#
# Changelog
#
# 1.5
#
# - Added i18n to the midlet
# - Added information of the current playing element
# - Modified debug info levels
#
# 1.4
#
# - Added menu browsing in the phone screen
#
# 1.3
#
# - Cosmetic improvements
# - Send posted event message to OSD
# - Added more Freevo events to the j2me client. It supports now a
# numeric keyboard and display, eject, guide, rec and channel up and down.
#
# 1.2
#
# - Stop advertising only if it's binded. It seems that pyBluez changed its
# behavior and now raises an error if calling stop_advertising when it's
# not advertising.
# - Chris Lombardi reported that the newer phones require to set rfcomm
# sockets to be advertised as a serial port class using the serial port
# profile.
# - The rfcomm socket it is not hardcoded now.
#
# 1.1
#
# - Added support for entering TEXT event from client
# - Added support for volume mixer events
# - Remove polling. Now process_data is made in the bluetooth thread
#
# 1.0
#
# Initial release
