+Changes from gsm-codec-lib-r1 to gsm-codec-lib-r2:
+
+* Libgsmfrp evolved from version 1.0.0 to version 1.0.2; please see
+  doc/FR1-Rx-DTX for a detailing listing of libgsmfrp changes.
+
+* Some new utilities have been developed for studying AMR: see
+  doc/AMR-study-utils for more information.
+
+* The subject of conversions between 16-bit 2's complement linear PCM and 8-bit
+  A-law and mu-law PCM formats (G.711) has been thoroughly studied, the findings
+  have been documented in doc/PCM8-conversions, and some new command line
+  utilities have been added, described in the same article.
+
+* Many new table generators have been added to the dev subdirectory; some of
+  them may be useful to other software developers.
+
+* pcap utilities have been split off to a separate rtp-debug-utils repository;
+  this split was made so that those utilities can be developed freely while the
+  gsm-codec-lib repository remains under strict release process control.
