+# V4.0.1
+
+## New Features
+
+- Added a switch for the RTC function. If `Get`/`HGet` misses the cache on the RTC path, when it moves to the normal path, it directly reads from the DB without reading from the cache [#2841](https://github.com/OpenAtomFoundation/pika/pull/2841) @[cheniujh](https://github.com/cheniujh)
+
+- Optimized the Pika access cache with the RTC model to improve read performance of the Pika service [#2837](https://github.com/OpenAtomFoundation/pika/pull/2837) @[cheniujh](https://github.com/cheniujh)
+
+- Added a scheduled task for log deletion, set to delete logs every 7 days by default. This can be configured in the config file based on your needs [#2829](https://github.com/OpenAtomFoundation/pika/pull/2829) @[XiaoLiang2333](https://github.com/XiaoLiang2333)
+
+## Improvement
+
+- Added a data cleaning function to facilitate users in cleaning data during upgrades [#2888](https://github.com/OpenAtomFoundation/pika/pull/2888) @[QlQlqiqi](https://github.com/QlQlqiqi)
+
+- Changed the value in Floyd’s stored `data` field to milliseconds to be compatible with Redis commands [#2857](https://github.com/OpenAtomFoundation/pika/pull/2857) @[luky116](https://github.com/luky116)
+
+- The `flushall` command now writes `flushdb` to the binlog. If in multi-DB mode, a separate log is written for each DB to ensure correct consumption order by replica nodes [#2846](https://github.com/OpenAtomFoundation/pika/pull/2846) @[cheniujh](https://github.com/cheniujh)
+
+- Removed unnecessary logs to avoid excessive disk usage, which could impact data read/write operations [#2840](https://github.com/OpenAtomFoundation/pika/pull/2840) @[chejinge](https://github.com/chejinge)
+
+- The `incr` and `append` commands use `pksetexat` when transferring binlog to prevent incorrect operations that could cause data expiration issues, leading to dirty data [#2833](https://github.com/OpenAtomFoundation/pika/pull/2833) @[chejinge](https://github.com/chejinge)
+
+- Modified the Pika replica node binlog consumption thread model to ensure the consumption order of `binlog` [#2708](https://github.com/OpenAtomFoundation/pika/pull/2708) @[cheniujh](https://github.com/cheniujh)
+
+- Added more RocksDB metrics by introducing the `open_rocksdb_statistics_tickers` field in the configuration. By default, it's set to `no`, but turning it on will incur an additional 1.5% performance cost [#2658](https://github.com/OpenAtomFoundation/pika/pull/2658) @[baixin01](https://github.com/baixin01)
+
+## Bugfix
+
+- Fixed inaccurate cache data usage by Pika, which caused incorrect monitoring results [#2899](https://github.com/OpenAtomFoundation/pika/pull/2899) @[chejinge](https://github.com/chejinge)
+
+- Fixed the issue where an exception error signal from the `zremrangebyrank` command could cause Pika to crash [#2891](https://github.com/OpenAtomFoundation/pika/pull/2891) @[chejinge](https://github.com/chejinge)
+
+- Fixed the issue where the `Rpushx` command did not update RedisCache, leading to DB and cache inconsistency [#2879](https://github.com/OpenAtomFoundation/pika/pull/2879) @[hahahashen](https://github.com/hahahashen)
+
+- Fixed the incorrect connection termination process in the `kill client` command [#2862](https://github.com/OpenAtomFoundation/pika/pull/2862) @[cheniujh](https://github.com/cheniujh)
+
+- Fixed the issue where `blpop`/`brpop` did not update the cache when updating the DB, potentially causing inconsistency between RocksDB and RedisCache [#2858](https://github.com/OpenAtomFoundation/pika/pull/2858) @[cheniujh](https://github.com/cheniujh)
+
+- Fixed the issue where Pika did not support Redis-Sentinel [#2854](https://github.com/OpenAtomFoundation/pika/pull/2854) @[cheniujh](https://github.com/cheniujh)
+
+- Fixed inconsistent results when executing the `hincrby` command multiple times [#2836](https://github.com/OpenAtomFoundation/pika/pull/2836) @[luky116](https://github.com/luky116)
+
+- Replaced CentOS with Rocky as the default environment for GitHub CI. The process now supports MacOS/Ubuntu/Rocky [#2823](https://github.com/OpenAtomFoundation/pika/pull/2823) @[QlQlqiqi](https://github.com/QlQlqiqi)
+
+- Modified the `client watch` mechanism, where keys will become invalid if modified by anyone (including the client itself) [#2815](https://github.com/OpenAtomFoundation/pika/pull/2815) @[luky116](https://github.com/luky116)
+
+- Resolved inaccurate `slave_priority` assignment in Pika, which could cause the replica node to fail to promote to master, preventing the use of Redis-Sentinel [#2813](https://github.com/OpenAtomFoundation/pika/pull/2813) @[chejinge](https://github.com/chejinge)
+
+- Transaction commands now update both DB and RedisCache to avoid inconsistencies between the two [#2812](https://github.com/OpenAtomFoundation/pika/pull/2812) @[luky116](https://github.com/luky116)
+
+- Optimized master-slave replication to ensure that the SlaveNode on the master enters DBSync state before submitting the `bgsave` task, preventing binlog deletion during extreme cases while `bgsave` is being executed [#2798](https://github.com/OpenAtomFoundation/pika/pull/2798) @[cheniujh](https://github.com/cheniujh)
+
+- Modified the binlog handling logic during master-slave replication to ensure sequential execution and prevent inconsistencies between master and replica [#2794](https://github.com/OpenAtomFoundation/pika/pull/2794) @[cheniujh](https://github.com/cheniujh)
+
+- Fixed inaccurate BlockCache calculations [#2797](https://github.com/OpenAtomFoundation/pika/pull/2797) @[bigdaronlee163](https://github.com/bigdaronlee163)
+
+- Added flag bits, timestamps, and return value mechanisms to ensure Pika correctly handles conflicts when executing `flushdb` while processing asynchronous deletion of old directories [#2790](https://github.com/OpenAtomFoundation/pika/pull/2790) @[cheniujh](https://github.com/cheniujh)
+
+- Fixed the issue where inconsistent data amounts between master and replica during Redis-Sentinel failover could cause the state transition to error [#2766](https://github.com/OpenAtomFoundation/pika/pull/2766) @[cheniujh](https://github.com/cheniujh)
+
+- Fixed the issue where multiple replica instance expansions could cause full replication to fail [#2756](https://github.com/OpenAtomFoundation/pika/pull/2756) @[cheniujh](https://github.com/cheniujh)
