 # CHANGELOG
 
+## v0.4.33
+
+CHANGE: Updated react-bootstrap to version 2.10.2.
+
+CHANGE: Updated @mui/material to version 5.15.18.
+
+## v0.4.32
+
+FEATURE: New permission mode support for public frontends. Open permission mode frontends are available to all users in the service instance. Closed permission mode frontends reference the new `frontend_grants` table that can be used to control which accounts are allowed to create shares using that frontend. `zrok admin create frontend` now supports `--closed` flag to create closed permission mode frontends (https://github.com/openziti/zrok/issues/539)
+
+FEATURE: New config `defaultFrontend` that specifies the default frontend to be used for an environment. Provides the default `--frontend` for `zrok share public` and `zrok reserve public` (https://github.com/openziti/zrok/issues/663)
+
+FEATURE: Resource count limits now include `share_frontends` to limit the number of frontends that are allowed to make connections to a share (https://github.com/openziti/zrok/issues/650)
+
+CHANGE: The frontend selection flag used by `zrok share public` and `zrok reserve public` has been changed from `--frontends` to `--frontend`
+
+FIX: use controller config spec v4 in the Docker instance
+
 ## v0.4.31
 
 FEATURE: New "limits classes" limits implementation (https://github.com/openziti/zrok/issues/606). This new feature allows for extensive limits customization on a per-user basis, with fallback to the global defaults in the controller configuration.
