Там это, вышла стабильная версия этого чудного компилятора. 26 февраля еще, правда, а новости так и не было.
SDCC 3.7.0 Feature List:
-     Changed putchar() prototype from void putchar(char) to int putchar(int) to improve standard-compliance and allow error reporting.
 -     Various speed improvements in stm8 backend - Dhrystone score more than doubled, resulting in SDCC achieving the highest Dhrystone scores among STM8 C implementations.
 -     Various speed improvements for multiplications resulting in SDCC achieving the highest Coremark scores among STM8 C implementations.
 -     Declarations in for loops (ISO C99).
 -     64-bit integers (long long) for the mcs51 and ds390 backends (now long long is fully supported in SDCC except for the pic14 and pic16 backends).
 -     Full _Bool support for mcs51 and ds390 backend (now _Bool is fully supported in SDCC regardless of backend).
 -     Additional wide character library functions: mbstowcs() and wcstombs(), btowc() and wctob(), wcscmp(), wcslen().
 -     Changed PRNG for rand() from LCG to xorshift to improve speed and quality.
 -     Support for Small-C calling convention on the callee side (i.e. function definitions with Small-C calling convention).
 -    The obsolete macro SDCC (which used to contain the version number encoded as an integer) has finally been removed (except for mcs51, where it will survive a little bit longer for SiLabs IDE compability).
 -    New devices supported by simulator (TLCS-90, and the 517, F380, XC88X, DS320 mcs51-variants along with dual-dptr and MDU support).
 -    Timer, UART (incl. interrupt) and I/O support in STM8 simulator.
 -     Simulator support for banked memory and bit banding.
 -     Various simulator improvements: Conditional breakpoints, breakpoints by function name from SDCC debug output, OMF input, VCD output, simulator interface for simulated program and new operators in expressions.
 -     Deprecated --nojtbound and the corresponding pragma.
 -     Faster register allocator reduces compilation time by about 25% (does not apply to mcs51, ds390 which use a different register allocator).
 -     Execution count guessing and use of execution count guesses in stm8 register allocation improve optimization for code speed.
 -     Changed getchar() prototype from char getchar(void) to int getchar(void) to improve standard-compliance and allow error reporting.
 -    Type qualifiers in array parameters (ISO C99).
static in array parameters (ISO C99).
 -    Improved support for DWARFv2 debug info in ELF output (stm8, hc08, s08).
 -    Various improvements in z80/z180/gbz80/tlcs90/r2k/r3ka code generation, in particular for mixed 16-/32-bit code.
 -     __z88dk_fastcall function pointer support for --reserve-regs-iy.
 -     tlcs90 is now a fully supported backend, no longer work in progress.
 -     --data-seg to specify the segment for non-initialized data in the z80, z180, gbz80, tlcs90, r2k and r3ka backends.
 -     New methods to obtain tree-decompositions of control-flow graphs improve compilation time / code-quality trade-off (when SDCC is built with support for the treedec library).
 -     Additional general utility functions: qsort(), strtol(), strtoul().
 - Numerous other new features and bug fixes are included as well.
