0.3.0 (2014-05-06)
------------------
Note: This release DOES change the libsigrokdecode public C API. This
means it is NOT backwards-compatible and frontends will need updates.
* New supported protocol decoders:
- guess_bitrate Guess the bitrate/baudrate of a signal
- ir_nec NEC infrared remote control protocol
- ir_rc5 RC-5 infrared remote control protocol
- midi Musical Instrument Digital Interface
- parallel Parallel synchronous bus decoder
- rgb_led_spi RGB LED string decoder (SPI)
- xfp 10 Gigabit Small Form Factor Pluggable Module
- z80 Zilog Z80 microprocessor disassembly
* Add support for annotation rows, i.e. groups of annotation classes that
are supposed to be displayed on the same GUI "row" together.
* Add support for the new OUTPUT_BINARY feature, which allows PDs to output
decoded data in various file formats (for loading and further processing
in other tools, or for direct live piping into other tools).
* Add support for the OUTPUT_META output type. This is used by PDs for
reporting various data points to the frontends, allowing them to perform
various post-processing and statistics tasks on them (e.g. simple counts,
average/mean values, min/max values, and so on).
* The OUTPUT_PROTO output type is now called OUTPUT_PYTHON.
* All protocol decoders:
- Bump the 'api_version' field of all decoders to 2. They are no longer
compatible (and cannot be used with) older libsigrokdecode versions.
- Updates to emit proper annotation classes, annotation sample numbers,
and annotation rows for GUI usage (bugs #146, #148, #150, #151, #154,
#155, #162, #147, #163, #168, #156, #309, and #344).
- Longer and shorter annotations are now supplied for GUI usage (frontends
can for example always show the longest annotation per zoom-level).
- Extensive protocol information has been moved from the PDs to the wiki.
Example: http://sigrok.org/wiki/Protocol_decoder:Uart
- Use correct I²C / I²S names in user-visible texts (not I2C/I2S).
* dcf77:
- Fix a bug in the handling of DCF77 bit 0.
- Drop handling of the 'PON' pin, this is not DCF77 related (bug #153).
- Fix the data parity check (bug #157).
* i2c:
- Fix corner case that can yield issues when using triggers on LAs.
- Drop unneeded 'addressing' option.
- Output bit-exact annotations and data for use by stacked PDs.
* i2s:
- Add OUTPUT_BINARY support for dumping the decoded data in WAV format.
* lpc:
- Various fixes to make the PD work better (or at all).
- Fix the handling of optional channels.
- Make the RESET# pin optional.
* onewire_link:
- Split 'reset' and 'presence' annotations.
* pan1321:
- Support the JSEC, JPRO, JAAC, and JSDA commands.
- Various internal fixes and improvements.
* parallel:
- Fix internal use of the obsolete 'metadata' parameter (bug #202).
* rtc8564:
- Properly handle register 0x06 (weekday) and the 'century' bit.
* sdcard_spi:
- Emit bit-exact annotations for the register fields that need them.
- Fix a Python issue with duplicate keys in a dict (bug #191).
* spi:
- Either MISO or MOSI can be optional now, but not both (bug #175).
- The CS# pin is optional now. If the pin is supplied, it is honored
(decoding only happens when the pin is asserted). Otherwise decoding will
use every CLK edge, regardless of CS# state or CS# existence (bug #152).
- Rename the 'SCK' pin to the more common 'CLK'.
- Output bit-exact annotations and data for use by stacked PDs.
- Fix a bug occurring when only MOSI (but not MISO) was supplied.
* transitioncounter:
- Drop the obsolete 'transitioncounter' dummy protocol decoder.
* uart:
- Fix corner case that can yield issues when using triggers on LAs.
- Use 'T' for stop bits and 'P' for parity bits (shortest annotations).
- Add a data format selection option.
- Annotations for RX and TX are now emitted in different annotation rows.
- Either the RX or TX signal can be optional now (but not both).
- Fix incorrectly displayed characters (bug #201).
- Add support for OUTPUT_BINARY output for RX, TX, or both.
- Output bit-exact annotations and data for use by stacked PDs.
* uart_dump:
- Drop the obsolete 'uart_dump' decoder (the feature is now included
in the 'uart' protocol decoder itself via OUTPUT_BINARY).
* usb_packet:
- The 'usb_protocol' decoder has been renamed to 'usb_packet'.
- Various bugfixes and decoding improvements.
* usb_signalling:
- Fix decoding of individual bits, sample in the middle of bits (bug #158).
* libsigrokdecode API changes overview:
- Add srd_session_new(), srd_session_destroy(), and a session context.
- Add srd_session_metadata_set().
- The name 'probe' has been renamed to 'channel' everywhere.
- The lib no longer defineѕ names with _t suffix (POSIX reserved).
- Drop the obsolete SRD_MAX_NUM_PROBES.
- Add the SRD_CONF_SAMPLERATE config key.
- Please see the Doxygen API documentation for further details.
* Protocol decoder API:
- Metadata is passed to PDs at runtime now (not at decoder start).
PDs now have a new optional metadata() method to receive it.
- Output types are now registered via Decoder.register(), not Decoder.add().
- The report() method is now obsolete. This kind of information will be
passed to the frontends via the OUTPUT_META output type, allowing the
frontends to perform various post-processing and statistics tasks.
- PDs can now define BINARY_OUTPUT types via the 'binary' tuple.
- PDs can now define annotation rows via the 'annotation_rows' tuple.
