SCons checkpoint release 1.2.0.d20090223 is now available at the SCons
download page:

        http://www.scons.org/download.php

This checkpoint provides early access to new features and fixes
scheduled for release in SCons 1.3.0.


IMPORTANT:

- This checkpoint release notably contains completely new code for
  detecting installed versions of Microsoft Visual C/C++.  The new code
  has been tested extensively, but it is possible that it will fail to
  find installed versions on configurations that we don't have available
  for testing.  Please report *any* problems with support for Microsoft
  Visual C/C++ as soon as possible so that we can diagnose and fix
  them before releasing SCons 1.3.0.

- Python versions prior to 2.2 are supported by SCons 1.1.0, but are
  officially deprecated and will generate a disableable warning message.
  We plan to remove support for these older versions in SCons 2.0.
  If removing this support would cause a problem for you, please contact
  the [email protected] mailing list.

- The following deprecated features will still be supported in 1.3.0
  but will generate mandatory, non-disableable warnings:

    --  Support for Python versions 1.5, 1.6, 2.0 and 2.1.
    --  The overrides= keyword argument to the Builder() call.
    --  The scanner= keyword argument to the Builder() call.
    --  The BuildDir() function and env.BuildDir() method.
    --  The env.Copy() method.
    --  The SourceSignatures() function and
        env.SourceSignatures() method.
    --  The TargetSignatures() function and
        env.TargetSignatures() method.
    --  The Sig module (now an unnused stub).
    --  The --debug=dtree, --debug=stree and --debug=tree options.
    --  The --debug=nomemoizer option.
    --  The Options object and the related BoolOption(), EnumOption(),
        ListOption(), PackageOption() and PathOption() functions.


WHAT'S NEW IN THIS RELEASE

For a complete description of important changes since other recent
releases, see:

        http://www.scons.org/RELEASE.txt

For a complete list of changes in all releases, see the official
change log:

        http://www.scons.org/CHANGES.txt

We do not recommend that downstream distributions (Debian, Fedora,
etc.) package a checkpoint release, mainly to avoid confusing the
"public" release numbering with the long checkpoint release names.


Here is a summary of all changes since the 1.1.0 release:


NEW FUNCTIONALITY

- SCons now supports batch compilation of Visual Studio C/C++ source
  files when the new $MSVC_BATCH construction variable is set.
- New reserved $CHANGED_SOURCES, $CHANGED_TARGETS, $UNCHANGED_SOURCES
  and $UNCHANGED_TARGETS variables provide finer-grained control
  over what source or targets to pass to a command line.
- A new batch_key= keyword argument to Action object creation supports
  general batched builds.
- A new --warn=future-deprecated option provides advance warnings about
  future deprecated features that still have warnings hidden by default.
- Visual Studio 8 project files can now be generated for 64-bit platforms.

CHANGED/ENHANCED EXISTING FUNCTIONALITY

- $CCFLAGS is no longer included in the default definitions of $CXXFLAGS
  for Visual C/C++ and MIPSpro C++ on SGI (to match other tools and
  avoid flag duplication on C++ command lines).
- The $CCFLAGS variable is now passed to Visual C/C++ precompiled header
  compilation.
- Scanning files encoded in utf-8 and utf-16 for implicit dependencies
  is now supported.
- Linker tools modules now differentiate properly between the SharedLibrary
  and LoadableModule Builders.
- Don't automatically try to build .pdf graphics files for .eps files in
  \includegraphics{} calls in TeX/LaTeX files when building with the PDF
  builder (and thus using pdflatex).
- Setting WINDOWS_INSERT_DEF=0 now disables --output-def when linking
  under MinGW.
- AppendENVPath() and PrependENVPath() now interpret '#' in paths
  relative to the top-level SConstruct directory.
- The message, "scons: Build interrupted." is no printed on error output,
  not standard output.
- Quoted module names in SWIG source files are no handled correctly.
- Suffix-matching for scanners is now case-insensitive on Windows.
- Generated Visual Studio 8 project files now work better with
  IntelliSense, by defining IncludeSearchPath and PreprocessorDefinitions.
- Unnecessary nested $( $) strings around $_LIBDIRFLAGS have been removed
  from the default command lines for the Microsoft linker, the OS/2
  ilink linker and the Phar Lap linkloc linker.
- SCons now internally spells the Windows environment variables
  "SystemDrive" and "SystemRoot" (instead of "SYSTEMDRIVE" and
  "SYSTEMROOT.")

FIXES

- The $CHANGED_SOURCES variable now correctly includes files whose
  corresponding targets don't exist.
- The $CHANGED_SOURCES variable now works correctly with the
  --config=force option.
- $SOURCE and $SOURCES attributes now work even when there are no
  sources specified in the Builder call.
- $SWIGOUTDIR values with spaces now work properly.
- The Borland ilink linker now uses the -e option to specify the output
  file name.
- SCons now correctly identifies shared libraries and shared object files
  in a Repository.
- Implicit command dependencies are detected even when the first argument
  is quoted on the command line.
- #include file names that contain escaped backslashes (\\) are now
  handled correctly.

DOCUMENTATION

- The TestCommon.shobj_prefix variable is now documented.
- Document that the msvc Tool module uses $PCH, $PCHSTOP and $PDB.
- The User's Guide has had numerous typos fixed and other corrections.
