+RELEASE 3.1.1 - Mon, 07 Aug 2019 20:09:12 -0500
 
-RELEASE 3.0.1 - Mon, 14 Nov 2017 08:28:09 -0700
+  From William Deegan:
+    - Remove obsoleted references to DeciderNeedsNode which could cause crash when using --debug=explain
 
-  From Thomas Berg:
-    - Fixed a regression in scons-3.0.0 where "from __future__ import print_function" was imposed
-      on the scope where SConstruct is executed, breaking existing builds using PY 2.7.
+  From Jason Kenny
+    - Add Fix and test for crash in 3.1.0 when using Decider('MD5-timestamp') and --debug=explain
+
+  From Ben Reed:
+    - Added -fmerge-all-constants to flags that get included in both CCFLAGS and LINKFLAGS.
+
+  From Mathew Robinson:
+    - Fix issue #3415 - Update remaining usages of EnvironmentError to SConsEnvironmentError
+      this patch fixes issues introduced in 3.1.0 where any of the
+      following would cause SCons to error and exit:
+        - CacheDir not write-able
+        - JSON encoding errors for CacheDir config
+        - JSON decoding errors for CacheDir config
+
+
+RELEASE 3.1.0 - Mon, 20 Jul 2019 16:59:23 -0700
+
+  From Joseph Brill:
+    - Code to supply correct version-specifier argument to vswhere for
+      VS version selection.
 
   From William Deegan:
-    - Fix issue where code in utility routine to_String_for_subst() had code whose result was never
-      properly returned.  
-      (Found by: James Rinkevich https://pairlist4.pair.net/pipermail/scons-users/2017-October/006358.html )
-    - Fixed Variables.GenerateHelpText() to now use the sort parameter. Due to incorrect 2to3 fixer changes 
-      8 years ago it was being used as a boolean parameter.  Now you can specify sort to be a callable, or boolean
-      value. (True = normal sort). Manpage also updated.
-    - Fixed Tool loading logic from exploding sys.path with many site_scons/site_tools prepended on py3.
-    - Added additional output with time to process each SConscript file when using --debug=time.
-    - Fix broken subst logic where a string with "$$(abc)" was being treated as "$(abc) and the
-      logic for removing the signature escapes was then failing because there was no closing "$)".
-      This was introduced by a pull request to allow recursive variable evaluations to yield a string
-      such as "$( $( some stuff $) $)".
+    - Enhanced --debug=explain output. Now the separate components of the dependency list are split up
+      as follows:
+
+      scons: rebuilding `file3' because:
+           the dependency order changed:
+           ->Sources
+           Old:xxx	New:zzz
+           Old:yyy	New:yyy
+           Old:zzz	New:xxx
+           ->Depends
+           ->Implicit
+           Old:/usr/bin/python	New:/usr/bin/python
+    - Fix Issue #3350 - SCons Exception EnvironmentError is conflicting with Python's EnvironmentError.
+    - Fix spurious rebuilds on second build for cases where builder has > 1 target and the source file
+      is generated. This was causing the > 1th target to not have it's implicit list cleared when the source
+      file was actually built, leaving an implicit list similar to follows for 2nd and higher target
+              ['/usr/bin/python', 'xxx', 'yyy', 'zzz']
+      This was getting persisted to SConsign and on rebuild it would be corrected to be similar to this
+              ['zzz', 'yyy', 'xxx', '/usr/bin/python']
+      Which would trigger a rebuild because the order changed.
+      The fix involved added logic to mark all shared targets as peers and then ensure they're implicit
+      list is all cleared together.
+    - Fix Issue #3349 - SCons Exception EnvironmentError is conflicting with Python's EnvironmentError.
+      Renamed to SConsEnvironmentError
+    - Fix Issue #3350 - mslink failing when too many objects.  This is resolved by adding TEMPFILEARGJOIN variable
+      which specifies what character to join all the argements output into the tempfile. The default remains a space
+      when mslink, msvc, or mslib tools are loaded they change the TEMPFILEARGJOIN to be a line separator (\r\n on win32)
+    - Fix performance degradation for MD5-timestamp decider.  NOTE: This changes the Decider() function arguments.
+      From:
+          def my_decider(dependency, target, prev_ni):
+      To:
+          def my_decider(dependency, target, prev_ni, repo_node):
+      Where repo_node is the repository (or other) node to use to check if the node is out of date instead of dependency.
+
+  From Peter Diener:
+    - Additional fix to issue #3135 - Also handle 'pure' and 'elemental' type bound procedures
+    - Fix issue #3135 - Handle Fortran submodules and type bound procedures
+
+  From Adam Gross:
+    - Upgraded and improved Visual Studio solution/project generation code using the MSVSProject builder.
