2.5.0

Important Notice

Dependency Updates: RocksDB is bumped from 8.1.1 to 8.3.2 in this version.

Highlights: We have supported Redis-compatible SCAN cursors so that you can use any Redis client library to perform the SCAN far painless than before. Enable it via redis-cursor-compatible in the configuration file. Many thanks to @jihuayu. Meanwhile, lots of ZSET commands are newly supported, like ZMPOP, ZRANGESTORE, BZMPOP, ZUNION. Many thanks to @infdahai for driving them and other contributors for implementing them. The detailed changes and contributors are listed below.
