New features - support for RDB hardfiles was implemented; while creating a new hardfile from the WinFellow GUI still creates “plain” hardfiles, a Rigid Disk Block can be created using tools like HD Toolbox - the default naming scheme for filesystem devices has been changed from DHx: to FSx: to avoid naming conflicts with existing RDB hardfiles - a 64 bit build is now provided; the NSIS installer will install either the 32 or 64 bit version depending on the operating system that is used Bug fixes - improved handling of hardware interrupts and blitter delays; fixes freezes that could occur during installation of Workbench in earlier 0.5.x versions - fix wrong selection of render function after return from menu when application did not write to bplcon0 every frame; fixes garbled graphics in a Legend cracktro when returning from menu - replaced alternating patterns for unmapped memory with proper random numbers - CLR reads before write; fixes loading of Outrun and a fast-mem test in Last Ninja 2 - improve delay caused by logging in screen-mode enumeration (could amount to many seconds with multiple screens) - running in an environment with very slow graphics framerate, like a VM, could cause a deadlock; set wait time after event reset to avoid race condition - fix an issue where screenshots would occasionally not be taken in Direct3D graphics mode; this may also have impacted the ability to use Amiga Forever’s clipping editor - fix an issue where applying a new model preset would leave multiple blitter radio buttons selected Maintenance updates - project files were updated to Visual Studio 2019 using the toolset v141_xp - the February 2010 DirectX SDK dependency was eliminated - IPF Access API files were updated to the latest version, and support for it was enabled in 64 bit builds

- Added auto-updater - Screenshots are now automatically saved to a folder - Niche optimizations - Bug fixes & minor improvements

DOSBox 0.74-3 has been released A new version has been released, with the focus on security: Fixed that a very long line inside a bat file would overflow the parsing buffer. (CVE-2019-7165 by Alexandre Bartel) Added a basic permission system so that a program running inside DOSBox can't access the contents of /proc (e.g. /proc/self/mem) when / or /proc were (to be) mounted.(CVE-2019-12594 by Alexandre Bartel) Several other fixes for out of bounds access and buffer overflows. Some fixes to the OpenGL rendering. Full changelog: Implement basic file access control for files available from within the emulation, so that programs running inside DOSBox can't access /proc (e.g. /proc/self/mem). (CVE-2019-12594) Unify unmounting code and add some protections against out of bound access when DOS_DRIVES is not 26. Use correct type for return value of strlen. Change scan3x to a bit brighter. Fix unitialized access to some isoDrive fields and improve stability when switching CD images. Small fix to hq3x. Fix 256 colour mode encoding in zmbv.dll. Some small aliassing fix. Change SET to check the size of the MCB when adding variables. Fixes hangs with Norton Commander. Check buffer length before doing tab completion. Correct buffer overflow with very long lines in bat files. (CVE-2019-7165) Correct the boundary check for the internal programs array. Increase stability in max cycles mode by increasing the lower bound. Fix command prompt in windows 3.11 with dynrec core. Fix Win64 dynrec core. Always clear buffers before drawing in OpenGL mode. Fixes artifacts with drivers that have more than 2 buffers and overlays. Fix red border that appeared when scaling the image in OpenGL mode with Nvidia on Linux and Mac. Change default output to opengl on Mac, as surface is very slow there in 64 bit. Add workaround for the mouse unlocking problem with X.org 1.20.1. Fix table access when USE_FULL_TLB is undefined (non-default configuration). Several fixes to prevent compilation errors. Update Visual studio file to fix missing files from 0.74-2. In an ideal world 0.75 would have been released already, but some bugs took way longer than expected as well as real life demanding a lot of attention. It's still being worked on.
