In CHANGELOG.MD around line 60, the entry references PR #3113 but the link
targets /pull/3107; update the URL to match the referenced PR by changing the
link to /pull/3113 (i.e. replace
"https://github.com/OpenAtomFoundation/pikiwidb/pull/3107" with
"https://github.com/OpenAtomFoundation/pikiwidb/pull/3113") so the displayed PR
number and URL are consistent.

- Added the `log-net-activities` parameter in the configuration file to dynamically enable or disable the logging of certain connection-related activities. This can be adjusted with `config get/set`. [#2964](https://github.com/OpenAtomFoundation/pika/pull/2964) @[cheniujh](https://github.com/cheniujh)

- RedisCache now avoids storing large keys to prevent excessive memory usage or the eviction of frequently accessed hot keys, which could impact performance. [#2557](https://github.com/OpenAtomFoundation/pika/pull/2557) @[QlQlqiqi](https://github.com/QlQlqiqi)

- Solved the problem of consistency between Pika database and cache [#3034](https://github.com/OpenAtomFoundation/pikiwidb/pull/3034) [#3037](https://github.com/OpenAtomFoundation/pikiwidb/pull/3037) @[Mixficsol](https://github.com/Mixficsol)
