Atacama Cosmology Telescope (ACT) was until recently one of two high-resolution Cosmic Microwave Background (CMB) telescopes, with a 6 m primary mirror and a resolution 5x that of the Planck space telescope. The previous cosmology data release, DR4, covered 4 years of data with polarization-sensitive detectors, covering the period 2013-2016. After that, the telescope was upgraded to the AdvancedACT configuration followed by another 6 years of observation (2017-2022). We are finally getting ready to release this data as data release 6 (DR6), which represents a factor 6-10 increase in sensitivity compared to DR4. It covers roughly half the sky and is several times deeper than Planck there. I will present ACT, the DR6 data set and maps, the current science results as well as previews of the soon upcoming ones, and, finally, a look towards ACT's successor: Simons Observatory.
