+Subject: [PATCH] Add support for the new bcg729 API, introduced in version
+ 1.0.2
+
+Starting with version 1.0.2, bcg729 has changed its API to add support
+for G.729B, thus requiring us to adjust our function calls depending on
+which version is installed.
+
+When dealing with the new API, we merely need to add a few parameters to
+disable all G.729B features, namely:
+
+* On the decoder side: When `SIDFrameFlag` is not set, the decoder will
+  behave just like before, decoding the payload as a standard G.729A
+  voice frame (or concealing an erased frame).  The other parameters,
+  `rfc3389PayloadFlag` and `bitStreamLength`, are only of use when
+  dealing with a SID frame sent as per RFC 3389, and are ignored if
+  `SIDFrameFlag` is not set.
+
+* On the encoder side: When `enableVAD` is disabled, the encoder will
+  behave just like before, producing only standard G.729A voice frames.
+  The only API difference is the introduction of `*bitStreamLength`, to
+  return the length of the encoded frame (0, 2 or 10 bytes).  In our
+  case, this will always be 10 bytes just like before; an assert() was
+  added to guarantee this.
+
+Closes #104
