Check if affected (2)

breakingThe redisPath field type correction
Applies if you upgrade while redisPath has an existing boolean value.
The redisPath field now uses a string for the redis-server executable directory instead of a boolean. This correction ships in Chaosd.
breakingThe fill-by-fallocate default behavior
Applies if you set fill-by-fallocate to false or omit it.
Chaosd defaults to fallocate, while Chaos Mesh uses fallocate only when fill-by-fallocate is explicitly set to true. Setting fill-by-fallocate to false or omitting it uses dd.