+      - Added support for Visual Studio 2017 and 2019.
+      - Added support for the following per-variant parameters to the builder:
+        - cpppaths: Provides per-variant include paths.
+        - cppdefines: Provides per-variant preprocessor definitions.
+
+  From Michael Hartmann:
+    - Fix handling of Visual Studio Compilers to properly reject any unknown HOST_PLATFORM or TARGET_PLATFORM
+
+  From Bert Huijben:
+    - Added support for Visual Studio 2019 toolset.
+
+  From Mathew Robinson:
+    - Update cache debug output to include cache hit rate.
+    - No longer unintentionally hide exceptions in Action.py
+    - Allow builders and pseudo-builders to inherit from OverrideEnvironments
+
+  From Leonard de Ruijter:
+    - Add logic to derive correct version argument to vswhere
+
+  From Lukas Schrangl:
+    - Enable LaTeX scanner to find more than one include per line
+
+  From Mats Wichmann:
+    - scons-time takes more care closing files and uses safer mkdtemp to avoid
+      possible races on multi-job runs.
+    - Use importlib to dynamically load tool and platform modules instead of imp module
+    - sconsign: default to .sconsign.dblite if no filename is specified.
+      Be more informative in case of unsupported pickle protocol (py2 only).
+    - Fix issue #3336 - on Windows, paths were being added to PATH even if
+      tools were not found in those paths.
+    - More fixes for newer Java versions (since 9): handle new jdk directory
+      naming (jdk-X.Y instead of jdkX.Y) on Windows; handle two-digit major
+      version. Docstrings improved.
+    - Fixups for pylint: exception types, redefined functions,
+      globals, etc.  Some old code removed to resolve issues (hashlib is
+      always present on modern Pythons; no longer need the code for
+      2.5-and-earlier optparse). cmp is not a builtin function in Py3,
+      drop one (unused) use; replace one.  Fix another instance of
+      renaming to SConsEnvironmentError. Trailing whitespace.
+      Consistently use not is/in (if not x is y -> if x is not y).
+    - Add a PY3-only function for setting up the cachedir that should be less
+      prone to races. Add a hack to the PY2 version (from Issue #3351) to
+      be less prone to a race in the check for old-style cache.
+    - Fix coding error in docbook tool only exercised when using python lxml
+    - Recognize two additional GNU compiler header directory options in
+      ParseFlags: -iquote and -idirafter.
+    - Fix more re patterns that contain \ but not specified as raw strings
+      (affects scanners for D, LaTeX, swig)
+
+
+RELEASE 3.0.5 - Mon, 26 Mar 2019 15:04:42 -0700
+
+  From William Deegan:
+
+    - Fix Issue #3283 - Handle using --config=force in combination with Decider('MD5-timestamp').
+      3.0.2 in fix for issue #2980 added that deciders can throw DeciderNeedsNode exception.
+      The Configure logic directly calls the decider when using --config=force but wasn't handling
+      that exception.  This would yield minimally configure tests using TryLink() not running and
+      leaving TypeError Nonetype exception in config.log
+    - Fix Issue #3303 - Handle --config=force overwriting the Environment passed into Configure()'s
+      Decider and not clearing it when the configure context is completed.
+    - Add default paths for yacc tool on windows to include cygwin, mingw, and chocolatey
+    - Fix issue #2799 - Fix mingw tool to respect SHCCCOMSTR, SHLINKCOMSTR and LDMODULECOMSTR
+    - Fix Issue #3329 - Add support for MS SDK V10.0A (which is commonly installed with VS2017)
+    - Fix Issue #3333 - Add support for finding vswhere under 32 bit windows installs.
+
+  From Maciej Kumorek:
+    - Update the MSVC tool to include the nologo flag by default in RCFLAGS
+
+From Daniel Moody:
+    - Change the default for AppendENVPath to delete_existing=0, so path
+      order will not be changed, unless explicitly set (Issue #3276)
+    - Fixed bug which threw error when running SCons on windows system with no MSVC installed.
+    - Update link tool to convert target to node before accessing node member
+    - Update mingw tool to remove MSVC like nologo CCFLAG
+    - Add default paths for lex tool on windows to include cygwin, mingw, and chocolatey
+    - Add lex construction variable LEXUNISTD for turning off unix headers on windows
+    - Update lex tool to use win_flex on windows if available
+
+  From Mats Wichmann:
+    - Quiet open file ResourceWarnings on Python >= 3.6 caused by
+      not using a context manager around Popen.stdout
+    - Add the textfile tool to the default tool list
+    - Fix syntax on is/is not clauses: should not use with a literal
+    - Properly retrieve exit code when catching SystemExit
+    - scons-time now uses context managers around file opens
+    - Fix regex patterns that were not specified as raw strings
+
+  From Bernhard M. Wiedemann:
+    - Do not store build host+user name if reproducible builds are wanted
+
+
+RELEASE 3.0.4 - Mon, 20 Jan 2019 22:49:27 +0000
+
+  From Mats Wichmann:
+    - Improve finding of Microsoft compiler: add a 'products' wildcard
+      in case 2017 Build Tools only is installed as it is considered a separate
+      product from the default Visual Studio
+    - Add TEMPFILESUFFIX to allow a customizable filename extension, as
+      described in the patch attached to issue #2431.
