This release fixes a few bugs that slipped through when releasing 0.71.
Here a list of the changes:

    * Some bugfixes and speedups to the 64 bit recompiling core.

    * Fixed sign flag on soundblaster dma transfers (Space Quest 6 intro)

    * Fixed Dreamweb.

    * Improved speed unlocking when running cycles=max.

    * Fixed a crash related to the tab completion in the shell.

    * Improved aspect correction code. Should now be like how a real monitor handles it.

    * Fixed a bug in the xms status report code. (Blake Stone 1.0 shareware)

    * Added a lot more keyboard layouts.

    * Fixed crash related to changing the scaler before a screen was created.

    * Hopefully fixed compilation on *bsd.

    * Enabled auto cpu core selection for recompiling core as well.

    * Made the used joystick selectable when 4axis is specified.

此版本主要是修正了一些bug，关于dosbox介绍，翻一下本区老帖即可，此为官方正式版，适合对dos环境和使用比较熟悉的人
