| 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 |

| - 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). |

| * i2c: |
| - Fix corner case that can yield issues when using triggers on LAs. |
| - Drop unneeded 'addressing' option. |

| - 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. |

| - 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. |

| - 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: |

| |
| 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: |

| |
| 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. |
