+- update to 2.51:
+  * Fix capsh installation
+  * Add an autoauth module flag to pam_cap.so
+  * Unified libcap/cap (Go) and libcap (C) default generation of external format binary data
+  * API enhancement cap_fill() and (*cap.Set).Fill() - to permit copying one
+    capability flag to another.
+  * --explain=cap_foo: describe what cap_foo does
+  * --suggest=phrase: search all the cap descriptions and describe those that match the phrase
+  * Add "keepcaps" module argument support to pam_cap.so (reported by Zoltan Fridrich. Bug 212945)
+  * extend libcap to include cap_prctl() and cap_prctlw() functions to regain
+    feature parity with Go "cap" package. These are only needed when linking
+    against -lpsx for keepcaps POSIX semantics.
+  * this likely requires substantial application changes to make Ambient
+    capability support usable in general, but doing our part for the admin.
+  * Add a test case for recent kernel fix
+  * Go pragma fix for convenience functions in "cap" module
+
