+lib_src change log
+==================
+
+2.5.0
+-----
+
+  * ADDED: VPU enabled ASRC and SSRC providing a 2x speed improvement
+  * ADDED: Asynchronous FIFO with phase detector and PID rate controller for
+    ASRC usage
+  * ADDED: Support for XCommon CMake build system
+  * FIXED: Function pointer annotation avoid stack corruption when using
+    multiple instances of SSRC or ASRC.
+
+  * Changes to dependencies:
+
+    - lib_logging: 3.1.1 -> 3.2.0
+
+    - lib_xassert: Removed dependency
+
+2.4.0
+-----
+
+  * ADDED: Support for building the core ASRC code in the C emulator as a
+    library
+  * ADDED: Auto-generated ASRC and SSRC performance plots in documentation
+  * ADDED: Documentation warning about overflow in XS3 optimized SRC components
+  * CHANGED: Documents built under Jenkins instead of Github Actions
+  * CHANGED: Tested against fwk_core v1.0.2 updated from v1.0.0
+
+2.3.0
+-----
+
+  * ADDED: XS3 VPU optimised voice fixed factor of 3 upsampling/downsampling
+  * ADDED: XS3 VPU optimised voice fixed factor of 3/2 upsampling/downsampling
+  * CHANGED: OS3 uses firos3_144.dat coefficients by default inline with model
+  * CHANGED: Replaced xmostest with pytest for all SRC automated tests
+  * CHANGED: Used XMOS doc builder for documentation
+  * CHANGED: Golden reference test signals now generated automatically by CI
+  * RESOLVED: Linker warning on channel ends
+  * REMOVED: AN00231 ASRC App Note. See github.com/xmos/sln_voice/examples
+  * CHANGED: Increased precision of the fFsRatioDeviation used in the C emulator
+    from float to double
+  * CHANGED: Allow for 64 bits in the rate ratio passed to asrc_process() for
+    extra precision
+
+  * Changes to dependencies:
+
+    - lib_logging: 2.0.1 -> 3.1.1
+
+    - lib_xassert: 2.0.1 -> 4.1.0
+
+2.2.0
+-----
+
+  * 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.
+  * ADDED: Minimal cmake support.
+
+2.1.0

+
+  * CHANGED: Use XMOS Public License Version 1
+
+2.0.1
+-----
+
+  * CHANGED: Pin Python package versions
+  * REMOVED: not necessary cpanfile
+
+2.0.0
+-----
+
+  * CHANGED: Build files updated to support new "xcommon" behavior in xwaf.
+
+1.1.2
+-----
+
+  * CHANGED: initialisation lists to avoid warnings when building
+
+1.1.1
+-----
+
+  * RESOLVED: correct compensation factor for voice upsampling
+  * ADDED: test of voice unity gain
+
+1.1.0
+-----
+
+  * ADDED: Fixed factor of 3 conversion functions for downsampling and
+    oversampling
+  * ADDED: Fixed factor of 3 downsampling function optimised for use with voice
+    (reduced memory and compute footprint)
+  * ADDED: Fixed factor of 3 upsampling function optimised for use with voice
+    (reduced memory and compute footprint)
+
+1.0.0
+-----
+
+  * Initial version
+
+  * Changes to dependencies:
+
+    - lib_logging: Added dependency 2.0.1
+
+    - lib_xassert: Added dependency 2.0.1
