-[[stored_fields_are_compressed_with_zstandard_instead_of_lz4_deflate]]
-=== Stored fields are now compressed with ZStandard instead of LZ4/DEFLATE
-Stored fields are now compressed by splitting documents into blocks, which
-are then compressed independently with ZStandard. `index.codec: default`
-(default) uses blocks of at most 14kB or 128 documents compressed with level
-0, while `index.codec: best_compression` uses blocks of at most 240kB or
-2048 documents compressed at level 3. On most datasets that we tested
-against, this yielded storage improvements in the order of 10%, slightly
-faster indexing and similar retrieval latencies.

-=== Stricter failure handling in multi-repo get-snapshots request handling
-If a multi-repo get-snapshots request encounters a failure in one of the
-targeted repositories then earlier versions of Elasticsearch would proceed
-as if the faulty repository did not exist, except for a per-repository
-failure report in a separate section of the response body. This makes it
-impossible to paginate the results properly in the presence of failures. In
-versions 8.15.0 and later this API's failure handling behaviour has been
-made stricter, reporting an overall failure if any targeted repository's
-contents cannot be listed.

-New int4 (half-byte) scalar quantization support via two knew index types: `int4_hnsw` and `int4_flat`.
-This gives an 8x reduction from `float32` with some accuracy loss. In addition to less memory required, this
-improves query and merge speed significantly when compared to raw vectors.

-[[adds_new_bit_element_type_for_dense_vectors]]
-=== Adds new `bit` `element_type` for `dense_vectors`
-This adds `bit` vector support by adding `element_type: bit` for
-vectors. This new element type works for indexed and non-indexed
-vectors. Additionally, it works with `hnsw` and `flat` index types. No
-quantization based codec works with this element type, this is
-consistent with `byte` vectors.
-
-`bit` vectors accept up to `32768` dimensions in size and expect vectors
-that are being indexed to be encoded either as a hexidecimal string or a
-`byte[]` array where each element of the `byte` array represents `8`
-bits of the vector.
-
-`bit` vectors support script usage and regular query usage. When
-indexed, all comparisons done are `xor` and `popcount` summations (aka,
-hamming distance), and the scores are transformed and normalized given
-the vector dimensions.
-
-For scripts, `l1norm` is the same as `hamming` distance and `l2norm` is
-`sqrt(l1norm)`. `dotProduct` and `cosineSimilarity` are not supported. 
-
-Note, the dimensions expected by this element_type are always to be
-divisible by `8`, and the `byte[]` vectors provided for index must be
-have size `dim/8` size, where each byte element represents `8` bits of
-the vectors.

-[[new_custom_parser_for_iso_8601_datetimes]]
-=== New custom parser for ISO-8601 datetimes
-This introduces a new custom parser for ISO-8601 datetimes, for the `iso8601`, `strict_date_optional_time`, and
-`strict_date_optional_time_nanos` built-in date formats. This provides a performance improvement over the
-default Java date-time parsing. Whilst it maintains much of the same behaviour,
-the new parser does not accept nonsensical date-time strings that have multiple fractional seconds fields
-or multiple timezone specifiers. If the new parser fails to parse a string, it will then use the previous parser
-to parse it. If a large proportion of the input data consists of these invalid strings, this may cause
-a small performance degradation. If you wish to force the use of the old parsers regardless,
-set the JVM property `es.datetime.java_time_parsers=true` on all ES nodes.

-=== New custom parser for more ISO-8601 date formats
-Following on from #106486, this extends the custom ISO-8601 datetime parser to cover the `strict_year`,
-`strict_year_month`, `strict_date_time`, `strict_date_time_no_millis`, `strict_date_hour_minute_second`,
-`strict_date_hour_minute_second_millis`, and `strict_date_hour_minute_second_fraction` date formats.
-As before, the parser will use the existing java.time parser if there are parsing issues, and the
-`es.datetime.java_time_parsers=true` JVM property will force the use of the old parsers regardless.
