 ### Breaking Changes
 
-- The response of the Attestation Rewards method was updated to include two extra
-  fields (`inactivity` and `inclusion_delay`) into the `total_rewards` and `ideal_rewards` objects.
-  This should be considered a breaking change only if you are strictly
-  checking the structure of the json in the response.
-
 ### Additions and Improvements
 
-- Solve an unintended breaking change in `23.9.1` release which was including an updated leveldb
-  native library not compatible with relative old Linux distributions. Leveldb native library has
-  been updated to support older GLIBC versions (ie Ubuntu 20.04 and Debian 11).
-
 ### Bug Fixes
-- During network configuration load, all missing fields will now be reported, rather than just the first missing field causing failure.
