In this survey we provide an overview of some recent developments in the construction of moduli spaces using stack-theoretic techniques. We will also explain the analogue of Harder-Narasimhan stratifications for general stacks, known as <inline-formula content-type="math/mathml"> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" alttext="normal upper Theta"> <mml:semantics> <mml:mi mathvariant="normal">Θ</mml:mi> <mml:annotation encoding="application/x-tex">\Theta</mml:annotation> </mml:semantics> </mml:math> </inline-formula>-stratifications.
