Release: WSJT-X 2.4.0 May 24, 2021 ---------------------
WSJT-X 2.4.0 General Availability Release adds new Q65 mode functionality and decoder optimizations and repairs several defects and regressions discovered in the RC4 and v2.3.1 GA releases. Since the release candidates documented below this final release includes the following enhancements and defect repairs.
On MS Windows WSJT-X now ships with a DLL version of the Hamlib library, specifically Hamlib version 4.2. This should allow Hamlib bug fixes to resolved by the user replacing the DLL with an updated version.
Repair a defect with own call decode highlighting when callsigns with a common root are decoded.
Q65 message averaging correctly disabled as be menu option.
Repair a regression with missing timestamps in AlL.TXT for the MSK144 mode.
Repair a defect in the selection of working frequencies matching the current band and mode combination.
WSPR band hopping mode now generates a tune up tone for bands where it is scheduled to transmit.
Repair a long standing defect per band tune and Tx power level memories.
More flexibility for inputting calls into the DX Call field, leading and trailing white space characters are allowed but ignored.
Release: WSJT-X 2.4.0-rc4 Mar 26, 2021 -------------------------
WSJT-X 2.4.0 Release Candidate 4 adds new Q65 mode functionality and decoder optimizations and repairs several defects and regressions discovered in the RC3 and v2.3.0 GA releases.
Correct a problem with display of Q65 sync curves for submodes Q65-120x and Q65-300x.
Audio frequency and decoded message are now saved for up to 100 most recent Q65 decodes. Subsequent double-click on waterfall will search the list for the clicked frequency +/- 10 Hz, recover "DXCall" from the mosr recent decode there, and attempt a decode at that frequency with full "q3" sensitivity.
Use new ADIF recommendations for Q65: mode=MFSK, submode=Q65.
If "Single decode" is unchecked, look for Q65 decodes from accumulated average even after obtaining a single-sequence decode at selected Rx Freq.
For data read from .wav files, display the original UTC (derived from file name) on the waterfall instead of current UTC.
Protect against bounds errors caused by unusual settings on the Wide Graph.
Correct a problem with Split operation in FT4 mode. Thanks to JG1APX.
Release: WSJT-X 2.4.0-rc3 Mar 15, 2021 -------------------------
WSJT-X 2.4.0 Release Candidate 3 adds new Q65 mode functionality and decoder optimizations; repairs defects and regressions discovered in the RC2 and v2.3.0 GA releases.
Repaired a memory corruption related to display of Q65_Sync, particularly nasty on macOS.
Q65 now dissplays two sync curves: orange for the current sequence, red for the accumulated average.
Behavior of "Save decoded" has been corrected.
Repaired a defect that caused crash when displaying the Wide Graph with lower frequency limit set to 0.
Program no longer terminates a transmission when Settings is closed.
Program no longer forces TxFreq to 700 or 1000 Hz when entering Q65 mode or closing Settings. Instead, it highlights TxFreq with red background when its value should be 700 Hz but is not.
Program displays a warning label if a contest mode is active in Q65 mode.
Many updates to User Guide, mostly related to Q65.
Repaired a regression that disallowed a new QSO initiation after an abandoned QSO.
Release: WSJT-X 2.4.0-rc2 Mar 6, 2021 -------------------------
WSJT-X 2.4.0 Release Candidate 2 adds new Q65 mode functionality and decoder optimizations; repairs defects and regressions discovered in the RC1 release.
Q65 sample .WAV files added.
Repair a defect that caused WSJT-X to crash when launched from an icon on macOS.
Repair a crash when using the JT4 mode.
Sequencing improvements to hold transmitted signal report fixed during a QSO.
UI translation updates tnx to Sze-to, VR2UPU, and Michael, 5P1KZX.
Enable the "Call 1st" option for Q65.
Improved Q65 message averaging that linearly averages the first 4 sequences and averages exponentially thereafter using a time-constant of 4 sequences.
Improved macOS post-install instructions, tnx to John, G4KLA.
Enhanced Q65 simulator that generates file names compatible with message averaging, tnx Charlie, G3WDG.
Q65 simulator option to generate single tone waveforms, tnx to Charlie, G3WDG.
Better suppression of birdies in the Q65 decoder.
Blank Q65 decode messages removed.
Automatic low Tx audio offset for the widest Q65 modes to keep Tx signal in transmitter passband, tnx to Charlie, G3WDG.
Improved SNR estimates for Q65 mode.
Decode depths Fast/Normal/Deep are now identical in Q65 mode.
"Save decoded" is now enabled for Q65 mode.
The obsolete ISCAT mode has been removed.
