Honestly speaking, I hardly remember what was in 0.1.0 version.
You may have noticed former releases are marked as deprecated and only
0.7.0 and 0.8.0 versions are available from the list of current
downloads (

Many of us are doing stress tests and I'm not aware of any race
condition related issue in server since 0.7.0
