+      title: Allow direct IO for BBQ rescoring
+      body: |-
+        BBQ rescoring performance can be drastically affected by the amount of available
+        off-heap RAM for use by the system page cache. When there is not enough off-heap RAM
+        to fit all the vector data in memory, BBQ search latencies can be affected by as much as 5000x.
+        Specifying the `vector.rescoring.directio=true` Java option on all vector search
+        nodes modifies rescoring to use direct IO, which eliminates these very high latencies
+        from searches in low-memory scenarios, at a cost of a reduction
+        in vector search performance for BBQ indices when the vectors do all fit in memory.
+
+        This option is released in 9.1 as a tech preview whilst we analyse its effect
+        for a variety of use cases.

+      title: Enable `exclude_source_vectors` by default for new indices
+      details: |-
+        The `exclude_source_vectors` setting is now enabled by default for newly created indices.
+        This means that vector fields (e.g., `dense_vector`) are no longer stored in the `_source` field
+        by default, although they remain fully accessible through search and retrieval operations.
+
+        Instead of being persisted in `_source`, vectors are now rehydrated on demand from the underlying
+        index structures when needed. This reduces index size and improves performance for typical vector
+        search workloads where the original vector values do not need to be part of the `_source`.
+
+        If your use case requires vector fields to be stored in `_source`, you can disable this behavior by
+        setting `exclude_source_vectors: false` at index creation time.
+      impact: |-
+        Vector fields will no longer be stored in `_source` by default for new indices. Applications or tools
+        that expect to see vector fields in `_source` (for raw document inspection)
+        may need to be updated or configured to explicitly retain vectors using `exclude_source_vectors: false`.
+
+        Retrieval of vector fields via search or the `_source` API remains fully supported.

+      body: |-
+        This provides a new index type called DiskBBQ (`bbq_disk`).
+        DiskBBQ is a cluster based format that provides:
+          - faster and cheaper indexing than HNSW
+          - Better behavior in lower memory environments (degrades linearly, not exponentially)
+          - Is near HNSW for QPS when the index is in memory
+
+        Current restrictions:
+          - only floating point values are allowed currently
+          - quantization is only to a single bit, so not recommended for low dimensionality vectors
+          - all other restrictions that exist for `dense_vector` fields still apply
+
+        To utilize the format, its just like any other:
+        [source,yaml]
+        ----------------------------
+        PUT vectors
+         {
+           "mappings": {
+             "properties": {
+               "vector": {"type": "dense_vector", "index_options": {"type": "disk_bbq"}
+             }
+           }
+         }
+        ----------------------------
+         Querying is just like any other field.
+        [source,yaml]
+        ----------------------------
+        POST vectors/_search{

+          }
+        }
+        ----------------------------
+        `num_candidates` can be used for tuning approximate nature of the search.
+        Or, more granular control can be provided by setting `visit_percentage` directly.

-::::{dropdown} Prevent LIMIT + MV_EXPAND before remote ENRICH
-Queries using LIMIT followed by MV_EXPAND before a remote ENRICH can produce incorrect results due to distributed execution semantics.
-These queries are now unsupported and produce an error. Example:
+::::{dropdown} Enable Failure Store for new logs data streams
+The [Failure Store](docs-content://manage-data/data-store/data-streams/failure-store.md) is now enabled by default for new logs data streams matching the pattern `logs-*-*`. This means that such data streams will now store invalid documents in a
+dedicated failure index instead of rejecting them, allowing better visibility and control over data quality issues without loosing data. This can be [enabled manually](docs-content://manage-data/data-store/data-streams/failure-store.md#set-up-failure-store-existing) for existing data streams. 
+Note: With the failure store enabled, the http response code clients receive when indexing invalid documents will change from `400 Bad Request` to `201 Created`, with an additional response attribute `"failure_store" : "used"`.
+::::
 
