 # ChangeLog:
 # ============================================================================
-# 4.9 - 20180408
+# 4.9 - 20181114
 # - Implemented generic playback engine support. You can use -k to specify your playback command, and -K for the command options
+# - fix: when exporting pbx files doesn't rename 44khz.wav to mp3
 
 # 4.8 - 20170909
 # - Implemented cksum hash file names when creating tts files from cli (thanks to Jean-Marc Leglise for the idea). So every txt/tts file will always have an unique file name based on contents.