- PD options are now a tuple of dicts. Each option is a dict containing
the keys 'id', 'desc', 'def', and 'values'. Valid option types are
UTF-8 strings, integers, and floats (bugs #254, #306, #317, #165).
- Channels, optional channels, and annotations are now tuples (not lists).
- Only load PDs of API version 2, all other versions are incompatible.
* srd_inst_channel_set_all(): Report an error if not all channels required
by the respective protocol decoder have been supplied.
* Remove some internal limitations to max. 64 channels (bug #120).
* Add a unit test suite framework for libsigrokdecode ('make check').
* Add a protocol decoder test-suite framework for developers (tests/pdtest).
* Various bugfixes:
- srd_inst_option_set(): Properly return an error on exceptions.
- srd_inst_option_set(): Fix setting of instance options, caused by class
variable clobbering or releasing borrowed references (bugs #170, #174).
- srd_decoder_load(): Error out upon invalid module names (bug #176).
- srd_decoder_load(): Don't try to load an already loaded PD twice.
- srd_decoder_load_all(): Avoid issues without prior srd_init() (bug #178).
- srd_decoder_doc_get(): Fix an issue in the unit test suite (bug #179).
- srd_pd_output_callback_add(): Honor cb_data value (bug #143).
- Fix issues with PDs not getting the samplerate (bugs #97, #132, #166).
- Don't incorrectly decrease a borrowed reference (bug #177).
- Fix various memory leaks and segfault conditions.
* Build system:
- Use pkg-config (not python3-config) to check for Python libs.
This enables (better) libsigrokdecode cross-compile support.
- PDs no longer have an extra Makefile.am, and 'make install' now
happens via a Python script.
- configure: Clearly mark required and optional libs.
- Fix an issue with DESTDIR support (bug #215).
- Add the HACKING file to the tarball.
* Updated or new build-time and runtime requirements:
- Python >= 3.2 (required)
- check >= 0.9.4 (optional, only needed for the libsigrokdecode testsuite)
- libsigrok >= 0.3.0 (optional, only needed for the developer PD testsuite)
- python3-coverage (optional, only needed for the developer PD testsuite)
* New 'make install'-time requirement:
- Python >= 3.2 (required)
0.2.0 (2013-05-04)
------------------
Note: This release DOES change the libsigrokdecode public C API. This
means it is NOT backwards-compatible and frontends will need updates.
* New supported protocol decoders:
- Dallas DS1307 RTC
* Library: Decoders now expose their options via the GSList *options field
in struct srd_decoder.
* API related changes:
- Various API documentation fixes.
- srd_decoder_list() now returns 'const GSList *' instead of 'GSList *'.
- Added new srd_strerror() and srd_strerror_name() API calls.
* Added support for optional probes for PDs.
0.1.1 (2013-01-27)
------------------
Note: This release does NOT change the libsigrokdecode public C API. This
means existing libsigrokdecode frontends should not require any changes.
However, individual PDs and their output changed, which may require
some adaptations on the user's side in some cases.
* New supported protocol decoders:
- avr_isp AVR In-System Programming
- can Controller Area Network
- jtag Joint Test Action Group (IEEE 1149.1)
- jtag_stm32 Joint Test Action Group / ST STM32
- lm75 National LM75
- lpc Low-Pin-Count
- maxim_ds28ea00 Maxim DS28EA00 1-Wire digital thermometer
- onewire_link 1-Wire serial communication bus (link layer)
- onewire_network 1-Wire serial communication bus (network layer)
- sdcard_spi Secure Digital card (SPI mode)
- tlc5620 Texas Instruments TLC5620
- uart_dump UART dump
* i2cfilter: Now outputs 'i2c' packets instead of just data bytes, so
other PDs can stack on top of it. It filters by I2C slave address.
* edid: Now takes 'i2c' packets as input.
* pan1321:
- Various bugfixes to make the PD actually work.
- Now features 'Text (short)' and 'Text (verbose)' outputs.
* usb:
- The PD is split into 'usb_signalling' and 'usb_protocol' (stacked on top).
- Various bugfixes to make the PD work (better).
- The DP/DM probes were swapped, this is now fixed.
- Preliminary support for USB low-speed (in addition to full-speed).
* mlx90614: Minor bugfixes.
* dcf77:
- Major bugfix, this PD was not working correctly at all.
- Handle PON signal.
* nunchuk: Complete rewrite, works (better) now.
* spi: Update docs, send CS# change packets, change output API slightly.
If you have a PD which stacks on top of SPI, it'll need to be adapted.
The PDs that ship with libsigrokdecode are updated already.
* mx25lxx05d:
- Implement support for the READ, RDSR, and PP commands.
- Decode status register bits.
- Fix SE command handling.
- Fix inverted SRWD bit handling.
* Various smaller style and consistency changes in code and PD descriptions.

* Performance improvements in some PDs.
* Documentation: Update website and git URLs.
* pkg-config file: Small fix to improve behaviour on Windows with cmake.
* All PD implementation files are now named 'pd.py' consistently.
* configure script:
- Also check for python3.3-config in addition to python-config and others.
- Add missing -fvisibility=hidden to default CFLAGS.
- Fix CFLAGS handling (configure.ac amends CFLAGS, doesn't overwrite now).
* The minimum required glib version is 2.24.0 now.
* We now ship a standard INSTALL file which documents the 'configure' options.
0.1.0 (2012-04-17)
