Elasticsearch version 7.5.0edit
Also see Breaking changes in 7.5.
Known issuesedit
- Applying deletes or updates on an index after it has been shrunk may corrupt the index. In order to prevent this issue, it is recommended to stop shrinking read-write indices. For read-only indices, it is recommended to force-merge indices after shrinking, which significantly reduces the likeliness of this corruption in the case that deletes/updates would be applied by mistake. This bug is fixed in Elasticsearch 7.7 and later versions. More details can be found on the corresponding issue.
- Stop all transforms during a rolling upgrade to 7.5. If a transform is running during upgrade, the transform audit index might disappear. (issue: #49730)
-
Indices created in 6.x with
dateanddate_nanosfields using formats that are incompatible with java.time patterns will cause parsing errors, incorrect date calculations or wrong search results. https://github.com/elastic/elasticsearch/pull/52555 This is fixed in Elasticsearch 7.7 and later versions.
