General:
- All tools are now 64-bit only, except the installer. You can still build for both 32-bit and 64-bit Windows.
- The Add-In SDK is now part of the main Setup (not a separate Setup).
- Switched from Microsoft CodeView to Pelles C Debug Info.
- Added support for new C17 standard (mainly affects the help file).
- Added new (private) C runtime functions (see the help file).
- Added support for UTF-16LE and UTF-8 encoded text files in the C runtime.
- Updated a bunch of Windows include files.
IDE:
- Added support for project modes. Default modes are Release and Debug.
- Added support to the source code editor for search/replace of text in all project/workspace files.
- Added better support for clean project and clean workspace.
- Revised backup file handling in the source code editor.
- Added composite file to File Differences.
- Added debugger support for Pelles C Debug Info, dropped support for Microsoft CodeView info.
- Added debugger support for thread descriptions (the application must provide them).
- Improved debugger stack walking, especially for X86.
- Revised layout of debugger register tab.
- Completely rewritten ZIP file helper library, with f.e. support for UTF-8 encoding.
- Added slightly better support for installer projects.
- Added support for reading old PPM images (simply because I needed it).
- Removed support for WinHelp files.
Compiler:
- Added support for Pelles C Debug Info, dropped support for Microsoft CodeView info.
- Added option /ARCH for X64, with choice of SSE2, AVX, or AVX2.
- Added new alias analysis (f.e. the restrict qualifier will have more effect than before).
- Added support for unrolling trivial loops.
- Revised support for atomics and implementation of stdatomic.h.
- Revised support for variable arguments and implementation of stdarg.h.
- Added support for __has_include() operator in preprocessor.
- Changed __declspec(noretchk) to __declspec(nodiscard) (fewer functions with important return value than unimportant ones).
- Added attempt at some basic Spectre mitigations.
- Added constant folding of many more SIMD intrinsics.
- Added better reporting of source line for inlined code.
- Added option /Zd to disable a warning (the option can be used multiple times, for different warnings).
- Revised spilling in register allocator to make it less likely to die of register starvation (on X86).
- Minor improvements to suggestion for misspelled name.
- Removed experimental analyzer for strict aliasing (too many false positives). May get revisited in the future.
- Added more intrinsics, optimizations, warnings, bugfixes, you name it!
- Added minimal support for some new Stupid Microsoft Tricks (TM).
- Changed default architecture to X64.
Macro assembler:
- Added support for Pelles C Debug Info, dropped support for Microsoft CodeView info.
- Added some new instructions.
- Changed default architecture to X64.
Linker:
- Added support for Pelles C Debug Info, dropped support for Microsoft CodeView info.
- Added support for UTF-8 encoded .drectve sections.
- Removed linker option /OPT:WIN98, /OPT:NOWIN98.
- Raised default OS version to 6.0 for console and windows programs.
- Fixed problem linking drivers.
Dump utility:
- Added dump of Pelles C Debug Info.
- Added support for some new instructions in the disassembler.
Registry editor:
- Added support for importing and exporting .REG files.
- Added support for Registry key permissions.
Install builder:
- Added commands SectionGroup, SectionGroupEnd, MixedBitmap and UninstallCaption.
- Added variables $ESTIMATEDSIZE, $INSTALLDATE, $LASTERROR, $LASTERRORTEXT, $PROFILE, USERPROFILES, $USERPROGRAMFILES, $USERPROGRAMFILESCOMMON and $WIN64.
- Added command line option /OUT.
