 # Upgrade Guide
 
+## Upgrading From Socialstream 2.x To Socialstream 3.x
+
+### Changes
+
+#### Disabling Socialstream
+
+To disable Socialstream in v3, you will need to update your existing `SocialstreamServiceProvider.php` to include the following code snippet in your providers `boot` method:
+
+```php
+    Socialstream::enabled(fn () => false);
+```
+
+The function accepts a callback so if you wanted to implement more complex logic, you may do so.
+
+> Note, the callback MUST return a boolean
+
+#### Providers
+
+V3 introduces a new `Providers` class, for defining what Socialite providers you have enabled in your config. This class is also used in the socialstream.blade.php stub and the connected-account.blade.php component stub. Please update any Socialite providers you have in your `socialstream.php` config file to use this class, e.g:
+
+
+```php
+use \JoelButcher\Socialstream\Providers;
+
+return [
+    // ...
+
+    'providers' => [
+        Providers::google(),
+        Providers::facebook(),
+    ],
+
+];
+```
+
+#### Remember Sessions
+
+V3 of Socialstream move the remember session config variable into the 'features' config array. During your upgrade, if you have previously set this config variable to `true`, you will need to add it to your features list.
+
+```php
+return [
+    // ...
+
+    'features' => [
+        Features::rememberSession(),
+    ],
+
+];
+```
+
+#### Token Column Lengths
+
+In version 3.x, we've fixed an issue with the length of tokens and refresh tokens being too long for the columns in the database.
+
+To fix this yourself, you should create a new `connected_accounts` migration:
+
+```sh
+php artisan make:migration update_connected_accounts_token_lengths --table=connected_accounts
+```
+
+Once done, you should then add the following code to the `up` method:
+
+```php
+    $table->string('token', 1000)->change();
+    $table->string('refresh_token', 1000)->change();
+```
+
+#### Provider Avatars
+
+In v3, we've updated the provider avatars feature to download the avatar from the url provided by the Socialite user. If you have opted to use the `providerAvatars` feature in your config's features definition, you should add the `SetsProfilePhotoFromUrl` trait to your user model:
+
+```php
+<?php
+
+use JoelButcher\Socialstream\SetsProfilePhotoFromUrl;
+
+class User extends Authenticatable
+{
+    // ...
+    use SetsProfilePhotoFromUrl;
+
+    // ...
+}
+```
+
+It's worth noting that if you still to load the users profile photo from a URL, you will need to keep the `getProfilePhotoUrlAttribute` method override published by Socialstream, in your user model.
+
+#### Connected Account Policy
+
+V3 uses a new policy to determine whether or not a user can access certain functionality. To ensure compatibility with v3, make sure you copy the stub found [here](https://github.com/joelbutcher/socialstream/blob/3.x/stubs/app/Policies/ConnectedAccountPolicy.php) to your `app/Policies` directory.
+
+#### Updating Connected Accounts
+
+Socialstream v3 will now keep your connected accounts up to date whenever a user uses SSO with your application. updating a users OAuth token and refresh token on every successful login. To make sure this works for you, copy [this stub](https://github.com/joelbutcher/socialstream/blob/3.x/stubs/app/Actions/Socialstream/UpdateConnectedAccount.php) into the `app/Actions/Socialstream` directory. You will then need to add the following to your `app\Providers\SocialstreamServiceProvider.php`:
+
+```php
+use App\Actions\Socialstream\UpdateConnectedAccount;
+use JoelButcher\Socialstream\Socialstream;
+
+// Add this to the 'boot' method.
+Socialstream::updateConnectedAccountsUsing(UpdateConnectedAccount::class);
+```
+
+#### Resolving Users from Socialite
+
+To allow additional flexibility, v3 allows you to override how your app resolves users from Socialite. For example, you may wish to call the `stateless` method, like so:
+
+```php
+$user = Socialite::driver('facebook')->stateless()->user();
+```
+
+To ensure v3 compatibility, copy the `ResolveSocialiteUser` action stub found [here](https://github.com/joelbutcher/socialstream/blob/3.x/stubs/app/Actions/Socialstream/ResolveSocialiteUser.php) to your `app/Actions/Socialstream` directory and add the following to your `app\Providers\SocialstreamServiceProvider.php`:
+
+```php
+use App\Actions\Socialstream\ResolveSocialiteUser;
+use JoelButcher\Socialstream\Socialstream;
+
+// Add this to the 'boot' method.
+Socialstream::resolvesSocialiteUsersUsing(ResolveSocialiteUser::class);
+```
+
