更新日誌

v9.0.6 (2019-11-27):

Major improvements

New interface controls in the main window of the program and in the editor window. DevExpress controls are used instead of TB2K/TBX/SpTBX
New way of handling the user interface layout configuration. Also, there is a new file – “userdef.xml” , instead of “tbuser.def” previously used

New features

Possibility of recording and logging of the time it takes to open the following configuration dialogs: “Account Properties”, “Folder Properties”, “Sorting Office/Filters”, and the following windows: message editor, the folder view. The time is measured if the following command-line parameters are used to run The Bat!: “/BENCHMARK_STARTUP_TIME” and/or “/STARTUP_TIMING_LOG”. With the “/STARTUP_TIMING_LOG” option only, the results will only be saved to the ex_log.file, while with “/BENCHMARK_STARTUP_TIME” they will be displayed on the screen as a message dialog

Improvements

Updated spell checker dictionaries (Hunspell) for the following languages: Danish, Dutch, English (British), English (US), French, Greek, Hungarian, Latvian, Polish, Portuguese (Brazil), Portuguese (Portugal), Romanian, Spanish, Swedish
Removed PGP internal implementation (RFC-1991) from The Bat!
There is now a random delay before sending the TLS alert code to a remote computer in order to prevent eventual timing attacks
