v2.2.0

• CHANGED: Made the FIR coefficient array that is used with the voice fixed
  factor of 3 up and down sampling functions usable from within C files as
  well as XC files.

• CHANGED: Aligned the FIR coefficient array to an 8-byte boundary. This
  ensures that the voice fixed factor of 3 up and down sampling functions do
  not crash with a LOAD_STORE exception.

• ADDED: Missing device attributes to the .xn file of the AN00231 app note.

• Changes to dependencies:

  • lib_logging: 2.0.1 -> 3.1.1

  • lib_xassert: 2.0.1 -> 4.1.0

v2.1.0

• CHANGED: Use XMOS Public Licence Version 1

v2.0.1

• CHANGED: Pin Python package versions
• REMOVED: not necessary cpanfile
