This section discusses the changes that you need to be aware of to migrate
|
|
your application to {version}. For more information about what's new in this
|
|
release, see the <<release-highlights>> and <<es-release-notes>>.
|
|
|
|
As {es} introduces new features and improves existing ones,
|
|
the changes sometimes make older settings, APIs, and parameters obsolete.
|
|
The obsolete functionality is typically deprecated in a minor release and
|
|
removed in the subsequent major release.
|
|
This enables applications to continue working unchanged
|
|
across most minor version upgrades.
|
|
Breaking changes introduced in minor releases are
|
|
generally limited to critical security fixes
|
|
and bug fixes that correct unintended behavior.
|
|
|
|
To get the most out of {es} and facilitate future upgrades,
|
|
we strongly encourage migrating
|
|
away from using deprecated functionality as soon as possible.
|
|
|
|
To give you insight into what deprecated features you're using, {es}:
|
|
|
|
- Returns a `Warn` HTTP header whenever you
|
|
submit a request that uses deprecated functionality.
|
|
- <<deprecation-logging, Logs deprecation warnings>> when
|
|
deprecated functionality is used.
|
|
- <<migration-api-deprecation, Provides a deprecation info API>>
|
|
that scans a cluster's configuration
|
|
and mappings for deprecated functionality.
|
|
|
|
For more information about {minor-version},
|
|
see the <<release-highlights>> and <<es-release-notes>>.
|
|
