We present new measurements of the temperature anisotropy in the cosmic microwave background using Arcminute Cosmology Bolometer Array Receiver (ACBAR). Significant improvements in sensitivity over previous data release were achieved by a combination of more efficient analysis techniques and the inclusion of more data. Together with the CBI measurements at lower photon frequencies, and the WMAP results on large angular scales, the joint ACBAR/CBI/WMAP power spectrum represents the current best knowledge of the temperature anisotropy between l=2 and 3000. Cosmological implications, current status of the instrument, and prospects for further improvements will be discussed.
