+Milestone number 2 of the upcoming 5.3.0 release of RDF4J is now available for download.
+
+RDF4J 5.3.0 is a minor release focusing on stability and getting the code ready for the next major release.
+
+### Notable changes in 5.3.0 M2
+
+ - SHACL validation can now be configured more precisely for inferred data ([GH-5676](https://github.com/eclipse-rdf4j/rdf4j/issues/5676)). If a shape (or global SHACL setting) disables inferred statements, underlying sails must emit inferred-aware callbacks by implementing `statementAdded(Statement, boolean inferred)` and `statementRemoved(Statement, boolean inferred)` in `SailConnectionListener`.
+ - Query builder fix: `FILTER NOT EXISTS` is now preserved when adding `GraphPatterns.filterNotExists(...)` to an empty `GraphPatterns.and()` ([GH-5561](https://github.com/eclipse-rdf4j/rdf4j/issues/5561)).
+ - Parser extension note: if you subclass `TupleExprBuilder` and override `createAnonVar()`, consider also overriding newer specialized methods used during parsing: `createAnonCollectionVar()`, `createAnonBnodeVar()`, `createAnonHavingVar()`, and `createAnonPathVar(boolean)`.
+ - `Var` remains extensible through SPI (as introduced in M1): use `Var.of(...)` factories, provide a custom `Var.Provider` (`newVar(...)` and optionally `cloneVar(...)`), and register via `META-INF/services/org.eclipse.rdf4j.query.algebra.Var$Provider` or the `org.eclipse.rdf4j.query.algebra.Var.provider` system property.
+ - Additional end-user fixes include support for refining JSON-LD `@context` ([GH-5573](https://github.com/eclipse-rdf4j/rdf4j/issues/5573)) and major LuceneSail transaction performance improvements ([GH-5291](https://github.com/eclipse-rdf4j/rdf4j/issues/5291)).
+
+### Deprecations since 5.2.0
+
+ - Legacy compare methods in `org.eclipse.rdf4j.query.algebra.evaluation.util.QueryEvaluationUtil`:
+   - `compare(Value, Value, CompareOp)`
+   - `compare(Value, Value, CompareOp, boolean)`
+   - `compareLiterals(Literal, Literal, CompareOp)`
+   - `compareLiterals(Literal, Literal, CompareOp, boolean)`
+ - Constructors in `org.eclipse.rdf4j.query.algebra.Var` are now deprecated (for removal), use `Var.of(...)` factories instead:
+   - `Var(String, Value, boolean, boolean)`
+   - `Var(String)`
+   - `Var(String, boolean)`
+   - `Var(String, Value)`
+   - `Var(String, Value, boolean)`
+ - Elasticsearch integration APIs deprecated for removal (preparation for Elasticsearch client upgrade):
+   - `org.eclipse.rdf4j.sail.elasticsearchstore.ElasticsearchStore`
+   - `org.eclipse.rdf4j.sail.elasticsearchstore.ElasticsearchStoreConnection`
+   - `org.eclipse.rdf4j.sail.elasticsearchstore.SingletonClientProvider`
+   - `org.eclipse.rdf4j.sail.elasticsearchstore.UserProvidedClientProvider`
+   - `org.eclipse.rdf4j.sail.elasticsearchstore.config.ElasticsearchStoreConfig`
+   - `org.eclipse.rdf4j.sail.elasticsearchstore.config.ElasticsearchStoreFactory`
+   - `org.eclipse.rdf4j.sail.elasticsearch.ElasticsearchBulkUpdater`
+   - `org.eclipse.rdf4j.sail.elasticsearch.ElasticsearchDocument`
+   - `org.eclipse.rdf4j.sail.elasticsearch.ElasticsearchDocumentDistance`
+   - `org.eclipse.rdf4j.sail.elasticsearch.ElasticsearchDocumentResult`
+   - `org.eclipse.rdf4j.sail.elasticsearch.ElasticsearchDocumentScore`
+   - `org.eclipse.rdf4j.sail.elasticsearch.ElasticsearchIndex`
+   - `org.eclipse.rdf4j.sail.elasticsearch.config.ElasticsearchSailConfig`
+   - `org.eclipse.rdf4j.sail.elasticsearch.config.ElasticsearchSailFactory`
+ - Solr integration APIs deprecated for removal:
+   - `org.eclipse.rdf4j.sail.solr.SolrBulkUpdater`
+   - `org.eclipse.rdf4j.sail.solr.SolrClientFactory`
+   - `org.eclipse.rdf4j.sail.solr.SolrDocumentDistance`
+   - `org.eclipse.rdf4j.sail.solr.SolrDocumentResult`
+   - `org.eclipse.rdf4j.sail.solr.SolrDocumentScore`
+   - `org.eclipse.rdf4j.sail.solr.SolrIndex`
+   - `org.eclipse.rdf4j.sail.solr.SolrSearchDocument`
+   - `org.eclipse.rdf4j.sail.solr.SolrSearchQuery`
+   - `org.eclipse.rdf4j.sail.solr.SolrUtil`
+   - `org.eclipse.rdf4j.sail.solr.client.cloud.Factory`
+   - `org.eclipse.rdf4j.sail.solr.client.embedded.Factory`
+   - `org.eclipse.rdf4j.sail.solr.client.http.Factory`
+   - `org.eclipse.rdf4j.sail.solr.config.SolrSailConfig`
+   - `org.eclipse.rdf4j.sail.solr.config.SolrSailFactory`
+
+This milestone build is not yet feature-complete, but we are putting it out to receive early feedback on all the improvements we have put in.
