A new SCons checkpoint release, 2.1.0.alpha.yyyymmdd, is now available
on the SCons download page:
XXX The primary purpose of this release ... XXX
A SCons "checkpoint release" is intended to provide early access to
new features so they can be tested in the field before being released
for adoption by other software distributions.
Note that a checkpoint release is developed using the same test-driven
development methodology as all SCons releases. Existing SCons
functionality should all work as it does in previous releases (except
for any changes identified in the release notes) and early adopters
should be able to use a checkpoint release safely for production work
with existing SConscript files. If not, it represents not only a bug
in SCons but also a hole in the regression test suite, and we want to
hear about it.
New features may be more lightly tested than in past releases,
especially as concerns their interaction with all of the other
functionality in SCons. We are especially interested in hearing bug
reports about new functionality.
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 the changes since 2.0:
- SCons can now automatically embed manifests in Windows executables
and DLLs, by setting WINDOWS_EMBED_MANIFEST in the environment.
- SCons now searches for site_scons dirs in several system-wide
and per-user locations, in addition to the SConstruct top dir.
This should enable much easier use of third-party (non-core)
- List new features (presumably why a checkpoint is being released)
- List anything that's been deprecated since the last release
CHANGED/ENHANCED EXISTING FUNCTIONALITY
- scons --version now prints the path to the SCons package in use
- List modifications to existing features, where the previous behavior
wouldn't actually be considered a bug
- Add initial support for VS/VC 2010
- RPATH is now in LINKCOM rather than LINKFLAGS, so resetting
LINKFLAGS doesn't kill RPATH
- Precompiled headers on Windows no longer break when used with
variant dirs containing spaces.
- Delete can now delete symlinks to directories and broken symlinks
- CPPDEFINES containing dictionaries now work better.
- A problem with using implicit-cache and removing dependencies on
disk is corrected.
- A problem with FS Entries which are dirs and have builders
- A problem with Install() of a dir when the dest dir exists
- Windows subprocess output should now be more reliable.
- The users guide and man page have various fixes.
- Appending to default $*FLAGS in a copied environment
now works properly.
- LaTeX scanner is improved for broken lines or embedded spaces.
- Windows UNC paths (\\SERVER\SHARE\dir) now work much better.
- List fixes of outright bugs
- ParseFlags now supports -std=c++0x and related CXXFLAGS
- ParseFlags now supports -dylib_file from pkgconfig
- New debugging options to print unlink/relinking of variant files
(--debug=duplicate) and preparation of targets (--debug=prepare).
- SCons can now generate MSVS 9.0 and 10.0 Projects and Solutions.
- MSVS Solution generation is improved.
- Fortran 03 is supported (preliminary)
- .sx files are now treated as assembly sources.
- site_scons/site_init.py is now treated as a proper module
with __doc__, __file__ and __name__.
- TeX command strings now work on Windows when the new dir is
on a different drive letter.
- DMD version 2 is supported (using the phobos2 library)
- New --debug=prepare option shows each target as it's prepared
for building; can help when you don't know why a target isn't
- List improvements that wouldn't be visible to the user in the
documentation: performance improvements (describe the circumstances
under which they would be observed), or major code cleanups
- List changes in the way SCons is packaged and/or released
- List any significant changes to the documentation (not individual
typo fixes, even if they're mentioned in src/CHANGES.txt to give
the contributor credit)
- List visible changes in the way SCons is developed
for their contributions to this release.
