* The merge process preserves the modification timestamp of files that it
installs. The unmerge process will not uninstall files that are claimed by
another package in the same slot.
+* PDEPEND is now installed as soon as possible so that it behaves more like
+ RDEPEND. This makes PDEPEND more useful for breaking the dependency cycles
+ that are sometimes triggered by RDEPEND and DEPEND.
