uBee512 v6.0.0 is released. uBee512 is an emulator for the Microbee Z80 Premium/Standard FDD and ROM based microcomputers.

uBee512 v6.0.0 Changelog:
* Revise video output to only redraw those parts of the screen that have changed, improving emulator performance.
* Changes made to 'keystd.c' to lower 'stopshift' and 'makeshift' values to work in Early Word (earlier version).
* Windows binary packages now ships with SDL-1.2.15 (final) DLL which replaces the older SDL-1.2.14 version. The SDL (Windows) changelog is here: https://www.libsdl.org/release/changes-1.2.html
Fixed:
* LibDsk build for Linux was using wrong build prefix so was being built against an older LibDsk build. Should now be LibDsk-1.4.2
* In memmap.c comment out the printf("file=...") line in sram_load().
* Fixed sram_save() in memmap.c to ignore an open new file error, now it only warns if using verbose mode.
