CHANGELOG

+1.7.0-dev
+    New features:
+    CMake build system replaces Makefile
+    Use libsndfile for reading and writing audio files
+    Initial DSTAR voice support
+
+1.6.0
+   New features:
+   Auto mutes P25 encrypted signals by default.
+   Raised cosine filters.
+
+   Fixed bugs:
+   Changed the crazy dibit buffer which filled for ever until it
+   ran out of allocated memory then caused a segmentation error. The
+   buffer is now allowed to fill to 90% before being returned to the
+   initial pointer value where it over writes the old samples, it
+   seems to work ok and no segmentation errors now.
+   Input level is now calculated differently, before when it reported 50%
+   the soundcard would be fully overloaded. With the new method aim for 30% inlvl.
+
+1.4.1
+	New features:
+    Several new sync types for existing formats now recognized:
+      Decodes voice from NXDN 4800 (6.25kHz) signals
+  	  Decodes voice from NXDN 9600 (12.5kHz) repeater output
+	  Decodes voice from DMR/MotoTRBO simplex/repeater input
+	  Decodes voice from X2-TDMA simplex/repeater input
+
+	Fixed bugs:
+	renamed "input:" to "inlvl:" to reduce confusion.  This value
+	indicates the audio input level, NOT the "decode success
+	rate".  Voice decode errors are indicated by the errorbars "=".
+
+1.4
+	New features:
+	Decodes voice from NXDN 9600 (12.5 kHz) simplex/repeater input
+	NXDN96 frames enabled by default
+	Improved resistance to NXDN96 sync false positives
+
+	Fixed bugs:
+	.wav file header updated after playing .imb/.amb data files
+	.imb/.amb files now have correct tgid in filename
+
+1.3.1	New features:
+        Support for ProVoice EA sync
+	CTRL-C is now caught so .wav files can be properly closed
+	DSD now shows mbelib version as well as it's own version
+	-R resume option now triggers on any TSDU so control channels can be left
+	in conventional scanlists.
+	Auto output gain now has 0.5 second hold time for faster error burst recovery
+	(was 1.5 seconds)
+        Audio output upsampling function simplified and improved
+
+	Fixed bugs:
+	DSD_Author.pgp now has correct public key (was copy of mbelib_Author key)
+	TGID and SRC are now cleared after TDULC or TDU.
+	Voice error counter is now reset in noCarrier()
+	TGID and SRC were not displaying for X2-TDMA frames
+	Fixed buffer issue in resumeScan()
+	Fixed error in .wav file headers preventing playback on some apps
+
+1.3	New features:
+        Decodes voice from ProVoice signals (requires -fp option)
+	algid and kid are now shown in hex notation
+
+	Fixed bugs:
+	auto output gain now has faster rise time
+	MoTDMA is now correctly labeled X2-TDMA
+
+1.2	New features:
+        Decodes voice for DMR standard (including MOTOTRBO)
+        Full metadata (src, talkgroup, lcinfo, mfid, lcformat, mi, algid, keyid) for X2-TDMA
+        TDMA slot identification for X2-TDMA/DMR/MOTOTRBO
+        Identifies non-voice frame types for X2-TDMA/DMR/MOTOTRBO
+        Frame only (no voice yet) support for 9600 baud NXDN
+	Auto leveling audio output gain (default) and -g option for fixed gain
+	GFSK modulation optimizations and improved C4FM/GFSK/QPSK auto detect
+
+	Fixed bugs:
+	nac was showing wrong ID
+	P25 metadata (lcinfo, mfid, lfcormat, mi, keyid, algid, lsd) are now
+	  printed out in the correct bit order (MSB -> LSB), was reversed.
+	fixed serveral bugs in dsd_upsample.c, with improved quality
+
+1.1	New features:
+	Scanner control options to allow scan resume during certain TDULC
+        Improved upsampling function audio quality
+        Greatly improved handling of X2-TDMA frames
+	Much faster QPSK decision point tracking by default
+
+	Fixed bugs:
+	playMbeFiles was not output to .wav file when -w was given
+    	Now correctly detects/handles Mot and P25 talkgroup formats
+	PDU frames were not detected
+
+1.0.3	Fixed buggy C4FM/QPSK auto detection and added -A option to adjust it.
+
+1.0 Initial release
