RELEASE 3.0.0 - Mon, 18 Sep 2017 08:32:04 -0700

NOTE: This is a major release. You should expect that some targets may rebuild when upgrading. Significant changes in some python action signatures. Also switching between PY 2.7 and PY 3.5, 3.6 will cause rebuilds.

From William Blevins:

• Updated D language scanner support to latest: 2.071.1. (PR #1924) ​https://dlang.org/spec/module.html accessed 11 August 2016
  • Enhancements:
    • Added support for selective imports: "import A : B, C;" -> A
    • Added support for renamed imports. "import B = A;" -> A
    • Supports valid combinations: "import A, B, CCC = C, DDD = D : EEE = FFF;" -> A, B, C, D
  • Notes:
    • May find new (previously missed) Dlang dependencies.
    • May cause rebuild after upgrade due to dependency changes.
• Updated Fortran-related tests to pass under GCC 5/6.
• Fixed SCons.Tool.Packaging.rpm.package source nondeterminism across builds.

From William Deegan:

• Removed deprecated tools CVS, Perforce, BitKeeper, RCS, SCCS, Subversion.
• Removed deprecated module SCons.Sig
• Added prioritized list of xsltproc tools to docbook. The order will now be as follows: xsltproc, saxon, saxon-xslt, xalan (with first being highest priority, first tool found is used)
• Fixed MSVSProject example code (​http://scons.tigris.org/issues/show_bug.cgi?id=2979)
• Defined MS SDK 10.0 and Changed VS 2015 to use SDK 10.0

• Fixed Bug #3020 - "Download link in user guide wrong. python setup.py install --version-lib broken"

From Ibrahim Esmat:

• Added the capability to build Windows Store Compatible libraries that can be used with Universal Windows Platform (UWP) Apps and published to the store

From Daniel Holth:

• Add basic support for PyPy (by deleting slots from Node with a metaclass on PyPy); wrap most-used open() calls in 'with' statements to avoid too many open files.
• Add main.py for python -m SCons in case it is on PYTHONPATH.
• Always use highest available pickle protocol for efficiency.
• Remove unused command line fallback for the zip tool.

From Gaurav Juvekar:

• Fix issue #2832: Expand construction variables in 'chdir' argument of builders. (PR #463)

From Alexey Klimkin:

• Use memoization to optimize PATH evaluation across all dependencies per node. (PR #345)

From M. Limber:

• Fixed msvs.py for Visual Studio Express editions that would report "Error : ValueError: invalid literal for float(): 10.0Exp".

From Rick Lupton:

• Update LaTeX scanner to understand \import and related commands

From Steve Robinson:

• Add support for Visual Studio 2017. This support requires vswhere.exe a helper tool installed with newer installs of 2017. SCons expects it to be located at "C:\Program Files (x86)\Microsoft Visual Studio\Installer\vswhere.exe" It can be downloaded separately at ​https://github.com/Microsoft/vswhere

From Tom Tanner:

• Allow nested $( ... $) sections

From Paweł Tomulik:

• Fixed the issue with LDMODULEVERSIONFLAGS reported by Tim Jenness (​https://pairlist4.pair.net/pipermail/scons-users/2016-May/004893.html). An error was causing "-Wl,Bsymbolic" being added to linker's command-line even when there was no specified value in LDMODULEVERSION and thus no need for the flags to be specified.
• Added LoadableModule to the list of global functions (DefaultEnvironment builders).

From Manish Vachharajani:

• Update debian rules, compat, and control to not use features deprecated or obsolete in later versions of debhelpers
• Update python version to 2.7 in debian/control

From Richard Viney:

• Fixed PCHPDBFLAGS causing a deprecation warning on MSVC v8 and later when using PCHs and PDBs together.

From Richard West:

• Added nested / namespace tool support
• Added a small fix to the python3 tool loader when loading a tool as a package
• Added additional documentation to the user manual on using toolpaths with the environment This includes the use of sys.path to search for tools installed via pip or package managers
• Added support for a PyPackageDir function for use with the toolpath

From Russel Winder:

• Reordered the default D tools from "dmd, gdc, ldc" to "dmd, ldc, gdc".
• Add a ProgramAllAtOnce builder to the dmd, ldc, and gdc tools. (PR #448)
• Remove a file name exception for very old Fedora LDC installation.
• gdc can now handle building shared objects (tested for version 6.3.0).
• Remove establishing the SharedLibrary builder in the dmd, ldc, and gdc tools, must now include the ar tool to get this builder as is required for other compiler tools.
• Add clang and clang++ tools based on Paweł Tomulik's work.

Note: The only package I know of that uses this, serf, failed to build with version 3.0.0.

[bdubbs@…]

Did you use the 4th sed I added yesterday?

[Armin K]

That worked, thank you. I updated to 3.0.0 before you did on my system, so the sed wasn't present.
