 ## [Unreleased]
 
+## [2.3.0] - 2025-07-29
+
+In this release, we have migrated to using Qiskit's `Target` class to represent quantum devices.
+This change allows for better compatibility with the latest MQT Bench version and improves the overall usability of the library.
+Beyond that, we also support Qiskit v2 now.
+
+Furthermore, both the ML and RL parts of MQT Predictor have been refactored to enhance their functionality and usability:
+The ML setup has been simplified and streamlined, making it easier to use and integrate into your workflows.
+The RL action handling has been updated to utilize dataclasses, which improves the structure and clarity of the code, making it easier to understand and maintain.
+
+### General
+
+MQT Bench has moved to the [munich-quantum-toolkit](https://github.com/munich-quantum-toolkit) GitHub organization under https://github.com/munich-quantum-toolkit/predictor.
+While most links should be automatically redirected, please update any links in your code to point to the new location.
+All links in the documentation have been updated accordingly.
