[BRLTTY] 5.0 has been released.

[Dave Mielke]

BRLTTY-5.0 has been released. As usual, it can be downloaded from BRLTTY's web 
site, which is at:

   http://mielke.cc/brltty/

From there, click on "Download", and then on "Current Release".

The most significant change in this release is that brltty is now event-based 
rather than polling-based. Older releases used a huge, central, main loop which 
was run frequently (about 25 times per second), and which was aware of, and had 
to check for, every single task that might need to be performed. With this 
change, brltty is now able to become completely idle whenever it doesn't have 
anything useful to do. See README.Polling for details.

Major Changes:
   Conversion from frequent regular polling to event-based scheduling.
   The speech driver now runs in its own thread.
General Changes:
   The --message-delay brltty option has been renamed to --message-timeout.
   The -Q [--quiet-if-no-braille] brltty option has been added.
   The -U [--update-interval=] brltty option has been removed.
   The CLIP_SAVE and CLIP_RESTORE commands have been added.
   The PWGEN command has been removed.
   The FREEZE toggle can now be explicitly set to on or off.
   The confirmation tune is played twice if an explicit toggle is already set.
   Braille driver selection using the Bluetooth device name is now supported.
   A Bluetooth device address may now contain dashes (-) instead of colons (:).
   The "bth:" and "bluez:" device qualifier aliases are no longer supported.
   Braille device identifiers may now contain parameters (see README.Devices).
   Lots of improvements to Android support have been made.
