? It’s not there only to be looked at. With a snapshot, you can revert your website to previous settings, publish previous settings, export settings from another website, and import settings to another website. In this article, we’ll explain how to do it.

  3. Click + Create new snapshot.
  4. The snapshot will be marked with a number, for example, Snapshot 3.1. The changes from this snapshot will be saved as a draft — they won’t be live.
