This file contains information about the changes done to ODR-DabMux in this repository 2020-05-26: Matthias P. Braendli (v3.1.1): Fix FIG2 segment count issue. Handle disconnects better in EDI output. Fix buffering issue with timestamped EDI input. 2020-04-15: Matthias P. Braendli (v3.1.0): Initialise TIST on startup rounded to 24ms, as it was done before v2.4.0 (see '5b1dea7'). Refresh TAI bulletin before it expires. Set SO_REUSEADDR for TCP listening sockets (avoids some startup failures). Add EDI input TIST delay setting, and improve EDI input stats and error handling. Add FIG 0/7 and Alarm announcement support (Thanks to Mathias Kuntze). Add startupcheck functionality to ODR-DabMux and ODR-ZMQ2EDI. ZMQ2EDI will not quit anymore in case of input issues. Handle FCT discontinuity in ZMQ2EDI, and display better statistics which are usable by the new munin stats script doc/stats_zmq2edi_munin.py. 2019-10-30: Matthias P. Braendli (v3.0.1): Fix compilation on older systems (like debian jessie) 2019-10-29: Matthias P. Braendli (v3.0.0): Add EDI input with support for timestamps, which requires a change in the configuration file format for the input specification. This marks the beginning of a transition away from the ZMQ contribution protocol towards the standard EDI, including EDI-over-TCP. Move code shared with other mmbTools into a separate `common` repository. Change default TAI clock cache storage location to `/var/tmp/odr-leap-seconds.cache`. Add encoder version and uptime to stats if available (carried over EDI, not ZMQ). Fix nonblocking file input. Modify ODR-zmq2edi and ODR-zmq2farsync timeout behaviour. 2019-12-20: Matthias P. Braendli (v2.4.2): Backport the file input nonblock fix to v2.4.1. 2019-06-25: Matthias P. Braendli (v2.4.1): Fix bug when odr-zmq2edi is used with more than one destination. 2019-06-07: Matthias P. Braendli (v2.4.0): Add timestamp offset setting, and fix bug due to UTCO offset not being properly applied. See doc/TIMESTAMPS.rst for more details. Implement FIG2 labels. Fix bug for DAB MP2 in EEP_A. Fix FIG0/24 for DAB+ services. ODR-ZMQ2EDI: fix MNSC endianness swap bug. Pull some RC changes from ODR-DabMod. Implement EDI-over-TCP output. 2019-01-07: Matthias P. Braendli (v2.3.1): Happy new year! Fix TAI bulletin parsing on systems where long is 32 bit. Add configurable URLs to download TAI clock bulletin and rework the download logic. Do not read TAI clock cache file from /tmp anymore, only use /var/tmp. 2018-10-30: Matthias P. Braendli (v2.3.0): Correct FIG0/6 output for services with different ECC. Add support for transmitting empty Linkage Sets. Save leap-second cache to /var/tmp, which doesn't get cleared across reboots. Rework audio level measurement in the statistics server to alleviate some timing-related issues. odr-zmq2edi: Add option to drop late packets. 2018-07-31: Matthias P. Braendli (v2.2.0): Fix delays and FIG repetition burst on announcement switching. Add support for services with different ECC (Signalled in FIG0/9). Improve ODR-ZMQ2EDI statistics. 2018-05-29: Matthias P. Braendli (v2.1.2): A couple of internal changes and fixes for compilation warnings. 2018-03-27: Matthias P. Braendli (v2.1.1): Fix segmentation fault in peak audio statistics calculation. 2018-03-23: Matthias P. Braendli (v2.1.0): Add version string to management server. Introduce slow audio peak statistic. Avoid doing useless copies in the RAW output. 2018-03-01: Matthias P. Braendli (v2.0.0): Configuration file syntax changed for Frequency Information and Other Services settings. Statistics server changes: audio-level peak information is measured over the last second, and not anymore since the last request. Same for buffers, where min/max are measured over thirty seconds. Make nonblock available again for file inputs. 2018-02-09: Matthias P. Braendli (v1.3.3): Add dynamic/static PTy setting to configuration. Add UTF-8 to EBU Latin character set converter for labels.
