+This is due to not re-including debugging information in Makevars, as specified by the CRAN policy and pointed out by Prof Brian Ripley. A shared-object (.so) is larger than perhaps necessary, but compliant with CRAN policies.
+
+## Changes in agtboost 0.9.3
+Following e-mail from Prof Brian Ripley:
+"The CRAN policy contains
+- Packages should not attempt to disable compiler diagnostics, nor to
+remove other diagnostic information such as symbols in shared objects."
+Thus, agtboost 0.9.3 re-includes debugging information. This leads to package being larger on some OS.

 ## Changes in agtboost 0.9.2
 Some patching of serialization/deserialization of model objects, along with new features for model training. A deprecation notice is included, and package should be smaller on some OS due to stripping debugging information.
