 - Linking `iDynTree::idyntree-sensors` is deprecated, you can just link `iDynTree::idyntree-model` instead, or just search and replace `iDynTree::idyntree-sensors` with an empty string if you are already linking `iDynTree::idyntree-model` (https://github.com/robotology/idyntree/pull/1104).
 - Including `<iDynTree/Core/@headername@.h>`, `<iDynTree/Model/@headername@.h>`, `<iDynTree/Sensors/@headername@.h>`, `<iDynTree/ModelIO/@headername@.h>`, `<iDynTree/Estimation/@headername@.h>`, `<iDynTree/yarp/@headername@.h>` is deprecated, just include `<iDynTree/@headername@.h>` . To perform this migration, just search and replace `<iDynTree/Core/` with `<iDynTree/`, `<iDynTree/Model/` with `<iDynTree/`, `<iDynTree/Sensors/` with `<iDynTree/`, `<iDynTree/ModelIO/` with `<iDynTree/`, `<iDynTree/Estimation/` with `<iDynTree/`, `<iDynTree/yarp/` with `<iDynTree/` (https://github.com/robotology/idyntree/pull/1104).
 - Several methods that take in input both a `iDynTree::Model` and a `iDynTree::SensorsList` have been deprecated, users are suggested to call the variant that takes in input only the `iDynTree::Model`, if necessary by populating correctly the sensors of the `iDynTree::Model` via the `iDynTree::Model::sensors` method (https://github.com/robotology/idyntree/pull/1106).
+- Several classes that ended in `Raw` are deprecated, and in their place their non-Raw counterpart should be used. In particular, the pair "deprecated"/"replacement"  is : `iDynTree::PositionRaw`/`iDynTree::Position`, `iDynTree::RotationRaw`/`iDynTree::Rotation`, `iDynTree::RotationalInertiaRaw`/`iDynTree::RotationalInertia` and   `iDynTree::SpatialInertiaRaw`/`iDynTree::SpatialInertia` (https://github.com/robotology/idyntree/pull/1114).
