916 - Various bugfixes when setting time/sample limits.
917 * openbench-logic-sniffer driver:
918 - Don't try to scan all available serial ports for OLS devices. Instead,
919 the serial port to use now has to be specified by the user.
920 - Allow disabling RLE.
921 * udev rules file: Add many new entries for additional devices.
922 * New output formats:
923 - analog: Prints analog values and their unit (e.g. from scopes or DMMs).
924 * New input formats:
925 - vcd: Value Change Dump format
926 - wav: Waveform audio file format (for analog data)
927 * 'binary' input format: Add support for a 'samplerate' option.
928 * API related changes:
929 - There is generated Doxygen API documentation now.
930 - The header that frontends should include is: <libsigrok/libsigrok.h>.
931 There are other headers which are installed, but those are not meant to
932 be included directly by the frontends.
933 - There were numerous API changes, additions and removals, too many to list
934 here. Please check the source code or Doxygen API documentation for the
935 current set of API functions.
936 * Serial port code:
937 - Various improvements and fixes related to multiple parameters such as
938 directions, baudrate, flow control, and others.
939 - Add support for more baudrates (e.g. very low ones such as 600/1200)
940 that are used in some devices.
941 - Add support for setting DTR/RTS.
942 * gnuplot files: Add sample files for CWAV USBee DX (for 8/16 bit sampling).
943 * Documentation updates:
944 - Add a README.devices file which contains various notes for users of
945 libsigrok about device- and/or driver-specific issues.
946 - Update README, HACKING, and other documents.
947 - Updated build dependencies list.
948 - The following libs are needed in more recent versions now:
949 - glib (required): Now must be >= 2.32.0.
950 - libusb-1.0 (optional): Now must be >= 1.0.9.
951 - The following new libs were added as (optional) dependencies:
952 - libasound / alsa-lib (optional): >= 1.0
953 - check (optional, only needed for unit tests): >= 0.9.4
954 * Portability:
955 - Various compile fixes for Windows, FreeBSD/NetBSD/OpenBSD, and Mac OS X.
956 - Simplify/allow/fix cross-compilation of libsigrok.
957 - Various bugfixes for 32bit systems.
958 - Various endianness fixes.
959 * configure:
960 - Add a --disable-all-drivers option. This can be overridden by
961 additional --enable-<drivername> options to selectively enable only some.
962 - Improve autodetection of libraries, and only enable drivers for which
963 all required libraries were found.
964 * Add a test suite for libsigrok with a few unit tests (the list will grow).
966 0.1.1 (2012-05-30)
967 ------------------
969 Note: This release does NOT change the libsigrok API.
971 * The 'saleae-logic' driver (which depends on the Saleae firmware), has
972 been replaced with the new 'fx2lafw' driver, which uses an open-source
973 firmware for Cypress FX2 chips which is also named 'fx2lafw'.
974 Details: http://sigrok.org/wiki/Fx2lafw
975 This new driver (+ firmware) currently supports the following devices:
976 - ARMFLY AX-Pro
977 - Braintechnology USB-LPS
978 - EE Electronics ESLA100
979 - EE Electronics ESLA201A
980 - Robomotic MiniLogic
981 - Robomotic BugLogic 3
982 - Saleae Logic
983 - USBee AX
984 - USBee SX
985 - All Cypress FX2 eval boards with stock Cypress VID/PID, including:
986 - Lcsoft Mini Board
987 - Braintechnology USB Interface V2.x
988 Only acquisition with 8 probes is supported so far. Support for 16 probes
989 and support for analog signal acquisition (on devices which have these
990 capabilities) will be added later.
991 * ASIX SIGMA driver:
992 - Add support for the ASIX SIGMA2. This requires the latest version of
993 the SIGMA/SIGMA2 firmware files.
994 Details: http://sigrok.org/wiki/Firmware
995 - Various bugfixes.
996 * ZEROPLUS Logic Cube LAP-C (16032): Fix a segfault.
997 * udev file: Add entries for Robomotic BugLogic 3, Velleman PCSU1000,
998 Ideofy LA-08, ARMFLY AX-Pro, and Braintechnology USB Interface V2.x.
999 * The zlib dependency has been removed (no longer needed).
1000 * Fix compiling with "Homebrew" (Mac OS X).
1001 * libsigrok now expects firmware files in $prefix/share/sigrok-firmware by
1002 default (was $prefix/share/libsigrok/firmware before).
1003 * Fix a Makefile.am bug which caused the generated ChangeLog files being
1004 accidentally deleted upon 'make distclean'.
1005 * ChronoVu LA8 input file format: Improve autodetection of the file format.
1006 We now only accept files of the size 8388613 bytes (all LA8 files have
1007 exactly this amount of bytes).
1009 0.1.0 (2012-04-17)
1010 ------------------
1012 * Initial release.
