-  details: edge_ngram will no longer accept the side parameter.
-  impact: Users will need to update any usage of edge_ngram token filter that utilizes `side`. If the `back` value was used, they can achieve the same behavior by using the `reverse` token filter.

-    In earlier versions of {es} the `cluster.routing.allocation.allow_rebalance` setting defaults to
-    `indices_all_active` which blocks all rebalancing moves while the cluster is in `yellow` or `red` health. This was
-    appropriate for the legacy allocator which might do too many rebalancing moves otherwise. Today's allocator has
-    better support for rebalancing a cluster that is not in `green` health, and expects to be able to rebalance some
-    shards away from over-full nodes to avoid allocating shards to undesirable locations in the first place. From
-    version 8.16 `allow_rebalance` setting defaults to `always` unless the legacy allocator is explicitly enabled.

-highlight:
-  title: "ESQL: Multi-value fields supported in Geospatial predicates"
-  body: |-
-    Supporting multi-value fields in `WHERE` predicates is a challenge due to not knowing whether `ALL` or `ANY`
-    of the values in the field should pass the predicate.
-    For example, should the field `age:[10,30]` pass the predicate `WHERE age>20` or not?
-    This ambiguity does not exist with the spatial predicates
-    `ST_INTERSECTS` and `ST_DISJOINT`, because the choice between `ANY` or `ALL`
-    is implied by the predicate itself.
-    Consider a predicate checking a field named `location` against a test geometry named `shape`:
-
-    * `ST_INTERSECTS(field, shape)` - true if `ANY` value can intersect the shape
-    * `ST_DISJOINT(field, shape)` - true only if `ALL` values are disjoint from the shape
-
-    This works even if the shape argument is itself a complex or compound geometry.
-
-    Similar logic exists for `ST_CONTAINS` and `ST_WITHIN` predicates, but these are not as easily solved
-    with `ANY` or `ALL`, because a collection of geometries contains another collection if each of the contained
-    geometries is within at least one of the containing geometries. Evaluating this requires that the multi-value
-    field is first combined into a single geometry before performing the predicate check.
-
-    * `ST_CONTAINS(field, shape)` - true if the combined geometry contains the shape
-    * `ST_WITHIN(field, shape)` - true if the combined geometry is within the shape
-  notable: false

-area: Data streams

-breaking:
-  title: Update data stream lifecycle telemetry to track global retention
-  area: REST API
-  details: |-
-    In this release we introduced global retention settings that fulfil the following criteria:
-
-    - a data stream managed by the data stream lifecycle,
-    - a data stream that is not an internal data stream.
-
-    As a result, we defined different types of retention:
-
-    - **data retention**: the retention configured on data stream level by the data stream user or owner
-    - **default global retention:** the retention configured by an admin on a cluster level and applied to any
-    data stream that doesn't have data retention and fulfils the criteria.
-    - **max global retention:** the retention configured by an admin to guard against having long retention periods.
-    Any data stream that fulfills the criteria will adhere to the data retention unless it exceeds the max retention,
-    in which case the max global retention applies.
-    - **effective retention:** the retention that applies on the data stream that fulfill the criteria at a given moment
-    in time. It takes into consideration all the retention above and resolves it to the retention that will take effect.
-
-    Considering the above changes, having a field named `retention` in the usage API was confusing. For this reason, we
-    renamed it to `data_retention` and added telemetry about the other configurations too.
-  impact: Users that use the field `data_lifecycle.retention` should use the `data_lifecycle.data_retention`
-  notable: false

-  title: Enable ZStandard compression for indices with index.codec set to best_compression
-  body: |-
-    Before DEFLATE compression was used to compress stored fields in indices with index.codec index setting set to
-    best_compression, with this change ZStandard is used as compression algorithm to stored fields for indices with
-    index.codec index setting set to best_compression. The usage ZStandard results in less storage usage with a
-    similar indexing throughput depending on what options are used. Experiments with indexing logs have shown that
-    ZStandard offers ~12% lower storage usage and a ~14% higher indexing throughput compared to DEFLATE.

