+  A new SCons release, 2.0.1, is now available
+  on the SCons download page:
+
+          http://www.scons.org/download.php
+
+  The primary purpose of this release is to remove support for Python
+  versions prior to 2.4 and streamline the SCons code base using more
+  modern python idioms.
+
+  Here is a summary of the changes since 1.3:
+
+  NEW FUNCTIONALITY
+
+  - There should be no new functionality or bug fixes in this checkpoint.
+
+  DEPRECATED FUNCTIONALITY
+
+  - All features or usages deprecated in 1.3 should have been removed.
+    Uses of formerly-deprecated features should get an error.
+
+  - The BuildDir() method and the build_dir option now get warnings.
+
+  - The SourceCode() function and its associated factory functions have
+    started their deprecation cycle and can have a warning enabled.
+
+  CHANGED/ENHANCED EXISTING FUNCTIONALITY
+
+  - Any Command() or env.Command() calls that use the following Action
+    factory functions will have their targets rebuilt when upgrading
+    from any pre-2.0 release:
+
+        Chmod()
+        Copy()
+        Delete()
+        Mkdir()
+        Move()
+        Touch()
+
+    (The rebuild occurs because the underlying Python class that
+    implements these functions has been changed to a new-style Python
+    class, and that changes the Python byte code and therefore the
+    build signature of the functions.)
+
+  FIXES
+
+  - MSVC/MSVS/SDK support has been improved. A number of issues with
+    determining the correct version and architecture have been resolved.
+
+  - Fix propagation from environment of VS*COMNTOOLS to resolve issues
+    initializing MSVC/MSVS/SDK issues.
+
+  - Fixed a case-sensitivity problem with Fortran modules.
+
+  - Fix the ability to append to default $*FLAGS values (which are
+    implemented as CLVar instances) in a copied construction environment
+    without affecting the original construction environment's value.
+
+  - Updated the TeX command strings to include a /D on Windows in
+    case the new directory is on a different drive letter.
+
+  - Fixed the LaTeX scanner so dependencies are found in commands that
+    are broken across lines with a comment or have embedded spaces.
+
+  IMPROVEMENTS
+
+  - Support for Python versions prior to 2.4 has been removed.  As of
+    this writing, we believe that SCons will still work with Python 2.3,
+    but this is not guaranteed.
+  - Code paths that included special cases for older Python versions have
+    been streamlined.
+  - The code base has been converted to use more modern idioms.  Although
+    we don't have any direct measurements (yet), we believe that SCons
+    startup time should be decreased and the overall code should run faster.
+
+  PACKAGING
+
+  - No changes.
+
+  DOCUMENTATION
+
+  - The entries for SourceCode() and its associated factory functions now
+    state that the functions are deprecated.
+
+  - Document the AllowSubstExceptions() function in the User's Guide.
+
+
+  DEVELOPMENT
+
+  - Code no longer has to be compatible with Python versions back to 1.5.2.
+    Although code is tested with Python 2.3 and is still believed to work,
+    the official new floor is Python 2.4.
+
+  Thanks to Greg Noel, Steven Knight, Dirk Baechle, William Deegan,
+  W. Trevor King, Joe Zuntz, Bauke Conijn, Matt Hughes, Rob Managan, 
+  and Jim Randall for their contributions to this release.
