--long-query-time is now given in seconds with microseconds as decimals --min_examined_row_limit added for slow query log long_query_time user variable is now double with 6 decimals Added functions to get time in microseconds Added faster time() functions for system that has gethrtime() (Solaris) We now do less time() calls. Added field->in_read_set() and field->in_write_set() for easier field manipulation by handlers set_var.cc and my_getopt() can now handle DOUBLE variables. All time() calls changed to my_time() my_time() now does retry's if time() call fails. Added debug function for stopping in mysql_admin_table() when tables are locked Some trivial function and struct variable renames to avoid merge errors. Fixed compiler warnings Initialization of some time variables on windows moved to my_init()