-  title: Enhance SORT push-down to Lucene to cover references to fields and ST_DISTANCE function
-  body: |-
-    The most used and likely most valuable geospatial search query in Elasticsearch is the sorted proximity search,
-    finding items within a certain distance of a point of interest and sorting the results by distance.
-    This has been possible in ES|QL since 8.15.0, but the sorting was done in-memory, not pushed down to Lucene.
-    Now the sorting is pushed down to Lucene, which results in a significant performance improvement.
-
-    Queries that perform both filtering and sorting on distance are supported. For example:
-
-    [source,esql]
-    ----
-    FROM test
-    | EVAL distance = ST_DISTANCE(location, TO_GEOPOINT("POINT(37.7749, -122.4194)"))
-    | WHERE distance < 1000000
-    | SORT distance ASC, name DESC
-    | LIMIT 10
-    ----
-
-    In addition, the support for sorting on EVAL expressions has been extended to cover references to fields:
-
-    [source,esql]
-    ----
-    FROM test
-    | EVAL ref = field
-    | SORT ref ASC
-    | LIMIT 10

-breaking:
-  title: JDK locale database change
-  area: Mapping
-  details: |
-    {es} 8.16 changes the version of the JDK that is included from version 22 to version 23. This changes the locale database that is used by Elasticsearch from the COMPAT database to the CLDR database. This change can cause significant differences to the textual date formats accepted by Elasticsearch, and to calculated week-dates.
-
-    If you run {es} 8.16 on JDK version 22 or below, it will use the COMPAT locale database to match the behavior of 8.15. However, starting with {es} 9.0, {es} will use the CLDR database regardless of JDK version it is run on.
-  impact: |
-    This affects you if you use custom date formats using textual or week-date field specifiers. If you use date fields or calculated week-dates that change between the COMPAT and CLDR databases, then this change will cause Elasticsearch to reject previously valid date fields as invalid data. You might need to modify your ingest or output integration code to account for the differences between these two JDK versions.
-
-    Starting in version 8.15.2, Elasticsearch will log deprecation warnings if you are using date format specifiers that might change on upgrading to JDK 23. These warnings are visible in Kibana.
-
-    For detailed guidance, refer to <<custom-date-format-locales,Differences in locale information between JDK versions>> and the https://ela.st/jdk-23-locales[Elastic blog].

-summary: Adding breaking change entry for retrievers
-area: Search
-type: breaking
-issues: []
-breaking:
-  title: Reworking RRF retriever to be evaluated during rewrite phase
-  area: REST API
-  details: |-
-    In this release (8.16), we have introduced major changes to the retrievers framework 
-    and how they can be evaluated, focusing mainly on compound retrievers 
-    like `rrf` and `text_similarity_reranker`, which allowed us to support full 
-    composability (i.e. any retriever can be nested under any compound retriever), 
-    as well as supporting additional search features like collapsing, explaining, 
-    aggregations, and highlighting.
-    
-    To ensure consistency, and given that this rework is not available until 8.16, 
-    `rrf` and `text_similarity_reranker`  retriever queries would now  
-    throw an exception in a mixed cluster scenario, where there are nodes 
-    both in current or later (i.e. >= 8.16) and previous ( <= 8.15) versions.
-    
-    As part of the rework, we have also removed the `_rank` property from 
-    the responses of an `rrf` retriever.
-  impact: |-
-    - Users will not be able to use the `rrf` and `text_similarity_reranker` retrievers in a mixed cluster scenario
-    with previous releases (i.e. prior to 8.16), and the request will throw an `IllegalArgumentException`.
-    - `_rank` has now been removed from the output of the `rrf` retrievers so trying to directly parse the field
-    will throw an exception
-  notable: false

-{es} 8.16 changes the version of the JDK that is included from version 22 to version 23. This changes
-the locale database that is used by Elasticsearch from the _COMPAT_ database to the _CLDR_ database.
-This can result in significant changes to custom textual date field formats,

+.JDK locale database change
+[%collapsible]
+====
+*Details* +
+{es} 8.16 changes the version of the JDK that is included from version 22 to version 23. This changes the locale database that is used by Elasticsearch from the COMPAT database to the CLDR database. This change can cause significant differences to the textual date formats accepted by Elasticsearch, and to calculated week-dates.
+
+If you run {es} 8.16 on JDK version 22 or below, it will use the COMPAT locale database to match the behavior of 8.15. However, starting with {es} 9.0, {es} will use the CLDR database regardless of JDK version it is run on.
+
+*Impact* +
+This affects you if you use custom date formats using textual or week-date field specifiers. If you use date fields or calculated week-dates that change between the COMPAT and CLDR databases, then this change will cause Elasticsearch to reject previously valid date fields as invalid data. You might need to modify your ingest or output integration code to account for the differences between these two JDK versions.
+
+Starting in version 8.15.2, Elasticsearch will log deprecation warnings if you are using date format specifiers that might change on upgrading to JDK 23. These warnings are visible in Kibana.
+
+For detailed guidance, refer to <<custom-date-format-locales,Differences in locale information between JDK versions>> and the https://ela.st/jdk-23-locales[Elastic blog].