+    - scons.py and sconsign.py stopped working if script called as a symlink
+      to location in scons-local location.
+    - Fix issue running scons using a symlink to scons.py in an scons-local dir
+    - Doc updates around Default(), and the various *TARGETS variables.
+
+  From Daniel Moody:
+    - Improved support for VC14.1 and Visual Studio 2017, as well as arm and arm64 targets.
+      Issues #3268 & Issue #3222
+    - Initial support for ARM targets with Visual Studio 2017 - Issue #3182 (You must set TARGET_ARCH for this to work)
+    - Update TempFileMunge class to use PRINT_CMD_LINE_FUNC
+
+  From Tobias Herzog
+    - Enhance cpp scanner regex logic to detect if/elif expressions without whitespaces but
+      parenthesis like "#if(defined FOO)" or "#elif!(BAR)" correctly.
+
+
+RELEASE 3.0.3 - Mon, 07 Jan 2019 20:05:22 -0400
+  NOTE: 3.0.2 release was dropped because there was a packaging bug. Please consider all 3.0.2
+        content.
+
+  From William Deegan:
+    - Fixes to packaging logic.  Ensuring the SCons.Tool.clangCommon module is added
+      to the release packages.
+    - Modify scons.bat script to check for scons python script without .py extension if no file
+      scons.py exists. This enables an all platform wheel to work.
+
+  From Mats Wichmann:
+    - Update doc examples to work with Python 3.5+:  map() now returns an iterable instead of a list.
+
+
+RELEASE 3.0.2 - Mon, 31 Dec 2018 16:00:12 -0700
+
+  From Bernard Blackham:
+    - Fixed handling of side-effects in task master (fixes #3013).
+
+  From William Deegan:
+    - Remove long deprecated SCons.Options code and tests.  This removes BoolOption,EnumOption,
+      ListOption,PackageOption, and PathOption which have been replaced by *Variable() many years ago.
+    - Re-Enable parallel SCons (-j) when running via Pypy
+    - Move SCons test framework files to testing/framework and remove all references to QMtest.
+      QMTest has not been used by SCons for some time now.
+    - Updated logic for mingw and clang on win32 to search default tool install paths if not
+      found in normal SCons PATH.  If the user specifies PATH or tool specific paths they
+      will be used and the default paths below will be ignored.
+      - Default path for clang/clangxx : C:\Program Files\LLVM\bin
+      - Default path for mingw         : C:\MinGW\bin and/or  C:\mingw-w64\*\mingw64\bin
+      - Key program to locate mingw    : mingw32-make (as the gcc with mingw prefix has no fixed name)
+    - Fixed issue causing stack trace when python Action function contains a unicode string when being
+      run with Python 2.7
+    - Add alternate path to QT install for Centos in qt tool: /usr/lib64/qt-3.3/bin
+    - Fix Java tools to search reasonable default paths for Win32, Linux, macOS.  Add required paths
+      for swig and java native interface to JAVAINCLUDES.  You should add these to your CPPPATH if you need
+      to compile with them.  This handles spaces in paths in default Java paths on windows.
+    - Added more java paths to match install for Centos 7 of openjdk
+    - Fix new logic which populates JAVAINCLUDES to handle the case where javac is not found.
+    - Fix GH Issue #2580 - # in FRAMEWORKPATH doesn't get properly expanded. The # is left in the
+      command line.
+    - Fix issue #2980 with credit to Piotr Bartosik (and William Blevins).  This is an issue where using
+      TimeStamp-MD5 Decider and CacheDir can yield incorrect md5's being written into the .sconsign.
+      The difference between Piotr Bartosik's patch and the current code is that the more complicated
+      creation of file to csig map is only done when the count of children for the current node doesn't
+      match the previous count which is loaded from the sconsign.
+    - Fix issue # 3106 MSVC if using MSVC_BATCH and target dir had a space would fail due to quirk in
+      MSVC's handling of escaped targetdirs when batch compiling.
+    - Fix GH Issue #3141 unicode string in a TryAction() with python 2.7 crashes.
