Release: WSJT-X 2.2
June 1, 2020
-------------------
WSJT-X 2.2 is a program upgrade that provides a number of new features
and capabilities. Here is a brief summary; for further details see
the notes for candidate releases 2.2.0-rc1, -rc2, and -rc3, below, and
of course the updated WSJT-X 2.2 User Guide.
- Significant improvements to the decoders for FT4, FT8, JT4, JT65,
and WSPR.
- New format for "EU VHF Contest" Tx2 and Tx3 messages
When "EU VHF Contest" is selected, the Tx2 and Tx3 messages (those
conveying signal report, serial number, and 6-character locator)
now use hashcodes for both callsigns. This change is NOT backward
compatible with earlier versions of _WSJT-X_, so all users of EU
VHF Contest messages should be sure to upgrade to version 2.2.0.
- Accessibility
Keyboard shortcuts have been added as an aid to accessibility:
Alt+R sets Tx4 message to RR73, Ctrl+R sets it to RRR.
As an aid for partial color-blindness, the "inverted goal posts"
marking Rx frequency on the Wide Graph's frequency scale are now
rendered in a darker shade of green.
- User Interface Translations have been enabled. Translations are
now available for Catalan, Spanish, Japanese, Chinese, and Hong
Kong Chinese. Additiional languages will follow, when available.
- Minor enhancements and bug fixes
"Save None" now writes no .wav files to disk, even temporarily.
An explicit entry for "WW Digi Contest" has been added to
"Special operating activities" on the "Settings | Advanced" tab.
Contest mode FT4 now always uses RR73 for the Tx4 message.
The Status bar now displays the number of decodes found in the
most recent Rx sequence.
