make changes

Changes have been made to the second season of the show.

A second change was made to the program at the same time.

Many changes have been made to the church over the years, both inside and outside.

The changes were not likely made before the fall of 1885.

Further changes were made in 1894 and from 1904 to 1907.

During the 1970s two changes were made to the system.

The report does not say why the change was made.

Few changes have been made to the church since then.

The game was almost gone by the time the changes were made.

I need to know what changes are being made, if any.
