openSMILE 3.0.1

Version 3.0.1 is a patch release consisting of a collection of bug fixes and minor improvements and internal refactorings.
In this version, a number of previously deprecated and obsolete components have been removed.

Added

• eGeMAPSv02 feature set config which fixes two missing features in the LLD output
  that are mentioned in the GeMAPS paper.

Changed

• Introduced a standard_data_output_no_lld_de.conf.inc include file to make the GeMAPS configs
  not need to define a fake lld_de level.
• Removed -ffast-math and /fp:fast compiler flags to improve the reproducability
  of output across compilers and systems.
• SMILExtract no longer logs to a file by default.
• Many internal refactorings and cleanups.

Removed

• Removed SEMAINE-related components and binaries.
• Removed obsolete cJniSink and cJniMessageInterface components.
• Removed unused internal support for integer data in data memory levels.

Fixed

• Fixed a race condition when multiple openSMILE instances are initialized at the same time
  in separate threads.
• Fixed a race condition in smile_reset which could lead to the function failing when
  multiple openSMILE instances are used concurrently.
• Multiple fixes and improvements to the condition variable implementation.
• Fixed a rare race condition in cExternalSource and cExternalAudioSource.
• Fixed incorrect Wave file headers written by cWaveSink when sample format was set to 32-bit float.
• cArffSink now correctly escapes special characters in the output (e.g. instance names).
• Fixed a build issue preventing the android-template sample app from being buildable
  on Windows and macOS.
• Various other minor fixes and tweaks.
