 lib_xua Change Log
 ==================
 
-3.5.1
------
+UNRELEASED
+----------
 
-  * FIXED:     Respect I2S_CHANS_PER_FRAME when calculating bit-clock rates
-
-  * Changes to dependencies:
-
-    - lib_spdif: 5.0.0 -> 5.0.1
-
-3.5.0
------
-
-  * ADDED:     Configurable word-length for I2S/TDM via XUA_I2S_N_BITS
-  * ADDED:     Support for statically defined custom HID descriptor
-  * CHANGED:   Rearranged main() such that adding custom code that uses lib_xud
-    is possible
-  * CHANGED:   bNumConfigurations changed from 2 to 1, removing a work-around to
-    stop old Windows versions loading the composite driver
-  * FIXED:     Memory corruption due to erroneous initialisation of mixer
-    weights when not in use (#152)
+  * ADDED:     Configurable word-length for I2S/TDM via XUA_I2S_N_BITS 
+  * FIXED:     Memory corruption due to erroneous initialisation of mixer weights when not in use (#152) 
   * FIXED:     UserHostActive() not being called as expected (#326)
   * FIXED:     Exception when entering DSD mode (#327)
