+
+    * examples/sndfile-resample.c

+    due to libsndfile's in ability to seek in a FLAC file during write.
+
+    * src/samplerate.h tests/termination_test.c
+    Revert change that moved the src_ratio field to the start of SRC_DATA
+    struct. This change does have some merit, but is not worth it considering

+    * src/common.h
+    Add WARN_UNUSED macro.
+
+    * src/src_sinc.c

+
[phone]  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
+
+    * src/samplerate.c
+    Fix a bug in src_callback_read() reported by Mark Deggeller. Data retreived

+    Add fields saved_frames and saved_data to SF_PRIVATE struct for storing
+    data between sucessive calls to src_callback_read().

[phone]  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
+
+    * tests/calc_snr.c
+    SNR calculation was being screwed up because the peak detector was
+    mistaking side lobes caused by the windowded FFT as noise/aliasing peaks.
+    Therefore added code to wipe out the troughs between peaks which erases
+    the side lobe peaks without affecting the noise/aliasing peaks.
+
+    * tests/multi_channel_test.c

+
[phone]  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>
+
+    * src/src_sinc.c
+    Phase one or refactoring. Replace use of a circular buffer to hold short
+    window of data with a linear buffer.
+    Linear buffer requires that data is periodically copied from the end if
+    the buffer back to the beginning. However, it also means that the
+    calc_output() function no longer needs to calculate the next data index
+    modulo the buffer length.
+    Since the data index is calculated 40 times (minimum) per output sample,
+    and the copy from end of buffer to start of buffer is done every 1000 or
+    so output samples, this change results in a significant speedup (up to
+    about 50% improvement for SRC_SINC_FASTEST).
+    Memory use has increased somewhat (max 6k per channel per converter) due
+    to this fix, but that should go down again during next phase of
+    refactoring.
+
+    * examples/varispeed-play.c
+    Fixed a bug where data_in and data_out buffers were overlapping.
+
[phone]  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

+    New function force_efence_banner().
+
