-==============IMPORTANT NOTICE===========
+==============IMPORTANT NOTICE FOR NEXT VERSION V2.5.0==========
+PLEASE READ. CHANGES COMING IN NEXT MAJOR RELEASE V2.5.0
 
-As has been pre-announced in SCons's mailing lists:
+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.

-* https://pairlist2.pair.net/pipermail/scons-dev/2014-December/002107.html
-* https://pairlist4.pair.net/pipermail/scons-users/2015-February/003454.html
+This enhancement resolves missing dependencies
+with built-in scanners including SWIG (#2264) and QT:
+* http://scons.tigris.org/issues/show_bug.cgi?id=2264
 
-We're planning to switch the Node class to using "slots" in the core sources,
-mainly to reduce memory consumption by up to 35% in large build projects.
+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:
 
-This feature has been tested extensively and we don't expect any problems for you.
-However as with all major changes it would be wise to test V2.4.0 when it is
-released. Especially if you are directly using the Node class.
+* 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.

   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. (PR #2180, #2178, #2198)