+[[reworking_rrf_retriever_to_be_evaluated_during_rewrite_phase]]
+.Reworking RRF retriever to be evaluated during rewrite phase
+[%collapsible]
+====
+*Details* +
+In this release (8.16), we have introduced major changes to the retrievers framework 
+and how they can be evaluated, focusing mainly on compound retrievers 
+like `rrf` and `text_similarity_reranker`, which allowed us to support full 
+composability (i.e. any retriever can be nested under any compound retriever), 
+as well as supporting additional search features like collapsing, explaining, 
+aggregations, and highlighting.
+
+To ensure consistency, and given that this rework is not available until 8.16, 
+`rrf` and `text_similarity_reranker`  retriever queries would now  
+throw an exception in a mixed cluster scenario, where there are nodes 
+both in current or later (i.e. >= 8.16) and previous ( <= 8.15) versions.
+
+As part of the rework, we have also removed the `_rank` property from 
+the responses of an `rrf` retriever.
+
+*Impact* +
+- Users will not be able to use the `rrf` and `text_similarity_reranker` retrievers in a mixed cluster scenario
+with previous releases (i.e. prior to 8.16), and the request will throw an `IllegalArgumentException`.
+- `_rank` has now been removed from the output of the `rrf` retrievers so trying to directly parse the field
+will throw an exception
+====
+
+[[update_data_stream_lifecycle_telemetry_to_track_global_retention]]
+.Update data stream lifecycle telemetry to track global retention
+[%collapsible]
+====
+*Details* +
+In this release we introduced global retention settings that fulfil the following criteria:
+
+- a data stream managed by the data stream lifecycle,
+- a data stream that is not an internal data stream.
+
+As a result, we defined different types of retention:
+
+- **data retention**: the retention configured on data stream level by the data stream user or owner
+- **default global retention:** the retention configured by an admin on a cluster level and applied to any
+data stream that doesn't have data retention and fulfils the criteria.
+- **max global retention:** the retention configured by an admin to guard against having long retention periods.
+Any data stream that fulfills the criteria will adhere to the data retention unless it exceeds the max retention,
+in which case the max global retention applies.
+- **effective retention:** the retention that applies on the data stream that fulfill the criteria at a given moment
+in time. It takes into consideration all the retention above and resolves it to the retention that will take effect.
+
+Considering the above changes, having a field named `retention` in the usage API was confusing. For this reason, we
+renamed it to `data_retention` and added telemetry about the other configurations too.
+
+*Impact* +
+Users that use the field `data_lifecycle.retention` should use the `data_lifecycle.data_retention`

+[[deprecated-8.16]]
+=== Deprecations
+
+The following functionality has been deprecated in {es} 8.16
+and will be removed in a future version.
+While this won't have an immediate impact on your applications,
+we strongly encourage you to take the described steps to update your code
+after upgrading to 8.16.
+
+To find out if you are using any deprecated functionality,
+enable <<deprecation-logging, deprecation logging>>.

+[%collapsible]
+====
+*Details* +
+edge_ngram will no longer accept the side parameter.

+*Impact* +
+Users will need to update any usage of edge_ngram token filter that utilizes `side`. If the `back` value was used, they can achieve the same behavior by using the `reverse` token filter.

+[[deprecations_816_crud]]
+==== CRUD deprecations
+
+[[deprecate_dot_prefixed_indices_composable_template_index_patterns]]
+.Deprecate dot-prefixed indices and composable template index patterns
+[%collapsible]
+====
+*Details* +
+Indices beginning with a dot '.' are reserved for system and internal indices, and should not be used by and end-user. Additionally, composable index templates that contain patterns for dot-prefixed indices should also be avoided, as these patterns are meant for internal use only. In a future Elasticsearch version, creation of these dot-prefixed indices will no longer be allowed.
+
+*Impact* +
+Requests performing an action that would create an index beginning with a dot (indexing a document, manual creation, reindex), or creating an index template with index patterns beginning with a dot, will contain a deprecation header warning about dot-prefixed indices in the response.

