This file lists bigger/noteworthy changes, only...


Version 1.3 (upcoming)

dynload:
  o Haiku/x86 build fix
  o dynload fix for PE files that do not contain a symbol export directory (thanks Ashok!)
buildsys:
  o windows/nmake based builds: output library name changes to follow conventions of the native
    platform and be in line with cmake based builds


Version 1.2 (2021/01/23)

dyncall:
  o windows arm64 support (thanks Bernhard!)
  o extended signature with more chars for calling convention switching (only for modes
    that coexist on a platform with other conventions)
  o made "formatted" call interface use calling convention signature chars
  o added helper function dcGetModeFromCCSigChar() mapping callconv sig chars to respective mode
  o removed some unnecessary headers (only contained internal used forward declarations)
  o support clang's integrated as (didn't build on non-Darwin PPC32 platforms)
dyncallback:
  o windows arm64 support (thanks Bernhard!)
  o support clang's integrated as (didn't build on non-Darwin PPC32 platforms)
dynload:
  o fix to build with musl libc
  o support for loading macos >= 11.0.1 (Big Sur) dylibs provided by system's "built-in dynamic
    linker cache of all system-provided libraries" (those dylibs are no longer present on the fs)
  o fix to work on recent Haiku versions (r1 beta versions)
doc:
  o manual now specifying calling convention signature chars
  o dynload(3) note about macos >= 11.0.1 cached dylib support (see above)
  o marked Haiku/x64 as supported and tested
bindings:
  o pydc: Python 3 support, Python 2 unicode support, added get_path function, changing
    'Z' conversions to only immutable types and 'p' to mutable types (and handles), support
    passing None for 'Z' and 'p', bytearray support, support to specify calling convention
  o shdc: can reference own executable now and support for more calling conventions
  o shdc: syscall support
tests:
  o extended callf testcode to test callconv mode switch signature chars (including syscalls)
  o robustness fixes (thanks Bernhard!)
  o dynload_plain test fix on macos >= 11.0.1 (Big Sur)
  o made inode testing of dynload_plain optional, depending on platform support or if macos
    dylib not on fs but provided through system's cache
buildsys:
  o cmake support of armasm64 on windows (thanks Bernhard!)


Version 1.1 (2020/01/11)

dyncall:
  o support for soft-float MIPS o32 & n64 (big- and little-endian, each)
  o x64 System V syscall support
dyncallback:
  o support for soft-float MIPS o32 & n64 (big- and little-endian, each)
dynload:
  o added UTF-8 support for pathnames on windows
  o reliability/stability fix for dlGetLibraryPath() on glibc based platforms (avoiding
    internal use of glibc's bad impl of dlinfo() which doesn't do any error checking at all)
  o Darwin/macos fix for dlGetLibraryPath() to correctly fail on bogus handles (did return
    paths to random libraries under some circumstances, instead of returning an error)
  o support for dlGetLibraryPath() on glibc platforms with glibc vesions <= 2.3.3
  o dlGetLibraryPath() now accepts NULL as argument to return path to executable
  o dlLoadLibrary() on windows: no more auto-suffixing of the .dll file ext anymore, to be
    more in line with other platforms (not affecting OS specific library search behaviour)
doc:
  o more detail in support matrix for bi-endian platforms
  o improvements/corrections to calling convention appendix
  o PPC64 calling convention description
  o MIPS64/N32 calling convention description
  o man page additions for clarity
tests:
  o dynload_plain test extended to test UTF-8 library paths
  o better output for plain test
  o better output and *nix fix for plain_c++ test
buildsys:

  o SPARC32 (v7/v8) support
  o SPARC64 (v9) support
  o PPC32 fixes for (old) Darwin/OS X systems
  o POSIX compliance: fallback for wx alloc on systems that don't have mmap()'s MAP_ANON
  o allocated space used for thunk now always W^X (req. for e.g. OpenBSD >= 6.0)
dynload:
  o major reliability/stability fixes for Mach-O dlSyms* functions to (thanks St├ęphane Mons for help):
    better handle loading dylibs by symlink, relative path, random casing, etc.
    fixes to symbol name lookups that used wrong offsets before
    64-bit platform fixes (was broken on x64 and never supported on others)
  o allowing Mach-O dlSyms* lib to be used standalone (consistent with ELF and PE impls now)
  o simplifications of implemention on Darwin, sharing parts with *nix implementation
  o potentially breaking change on macos/Darwin platforms: all functions now consistently accept or
    return symbol names as they would appear in C code, instead of the raw ones in object files
  o added new function dlGetLibraryPath, allowing lookups of path to library via handle
general:
  o assembly code now built by explicitily asking for non-execstack, for safer/easier integration
    into other projects/builds, where needed; needed b/c of questionable default behaviours of some
    toolchains (thanks Thorsten Behrens for report and analysis)
doc:
  o working html doc generation from TEX sources
  o SPARC32 (v7/v8) calling convention description
  o SPARC64 (v9) calling convention description
bindings:
  o better documentation, removed relative path dependencies, general cleanup
  o python: updated to latest signature format (was still on 0.1)

buildsys:
  o cmake: made to work on systems without C++ compiler (thanks Franklin Mathieu)
