"Η αποφοίτηση φέτος ήταν ιδιαίτερη."

Translation: The graduation this year was special.

[Speugenia]

Under @Another correct solution" it reads: "This year the was distinctive", obviously the word "graduation" is missing.

Also, "distinctive" translates to "διακριτικός (-ή, ό)" or "ξεχωριστός (-ή, ό)", not so much "ιδιαίτερος (-η, -ο)" -which better translates to "particular, special or specific", depending on the context of course.

"The graduation has been special this year" is not correct?

Γίνεται κατάχρηση της λέξης "ιδιαίτερος" σ'αυτό το δέντρο.

Why is a cheese called "φέτα τυρί"? Do it mean "this years cheese"?

Why is a cheese called "φέτα τυρί"? Do it mean "this years cheese"?

φέτα by itself means "slice". It has nothing to do with φέτος "this year".
