SCons - a software construction tool Release Notes
This is SCons, a tool for building software (and other files). SCons is
implemented in Python, and its "configuration files" are actually Python
scripts, allowing you to use the full power of a real scripting language
to solve build problems. You do not, however, need to know Python to
use SCons effectively.
So that everyone using SCons can help each other learn how to use it
more effectively, please sign up for the scons-users mailing list using
the instructions on the following page:
RELEASE 1.3.1 - Sun, 25 Jul 2010 15:57:38 -0700
Please consult the CHANGES.txt file for a list of specific changes
since last release.
Please note the following important changes since release 1.3.0:
-- VC9.0 Express should no longer throw exceptions -- VC should gracefully downgrade from amd64 to x86 if no amd64 compilers are available and user didn't request via TARGET_ARCH a specific target architecture. -- Fixed case-sensitivity problem with scanners in cygwin python -- Fixed MSVC initialization issue where PATH,LIB,LIBPATH were leaking from the os.environ into the Environment. -- Fixed propagating VS*COMTOOLS & COMSPEC from external environment if the Environment object doesn't have them defined. -- 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.
Please note the following important changes in this release:
-- DEPRECATED FEATURES WILL GENERATE MANDATORY WARNINGS IN 1.3.0 In keeping with our deprecation cycle, 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, 2.1, 2.2, and 2.3. -- 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. The mandatory warnings will be issued in order to make sure users of 1.3.0 notice *prior* to the release of SCons 2.0.0, that these features will be removed. In SCons 2.0.0 these features will no longer work at all, and will instead generate specific fatal errors when anyone tries to use them.
Thank you for your interest, and please let us know how we can help
improve SCons for your needs.
