released 0.90 with a fix for compaction bug

[ChrisLu]

Just released new version 0.90: Found and fixed a bug:

If there is a delete operation during the compaction, the compaction commit step will fail.

This bug does not cause lost files, but it will cause repeated compaction retrying if there are deletions happen during the next compaction.

For large volumes, this will likely happen.

So if your use case has delete operations, use the latest version 0.90.
