Few questions about new version 3.3.2

[Snake]

Hello Michal, loving the new version, server load is much lower and things working much faster, very pleased.

Just want to know if the new changes make the database work different?

Since new version is there old data that can be removed from database as it is no longer used?

Thanks.

Cache is used as it was. So you do not need to remove anything from there.
