Duplicate Check is expected to have six minor releases in 2025: three releases focusing on new features, and three maintenance updates containing mainly improvements and bugfixes.
Next to minor releases, Duplicate Check can do patch releases for bug fixes that need immediate attention, without any prior notification.
For release notes of the latest and previous releases, see the release notes page.

Duplicate Check is released in two phases - first a sandbox release, then a production release one or two weeks later.

Both minor and patch releases are pushed automatically. There is no action required to receive these releases. If you disabled auto-updates, you can download the latest version from the AppExchange website soon after the production release date; usually it is published there a few days later.

Please note that the dates listed below might be subject to change.
