2.3.0

Version 2.3.0 of the Chia reference client is now available for download! This release includes a soft fork, which will activate at the end of July 2024. It also includes a security fix. Everyone should upgrade their farmers and harvesters to at least version 2.3.0 as soon as time permits.

This release includes the Chialisp message conditions from CHIP-25, the wallet sync protocol from CHIP-26, various DataLayer performance improvements, and a few other ease-of-use updates.
