NetBSD still uses a 4-clause license equivalent to the original BSD license.
A 2-clause BSD-like license also exists which deletes the third clause, prohibiting use of the copyright holder's name for endorsement purposes. Removal of that clause makes the license functionally equivalent to the MIT License. This is the only BSD-style license permitted for certain libraries included in KDE.
FreeBSD also uses a 2-clause license with an additional statement at the end that the views of contributors are not the official views of the FreeBSD Project.
OpenBSD uses a license modeled after the ISC license for all additional software created by the project, as it is functionally a two-clause BSD-styled license, with no additional clauses or consequences involved.
