Bump version to 0.10.9.3
Perform minor version bump to rectify PVP violation

The patch-level bump in 60cbe2c6ec2796da4d187caf018ed24d697f1f09 didn't suffice
to conform to the PVP, as in 3cbb0ec457358bc55ee0a2408bb60d45f4f01acf a new instance
was defined, therefore at least a minor version bump would have been needed.

By uploading a 0.10.10.0 release, and declaring the 0.10.9.3 release a "non-preferred"
release, everything should be fine again.
