Part of the recurring compatibility testing, Elasticsearch 8.13.x has been added to the compatibility matrix to the corresponding Liferay versions.
Note: Compatibility with newer Elasticsearch minor versions is always tested in two ways:
Latest-Latest: Testing the latest Liferay version with the latest available minor version of Elasticsearch → e.g. Master/2024.Q2 + Elasticsearch 8.13
Minimum-Latest: Testing the minimum Liferay version where Elasticsearch 8 compatibility was first made available with the latest minor version of Elasticsearch → DXP 7.4 U81/DXP 7.3 U31 + Elasticsearch 8.13
This way we can not only provide compatibility for the latest Liferay versions, but also backwards compatibility, allowing a broader customer base and deployments to operate their stack with an up-to-date search engine version.
As Elasticsearch is usually released a new Minor version roughly every two months, this is a recurring process and a planned activity for our team.
