+	* v0.12
+	* new: command option `3Dpsob' and 3d views file entry `PSOB' added on
+	request	of J. Bowman (Asymptote)
+	* fix: empty option list of \includemedia led to crash, improved Asymptote
+	compatibility
+
 2012-08-14
 	* v0.11
 	* new: package option `bigfiles' added which defers file embedding to the
 	ps->pdf step; needed when latex aborts with error `TeX capacity exceeded'