+[%collapsible]
+====
+*Details* +
+Search API parameter `sub_searches` will no longer be a supported and will be removed in future releases. Similarly, `rrf` can only be used through the specified `retriever` and no longer though the `rank` parameter
+
+*Impact* +
+Requests specifying rrf through `rank` and/or `sub_searches` elements will be disallowed in a future version. Users should instead utilize the new `retriever` parameter.
+====
+
+[[deprecate_legacy_params_from_range_query]]
+.Deprecate legacy params from range query
+[%collapsible]
+====
+*Details* +
+Range query will not longer accept `to`, `from`, `include_lower`, and `include_upper` parameters.
+
+*Impact* +
+Instead use `gt`, `gte`, `lt` and `lte` parameters.

-If you run {es} 8.16 on JDK version 22 or below, it will use the _COMPAT_ locale database
-to match the behavior of 8.15. However, please note that starting with {es} 9.0,
-{es} will use the _CLDR_ database regardless of JDK version it is run on.

-=== Always allow rebalancing by default
-In earlier versions of {es} the `cluster.routing.allocation.allow_rebalance` setting defaults to
-`indices_all_active` which blocks all rebalancing moves while the cluster is in `yellow` or `red` health. This was
-appropriate for the legacy allocator which might do too many rebalancing moves otherwise. Today's allocator has
-better support for rebalancing a cluster that is not in `green` health, and expects to be able to rebalance some
-shards away from over-full nodes to avoid allocating shards to undesirable locations in the first place. From
-version 8.16 `allow_rebalance` setting defaults to `always` unless the legacy allocator is explicitly enabled.

-=== Enable ZStandard compression for indices with index.codec set to best_compression
-Before DEFLATE compression was used to compress stored fields in indices with index.codec index setting set to
-best_compression, with this change ZStandard is used as compression algorithm to stored fields for indices with
-index.codec index setting set to best_compression. The usage ZStandard results in less storage usage with a

-ZStandard offers ~12% lower storage usage and a ~14% higher indexing throughput compared to DEFLATE.

-[[esql_multi_value_fields_supported_in_geospatial_predicates]]
-=== ESQL: Multi-value fields supported in Geospatial predicates
-Supporting multi-value fields in `WHERE` predicates is a challenge due to not knowing whether `ALL` or `ANY`
-of the values in the field should pass the predicate.
-For example, should the field `age:[10,30]` pass the predicate `WHERE age>20` or not?
-This ambiguity does not exist with the spatial predicates
-`ST_INTERSECTS` and `ST_DISJOINT`, because the choice between `ANY` or `ALL`
-is implied by the predicate itself.
-Consider a predicate checking a field named `location` against a test geometry named `shape`:
-
-* `ST_INTERSECTS(field, shape)` - true if `ANY` value can intersect the shape
-* `ST_DISJOINT(field, shape)` - true only if `ALL` values are disjoint from the shape
-
-This works even if the shape argument is itself a complex or compound geometry.
-
-Similar logic exists for `ST_CONTAINS` and `ST_WITHIN` predicates, but these are not as easily solved
-with `ANY` or `ALL`, because a collection of geometries contains another collection if each of the contained
-geometries is within at least one of the containing geometries. Evaluating this requires that the multi-value
-field is first combined into a single geometry before performing the predicate check.
-
-* `ST_CONTAINS(field, shape)` - true if the combined geometry contains the shape
-* `ST_WITHIN(field, shape)` - true if the combined geometry is within the shape

-[[enhance_sort_push_down_to_lucene_to_cover_references_to_fields_st_distance_function]]
-=== Enhance SORT push-down to Lucene to cover references to fields and ST_DISTANCE function
-The most used and likely most valuable geospatial search query in Elasticsearch is the sorted proximity search,
-finding items within a certain distance of a point of interest and sorting the results by distance.
-This has been possible in ES|QL since 8.15.0, but the sorting was done in-memory, not pushed down to Lucene.
-Now the sorting is pushed down to Lucene, which results in a significant performance improvement.
-
-Queries that perform both filtering and sorting on distance are supported. For example:
-
-[source,esql]
-----
-FROM test
-| EVAL distance = ST_DISTANCE(location, TO_GEOPOINT("POINT(37.7749, -122.4194)"))
-| WHERE distance < 1000000
-| SORT distance ASC, name DESC
-| LIMIT 10
-----
-
-In addition, the support for sorting on EVAL expressions has been extended to cover references to fields:
-
-[source,esql]
-----
-FROM test
-| EVAL ref = field
-| SORT ref ASC
-| LIMIT 10
