The benefits of the upgrade are numerous. First, the maximum number of characters in the title has increased from 40 Chinese characters to 256 characters, which means we can have more keywords and be more easily searchable. Additionally, the upgraded system supports UTF8 encoding, allowing for full support of all characters in languages like Japanese, Korean, French, Russian, and more. Previously, there were issues with supporting the languages and names of international friends, but now it is fully supported. Overall, this upgrade is very powerful!
