 # node-triton changelog
 
-## 3.0.1 (not yet released)
+## 3.1.0 (not yet released)
+
+- New (hidden for now, i.e. experimental) `triton env ...` to dump
+  `eval`able shell commands for
+  [node-smartdc](https://github.com/joyent/node-smartdc) environment setup for
+  a given Triton CLI profile. E.g.:
+
+        eval $(triton env east1)
+        sdc-listmachines
+
+  I think this should grow to support setting up Docker env as well.
 
 - #54 `triton rbac role-tags` for now can't be hidden (as long we have the
   need to role-tag raw resource URLs like '/my/images').
+
 - #54 `triton rbac apply --dev-create-keys-and-profiles` for
   experimenting/dev/testing to quickly generate and add user keys and setup
   Triton CLI profiles for all users in the RBAC config.
+
 - #54 RBAC support, see <https://docs.joyent.com/public-cloud/rbac> to start.
     - `triton rbac info` improvements: better help, use brackets to show
       non-default roles.

     - change `triton rbac user USER` output a little for the 'keys' (show
       the key fingerprint and name instead of the key content), 'roles',
       and 'default_roles' fields.
+
 - #54 *Drop* support for shortIds for `triton rbac {users,roles,policies}`
   commands. They all have unique *`name`* fields, just use that.
+
 - #54 `triton rbac apply` will implicitly look for a user key file at
   "./rbac-user-keys/$login.pub" if no `keys` field is provided in the
   "rbac.json" config file.
+
 - Change default `triton keys` and `triton rbac keys` output to be tabular.
   Otherwise it is a little obtuse to see fingerprints (which is what currently
   must be included in a profile). `triton [rbac] keys -A` can be used to
