Version 1.02.85 -
===================================
When buffer for dm_get_library_version() is too small, return error code.
Always reinitialize _name_mangling_mode in dm_lib_init().
Add tracking flag about implicitly added devices into dm_tree.
Stop timeout thread immediately when the last worker thread is finished.
