### New Features in binary distributions

- 7 new data structures: JSON, Time series, Bloom filter, Cuckoo filter,
Count-min sketch, Top-k, t-digest
- Redis scalable query engine (including vector search)

### Potentially breaking changes

- #12272 `GETRANGE` returns an empty bulk when the negative end index is
out of range
- #12395 Optimize `SCAN` command when matching data type

### Bug fixes

- #13510 Fix `RM_RdbLoad` to enable AOF after RDB loading is completed
- #13489 `ACL CAT` - return module commands
- #13476 Fix a race condition in the `cache_memory` of `functionsLibCtx`
- #13473 Fix incorrect lag due to trimming stream via `XTRIM` command
- #13338 Fix incorrect lag field in `XINFO` when tombstone is after the
`last_id` of the consume group
- #13470 On `HDEL` of last field - update the global hash field
expiration data structure
- #13465 Cluster: Pass extensions to node if extension processing is
handled by it
- #13443 Cluster: Ensure validity of myself when loading cluster config
- #13422 Cluster: Fix `CLUSTER SHARDS` command returns empty array

### Modules API

- #13509 New API calls: `RM_DefragAllocRaw`, `RM_DefragFreeRaw`, and
`RM_RegisterDefragCallbacks` - defrag API to allocate and free raw
memory

### Performance and resource utilization improvements

- #13503 Avoid overhead of comparison function pointer calls in listpack
`lpFind`
- #13505 Optimize `STRING` datatype write commands
- #13499 Optimize `SMEMBERS` command
- #13494 Optimize `GEO*` commands reply
- #13490 Optimize `HELLO` command
- #13488 Optimize client query buffer
- #12395 Optimize `SCAN` command when matching data type
- #13529 Optimize `LREM`, `LPOS`, `LINSERT`, and `LINDEX` commands
- #13516 Optimize `LRANGE` and other commands that perform several
writes to client buffers per call
- #13431 Avoid `used_memory` contention when updating from multiple
threads

### Other general improvements

- #13495 Reply `-LOADING` on replica while flushing the db

### CLI tools

- #13411 redis-cli: Fix wrong `dbnum` showed after the client
reconnected

### Notes

- No backward compatibility for replication or persistence.
- Additional distributions, upgrade paths, features, and improvements
will be introduced in upcoming pre-releases.
- With the GA release of 8.0 we will deprecate Redis Stack.

This is a missing of the PR #13383.
We will call `functionsLibCtxClear()` in bio, so we shouldn't touch
`curr_functions_lib_ctx` in it.
