c7c431f88e bx_instr_mem_data_access became completely obsolete with new stack optimization merged into SVN. 
It already had limited usability before. With stack direct access optimization the callback won't be called for stack accesses as well.
See note by Brian Slechta:

=== Cut Hete ===
While using Bochs as a reference model for simulations, the simulator needs
information about what loads/stores are taking place with each instruction.
Presumably,  that  is  what  the BX_INSTR_MEM_DATA() instrumentation macros
cover (which is the place where our simulator hooks up).

The RETnear_xxx() functions call access_linear() directly, rather than call
read_virtual_xxx()  functions. This is a problem for code making use of the
BX_INSTR_MEM_DATA()   hook  because  it  does  not  get  called  for  these
instructions.  Should  this  be  changed along with some other instructions
that exhibit this?
=== Cut Hete ===

For Bryan's usage bx_instr_lin_access and bx_instr_phy_read/bx_instr_phy_write callbacks should be used.

601bb7e084 - only quit Bochs simulation after pressing the "Quit" button in the runtime 
config dialog. Now the close button and the ESC key let the simulation
  continue in the runtime case (fixes SF bug #3510403).

e7a4a1bec8 surprisingly, opensuse 12.1 requre alignment check support in hardware so I can't disable it by default for all configurations. 
but in case you want a few %% of extra emulation performance - it is still possible to disable it with configure option.
most guests I saw do not use it !

d4688e8b95 - Do not compile support for alignment check (#AC exception) by default 
for CPU emulation performance reasons, the alignment check compilation
    still can be enabled using configure option --enable-alignment-check.

There is no software in the world which enable #AC exception checking, this
x86 feature is completely legacy but its emulation support costs up to 3-5%
emulation speed.

The checking for #AC exception enable still will be done, if

 CPL == 3, EFLAGS.AC = 1 and CR0.AM = 1

but the alignment check is not compiled in, the Bochs will PANIC with corresponding message.
You can press 'always continue' and ignore the PANIC, the simulation will continue as if alignment checking is not enabled.

bd4aa017fe Lazy flags improvement patch by Darek Mihocka - measured 5% speedup everywhere accross the board 
The problem with Parity is it is generally referenced very rarely so the current lazy flags code is not efficient to updated Parify flag only (because it updates low 8 bits of .result value the existing Zero Flag has to be shadowed in .auxbits.
So I flipped it around, to make Parity be shadowed in auxbits.  .result now is only needed to derive Zero Flag, and both Sign and Parify are derived from .result + .auxbits (as Zero Flag is now).  For the 90% of the conditional jumps that are JZ or JNZ, this is a speedup.
Parity is now derived from 8 bits in .result and 8 bits in .auxbits, and Sign is derived from one flag in .result and 1 bit in .auxbits by XOR-ing them all together.  It makes the code sequences for SAHF and POPF simpler too.
