You can no longer configure `xpack.searchable.snapshot.shared_cache.size` as a user setting in ESS on 7.13+ deployments. This PR removes the ESS icon from the related 8.0 breaking change for the setting.
It also clarifies the breaking change text to indicate that configuring the setting on non-frozen nodes will result in an error on startup.

#80556 reverted the deprecation of transient cluster settings. This replaces deprecation language in the docs with a warning/recommendation to avoid transient settings.
Closes#80557

Today if `libffi` cannot allocate pages of memory which are both
writeable and executable then it will attempt to write code to a
temporary file. Elasticsearch configures itself a suitable temporary
directory for use by JNA but by default `libffi` won't find this
directory and will try various other places. In certain configurations,
none of the other places that `libffi` tries are suitable. With older
versions of JNA this would result in a `SIGSEGV`; since #80617 the JVM
will exit with an exception.
With this commit we use the `LIBFFI_TMPDIR` environment variable to
configure `libffi` to use the same directory as JNA for its temporary
files if they are needed.

Adds a `force` parameter to the delete trained models API
which when set to `true` allows deletion of a model that
is referenced by ingest pipelines or has a started deployment.

This deprecates estimated_heap_memory_usage_bytes on model put and replaces it with model_size_bytes.
On GET, only model_size_bytes is returned unless v7 rest-api compatibility is requested.
For the ml/info API, only model_size_bytes is returned

Closes#76681. Our approach to using `scratch` for building Docker
images has caused problems at Docker Hub. Fix this situation by
removing the whole process of using scratch and instead bases the
default distribution on `almalinux:8.4-minimal`. Alma Linux is
binary-compatible with RHEL, and therefore very similar to UBI.
If the xpack.ml.use_auto_machine_memory_percent setting is true,
and xpack.ml.max_model_memory_limit is not set then
xpack.ml.max_model_memory_limit is now considered to be set to
the largest size that could be assigned in the cluster.
This functionality will be crucial for Cloud once the Elasticsearch
startup code is setting the Elasticsearch JVM heap size. Then the
Cloud code will no longer be able to accurately set
xpack.ml.max_model_memory_limit, so will not set it at all.
Instead the Cloud code will just set
xpack.ml.use_auto_machine_memory_percent and the ML code will
calculate the appropriate maximum model_memory_limit that should
be permitted.
This commit adds a new field deployment_stats that is optionally set for models that are deployed.
If a model does not have a deployment, it will be null.
Also, removes the get deployment stats API and makes the deployment stats action internal only.
This commit adds docs for the new `_knn_search` endpoint.
It focuses on being an API reference and is light on details in terms of how
exactly the kNN search works, and how the endpoint contrasts with
`script_score` queries. We plan to add a high-level guide on kNN search that
will explain this in depth.
Relates to #78473.
Currently, we don't support kNN search against fields in a `nested` mapping.
Before, we were checking this at search-time. This commit moves it earlier, so
you aren't even allowed to set `index: true` if the vector is in a nested
mapping. That way, users are aware of the limitation before they start to index
documents.
Relates to #78473.
When a deployment is started, we do not validate that the definition
documents are all present and not truncated. This commit adds a
validation on _start that prevents a bad state from occurring where the
deployment starts, but the model is incorrectly defined, or some unknown
error occurs to late in the deployment process.
We have a few leftover mentions of `zen` discovery, mostly for
historical/BwC reasons, which this commit removes.
Prior to this commit the default value for `discovery.type` was `zen`
but this was not written down anywhere or officially supported: the two
options were to set it to `single-node` or to omit it entirely. This
commit changes the default to `multi-node` and documents this.
