DEPRECATED FUNCTIONALITY + - None + CHANGED/ENHANCED EXISTING FUNCTIONALITY - - 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'. + - SCons handles cache directories a bit differently/ + - Cache files are now stored in 256 subdirectories in the cache directory by + default (this stresses NFS less). Existing cache directories will remain as + current, but SCons will prompt you to run scons-configure-cache which will + allow you to migrate to the new layout, or confirm you want to use the + existing layout. FIXES - - 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. - - 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). - - 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. + - This enhancement resolves missing dependencies with built-in scanners including + SWIG (#2264) and QT - See New Features above + * http://scons.tigris.org/issues/show_bug.cgi?id=2264 IMPROVEMENTS + - None + PACKAGING + - None + DOCUMENTATION + - None + DEVELOPMENT - Thanks to Arfrever Frehtes Taifersar Arahesis, Dirk Baechle, William Blevins, Carnë Draug, Andrew Featherstone, Hiroaki Itoh, Florian Miedniak, William Roberts, Paweł Tomulik for their contributions to this release. + - None + + Thanks to Dirk Baechle, William Blevins, William Deegan, Jakub Pola, Adarsh Sanjeev, Tom Tanner + for their contributions to this release.
