Optimizer Hub 26.08.1

Release Date: October 13, 2026 - Release Notes PDF

New Features

  • Includes bug fixes for Optimizer Hub 26.08.0.

  • Added the gateway.compilerEngineUploadTimeout Helm 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.

Bug Fixes

  • Fix for compilation streaming when used with compilation multi tiering (-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 with No compilations were found in CoCa for profile …​; stream can’t be built.
