Trusted QSL V2.6.1 Release Notes
This version of Trusted QSL (TQSL) has a corrections for a defect found since TQSL 2.6 was released.TQSL 2.6.1 can be installed to upgrade any older version of TQSL.Updates since TQSL 2.6: 
This release includes an update to correct a defect that could cause TQSL to “hang” and never complete signing a log when previously submitted QSOs were submitted for signing.
For the Mac platform, TQSL now uses a package file (.pkg) for installing TQSL. This is hopefully easier to use as it is a familiar way to install software for most Mac users.
On all three supported platforms (Windows, MacOS, and Linux), installing TQSL 2.6.1 will replace older versions of Trusted QSL while preserving your Callsign Certificates, Station Locations, and preferences. On Windows, simply run the TQSL 2.6.1 installer, which will automatically uninstall older versions of TQSL (and, if installed, TQSLCert). On Mac OS X, open the package (.pkg) file to install TQSL into your Applications folder. (Note that the “tqsl-legacy” package is for legacy Mac systems – 32 bit Intel and PowerPC.) Direct the installer to “Replace All”, which will uninstall old files. For Linux systems, unpack the tar file and read the INSTALL file for directions.
TQSL 2.6.1 has been “localized” to allow use in the native language of non-English speakers. This could not have been done without the help of the volunteers who have contributed translations for TQSL.

The following list describes the major changes in the v2.6.1 release of Trusted QSL.
TQSL changes
Defects Corrected:
When signing a log with QSOs which were detected as previously uploaded, TQSL would ask the user
how to handle these. If the response was to re-upload those QSOs, TQSL would re-process the log, then
ask again how to handle the previously uploaded QSOs. The only way out of this was to cancel the
signing operation. When this operation was performed by a command-line signing (such as being done
for a logging program) that asked to include all QSOs in the upload (including previously uploaded
QSOs), TQSL would enter a CPU-bound loop and never complete the signing.
This release of TQSL corrects this defect by reverting to the prior behavior.
Major feature Additions:
None.
