(https://github.com/RediSearch/RediSearch/pull/7076,
https://github.com/RediSearch/RediSearch/pull/6857) - Introducing
`FT.HYBRID`, a new command that enables hybrid queries combining both
text and vector search, with support for **RRF** and **LINEAR** result
combination. This update enhances performance and reliability through a
more efficient networking layer, smoother query execution, and improved
overall stability.
(https://github.com/RediSearch/RediSearch/pull/7065) - Add
`search-default-scorer` configuration to set the default text scorer
across queries (by default it is BM25).
https://github.com/RediSearch/RediSearch/pull/7022 - Handle Atomic Slot
Migration events upon moving slots from one node to another in a cluster
mode.

https://github.com/RediSearch/RediSearch/pull/6828,
https://github.com/RediSearch/RediSearch/pull/6877,
https://github.com/RediSearch/RediSearch/pull/6921) - Introduce query
time memory guardrails by adding a new `search-on-oom` configuration
which defines the query engine behavior when OOM (Out Of Memory) is
reached. OOM checks are applied to `FT.SEARCH`, `FT.AGGREGATE`, and
`FT.HYBRID` commands. The behavior on OOM can be configured to one of
three modes: `IGNORE`, `FAIL`, or `RETURN`.
`IGNORE` - The default behavior, run queries anyway (not recommended for
heavy queries returning a large result set).
`FAIL` - Fail query execution immediately if any of the nodes are in OOM
state when query execution starts.
`RETURN` - A best effort appraoch to return partial results when OOM is
detected in only some of the nodes in a cluster mode.
A new BUILD_WITH_MODULES flag was added to the Makefile to control
building the module directory.
The new module directory includes a general Makefile that iterates
over each module, fetch a specific version, and build it.
