Release Notes PDF
New Features
-
Includes bug fixes for Optimizer Hub 26.08.0.
-
Added the
gateway.compilerEngineUploadTimeoutHelm value (in seconds) to configure the timeout for compiler engine uploads through the Gateway. Increase it when the JVMs connect to Optimizer Hub over a high-latency network, where the default 30-second timeout can cause compilations to fail with an "Engine not found" error. See Network and Gateway Requirements.

-XX:+UseMultiTiering). Before this fix, a compilation stream could not be built from a profile recorded with multi tiering enabled, and the task executor failed withNo compilations were found in CoCa for profile …; stream can’t be built.
