Version 2.02.151 -
=================================
+ Suppress errors when snapshot merge gets delayed because volume is in use.
Avoid internal snapshot LV names in messages.
Autodetect and use /run/lock dir when available instead of /var/lock.
lvchange --refresh for merging thin origin will retry to deactivate snapshot.
