 # Release Notes
 
+## Changes in Sawtooth Sabre 0.8.1
+
+* Remove smart permissions support. Smart permissions are currently not used
+  anywhere but did rely heavily on Pike.
+* Remove Pike. Pike has been moved to Grid and had a major update.
+* Add contract show/list subcommands to the `sabre` CLI.
+* Support custom keyfile in Sabre CLIs. Adds support for keyfile
+  (relative/absolute) path read from the CLI.
+* Break out checking if a signer is an admin into trait. The `AdminPermission`
+  trait will be used to decouple the Sabre Transaction Handler from Sawtooth
+  Settings when checking if a signer is an admin. Two implementation are
+  provided. One to still check Settings and one no-op implementation that always
+  returns true. When starting up the transaction processor provide the flag
+  `--admin-no-op` to treat all signers as admins.
