v3.0.0

Fixed

• Fixed defects that were causing state corruption when removing a merge receiver, during a network reset, and during initialization.
• Fixed defects that were causing state corruption or crashes when a sACN API call failed.
• Fixed variations in DMX merger output based on the order levels and priorities were entered.
• Fixed a defect that was causing sources to be excluded from sampling during lwIP initialization.
• Fixed incorrect sequence numbers being sent by the source.
• Fixed incorrect write to reserved field in universe discovery packets.
• Fixed unsorted universe lists being sent in universe discovery packets.
• Fixed a defect that was causing redundant multicast sends.
• Fixed wrapping issues with remote source and merger source handles.
• Fixed flickering after the sampling period.
• Removed the const qualifier on the unicast destinations array in the source universe settings.
• Fixed a couple memory leaks.
• Audited usage of memory and network resources and fixed a number of issues.

Added

• Updated the merge receiver callback interface with additional information and new callbacks.
• Added priority data to the sacn::MergeReceiver::Source structure.
• Implemented socket-per-NIC mode on Windows to avoid edge-case performance issues caused by the IP_PKTINFO sockopt.
• Added sacn_config.h options to opt out of SO_REUSEPORT and/or SO_RCVBUF, set the send buffer size, and disable internal DMX merger buffers.
• Changed name of sacn_config.h option to SACN_MERGE_RECEIVER_ENABLE_IN_STATIC_MEMORY_MODE.
• Implemented a new example application demonstrating use of the sACN Source C++ API.
• Added ability to specify that no network interfaces should be used, or to specify the same interface multiple times.
• Added new assertion handling (with logging in release mode) throughout the entire codebase.
• Added logging for send statistics and new error cases, adjusted verbosity of existing logs.

Changed

• Revised network reset handling so that new sampling periods will only occur on new interfaces.
• Improved zero-initialization of internal state memory in static mode.
• Made refactors to bring in a new version of EtcPal.
• Adjusted the source implementation to send universes from lowest to highest.
• Made PAP keep-alive interval separately configurable.
• Made various performance improvements to the DMX merger.
• Improved performance when sending many universes by spacing out the sending of start codes 0x00 and 0xDD.
• Added handling for more setsockopt error cases.

v2.0.2

Fixed

• Fixed numerous defects that were causing static receiver limits (e.g. universe and source counts) to be reached sooner than expected.
• Fixed a defect that was causing universe discovery packets with under 40 universes to be incorrectly discarded by the source detector.

Added

• Added a function to the merge receiver for retrieving information about a source on the universe.
• Enabled the installation of PDB files in the lib folder during a CMake install.

v2.0.1

Fixed

• Fixed a CMake bug that would cause sACN to fail to configure when EtcPal has already been added
  manually using add_subdirectory()

v2.0.0

Added

• New core module APIs: Source, DMX Merger, Merge Receiver, Source Detector
• New C++ wrapper APIs: Source, Receiver, DMX Merger, Merge Receiver, Source Detector

Changed

• Revamped the API to conform more closely with our other open-source libraries.
• Numerous performance enhancements derived by comprehensive testing in ETC products.
