Just for completeness, I'm pasting the "Major new features" description found in the 2.2.0-rc3 release announcement: Major new features: - Per context filtering (vtid, vpid, procname) with e.g. --filter 'procname=="apache2"' - Buffers shared across applications with same user id e.g. lttng enable-channel -u mychan --buffers-uid - Implement --switch-timer and --read-timer options (periodical flush and RT-awareness). - Function entry/exit tracing (see lttng-ust-cyg-profile(3) manpage).
