4 Note: This release does NOT change the libsigrok API. While new config keys,
5 config info types, and unit codes have been added (additional enum
6 entries / numbers), no existing interfaces were added/changed/removed.
7 Frontends should continue to work fine without recompiling or relinking.
9 * New supported hardware:
24 - SR_CONF_VOLTAGE_THRESHOLD
25 - SR_CONF_EXTERNAL_CLOCK
28 * New config info types:
31 - SR_UNIT_REVOLUTIONS_PER_MINUTE
36 - csv (comma-separated values)
37 * Bump required libzip version to >= 0.10.
38 * uni-t-dmm: This driver now requires the specification of the USB VID/PID
39 of the cable that is used. Example for sigrok-cli:
40 - Old: sigrok-cli --driver voltcraft-vc820 ...
41 - New: sigrok-cli --driver voltcraft-vc820:conn=1a86.e008 ...
42 * openbench-logic-sniffer:
43 - Initial test pattern support (SR_CONF_PATTERN_MODE).
44 - Initial external clock support (SR_CONF_EXTERNAL_CLOCK).
45 - Initial channel swap support (SR_CONF_SWAP).
46 - Various minor fixes and improvements.
47 * When a frontend adds a device instance to a running session, start
48 acquisition on it. This helps with the collectd use-case where devices
49 can be removed and added dynamically while a session is running.
50 * rigol-ds1xx2: Support newer Linux kernels with USBTMC in /sys/class/usbmisc.
51 * rigol-ds1xx2: Also detect the Rigol DS1152E/DS1152D.

59 * Add the missing HACKING file to the tarball.
60 * README.devices: Updates/notes for newly added devices.
65 Note: This release does NOT change the libsigrok API. While new config keys,
66 config info types, and error codes have been added (additional enum
67 entries / numbers), no existing interfaces were added/changed/removed.
68 Frontends should continue to work fine without recompiling or relinking.
70 * New supported hardware:

109 Note: This release DOES change the libsigrok API. That means it is NOT
110 backwards-compatible and frontends will need updates.
112 * Support for analog sources (oscilloscopes, DMMs, data loggers) was added.
113 * New supported hardware:
116 - ZEROPLUS LAP-16128U

160 * The limitation of max. 64 digital probes has been removed in many places.
161 * Added generic DMM protocol parsers usable for various DMMs, over various
162 cables and/or transports (e.g. same protocol over serial or USB/HID):
163 - Cyrustek ES51922 binary protocol.
164 - Fortune Semiconductor FS9721_LP3/FS9721B binary protocol.
165 - Fortune Semiconductor FS9922-DMM3/DMM4 binary protocol.

178 - Fix multi-stage (software) triggers.
179 - Fix various memory leaks, firmware upload timeout bugs, and other issues.
180 - Various performance and memory usage improvements in the driver.

184 - Various bugfixes when setting time/sample limits.
185 * openbench-logic-sniffer driver:
186 - Don't try to scan all available serial ports for OLS devices. Instead,
187 the serial port to use now has to be specified by the user.

199 There are other headers which are installed, but those are not meant to
200 be included directly by the frontends.
201 - There were numerous API changes, additions and removals, too many to list
202 here. Please check the source code or Doxygen API documentation for the
203 current set of API functions.
205 - Various improvements and fixes related to multiple parameters such as
206 directions, baudrate, flow control, and others.
207 - Add support for more baudrates (e.g. very low ones such as 600/1200)
208 that are used in some devices.
209 - Add support for setting DTR/RTS.
210 * gnuplot files: Add sample files for CWAV USBee DX (for 8/16 bit sampling).

228 - Add a --disable-all-drivers option. This can be overridden by
229 additional --enable-<drivername> options to selectively enable only some.
230 - Improve autodetection of libraries, and only enable drivers for which
231 all required libraries were found.
232 * Add a test suite for libsigrok with a few unit tests (the list will grow).
237 Note: This release does NOT change the libsigrok API.
239 * The 'saleae-logic' driver (which depends on the Saleae firmware), has
240 been replaced with the new 'fx2lafw' driver, which uses an open-source
241 firmware for Cypress FX2 chips which is also named 'fx2lafw'.
242 Details: http://sigrok.org/wiki/Fx2lafw
243 This new driver (+ firmware) currently supports the following devices:
245 - Braintechnology USB-LPS
246 - EE Electronics ESLA100
247 - EE Electronics ESLA201A
248 - Robomotic MiniLogic
249 - Robomotic BugLogic 3
253 - All Cypress FX2 eval boards with stock Cypress VID/PID, including:
255 - Braintechnology USB Interface V2.x
256 Only acquisition with 8 probes is supported so far. Support for 16 probes
257 and support for analog signal acquisition (on devices which have these
258 capabilities) will be added later.
260 - Add support for the ASIX SIGMA2. This requires the latest version of
261 the SIGMA/SIGMA2 firmware files.
262 Details: http://sigrok.org/wiki/Firmware
264 * ZEROPLUS Logic Cube LAP-C (16032): Fix a segfault.
265 * udev file: Add entries for Robomotic BugLogic 3, Velleman PCSU1000,
266 Ideofy LA-08, ARMFLY AX-Pro, and Braintechnology USB Interface V2.x.
267 * The zlib dependency has been removed (no longer needed).
268 * Fix compiling with "Homebrew" (Mac OS X).
269 * libsigrok now expects firmware files in $prefix/share/sigrok-firmware by
270 default (was $prefix/share/libsigrok/firmware before).
271 * Fix a Makefile.am bug which caused the generated ChangeLog files being
272 accidentally deleted upon 'make distclean'.
273 * ChronoVu LA8 input file format: Improve autodetection of the file format.
274 We now only accept files of the size 8388613 bytes (all LA8 files have
275 exactly this amount of bytes).
