Issues with porting from v1.8.2 to 1.9.0-beta

Hi,

There are quite few differences between v1.8.2 and v1.9.0-beta1. Is there any porting guidelines if one needs to move to the new version?

There are quite many changes which are really confusing as to whether they were removed on purpose are are reflected somewhere else in a different form.

The following file, has quite many changes between these versions and it would be great if some one can explain why the difference.

PX4-Autopilot/drv_accel.h at v1.8.2 · PX4/PX4-Autopilot · GitHub and PX4-Autopilot/drv_accel.h at v1.9.0-beta1 · PX4/PX4-Autopilot · GitHub . v1.9.0-beta1 has removed quite many stuff from this file.

regards
Arun
