Cleobulus is a "mandatory" upgrade version. Developers must complete the upgrade before 23:59 Singapore time on June 15, 2024 to avoid affecting node synchronization.

The main contents of the Cleobulus version include: a new proposal to adjust the energy cost of individual TVM opcodes to make the energy cost more reasonable; enhanced transaction and block checking logic to improve the system's fault tolerance; optimized inter-thread synchronization logic to improve data consistency.
