SCons Changelog

What's new in SCons 2.3.0

Mar 4, 2013
  • Added ability to run scripts/scons.py directly from source checkout Hide deprecated --debug={dtree,stree,tree} from --help output Error messages from option parser now include hints about valid choices
  • Cleaned up some Python 1.5 and pre-2.3 code, so don't expect SCons to run on anything less than Python 2.4 anymore
  • Several fixes for runtest.py:
  • exit with an error if no tests were found
  • removed --noqmtest option - this behavior is by default
  • replaced `-o FILE --xml` combination with `--xml FILE`
  • changed `-o, --output FILE` option to capture stdout/stderr output from runtest.py
  • Remove os_spawnv_fix.diff patch required to enable parallel builds support prior to Python 2.2

  • Support building with WiX releases after 2.0
