EMIR was shipped to the GTC on May 2016 and had its first light on June 2016. After a short and intense commissioning period, a Scientific Verification phase took place in the first half of 2017 and the instrument began its routinely operation at the GTC by the end of that year. Since the beginning, the EMIR performances have been severely hampered by the many instabilities in the infrared detector, a 2048×2048 Hawaii2, built with the old original technology of the Teledyne Hawaii series. Despite of this, the instrument has proven to be powerful enough so as to produce a significant number of important scientific contributions. Starting in 2020, we initiated a new project aimed at equip EMIR with a most modern detector array, free from the artefacts that contaminated the observations with the old one. As a results, and after almost 6 years of routine operations at the GTC, EMIR has recently been upgraded with a new Hawaii2RG infrared detector which has replaced the old Hawaii2 that equipped the instrument in origin. The new detector is not only more sensitive in virtually every aspect compared to the old one, but it also eliminates many of the instabilities of the original detector that severely hindered EMIR's performance., while it is not free from artefacts that affect the noise in the measurements. This is particularly noticeable under high illumination conditions, i.e. broad brand imaging, as it will be shown below. In addition, the new detector sits on a remotely operated gimbal mount that permits an exquisite alignment in the field of view. In this contribution, we will describe the capabilities of the new EMIR and will show some fresh scientific results, and will also flag some features that users should be aware of.
