 All notable changes to `nova-settings-tool` will be documented in this file.
 
+## 1.0 – 2019-09-29
+
+This is a major release. Upgrading will only take a few minutes and mostly just involves restructuring the config file, but this release is a major departure from previous versions of the package in a few ways, and therefore it **is not backwards compatible.**
+
+#### Breaking changes
+
+##### Completely restructure configuration file to reduce boilerplate and nesting
+
+The top-level `panels` array containing panels, which in turn contained settings, has been replaced with a single `settings` array. The structure of each setting has remained mostly the same, and the panel that a setting belongs to is now specified directly in that setting. Panels are computed based on the unique values of all settings' `panel` keys.
+
+Within individual settings:
+
+- the `name` key has been renamed to `label`
+- `description` has been renamed to `help` and now accepts any valid HTML
+- `link` has been removed because `help` accepts HTML
+- all keys are now optional except `key`
+
+The top-level `navigation` key in the config file has been renamed to `sidebar-label`.
+
+##### Rename config file from `settings.php` to `nova-settings-tool.php`
+
+The package's config file has been renamed to avoid possible conflicts. Fixes [#8](https://github.com/bakerkretzmar/nova-settings-tool/issues/8).
+
+##### Change package namespace from `SettingsTool` to `NovaSettingsTool`
+
+In your `NovaServiceProvider.php`, and anywhere else you're importing the tool, update your imports:
+
+```diff
+- use Bakerkretzmar\SettingsTool\SettingsTool;
++ use Bakerkretzmar\NovaSettingsTool\SettingsTool;
+```
+
+##### Remove support for assigning default values to settings
+
+This package doesn't affect the behaviour of your app, it just provide's a nice interface for managing settings in Nova—so setting something like `'default' => 'true'` on a toggle, as was previously possible, _wouldn't actually set a default value for the setting_, it would just change the way the setting was initially _displayed_, which could be misleading. Reverts [a4ad702](https://github.com/bakerkretzmar/nova-settings-tool/commit/a4ad702f29b9229e4d55f5150cb2deba47079932) and closes [#17](https://github.com/bakerkretzmar/nova-settings-tool/issues/17).
+
+#### Other changes and improvements
+
+- Add `number` and `select` setting types
+- Add support for settings file on a custom disk
+- Add ability to set a placeholder value on `text` and `textarea` settings
+- Simplify interface and consolidate save action
+- Adjust styles to more closely match Nova’s
+- Add bucketloads of tests
+
