   - There is generated Doxygen API documentation now.
   - The header that frontends should include is: <libsigrok/libsigrok.h>.
     There are other headers which are installed, but those are not meant to
     be included directly by the frontends.
   - There were numerous API changes, additions and removals, too many to list
     here. Please check the source code or Doxygen API documentation for the
     current set of API functions.

      that are used in some devices.
    - Add support for setting DTR/RTS.
 * gnuplot files: Add sample files for CWAV USBee DX (for 8/16 bit sampling).

   - Add a README.devices file which contains various notes for users of
     libsigrok about device- and/or driver-specific issues.
   - Update README, HACKING, and other documents.

      additional --enable-<drivername> options to selectively enable only some.
    - Improve autodetection of libraries, and only enable drivers for which
      all required libraries were found.
 * Add a test suite for libsigrok with a few unit tests (the list will grow).

0.1.1 (2012-05-30)
------------------

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
   firmware for Cypress FX2 chips which is also named 'fx2lafw'.
   Details: http://sigrok.org/wiki/Fx2lafw
   This new driver (+ firmware) currently supports the following devices:
     - ARMFLY AX-Pro
     - Braintechnology USB-LPS
     - EE Electronics ESLA100
     - EE Electronics ESLA201A
     - Robomotic MiniLogic
     - Robomotic BugLogic 3
     - Saleae Logic
     - USBee AX
     - USBee SX
     - All Cypress FX2 eval boards with stock Cypress VID/PID, including:
       - Lcsoft Mini Board
       - Braintechnology USB Interface V2.x
   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
   - Various bugfixes.
 * ZEROPLUS Logic Cube LAP-C (16032): Fix a segfault.
 * udev file: Add entries for Robomotic BugLogic 3, Velleman PCSU1000,
   Ideofy LA-08, ARMFLY AX-Pro, and Braintechnology USB Interface V2.x.
 * The zlib dependency has been removed (no longer needed).
 * Fix compiling with "Homebrew" (Mac OS X).
 * libsigrok now expects firmware files in $prefix/share/sigrok-firmware by
   default (was $prefix/share/libsigrok/firmware before).
 * Fix a Makefile.am bug which caused the generated ChangeLog files being
   accidentally deleted upon 'make distclean'.
 * ChronoVu LA8 input file format: Improve autodetection of the file format.
   We now only accept files of the size 8388613 bytes (all LA8 files have
   exactly this amount of bytes).

0.1.0 (2012-04-17)
