message: docs: Document new features and config changes for 2.0.0
diff: # Community Solid Server release notes
  +## v2.0.0
  +### New features
  +- Pod owners always have Control access to resources stored in their Pod.
  +- The server now offers a one-time setup upon first boot.
  + This can be accessed by going to `/setup`.
  + Configurations with a persistent backend enforce setup before the server can be used,
  + preventing unintended modifications in the backend.
  + These have corresponding `*-no-setup.json` files where setup is disabled,
  + so the pre-v2.0 behavior is still available.
  +- `ETag`, `Last-Modified`, `If-None-Match`, and related conditional headers are supported.
  +- `PATCH`ing containers is now supported.
  +- `PUT`/`POST` requests with empty bodies are supported.
  +- WebACL authorization supports groups.
  +- IDP components (registration, login, etc.) fully support JSON input and output.
  +- There is a new configuration `sparql-file-storage.json` to have a SPARQL backend with file storage.
  + `sparql-file-storage.json`.
  +- A server can be set up to restrict access to IDP components using WebACL.
  + A consequence of this is that IDP components are only accessible using a trailing slash.
  + E.g., `/idp/register/` works, `/idp/register` will error.
  +
  +### Configuration changes
  +You might need to make changes to your v1 configuration if you use a custom config.
  +
  +The following changes pertain to the imports in the default configs:
  +- There are 2 new configuration options that for which a valid option needs to be imported:
  + - `/app/setup` determines how and if setup should be enabled.
  + - `/identity/access` determines if IDP access (e.g., registration) should be restricted
  +- The `/app/init/default.json` configuration no longer initializes the root container.
  + This behaviour has been moved to the other options for `/app/init`.
  +- `/ldp/permissions` changed to `/ldp/modes` and only has a default option now.
  +
  +The following changes are relevant for v1 custom configs that replaced certain features.
  +The path indicates which JSON-LD files were impacted by the change.
  +- `IdentityProviderHttpHandler` and `InteractionRoute` arguments have changed substantially.
  + - `/identity/handler/default.json`
  + - `/identity/handler/interaction/*`
  + - `/identity/registration/*`.
  +- All internal storage is now stored in the `/.internal/` container.
  + - `/storage/key-value/resource-store.json`.
  +- Patching related classes have changed.
  + - `/storage/middleware/stores/patching.json`.
  +- `BasicRequestParser` now needs a `conditionsParser` argument.
  + - `/ldp/handler/components/request-parser.json`.
  +- `LinkTypeParser` has been renamed to `LinkRelParser` and now takes mappings as input.
  + - `/ldp/metadata-parser/*`
  +- `ComposedAuxiliaryStrategy` `isRootRequired` has been renamed to `requiredInRoot`.
  + - `/util/auxiliary/strategies/acl.json`.
  +- Many changes to authentication and authorization structure.
  + - Config `/ldp/authentication/*` and `/ldp/authorization/*`.
  +- All `HttpHandler`s have been changed.
  + - `/app/setup/handlers/setup.json`
  + - `/http/handler/default.json`
  + - `/identity/handler/default.json`
  + - `/ldp/handler/default.json`.

  ## v1.1.0
  -New features:
  +### New features
  - The `ConstantConverter` can now filter on media type using the `enabledMediaRanges` and `disabledMediaRanges` options. That way, the server can be configured to bypass a default UI when accessing images or PDF documents.
