+- **Cloud Migration Tool**:\
   The `arangosync-migration` tool to move from on-premises to the cloud is not
   available anymore.
 
-- **Leader/Follower Deployment Mode**:
+- **Fast cluster restore procedure**:\
+  The procedure for speeding up _arangorestore_ in a cluster environment has been
+  removed from the documentation because the tool supports threading more
+  multiple collections (from version 3.3 onward) as well as single collections
+  (from version 3.8 onward using the non-enveloped format). For even faster
+  restoration with zero downtime, you can use _arangobackup_ for
+  [Hot Backups](../operations/backup-and-restore.md/#hot-backups).
+
+- **C# / .NET driver**:\
+  The [arangodb-net-standard](https://github.com/ArangoDB-Community/arangodb-net-standard)
+  driver is not an official ArangoDB driver anymore but may still be maintained
+  by the community.
+
+- **Leader/Follower Deployment Mode**:\
   The Leader/Follower deployment mode is deprecated and already removed from
   documentation. Active Failover and OneShard databases in clusters are better
   alternatives.
 
-- **Skiplist and hash indexes**:
+- **Skiplist and hash indexes**:\
   Skiplist and hash indexes have been deprecated in 3.9 and will be removed in a 
   future version of ArangoDB. Currently, they are an alias for a
   [persistent index](../indexes-and-search/indexing/basics.md#persistent-index).
 
-- **Bundled NPM modules**:
+- **Bundled NPM modules**:\
   The bundled NPM modules `aqb`, `chai`, `dedent`, `error-stack-parser`,
   `graphql-sync`, `highlight.js`, `i` (inflect), `iconv-lite`, `joi`,
   `js-yaml`, `lodash`, `minimatch`, `qs`, `semver`, `sinon`, and `timezone`
   have been deprecated in 3.9 and will be removed in a future version of ArangoDB.
   If you want to use NPM modules in your Foxx service, please refer to the
   [Foxx guide](../develop/foxx-microservices/guides/using-node-modules.md).
 
-- **Batch Requests API**:
+- **Batch Requests API**:\
   The [batch request REST API](../develop/http-api/batch-requests.md) is deprecated and will be 
   removed in a future version. Instead of using this API, please use the 
   [HTTP interface for documents](../develop/http-api/documents.md#multiple-document-operations)
   that can insert, update, replace or remove arrays of documents.
 
-- **PUT method in Cursor API**:
+- **PUT method in Cursor API**:\
   The HTTP endpoint `PUT /_api/cursor/<cursor-id>` in the
   [Cursor REST API](../develop/http-api/queries/aql-queries.md) is deprecated and will be
   removed in a future version. Please use the drop-in replacement
   `POST /_api/cursor/<cursor-id>` instead. The POST endpoint is functionally
   equivalent to the PUT endpoint, but does not violate idempotency requirements
   prescribed by the [HTTP specification](https://tools.ietf.org/html/rfc7231#section-4.2).
 
-- **Fulltext indexes**:
+- **Fulltext indexes**:\
   The fulltext index type is deprecated from version 3.10 onwards.
   It is recommended to use [ArangoSearch](../indexes-and-search/arangosearch/_index.md) for advanced full-text search capabilities.
 
-- **Simple Queries**: Idiomatic interface in arangosh to perform trivial queries.
+- **Simple Queries**:\
+  Idiomatic interface in arangosh to perform trivial queries.
   They are superseded by [AQL queries](../aql/_index.md), which can also
   be run in arangosh. AQL is a language on its own and way more powerful than
   *Simple Queries* could ever be. In fact, the (still supported) *Simple Queries*
   are translated internally to AQL, then the AQL query is optimized and run
   against the database in recent versions, because of better performance and
   reduced maintenance complexity.
 
-- **Accessing collections by ID instead of by name**:
+- **Accessing collections by ID instead of by name**:\
   Accessing collections by their internal ID instead of accessing them by name
   is deprecated and highly discouraged. This functionality may be removed in
   future versions of ArangoDB.
 
-- **Old metrics REST API**:
+- **Old metrics REST API**:\
   The old metrics API under `/_admin/metrics` is deprecated and replaced by
   a new one under `/_admin/metrics/v2` from version 3.8.0 on. This step was
   necessary because the old API did not follow quite a few Prometheus
   guidelines for metrics.
 
-- **Statistics REST API**:
+- **Statistics REST API**:\
   The endpoints `/_admin/statistics` and `/_admin/statistics-description`
   are deprecated in favor of the new metrics API under `/_admin/metrics/v2`.
   The metrics API provides a lot more information than the statistics API, so
   it is much more useful.
 
-- **Database target version REST API**:
+- **Database target version REST API**:\
   The `GET /_admin/database/target-version` endpoint is deprecated in favor of the
   more general version API with the endpoint `GET /_api/version`. The endpoint may be
   removed in a future version of ArangoDB.
 
-- **Replication logger-follow REST API**:

   The endpoint `/_api/replication/logger-follow` is deprecated since 3.4.0 and
