New features:
- new "Configuration" dialog allows changing the main configuration of the program within one window; dialog can be opened by clicking on the new "tools" button in the toolbar or via the main menu, i.e., Options / Configuration; several options which have previously been accessible via the "Options" menu have been moved to this window: GUI font selection, options concerning the system tray, and "hot key" settings
- new option "Clear clipboard automatically": if it is activated, the clipboard will be cleared automatically after a certain time (e.g., 10 seconds) whenever the user copies generated passwords to the clipboard
- new option "Automatic check for updates": enables automatic checks on start-up at regular intervals (i.e., daily, weekly, or monthly); you can also disable this option and manually check for updates (via Help / Check for Updates)
- new "Advanced" password option "Only include characters from custom character set": this option refers to the "Include at least one ..." (letter/digit/ special symbol) options and means that if the latter options are activated, only characters (letters/digits/special symbols) from the user-defined (custom) character set will be included in the generated passwords; for example, if the custom set is "abcdEFGH" and the option "Include at least one lower-case letter" as well as the new option are activated, passwords will contain at least one lower-case letter from the set "abcd"
- new option "Encrypt & Copy" in the context menu of password boxes: encrypts the selected text and copies the ciphertext to the clipboard---no need to copy the plaintext to the clipboard first before calling the "Encrypt clipboard" function
