Breaking Changes

• Upgrading the minimum Java version to Java 17, which means users will need to upgrade their Java installation to at least Java 17. The docker versions relying on jdk16 will no longer be published, so docker users explicitly referencing the jdk16 build need to update their package to reference jdk17, as tags develop-jdk16, develop-jdk16-arm64, latest-jdk16 will no longer be updated.
• Users who make heavy use of API calls to fetch non finalized states data other than head may wish to adjust the states-cache if they see excessive regeneration of state messages. This can be accomplished via the --Xstore-state-cache-size, which previously defaulted to 160.

Additions and Improvements

• Introduce --exchange-capabilities-monitoring-enabled parameter. If enabled, EL will be queried periodically for the Engine API methods it supports. If incompatibility is detected, a warning is raised in the logs. The default is true.
• Add support for Lukso network --network=lukso
• The development option --Xfork-choice-update-head-on-block-import-enabled was changed to default to false to ensure fork-choice is run when new blocks arrive.
• The default state-cache size has been changed to 8 (previously 160), and there is now an epoch-states-cache, which defaults to a maximum of 6 elements.

Bug Fixes

• Fixed a possibility of an overflow error when calculating validator duties if the number of active validators is >1M.
