CHANGES COMING IN NEXT MAJOR RELEASE V2.5.0 -RELEASE 2.3.2.alpha.yyyymmdd - NEW DATE WILL BE INSERTED HERE +We're enhancing implicit language scanning functionality to improve +correctness. SCons now honors scanner keys for implicit dependencies +and correctly changes scanner type (if necessary) when traversing +implicit dependency trees. + +This enhancement resolves missing dependencies +with built-in scanners including SWIG (#2264) and QT: +* http://scons.tigris.org/issues/show_bug.cgi?id=2264 + +This enhancement broadens the horizon for handling heterogeneous +data flow environments (E.G. software builds): +* http://article.gmane.org/gmane.comp.programming.tools.scons.user/26596 +Notes: + +* SCons may find new (and correct) dependencies in cross-langauge contexts. +** Update may cause rebuilds, especially in heterogeneous data environments. +** Update may find previously missed dependencies errors (E.G. cycles). +*** Discovered in some QT test cases. +* SCons handles the SCANNERS variable differently. +** Previously, the Install builder would scan implicit dependencies for + a scanner found in SCANNERS (but not for built-in scanners), but now + the Install builder will not scan recursively regardless in order + to optimize Install behaviour and bring orthogonality to previous behaviour. + ++================================================================= + + +RELEASE VERSION/DATE TO BE FILLED IN LATER Please consult the RELEASE.txt file for a summary of changes since the last release and consult the CHANGES.txt file for complete a list of changes since last release. This announcement highlights only the important changes. + Please note the following important changes since release 2.4.0: + - Fix to swig tool - pick-up 'swig', 'swig3.0' and 'swig2.0' (in order). + - Fix to swig tool - respect env['SWIG'] provided by user. + - Fix for Bug # 2791 - Setup.py fails unnecessarily under Jython. + - Fixed license of SVG titlepage files in the context of Debian + packaging, such that they allow for commercial use too (#2985). + - InstallVersionedLib now available in the DefaultEnvironment context. + - Improves orthogonality of use cases between different Install functions. + - Added new configure check, CheckProg, to check for + existence of a program. + - Fix for issue #2840 - Fix for two environments specifying same target with different + actions not throwing hard error. Instead SCons was incorrectly issuing a warning + and continuing. + - Add support `Microsoft Visual C++ Compiler for Python 2.7' + Compiler can be obtained at: https://www.microsoft.com/en-us/download/details.aspx?id=44266 + - Fixed tigris issue #3011: Glob() excludes didn't work when used with VariantDir(duplicate=0) + - Fix bug 2831 and allow Help() text to be appended to AddOption() help. + - Reimplemented versioning for shared libraries, with the following effects + - Fixed tigris issues #3001, #3006. + - Fixed several other issues not reported to tigris, including: + issues with versioned libraries in subdirectories with tricky names, + issues with versioned libraries and variant directories, + issue with soname not being injected to library when using D linkers, + - Switched to direct symlinks instead of daisy-chained ones -- soname and + development symlinks point directly to the versioned shared library now), + for rationale see: + https://www.debian.org/doc/debian-policy/ch-sharedlibs.html + https://fedoraproject.org/wiki/Packaging:Guidelines#Devel_Packages + https://bitbucket.org/scons/scons/pull-requests/247/new-versioned-libraries-gnulink-cyglink/diff#comment-10063929 + - New construction variables to allow override default behavior: SONAME, + SHLIBVERSIONFLAGS, _SHLIBVERSIONFLAGS, SHLIBNOVERSIONSYMLINKS, + LDMODULEVERSION, LDMODULEVERSIONFLAGS, _LDMODULEVERSIONFLAGS, + LDMODULENOVERSIONSYMLINKS. + - Changed logic used to configure the versioning machinery from + platform-centric to linker-oriented. + - The SHLIBVERSION/LDMODULEVERSION variables are no longer validated by + SCons (more freedom to users). + - InstallVersionedLib() doesn't use SHLIBVERSION anymore. + - Enchanced docs for the library versioning stuff. + - New tests for versioned libraries. + - Library versioning is currently implemented for the following linker + tools: 'cyglink', 'gnulink', 'sunlink'. + + Please note the following important changes since release 2.3.6: + - Switch several core classes to use "slots" to reduce memory + usage.
