Version History

The overall ATT&CK catalog is versioned using a major.minor version schema. The bi-annual content releases listed on the updates pages increment the major version number. The minor version number increments for our other small releases, which include typo and data corrections but not typically new content.

Below are a list of versions of the ATT&CK website preserved for posterity, including a permalink to the current version of the site:
