Looks like v2.0.10 was a bit troublesome release. I expect this one to last longer.

* dotlock_use_excl setting's default was accidentally "no" in all
  v2.0.x releases, instead of "yes" as in v1.1 and v1.2. Changed it
  back to "yes".

- v2.0.10: LDAP support was broken
- v2.0.10: dsyncing to remote often hanged (timed out in 15 mins)
