What's New in This Release: [ read full changelog ]

· when composing new message and trying to edit existing message from the queue, ask the user whether to replace the text
· fix program freeze with redo function ( issue #160 )
· add new gateway [SK]Orange (platený), fix paid accounts problem with [SK]Orange gateway ( issue #158 , thanks Tomáš Kováčik and Ladislav Matěj)
· fix problems with downloading gateways containing non-ascii characters in their names, mainly on Windows ( issue #164 )
· fix swapping of sms sender name and sms sender number when reloading esmska ( issue #176 )
· fix problems with charset in messages for some gateways
· fixed [CZ]t-zones gateway ( issue #177 )
· semantics of debug modes changed a little
· program output is saved to file console.log into user configuration directory (easier bug reporting!)
· display an error dialog if there is some uncaught program exception caused by Esmska (easier bug reporting!)
· create checkbox in settings to enable debug mode (even easier bug reporting!)
· all gateway script files must now contain only ascii characters in filenames, which solves problems on some platforms (guess which) and in some tools ( issue #159 )
· changed type of encryption of gateway passwords → program startup is faster! (about 600ms less on my 2GHz CPU)
· improved appearance on Mac OS X (unified toolbar support)
· removed many icons from main menu to improve readability
· exit button is displayed in toolbar only when program notification icon is visible (then window close does not quit the program and therefore the button makes sense)

· display main window properly when iconified and started again in Windows ( issue #182 )
