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# existance (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 occuring 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.
