II. New features/bugs fixed

 Changed in 8.0.0
 o Implement Feature #123; Added support for Unicode.
   This introduced the following breaking changes:
   - CHAR now wraps at 65536, instead of 256.
   - ASCII and RAWASCII now output numbers from 0-65535 (Unicode BMP).
     This may result in a different number for most characters outside of the
     ASCII range.
   - BACKSLASHEDP now outputs TRUE for characters created from code points in
     the Private Use Area of Unicode, instead of ones in the range of ASCII
     control characters.  Similarly, when RAWASCII inputs such characters
     it outputs large numbers from the Private Use Area, instead of small ones
     from the range of ASCII control characters.
   - If a file is opened in text mode and includes a byte order mark at the
     beginning, then SETWRITEPOS 0 and SETREADPOS 0 now set the position to
     after the byte order mark, instead of before it.
   - OPENREAD, OPENAPPEND, and OPENUPDATE in text modes now infer the character
     encoding from the presence of a byte order mark (BOM) character.  This
     results in different characters being read from any text file which has a
     BOM.  OPENUPDATE honors this encoding when writing, resulting in different
     bytes being written for any file that includes a BOM.
   - When OPENWRITE or OPENAPPEND create text files, they encode all data as
     UTF-8 and write a BOM at the beginning, whereas previously they created
     empty files (no BOM) and encoded data in the system default code page.
   - NETCONNECTSENDVALUE and NETACCEPTSENDVALUE now convert from Unicode to
     the default Windows system code page before transmission.
     NETCONNECTRECEIVEVALUE and NETACCEPTRECEIVEVALUE do the reverse.
   - The "B" output type for DLLCALL uses the lower byte as each character
     in the returned word.  This may result in differences for any bytes
     written to these buffers which are outside the ASCII range.
   - Files created with DRIBBLE now begin with a byte order mark and are
     encoded in UTF-8.  Before, there was no BOM and the file was encoded
     in default system Windows code page.
 o Fix Bug #553; The MESSAGEBOX dialog no longer appear over the commander
   when it's minimized or hidden (and no longers crashes on Windows XP).
 o Fix Bug #552; PORTOPEN now reports an error if the port cannot be opened.
 o Fix Bug #551; Esscaped newline characters now SAVE as "\n" instead of as a
   backslash followed by a literal newline character.
 o Fix Bug #548; BITCUT/BITCOPY/BITPASTE/BITPASTETOBITINDEX now throw errors
   instead of showing a modal dialog boxes and throwing a stopping error.
 o Fix Bug #547; The PORT API now throws port-specific errors instead of
   showing a modal dialog boxes and throwing a stopping error.
 o Fix Bug #546; The NET API now throws network-specific errors instead of
   showing a modal dialog boxes and throwing a stopping error.  It is also
   no longer an error to run NETCONNECTOFF when the client isn't on or to
   run NETACCEPTOFF when the server isn't on.
 o Fix Bug #545; MCI now throws a new MCI-specific error when the MCI
   subsystem returns an error instead of showing a modal dialog box and
   throwing a "Stopping" error.
 o Fix Bug #544; SOUND throws a "doesn't like" error when given bad input
   instead of showing a modal dialog box.  It also no longer plays any
   sound if there's a non-integer member of its input list.
 o Fix Bug #543; POLYSTART and POLYEND now throw "Invalid State" errors
   when called at incorrect times and no longer display dialog boxes.
 o Fix Bug #541; The installer once again aborts if FMSLogo is running.
 o Fix Bug #533; ELLIPSEARC and ELLIPSEARC2 now treat the angles correctly.
   This may change the behavior of programs which give angles that aren't
   multiples of 90 degrees.
 o Fix Bug #530; Using the File API to open the clipboard with anything other
   than OPENREAD or OPENWRITE in text mode no longer crashes.
 o Fix Bug #494; ELLIPSEARC2 now leaves at the point where the ellipse stopped.
   Also, when a negative x.semiaxis (the third input) is given, ELLIPSEARC2
   now draws the arc tangent to the turtle in the oppose direction, instead of
   jumping to the other side of the ellipse.  This may change the behavior of
   programs which give angles that aren't multiples of 90 degrees or negative
   x.semiaxis inputs.
 o Fix Bug #329; SAVE and LOAD can now correctly preserve arrays with CHAR 0,
   CHAR 13, CHAR 26, and CHAR 29.
 o Fix Bug #321; SCROLLBARSET now uses the value returned from :ERRACT when
   the third input (max) isn't larger than the second input (min).
 o Fix Bug #186; NETACCEPTON and NETCONNECTON no longer run the :sendready
   instruction list when the remote host initiates a half-close.
 o Fix Bug #182; NETACCEPTON can now accept multiple connections (in serial)
   without having to call NETSHUTDOWN after each one.
 o Fix Bug #555; Timer event #16, no longer yields by default. This fixes a
   regression introduced when FMSLogo was ported to wxwidgets (7.0.0).
 o Improvements to the manual, including fixing Bug #542.
