The new K4 beta release will be of interest to anyone using Remote. T/R
delays have been reduced, and numerous changes have been made to host
commands.
This revision also has two significant improvements for RTTY users:
unshift-on-space is now implemented, and the idle time at the end of
transmissions has been truncated.
For details on these and other enhancements, see full release notes below.

========================================================

NEW FEATURES
------------
- REMOTE: AUDIO STREAMING LATENCY AND T/R TIMES REDUCED. Average latency
should be lower and more stable over time. Results will still vary with
internet connection quality.
- SPLIT MODE ALWAYS TURNED OFF AT POWER-UP. Several customers reported
inadvertently leaving SPLIT on. Turning it off on any fresh start is the
safer alternative.
- ADDED UNSHIFT-ON-SPACE (UOS) for RTTY RX, now an industry standard. At
present UOS cannot be turned off, though we could add a menu entry for it
if required. Field-test group consensus was that it wasn't needed. (NOTE:
UOS is already being done in TX mode.)
- SHORTENED RTTY "DIDDLES" (idle time) at the end of RTTY transmissions
terminated by an EOT ('|') character. Was ~650 ms, now ~100 ms. This is
useful for RTTY contesting.
- Extensive updates in support of the K4/0.
- Updated built-in operating manual to rev. D11.
---------
BUG FIXES
---------
- Remote: If you send a key or paddle then hit PTT shortly after, return to
RX mode may have been subject to an excessive delay.
- Improved system anomaly detection/messaging, specifically for LPA and DSP
errors.
- PSK and RTTY via keyer paddle now inserts characters into TX decode
window (like CW).
--------------
FOR DEVELOPERS
--------------
- RX; command will now terminate a KY command if sent directly after (e.g.,
KY VVVV;RX;).
- TX;DE999;RX; correctly results in a 10 second wait before going back to
RX;. The only exception is while KYW ("Wait") is active, e.g.:
TX;KYWOOO;DE999;FA;RX;TB;. In this case the RX; will be processed, and the
FA;TB; responses will be delayed by 10 seconds.
- BR; now returns the baud rate of RS232 port.
- MEDF (menu definitions) for IDs 107 and 109 cleaned up, removing
extraneous fields.
- BI, MX, RO$, and RT$ info now sent in response to RDY;
- Remote: Any SL set command now clears the streaming audio buffers, even
if the SL value isn't changed. NOTE: Normally buffer contents will
stabilize over time without any user intervention. The UI does not provide
a way to do this directly.
- Remote: RX; command while in receive no longer clears the RX audio buffer
or causes the radio to go into TX in CW mode when not sending CW.
- Remote: We no longer ignore client-requested command processing delays
(e.g., DEnnn;).
