14430.1.1 (2012-05-30)
1444------------------
1445
1446Note: This release does NOT change the libsigrok API.
1447
1448 * The 'saleae-logic' driver (which depends on the Saleae firmware), has
1449   been replaced with the new 'fx2lafw' driver, which uses an open-source
1450   firmware for Cypress FX2 chips which is also named 'fx2lafw'.
1451   Details: http://sigrok.org/wiki/Fx2lafw
1452   This new driver (+ firmware) currently supports the following devices:
1453     - ARMFLY AX-Pro
1454     - Braintechnology USB-LPS
1455     - EE Electronics ESLA100
1456     - EE Electronics ESLA201A
1457     - Robomotic MiniLogic
1458     - Robomotic BugLogic 3
1459     - Saleae Logic
1460     - USBee AX
1461     - USBee SX
1462     - All Cypress FX2 eval boards with stock Cypress VID/PID, including:
1463       - Lcsoft Mini Board
1464       - Braintechnology USB Interface V2.x
1465   Only acquisition with 8 probes is supported so far. Support for 16 probes
1466   and support for analog signal acquisition (on devices which have these
1467   capabilities) will be added later.
1468 * ASIX SIGMA driver:
1469   - Add support for the ASIX SIGMA2. This requires the latest version of
1470     the SIGMA/SIGMA2 firmware files.
1471     Details: http://sigrok.org/wiki/Firmware
1472   - Various bugfixes.
1473 * ZEROPLUS Logic Cube LAP-C (16032): Fix a segfault.
1474 * udev file: Add entries for Robomotic BugLogic 3, Velleman PCSU1000,
1475   Ideofy LA-08, ARMFLY AX-Pro, and Braintechnology USB Interface V2.x.
1476 * The zlib dependency has been removed (no longer needed).
1477 * Fix compiling with "Homebrew" (Mac OS X).
1478 * libsigrok now expects firmware files in $prefix/share/sigrok-firmware by
1479   default (was $prefix/share/libsigrok/firmware before).
1480 * Fix a Makefile.am bug which caused the generated ChangeLog files being
1481   accidentally deleted upon 'make distclean'.
1482 * ChronoVu LA8 input file format: Improve autodetection of the file format.
1483   We now only accept files of the size 8388613 bytes (all LA8 files have
1484   exactly this amount of bytes).
1485
