[Bill Deegan]

  A new SCons release, 3.0.3, is now available on the SCons download page:

          https://scons.org/pages/download.html


  Here is a summary of the changes since 3.0.1:

  NEW FUNCTIONALITY

    - Properly support versioned shared libraries for MacOS.  We've also
introduced two
      new env variables APPLELINK_CURRENT_VERSION and
APPLELINK_COMPATIBILITY_VERSION which will specify
      what is passed to the linkers -current_version and
-compatibility_version flags.  If not specified
      they will be derived from SHLIBVERSION as such:
          - APPLELINK_CURRENT_VERSION = SHLIBVERSION
          - APPLELINK_COMPATIBILITY_VERSION = all but the last digit in
SHLIBVERSION with .0 appended.
          Note that the values of the above will be validated. Valid format
for either APPLELINK variable is
          X[.Y[.Z]] where 0 <= X <= 65535, 0 <= Y <= 255, 0 <= Z <= 255.
    - Add flag must_exist to SConscript() call to fail on missing script.
        Not failing on missing script is now considered deprecated, and the
first instance will print a
        deprecation message.
    - Add xz compression format to packaging choices.
    - Add Textfile/Substfile to default environment. (issue #3147)
    - Added virtualenv support. A new function Virtualenv() determines
whether
        SCons runs in a virtualenv. The search PATH may also be extended to
        prefer executables from the current virtualenv over the ones
provided by
        base environment. New option --enable-virtualenv provided to import
some
        virtualenv-related variables to SCons and extend every
env['ENV']['PATH']
        automatically. New option --ignore-virtualenv disables this. Two
        environment variables, SCONS_ENABLE_VIRTUALENV and
        SCONS_IGNORE_VIRTUALENV are supported for the same purpose.

  DEPRECATED FUNCTIONALITY

    - Going forward calling SConscript on a non-existing SConscript file
will issue a warning.  Currently
      it will issue a deprecation notice.

  CHANGED/ENHANCED EXISTING FUNCTIONALITY

    - Recognize new java 9, 10, 11 (as 9.0 and 10.0, 11.0)

  DOCUMENTATION
    - Update some doc examples for Py3: map() now returns an iterable
      instead of a list.

  FIXES

    - Fix issue #2980 with credit to Piotr Bartosik (and William Blevins).
This is an issue where using
         TimeStamp-MD5 Decider and CacheDir can yield incorrect md5's being
written into the .sconsign.
         The difference between Piotr Bartosik's patch and the current code
is that the more complicated
         creation of file to csig map is only done when the count of
children for the current node doesn't
         match the previous count which is loaded from the sconsign.
