User-Visible OpenAFS Changes
+OpenAFS 1.9.1
+
+ All platforms
+
+ * Fix initial Rx Connection ID (CID) generation.

+ * Fix "vos zap -force" failures when the volume being zapped does not have
+ an entry in the fileserver's volume group cache (e.g., during fileserver
+ startup) (13896)
+
+ * Relax the length limits on some membership lists used in ptserver RPCs,
+ introduced in release 1.8.0 to prevent denial of service attacks, to
+ accommodate use cases of some larger existing sites (13844)
+
+ * Improved diagnostics and error messages (13898 13906..8 13938)
+
+ * Ensure that fileservers running in readonly mode actually reject all
+ write requests, but introduce a -admin-write switch allowing writes
+ by members of the system:administrators group (14018 14019)
+
+ All client platforms
+
+ * Require the -insecure_des switch to be passed to aklog and klog.krb5

+ fileserver after flushing large chunks of data to the server. This
+ issue was present on FreeBSD clients, but probably not Linux/Solaris
+ ones (13951) (RT #135041)
+
+ * After a VLDB lookup of a read-write volume already failed, don't bother
+ looking up corresponding read-only or backup volumes since those lookups
+ are bound to fail, in order to make the client more responsive and
+ avoid unnecessary load on the vlserver (13968)
+
+ * Allow a "vos rename" to succeed if the new volume name is the same as
+ that in the current VLDB, to make it possible to complete a previously
+ interrupted volume rename (14055)
+
+ * Allow processes which are sleeping due to PAG throttling to be killable
+ (13974).
+
+ * Fix set PAG failures due to signals (13975).
+
+ Linux clients
+
+ * Support mainline kernels up to and including 5.7 (14069 14094 14095
+ 14209 14210)

+ 5.3-rc2 and later (13910)
+
+ * Avoid possible deadlocks (13748 13765)

+ * Fix build of libuafs on ppc64le (14104)
+
+ * Fix build on certain recent 32-bit distributions (14234) (RT #135084)

+ (14031..7 14068)
+
+ Microsoft Windows
