The starting mark usually occurs when the developers announce the new version upgrade, explaining the specific content of the upgrade and its corresponding version number. The ending mark occurs when the upgrade is completed, and the blockchain  system is running normally, with new features and optimizations being actually applied. During the upgrade process, there may be some testing phases and transition periods to ensure the stability and compatibility of the new version. These phases also serve as markers in the entire process of version upgrading. In summary, the beginning and ending signs of a blockchain version upgrade mainly occur during the announcement of the new version, testing, and the actual application stage."}]}],"pr":"11823d2bc736995b57057d1cda747a6bfcedabe4082a6ae5dba1db23382276f0"}
