With https://github.com/elastic/stack-docs/pull/2495 merged, we no longer reuse breaking changes in the Stack Install/Upgrade guide. This removes the related `notable-breaking-changes[]` tags from the 8.9+ docs and updates the RN generator template. ## Out of scope With the removal of these tags, we may no longer need the `notable` property for changelog entries and can likely simplify the logic for the [BreakingChangesGenerator](https://github.com/elastic/elasticsearch/blob/main/build-tools-internal/src/main/java/org/elasticsearch/gradle/internal/release/BreakingChangesGenerator.java). Updating those files is outside the scope of this PR. I've opened https://github.com/elastic/elasticsearch/issues/98145 to track that work.

====
|
|
*Details* +
|
|
The following operating systems have reached their end of life and are no longer
|
|
supported by {es}:
|
|
|
|
* Amazon Linux
|
|
* CentOS 6
|
|
* Debian 8
|
|
* openSUSE Leap 42
|
|
* Oracle Enterprise Linux 6
|
|
* Ubuntu 16.04
|
|
|
|
We've also removed support for `SysV init`. No supported operating systems use
|
|
the `SysV init` process.

Ensure your nodes use a

.Java 17 is required.
|
|
[%collapsible]
|
|
====
|
|
*Details* +
|
|
Java 17 or higher is now required to run {es} and any of its command
|
|
line tools.
|
|
|
|
*Impact* +
|
|
Use Java 17 or higher. Attempts to run {es} 8.0 using earlier Java versions will
|
|
fail.
|
|
|
|
There is not yet a FIPS-certified security module for Java 17
|
|
that you can use when running {es} 8.0 in FIPS 140-2 mode.
|
|
If you run in FIPS 140-2 mode, you will either need to request an exception
|
|
from your security organization to upgrade to {es} 8.0,
|
|
or remain on {es} 7.x until Java 17 is certified.

|
|
the bundled JDK (preferable), or set `ES_JAVA_HOME`.
|
|
|
|
*Impact* +
|
|
Use the bundled JDK (preferable), or set `ES_JAVA_HOME`. `JAVA_HOME` will be
|
|
ignored.
