+## Redis Open Source 8.0.1 (May 2025)
+
+Update urgency: `MODERATE`: Plan an upgrade of the server, but it's not urgent.
+
+### Performance and resource utilization improvements
+
+- [#13959](https://github.com/redis/redis/pull/13959) Vector sets - faster `VSIM` `FILTER` parsing.
+
+### Bug fixes
+
+- [#QE6083](https://github.com/RediSearch/RediSearch/pull/6083) Query Engine - revert default policy `search-on-timeout` to `RETURN`.
+- [#QE6050](https://github.com/RediSearch/RediSearch/pull/6050) Query Engine - `@__key` on `FT.AGGREGATE` used as reserved field name preventing access to Redis keyspace.
+- [#QE6077](https://github.com/RediSearch/RediSearch/pull/6077) Query Engine - crash when calling `FT.CURSOR DEL` while reading from the CURSOR.
+
+### Notes
+
+- Fixed incorrect text in the license files.
