Bart Oldeman has this announcement:
Special thanks go to Luchezar Georgiev for some good bug hunting. The device driver and UMB regressions of kernel 2030 are fixed. Download it from sourceforge or from ibiblio.

Here are only a few of the changes:
* add extra low disk buffer to avoid HMA problems with certain device drivers.
* point to a correct environment for INSTALL= (fixes problems with xmsdsk).
* change device driver error code check (using S_ERROR | S_DONE) (fixes problem with the SystemSoft PCMCIA socket services driver)
* Fix a problem that occurred with some Compaq and Fujitsu/Siemens highend equipment.
* Correct problem with multiple UMBs (bug #1671)
* main.c: there aren't lastdrive open file handles but a maximum of 20.
* config.c, main.c: Fix bug in block device driver init of DPBs (bug #1969, TDSK problem)

Kernel 2031说是有不少bugfix，不过我却发现它的兼容性怎么比Kernel 2030还低呀。。比如说Kenel 2031和ECHO.SYS和MS-DOS的EMM386.EXE均不兼容，而Kernel 2030就可以呢。。

我把kernel.sys升级到2031了，freecom也是最新的.082pl2。还没没有发现什么问题，因为我们只用最简单的dos环境，程序是watcom c+dos4gw的，不需要emm386之类。
不过下载的最新的beta9rc1在vmware中安装了几次都不成功。先是丫format的问题仍然没有解决，后来用msdos格式化，但发现安装时copy文件fail。还没有找台闲机器完整测试。
