## What This PR fixes some broken links that have been hanging around in the docs for what seems like a very long time. ## Why As discovered by the link check in #1912, there are a fair few broken links in the docs. Everyone hates broken links because it makes it harder to understand what they were supposed to be pointing at. ## How There are 3 types of links that have been fixed: - Links that should have been internal but were absolute. E.g. `https://docs.getunleash.io/path/article` that should have been `./article.md` - External links that have changed, such as Slack's API description - GitHub links to files that either no longer exist or that have been moved. These links generally pointed to `master`/`main`, meaning they are subject to change. They have been replaced with permalinks pointing to specific commits. ----- * docs: fix slack api doc link * docs: update links in migration guide * docs: fix broken link to ancient feature schema validation * docs: update links to v3 auth hooks * docs: update broken link in the go sdk article * Fix: use permalink for GitHub link * docs: fix wrong google auth link

Generally, the intention is that unleash-server should always provide support for clients one major version lower than the current one. This should make it possible to upgrade unleash gradually.
Upgrading from v3.x to v4.x
Before you upgrade we strongly recommend that you take a full database backup, to make sure you can downgrade to version 3.
You can also read the highlights of what's new in v4.
1. All API calls now requires token.
If you are upgrading from Unleash Open-Source v3 client SDKs did not need to use an API token in order to connect to Unleash-server. Starting from v4 we have back-ported the API token handling for Enterprise in to the Open-Source version. This means that all client SDKs now need to use a client token in order to connect to Unleash.
Read more in the API token documentation.
2. Configuring Unleash
We have done a lot of changes to the options you can pass in to Unleash. If you are manually configuring Unleash you should have a look on the updated configuring Unleash documentation
3. Role-based Access Control (RBAC)
We have implemented RBAC in Unleash v4. This has totally changed the permission system in Unleash.
Required actions: If you have implemented "custom authentication" for your users you will need to make changes to your integration:
- extendedPermissions option has been removed. You can no longer specify custom permission per-user basis. All "logged_in users" must belong to a "root" role. This can be "Admin", "Editor" or "Viewer". This is taken care of when you create new users via userService.
- All "logged-in users" needs to be defined in Unleash and have a unique ID. This can be achieved by calling "createUser" on "userService".
Code example:
const user = userService.loginUserWithoutPassword(
'some@getunleash.io',
false, // autoCreateUser. Set to true if you want to create users on the fly.
);
// The user needs to be set on the current active session
req.session.user = user;
4. Legacy v2 routes removed
Only relevant if you use the enableLegacyRoutes option.
In v2 you could query feature toggles on /api/features. This was deprecated in v4 and we introduced two different endpoints (/api/admin/features and /api/client/features) to be able to optimize performance and security. In v3 you could still enable the legacy routes via the enableLegacyRoutes option. This was removed in v4.
5. Unleash CLI has been removed
Unleash no longer ships with a binary that allows you to start Unleash directly from the command line. From v4 you need to either use Unleash via docker or programmatically.
Read more in our getting started documentation
Upgrading from v2.x to v3.x
The notable change introduced in Unleash v3.x is a strict separation of API paths for client requests and admin requests. This makes it easier to implement different authentication mechanisms for the admin UI and all unleash-clients. You can read more about securing unleash.
The recommended approach is to first upgrade the unleash-server to v3 (which still supports v2 clients). After this is done, you should upgrade all your clients to v3.
After upgrading all your clients, you should consider turning off legacy routes, used by v2 clients. To do this, set the configuration option enableLegacyRoutes to false as described in the page on configuring Unleash v3.
Upgrading from v1.0 to v2.0
Caveat 1: Not used db-migrate to migrate the Unleash database?
In FINN we used liquibase, for internal reasons, to migrate our database. Because unleash from version 2.0 migrates the database internally, with db-migrate, you need to make sure that all previous migrations for version 1 exist, so that Unleash does not try to create already existing tables.
How to check?
If you don't have a "migrations" table with 7 unique migrations you are affected by this.
How to fix?
Before starting unleash version 2 you have to run the SQL located under scripts/fix-migrations-version-1.sql
Caveat 2: databaseUrl (not databaseUri)
Using Unleash as a library and injecting your own config? Then you should know that we changed the databaseUri config param name to databaseUrl. This is to make sure the param is aligned with the environment variable DATABASE_URL and avoid multiple names for the same config param.
