+    The ``BackendV1`` model has been removed following its deprecation in 
+    Qiskit 1.2.0. This includes the ``BackendV1`` class as well as related
+    modules and utils, as they have been superseded by the :class:`.BackendV2` 
+    model. The list of removed items includes:
+
+    * ``BackendV1`` class: the core of the removed model
+
+    * all elements in `qiskit/providers/models`, as they were used to represent 
+      components of the ``BackendV1`` model:
+
+        * ``BackendConfiguration``
+        * ``BackendProperties``
+        * ``BackendStatus``
+        * ``QasmBackendConfiguration``
+        * ``PulseBackendConfiguration``
+        * ``UchannelLO``
+        * ``GateConfig`` 
+        * ``PulseDefaults`` 
+        * ``PulseQobjDef``
+        * ``Command``
+        * ``GateProperties``  
+        * ``Nduv``    
+        * ``JobStatus``: This class has been superseded by the more widely used :class:`.JobStatus`
+        * ``PulseDefaults``
+
+    * ``BackendV2Converter`` class: used to convert from ``BackendV1`` to :class:`.BackendV2` 
+
+    * ``convert_to_target`` function: used to build a :class:`.Target` instance from 
+      legacy ``BackendV1`` components (such as ``BackendConfiguration`` or ``BackendProperties``)
+
+    * ``BackendPropertyError`` and ``BackendConfigurationError``: exceptions linked to removed classes
+
+upgrade_misc:

+    The ``Qobj`` structure and related classes, deprecated in Qiskit 1.2.0,
+    have been removed. They were introduced as part of the ``BackendV1``
+    workflow and are no longer necessary for interacting with :class:`.BackendV2` backends.
+    This removal includes:
+
+    *    ``QobjExperimentHeader``
+    *    ``QobjHeader``
+    *    ``QasmQobj``
+    *    ``QasmQobjInstruction``
+    *    ``QasmQobjExperimentConfig``
+    *    ``QasmQobjExperiment``
+    *    ``QasmQobjConfig``
+    *    ``QasmExperimentCalibrations``
+    *    ``GateCalibration``
+    *    ``PulseQobj``
+    *    ``PulseQobjInstruction``
+    *    ``PulseQobjExperimentConfig``
+    *    ``PulseQobjExperiment``
+    *    ``PulseQobjConfig``
+    *    ``QobjMeasurementOption``
+    *    ``PulseLibraryItem``
+
+    The :class:`.MeasLevel` and :class`.MeasReturnType` classes, previously defined in 
+    ``qobj/utils.py``, have been migrated to ``result/models.py`` following the removal
+    of the ``qobj`` module. These classes were not part of the public API, so there should
+    not be any effect on users from this move.