-```yaml
-FROM *:events | SORT @timestamp | LIMIT 2 | MV_EXPAND ip | ENRICH _remote:clientip_policy ON ip
-```
+::::{dropdown} Add support for Lookup Join on Multiple Fields
+Add support for Lookup Join on Multiple Fields e.g. FROM index1
+| LOOKUP JOIN lookup_index on field1, field2
+::::
 
-To avoid this error, reorder your query, for example by moving ENRICH earlier in the pipeline.
+::::{dropdown} Add support for expressions with LOOKUP JOIN in tech preview
+Enable Lookup Join on Expression Tech Preview
+FROM index1 | LOOKUP JOIN lookup_index on left_field1 > right_field1 AND left_field2 <= right_field2
 ::::
 
+::::{dropdown} Release DiskBBQ(`bbq_disk`) index type for `dense_vector` fields
+This provides a new index type called DiskBBQ (`bbq_disk`).
+DiskBBQ is a cluster based format that provides:
+  - faster and cheaper indexing than HNSW
+  - Better behavior in lower memory environments (degrades linearly, not exponentially)
+  - Is near HNSW for QPS when the index is in memory
+

+  - all other restrictions that exist for `dense_vector` fields still apply
+
+To utilize the format, its just like any other:
+[source,yaml]
+----------------------------
+PUT vectors
+ {
+   "mappings": {
+     "properties": {
+       "vector": {"type": "dense_vector", "index_options": {"type": "disk_bbq"}
+     }
+   }
+ }
+----------------------------
+ Querying is just like any other field.
+[source,yaml]
+----------------------------
+POST vectors/_search{
+  "query": {
+    "knn": {
+      "field": "vector",
+      "query_vector": <vector>,
+      "k": 3
+    }
+  }
+}
+----------------------------
+`num_candidates` can be used for tuning approximate nature of the search.
+Or, more granular control can be provided by setting `visit_percentage` directly.
+::::
+
+::::{dropdown} Enable INLINE STATS in non-snapshot builds
+This effectively releases INLINE STATS into tech preview.
+- Enable the lexing/grammar for INLINE STATS in non-snapshot builds.
+- Enable more tests with FORK and INLINE STATS
+::::
+
+::::{dropdown} Allow direct IO for BBQ rescoring
+BBQ rescoring performance can be drastically affected by the amount of available
+off-heap RAM for use by the system page cache. When there is not enough off-heap RAM
+to fit all the vector data in memory, BBQ search latencies can be affected by as much as 5000x.
+Specifying the `vector.rescoring.directio=true` Java option on all vector search
+nodes modifies rescoring to use direct IO, which eliminates these very high latencies
+from searches in low-memory scenarios, at a cost of a reduction
+in vector search performance for BBQ indices when the vectors do all fit in memory.
+
+This option is released in 9.1 as a tech preview whilst we analyse its effect
+for a variety of use cases.
+::::
+
+::::{dropdown} Add remote index support to LOOKUP JOIN
+Queries containing LOOKUP JOIN now can be preformed on cross-cluster indices, for example:
+[source,yaml]
+----------------------------
+FROM logs-*, remote:logs-* | LOOKUP JOIN clients on ip | SORT timestamp | LIMIT 100
+----------------------------
+::::
+
+::::{dropdown} New lucene 10.3.0 release
+- Improved performance for lexical, vector and primary-key searches
+- Use optimistic-with-checking KNN Query execution strategy in place of cross-thread global queue min-score checking. Improves performance and consistency.
+- Bulk scoring added for floating point vectors in HNSW. Improving query latency and indexing throughput
+- Multiple improvements to HNSW graph traversal and storage
+::::

+Queries using LIMIT followed by MV_EXPAND before a remote ENRICH can produce incorrect results due to distributed execution semantics.

+[source,yaml]
+----------------------------
+FROM *:events | SORT @timestamp | LIMIT 2 | MV_EXPAND ip | ENRICH _remote:clientip_policy ON ip

+To avoid this error, reorder your query, for example by moving ENRICH earlier in the pipeline.
