BBC模擬器BeebEm發佈新版，更新如下：

* Rewrote debugger command interpreter:
  - Supports command names longer than one character
  - Added command history (up/down arrows when command box focused)
  - Commands are now implemented using function pointers, should be more expandable.
  - More descriptive help - type 'help', 'help <command>' or 'help <addr>'.
  - Better label support - any word in command arguments preceded with a '.' is interpreted as a label and resolved before the args are passed to the command handler.
* Fixed bug that prevented checkboxes enabled/disabled by command from actually taking effect.
* Expanded debug memory map support:
  - Maps can now be stored for each ROM, just put a .map file with the same name as the ROM in the ROM's directory, for example BeebFile\BBC\os12.map corresponds to BeebFile\BBC\OS12.ROM, and address queries (via 'help <addr>') will return info from the currently selected ROM's map.
  - Address info queries now understand shadow/private/sideways RAM in different machines.
  - Cleaned up MemoryMap.txt and moved it to BeebFile\BBC\OS12.map
* Added 'state m' command to get state of memory (ACCCON and Shadow/Sideways RAM info)
* Added routines for extracting header info from paged ROMs, and 'state r' command to dump this info in the debugger.
* Break now shows previous Program Counter address as well as the current address. This is useful for finding where the source of a jump was.
* A bit of a hack to allow debug window to go behind main window, but also come to foreground with main window.
* Added option to enable DirectX smoothing when only in teletext mode.
