Here's both bulletin.

Service Action - Replace the Oxygen Sensor: https://drive.google.com/file/d/0B1e...ew?usp=sharing

Service Action - Retrofit Bracket for EGR Cooler: https://drive.google.com/file/d/1mDX...ew?usp=sharing

The one about the bracket has been around a year or so, while the O2 sensor is more recent.

People will not get a letter about this since it's not a recall but a service action. The opening paragraph describes this.

When I checked at the end of November 2014 there was no new service action about EGR bracket. The original service action was dated October 2013 and updated in November 2013 where marked "NEW" the bracket p/n is not marked "NEW" so I doubt there's more than one version.
