### Highlights

RedisJSON 2.4 contains several low-level API changes in order to support the multi-value indexing and querying support that comes with RediSearch 2.6. RediSearch 2.6 comes with multi-value indexing and querying of attributes for any attribute type (Text, Tag, Numeric, Geo and Vector) defined by a JSONPath leading to an array or to multiple scalar values.

### What's new in 2.4

- Features:

  - [#848](https://github.com/RedisJSON/RedisJSON/pull/848) Add JSONPath filter the regexp match operator (MOD-4432)
  - [#861](https://github.com/RedisJSON/RedisJSON/pull/861) Support legacy JSONPath with the dollar sign $ (MOD-4436)

- Performance enhancements:

  - [#699](https://github.com/RedisJSON/RedisJSON/pull/699) A new JSONPath library which enhances the performance of parsing any JSONPath expression in RedisJSON.

- Changing behaviour:

  - [#699](https://github.com/RedisJSON/RedisJSON/pull/699) Floating point numbers which become round numbers due to some operation, such as `JSON.NUMINCRBY`, will now return as a floating point with a trailing `.0`, e.g., instead of just `42`, now `42.0` will be returned.

- Bugs fixes (since 2.4-RC1/ v2.4.0):

  - [#850](https://github.com/RedisJSON/RedisJSON/pull/850) Allow repetition of filter relation instead of optional (MOD-4431)
