The Cryogenic Underground Observatory for Rare Events (CUORE) is the first cryogenic experiment searching for
0
ν
β
β
decay that has been able to reach the one-tonne mass scale. The detector, located at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy, consists of an array of 988
TeO
2
crystals arranged in a compact cylindrical structure of 19 towers. CUORE began its first physics data run in 2017 at a base temperature of about 10 mK and in April 2021 released its
3
rd
result of the search for
0
ν
β
β
, corresponding to a tonne-year of
TeO
2
exposure. This is the largest amount of data ever acquired with a solid state detector and the most sensitive measurement of
0
ν
β
β
decay in
130
Te
ever conducted . We present the current status of CUORE search for
0
ν
β
β
with the updated statistics of one tonne-yr. We finally give an update of the CUORE background model and the measurement of the
130
Te
2
ν
β
β
decay half-life and decay to excited states of
130

, studies performed using an exposure of 300.7 kg yr.
