• Fix use-after-free triggered by set_frequency() #421

Full Changelog: v3.0...v3.0.1

Version 3.0

New features

• The "HERE Images" stream, which contains traffic and weather images, is now decoded. The nrsc5 application dumps out these images when the --dump-aas-files <directory> argument is used. Images are also reported via the new NRSC5_EVENT_HERE_IMAGE API event. #415

Bug fixes

• Reading IQ input from stdin, or writing IQ/audio/HDC output to stdout now works correctly on Windows. #393
• Ctrl+C now terminates the nrsc5 program on Windows. #394
• Occasional audio corruption on low-SNR signals has been fixed. #396
• Startup time is reduced, especially on Raspberry Pi. #411
• The limit on the total number of audio & data services has been increased from 8 to 16. #413

API improvements

• Elastic buffering has been implemented. Audio output via the NRSC5_EVENT_AUDIO API event now occurs much more frequently, and with very little jitter. #399
• A new NRSC5_EVENT_AUDIO_SERVICE API event reports information about audio streams, using data extracted from PDU headers. #402
• When a station stops sending an emergency alert, a new NRSC5_EVENT_EMERGENCY_ALERT API event is generated to indicate that no alert is in effect. (A new NRSC5_EVENT_SIS API event is also generated, with the emergency alert fields cleared.) #408
• The excessively large NRSC5_EVENT_SIS API event has been deprecated, and broken down into a more granular set of events (NRSC5_EVENT_STATION_ID, NRSC5_EVENT_STATION_NAME, NRSC5_EVENT_STATION_SLOGAN, NRSC5_EVENT_STATION_MESSAGE, NRSC5_EVENT_STATION_LOCATION, NRSC5_EVENT_AUDIO_SERVICE_DESCRIPTOR, NRSC5_EVENT_DATA_SERVICE_DESCRIPTOR, and NRSC5_EVENT_EMERGENCY_ALERT) #409
• Duplicate SIG services & components are now removed from the table reported in the NRSC5_EVENT_SIG API event. #412
• The NRSC5_EVENT_PACKET, NRSC5_EVENT_STREAM, and NRSC5_EVENT_LOT API events now include pointers to the corresponding SIG service & component records, thereby eliminating the need for applications to cache information from the NRSC5_EVENT_SIG API event. #414
