This contribution will present the latest developments after the MALTA and Mini-MALTA sensors. It will illustrate the improvements and results of the Czochralski substrate with a bigger depletion zone to improve efficiency. It will also present the plans for MALTA2, which will be produced in late 2020, with enlarged transistors to reduce noise and cascoded front-end corrected slow control to improve chip operation.
