Release Notes v-2.0.10: Support for trim as a primary IO directive, the addition of the JSON output format for easy parsing by both humans and computers, and fixes for a Solaris compilation error, gettid on NetBSD, Windows XP/2003 compatibility, engine starvation for extraordinarily long latencies, and fallocate(), netio compatibility, and support for SIGBREAK. The critical error list is now configurable. Three new IO engines were provided: falloc, e4defrag, and Fusion-io atomic write engine. A new sample job file was provided for SSD steady state performance. A segfault race on exit on non-Linux platforms was fixed. There were various other bugfixes and improvements.
