>> --------
>> - Added support for UDP connections.

>> - Added option to select the sound to be played when new received data is detected.
>> - Improved behavior when the connection options window is closed by pressing OK and the CoolTerm display is currently paused. The display will now only unpause if settings that require a display refresh were changed.
>> - Fixed bug that caused a failure to include the window position in the string returned by the GetAllParameters scripting command.
>> - Fixed bug that caused a failure to set a parameter when SetParameter is called with "KeywordFormat" as the parameter name.
>> - Fixed a bug that caused the "Pause" toolbar buttons to not be updated properly when certain action trigger automatic unpausing of the display.
>> - Minor update to X and YMODEM receive code to send the initial NCGByte more frequently so that a file transfer can start more quickly.
>> 
>> v2.5.0a0
>> --------
>> - [macOS] macOS Tahoe compatibility and updated to SDK 26.
>> - [Linux] changed code to use setserial to set custom baudrates. On systems where setserial is not installed, CoolTerm will fall back to using stty.
>> - Replaced "Convert non-printable Characters" with the option to "Ignore", "Convert", or "Remove".
>> - Added context menu item to status bar for resetting port statistics.
>> - Added menu item to quick menu for resetting port statistics.
>> - The window title will now show the sizes of the text/hex/chart displays.
>> - Added "Open Recent" menu item to Session menu.
>> 
>> v2.4.1b0
>> --------
>> - Fixed bug that keeps the "View/Clear Data" menu item disabled, even when the receive buffer contains data.
>> - Fixed bug that caused the font preview in the connection options to not always be updated correctly when "condense line spacing" and font size was changed in the GUI.
>> - Fixed bug that could lead to an execution in WinTerm.EnableMenuItems due to RXBuffer being NIL.
>> - [Linux] fixed issue that prevented macros from being executed from the "Macros" tool button.
