The two goals for TQSL 2.1 were to make it accessible and to make it localizable.

Several changes in the TQSL user interface were made to help the GUI better interact with screen readers and other accessibility interfaces. While many of these changes aren't apparent to the typical user, there are some minor changes in work flow that you may notice.

For localization, much of the TQSL GUI and messages can now be translated into local languages. For this beta, there are machine translations included that came from Google Translate. They're probably of very poor quality, but serve as a proof of concept.

Other major changes:

  • If a user has only one station location, then there's no prompt to ask them to select what location to use.
  • Station locations can be set up with callsign "[None]". When a user uses that to sign, they're prompted for the appropriate call. This allows people who have had multiple callsigns for a given QTH to enter the data for the location once.
  • TQSL now recognizes the ADIF <SUBMODE> tag and attempts to map that to modes recognized by LoTW. Fully supporting <SUBMODE> will require changes in the LoTW configuration file.
  • TQSL now detects when another instance is busy signing a log (waiting on a user to respond to a prompt) and a command line logger is requested to sign a different log. The command line invocation of TQSL no longer "hangs" the command line signing operation and instead returns an error.
  • TQSL now properly handles non-ASCII characters in folder names. Previous versions relied upon the DOS compatibility "short" file names, which are not enabled by default on Windows 8.
  • Startup performance improvements, particularly for stations with large numbers of callsign certificates.
