Notable issues fixed

edit

Fixed: empty batches no longer incur processing overhead in the Java Execution Engine #11747
Fixed: when the Keystore is enabled, pipelines with many variable substitutions now load significantly faster #11772
Fixed: when x-pack Monitoring is configured with cloud_id, the monitoring pipeline now correctly resolves the hosts. #11800

Known issue

edit

Performance regression. A potential performance regression may affects some users. This issue can cause a slowdown on pipeline compilation when multiple pipelines are in use. We believe the issue was introduced in 7.7.0. This issue is currently being tracked and investigated in #12031

This issue seems to be affecting only big pipeline installations (that is, big pipeline definitions when multiple pipelines are defined). Symptoms include increased startup time and the appearance that Logstash is not responding to input events.

If you believe this issue is affecting you, we recommended that you downgrade to 7.6.2 while we continue to investigate and provide a resolution.

Plugins

edit

Elasticsearch Output - 10.4.2

[DOC] Added note about _type setting change from doc to _doc #884
Fixed default index value to use calendar year instead of the year corresponding to the ISO week year #927
