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).

Thanks,

Mathieu
