- 0.5.0 - initial release
- 0.5.9 - signal ABI bugfix, various cleanup and fixes:
- sigset_t was wrongly defined as 1024 bytes instead of 1024 bits,
- breaking the intended ABI compatibility with the LSB/glibc sigaction
- structure. users should upgrade immediately and rebuild any libraries
- or object files that might be using the incorrect definitions.
- improved security against DoS with tcb shadow passwords by checking
- that the file opened was really an ordinary file.
- fixed a bug in the implementation of atomic ops that could have
- allowed the compiler to incorrectly reorder them (in practice, gcc
- with the default settings on i386 was not reordering them).
- greatly improved conformance to the C and POSIX standards regarding
- what the standard header files make visible. _POSIX_C_SOURCE is now
- needed to get POSIX functions in standard C headers, and _XOPEN_SOURCE
- or _GNU_SOURCE are required to get XSI interfaces or GNU extensions,
- respectively.
- many internal improvements have been made to the syscall-related code
- in preparation for porting to x86_64 and other archs.
- 0.6.0 - x86_64 port, various important bugs fixed
- new x86_64 (amd64) architecture port, contributed by Nicholas J. Kain,
- along with PORTING guide. source tree layout and build system have
- been improved to accommodate further ports.
- various bugs that were introduced while making the headers respect C
- and POSIX namespace standards have been fixed. conformance to the
- standards has been improved.
- fixed an inefficiency in qsort that triggered a bug (occasionaly
- internal compiler error) in some versions of gcc.
- fixed a major bug in the printf %n specifier that prevented it from
- working and caused memory corruption.
