+# v0.4.8
+
+FEATURE: The `sdk` package now includes a `sdk.Overview` function, which returns a complete description of the account attached to the enabled environment. Useful for inventorying the deployed shares and environments (https://github.com/openziti/zrok/issues/407)
+
+CHANGE: The `zrok access public` frontend configuration format has changed and now requires that the configuration document include a `v: 2` declaration. This frontend configuration format is now versioned and when the code updates the configuration structure, you will receive an error message at startup, provoking you to look into updating your configuration (https://github.com/openziti/zrok/issues/406)
+
+CHANGE: The title color of the header was changed from white to flourescent green, to better match the overall branding
+
+CHANGE: Tweaks to build and release process for logging and deprecations. Pin golang version at 1.21.3+ and node version at 18.x across all platforms
+
+CHANGE: Improvements to email invitation sent in response to `zrok invite` to correct broken links, some minor HTML issues and improve overall deliverability (https://github.com/openziti/zrok/issues/405)
+
+CHANGE: Added warning message after `zrok invite` submit directing the user to check their "spam" folder if they do not receive the invite message.
+
 # v0.4.7
 
 FEATURE: OAuth authentication with the ability to restrict authenticated users to specified domains for `zrok share public`. Supports both Google and GitHub authentication in this version. More authentication providers, and extensibility to come in future `zrok` releases. See the OAuth configuration guide at `docs/guides/self-hosting/oauth/configuring-oauth.md` for details (https://github.com/openziti/zrok/issues/45, https://github.com/openziti/zrok/issues/404)
