-------------------------
This release repairs several MAP65 defects and omissions discovered in
the first release candidate, it also repairs some regressions in
WSJT-X, including some in the Hamlib library.
Changes for MAP65:
- Implement linear drift compensation for Q65 mode when FTol >100 Hz.
- Implement a "Max drift" UI control for Q65.
- Repair a regression which omitted signal meter scales.
Remember that the WSJT-X 2.5.0 package includes MAP65 3.0.0. Changes
in the package since WSJT-X 2.5.0-rc1 include the following
enhancements and defect repairs:
MAP65:
- Compute polarization angle for Xpol systems and display to nearest
degree
- Compute and display the recommended Tx polarization
- Protect against Fortran bounds errors in several places
- Insert leading 0 when needed in UTC hours and minutes on waterfall
- Wideband Q65 synchronization corrected to include single-polarization
mode
- Corrected a one-symbol (0.6 s) delay in Q65 Tx audio
- Basic instruction document for building an MS Windows portaudio DLL
for MAP65 users who are unable to use WDM/KS drivers for their
multi-channel sound cards.
Changes for WSJT-X:
- Implement linear drift compensation for Q65 mode when FTol >100 Hz.
- Implement a "Max drift" UI control for Q65.
WSJT-X (including the decoder for Q65 used by MAP65):
- Increase maximum DT to 5.5 s when EME decoding is enabled in Q65
- Fix generation of Tx5 message when "hiscall" has suffix /P or /R.
- Improve width management of GUI's band-selection combo box
- Restore plotting of Q65 sync curve after a q3 decode
- Disable selection of "View | Message Averaging F7" for modes
other than JT4 and JT65
- Switching to Q65 mode now defaults to "Decode | Fast"
- Repair a long standing regression with message generation for
72-bit modes when using a compound callsign.
- Message averaging window no longer available in Q65 mode as it is
not relevant.
- Improvements to the frequency/band combo box pop up list width to
address a regression occurring in recent releases.
- Updated CTY database.
- Repair a defect in diagnostic logging that could cause crashes on
some platforms.
- Repair a defect which failed to strip leading and trailing spaces
on input of callsigns during validation.
- Hamlib updates including repair of defects with PTT handling on a
separate serial port via rigctld, delayed PTT with Elecraft K3
series rigs, and support for the Icom IC-575 rig.
- Updated CTY.DAT database
