What are the differences between versions 1.68 and 1.69.11. I do not understand

version 1.69.11 (Dec 19, 2009)

[+] Allowed syntax of "pmovmskb" with 64-bit register destination in long mode.

[-] The code generated for "call eax" instruction was missing prefix in 16-bit
    mode - fixed.


version 1.69.10 (Oct 28, 2009)

[-] Fixed long mode opcode generator to allow absolute addresses to be
    generated with "qword" keyword inside square brackets.


version 1.69.09 (Oct 20, 2009)

[-] Fixed a crash during the symbolic information generation when a "static"
    symbol was encountered.


version 1.69.08 (Oct 04, 2009)

[-] Minor bugfixes.


version 1.69.07 (Oct 03, 2009)

[-] Corrected encoding of "extrq" intruction for some cases.


version 1.69.06 (Sep 29, 2009)

[-] The prefix 67h for "jecxz" and "loopd" instructions in 64-bit mode wasn't
    correctly generated - fixed.

[-] It's no longer possible to define two special segments of the same type
    in ELF executables.


version 1.69.05 (Sep 14, 2009)

[+] Allowed to specify branding value (use 3 for Linux) after the
    "format ELF executable" setting.

[+] Added "intepreter", "dynamic" and "note" keywords for creation of
    special segments in ELF executables.


version 1.69.04 (Sep 7, 2009)

[-] Fixed a bug with REX prefix generation with address of type "rX+rsp".


version 1.69.03 (Aug 03, 2009)

[+] Allowed simplified syntax for "monitor", "mwait", "blendvps", "blendvpd" and
    "pblendvb" instructions.


version 1.69.02 (Jul 04, 2009)

[-] Minor bugfixes.


version 1.69.01 (Jul 01, 2009)

[+] Added "movbe" instruction.

[-] "extractps" no longer generates the double 66h prefix.


version 1.69.00 (Jun 23, 2009)

[+] Extended the syntax of "rept" directive to allow numerical expressions
    to be calculated by preprocessor in its arguments.

[-] The code of assembler (but not data) has been made position-independent, and
    this allowed to use code segmentation in DOS unREAL mode, so the code is
    no longer limited to 64 kilobytes.
