We have released Gravity Forms v1.0.1. If you have a license key activated, It should be available via automatic upgrade on your Plugins page in the WordPress dashboard. If you do not see that an upgrade is available, try refreshing the Plugins page in WordPress.
WordPress caches this data and only checks for plugin updates periodically. Refreshing the page should force it to check for available upgrades.
This releases patches a bug that may allow a user to unintentionally uninstall the plugin by submitting the Settings form using the enter key rather than clicking on the Submit button. It could only be reproduced in certain browsers.
We will be releasing Gravity Forms v1.1 next week, this release will add new features and functionality to the plugin.
