This section discusses the changes that you need to be aware of when migrating
your application to {es} 8.0.

Remove `nGram` and `edgeNGram` token filter names (#38911) In #30209 we deprecated the camel case `nGram` filter name in favour of `ngram` and did the same for `edgeNGram` and `edge_ngram`. Using these names has been deprecated since 6.4 and is issuing deprecation warnings since then. I think we can remove these filters in 8.0. In a backport of this PR I would change what was a dreprecation warning from 6.4. to an error starting with new indices created in 7.0.

coming[8.0.0]
Move some token filter migration notes (#39072) The removal of the "nGram" and "edgeNGram" token filter was filed in a new migrate_8_0/mappings.asciidoc document but it should better be in an analysis.asciidoc section and file.

Remove Zen1 (#39466) Removes all traces of Zen1 from the code base. Some of these commits will also be backported to 7.0/7.x (#39470) as the cluster.coordination package was making use of some things in discovery.zen and we want to keep 7.x as close as possible to master.

Unify blob store compress setting (#39346) Blob store compression was all implemented generally, except reading the setting for it. Moved the setting to BlobStoreRepository to unify this. Also removed deprecated env setting 'repositories.fs.compress'. This is a follow up on #39073

Remove obsolete security settings (#40496) Removes the deprecated accept_default_password setting. This setting become redundant when default passwords were removed from 6.0, but the setting was kept for BWC. Removes native role store cache settings. These have been unused since 5.2 but were kept for BWC.

==== Indices created before 7.0
Enforce Completion Context Limit (#38675) This change adds a limit to the number of completion contexts that a completion field can define. Closes #32741
2019-02-18 19:51:40 +08:00
Elasticsearch 8.0 can read indices created in version 7.0 or above. An
Elasticsearch 8.0 node will not start in the presence of indices created in a
version of Elasticsearch before 7.0.
[IMPORTANT]
.Reindex indices from Elasticsearch 6.x or before
=========================================
Indices created in Elasticsearch 6.x or before will need to be reindexed with
Elasticsearch 7.x in order to be readable by Elasticsearch 8.x.
