You may be aware that OWASP 2017 was recently updated to OWASP 2021.

The biggest changes involved updates to the original OWASP Top 10.

• There are now three new categories; four categories with naming and scoping changes; and some consolidation in the Top 10 for 2021.

The below link leads to a diagram on the official OWASP website that explains these changes in more detail.
