0.2.2 (2013-11-04)
------------------
Note: This release does NOT change the libsigrok API. While new config keys,

acquisition on it. This helps with the collectd use-case where devices
can be removed and added dynamically while a session is running.

------------------
Note: This release does NOT change the libsigrok API.
* The 'saleae-logic' driver (which depends on the Saleae firmware), has
been replaced with the new 'fx2lafw' driver, which uses an open-source

Details: http://sigrok.org/wiki/Fx2lafw
This new driver (+ firmware) currently supports the following devices:
- ARMFLY AX-Pro
- Braintechnology USB-LPS

Only acquisition with 8 probes is supported so far. Support for 16 probes
and support for analog signal acquisition (on devices which have these
capabilities) will be added later.
* ASIX SIGMA driver:
- Add support for the ASIX SIGMA2. This requires the latest version of
the SIGMA/SIGMA2 firmware files.
Details: http://sigrok.org/wiki/Firmware
