This module adds a tab for sufficiently permissioned users. The tab shows all revisions like standard Drupal but it also allows pretty viewing of all added/changed/deleted words between revisions.

Versions

There are currently 2 supported versions of Diff.

The 8.x-1.x branch is a legacy branch that is effectively unmaintained and obsolete.

Migrating 8.x-1.x to 2.0.0.

This should be a smooth upgrade. 8.x-1.10 will be marked as unsupported sometime between August and October 2026

Simply run

composer require drupal/diff:^2.1.0

You are strongly advised to update to 2.1.0, there should be no compatibility issues between 8.x-1.10 and 2.0.0.

2.x
This is a new branch started by acbramley in an attempt to bring the Diff module up to modern coding standards.

2.0.0 - functionally equivalent to 8.x-1.10 but refactored and modernised

2.1.0 - Diff now supports all entity types

It requires:
- Drupal 10.5 (this will be raised as Drupal 10's minors go EOL)
- PHP 8.1 (this will be raised as PHP's minors go EOL)

8.x-1.x
This branch supports Drupal 10 and Drupal 11. 8.x-1.10 is the final release on this branch.

You should be able to upgrade to 2.1.0 with no issues.
