+
+## Version history
+
+The RDF4J REST API uses a single integer version numbering scheme. It does not follow semantic versioning. However, the implementations of the API client and server in RDF4J make a conscious effort to stay backward compatible with at least one previous protocol version.
+
+### 14: since RDF4J 4.3.0
+
+- Replaced usage of the `action` parameter on the `/transactions/{txnID}` endpoint with separate endpoints for each available action: `/transactions/{txnID}/add`, `/transactions/{txnID}/query`, and so on.
+- `action` parameter for transactions is deprecated
+
+### 13: since RDF4J 4.0.0
+
+- Removed support for the deprecated SYSTEM repository.
+
+### 12: since RDF4J 3.5.0
+
+- Added suport for the `prepare` transaction operation.
+
+### 11: since RDF4J 3.3.0
+
+- Added support for sending general transaction setting parameters.
+
+### 10: since RDF4J 3.1.0
+
+- Added support for retrieving a repository configuration.
+
+### 9: since RDF4J 3.0.0
+
+- Added direct API support for creating a new repository remotely and/or updating an existing repository's configuration. 
+- SYSTEM repository support is deprecated.

   title: RDF4J REST API
-  version: "10"
+  version: "14"
   description: |
     The RDF4J REST API is an HTTP protocol that covers a fully compliant implementation of the [SPARQL 1.1 Protocol W3C Recommendation](https://www.w3.org/TR/sparql11-protocol/). This ensures that RDF4J Server functions as a fully standard-compliant [SPARQL](https://www.w3.org/TR/sparql11-query/) endpoint.
 
     The RDF4J REST API additionally supports the [SPARQL 1.1 Graph Store HTTP Protocol W3C Recommendation](https://www.w3.org/TR/sparql11-http-rdf-update/). The RDF4J REST API extends the W3C standards in several aspects, the most important of which is database transaction management.
 
+    Version 13 was released as part of RDF4J 4.3.0. See the [REST API Changelog](/documentation/reference/rest-api/changelog) for details.