+    - Fix GH Issue #3212 - Use of Py3 and CacheDir + Configure's TryCompile (or likely and Python Value Nodes)
+      yielded trying to combine strings and bytes which threw exception.
+    - Fix GH Issue #3225 SCons.Util.Flatten() doesn't handle MappingView's produced by dictionary as return
+      values from dict().{items(), keys(), values()}.
+    - Fix GH Issue #3241 - Properly support versioned shared libraries for MacOS.  We've also introduced two
+      new env variables APPLELINK_CURRENT_VERSION and APPLELINK_COMPATIBILITY_VERSION which will specify
+      what is passed to the linkers -current_version and -compatibility_version flags.  If not specified
+      they will be derived from SHLIBVERSION as such:
+      - APPLELINK_CURRENT_VERSION = SHLIBVERSION
+      - APPLELINK_COMPATIBILITY_VERSION = all but the last digit in SHLIBVERSION with .0 appended.
+      Note that the values of the above will be validated. Valid format for either APPLELINK variable is
+      X[.Y[.Z]] where 0 <= X <= 65535, 0 <= Y <= 255, 0 <= Z <= 255.
+      The new variables have been added to the documents and should show up in user guide and manpage.
+    - Fix GH Issue #3136 no longer wrap io.{BufferedReader,BufferedWriter,BufferedRWPair,BufferedRandom,TextIOWrapper
+      with logic to set HANDLE_FLAG_INHERIT flag on the file handle.  Python 3.4+ automatically sets this according
+      to Python docs: https://docs.python.org/3/library/os.html#fd-inheritance
+
+  From Ray Donnelly:
+    - Fix the PATH created by scons.bat (and other .bat files) to provide a normalized
+      PATH.  Some pythons in the 3.6 series are no longer able to handle paths which
+      have ".." in them and end up crashing.  This is done by cd'ing into the directory
+      we want to add to the path and then using %CD% to give us the normalized directory
+      See bug filed under Python 3.6: https://bugs.python.org/issue32457.
+      Note: On Win32 PATH's which have not been normalized may cause undefined behavior
+      by other executables being run by SCons (or any subprocesses of executables being run by SCons).
+      Resolving this issue should eliminate that possibility going forward.
+
+  From Andrew Featherstone
+    - Removed unused --warn options from the man page and source code.
+
+  From Arda Fu
+    - Fix cpp scanner regex logic to treat ifndef for py3.5+. Previously it was
+      not properly differentiating between if, ifdef, and ifndef.
+
+  From Philipp Maierhöfer
+    - Added a __hash__ method to the class Scons.Subst.Literal. Required when substituting Literal
+      objects when SCons runs with Python 3.
+    - Added missing FORTRANMODDIRPREFIX to the gfortran tool.
+
+  From Matthew Marinets:
+    - Fixed an issue that caused the Java emitter to incorrectly parse arguments to constructors that
+      implemented a class.
+
+  From Fredrik Medley:
+    - Fix exception when printing of EnviromentError messages.
+      Specifically, this fixes error reporting of the race condition when
+      initializing the cache which error previously was hidden.
+
+  From Daniel Moody:
+    - Updated Jar builder to handle nodes and directories better
+    - Updated Jar builder to flatten source list which could contain embedded lists
+    - Removed some magic numbers from jar.py on behalf of Mats Wichmann (mats@linux.com)
+    - Set the pickling protocal back to highest which was causing issues
+      with variant dir tests. This will cause issues if reading sconsigns
+      pickled with the previous lower protocal.
+    - Updated swig to setup default paths for windows
+    - Updated gettext tools to setup default paths for windows with Cygwin/MinGW setups
+    - Add common location for default paths for cygwin and mingw in Platform modules
+    - Updated YACC tool to work on windows with Cygwin/MinGW setups
+    - Set the pickling protocal back to highest which was causing issues
+      with variant dir tests. This will cause issues if reading sconsigns
+      pickled with the previous lower protocal.
+    - Updated FS.py to handle removal of splitunc function from python 3.7
+    - Updated the vc.py to ignore MSVS versions where not compiler could be found
+
+  From Gary Oberbrunner:
+    - Fix bug when Installing multiple subdirs outside the source tree
+    - fix to_str to handle None without raising exception
+    - Fix -jN for python 3.7
+
+  From Jonathon Reinhart:
+    - Replace all instances of `int main()` in C code with `int main(void)`.
+      Specifically, this fixes the test cases use by Configure.CheckCC() which
+      would fail when using -Wstrict-prototypes.
+
+  From Zachary Tessler:
+    - Fix calculation of signatures for FunctionActions that contain list (or set,...)
+      comprehensions whose expressions involve constant literals. Those constants had
+      been ignored in signatures, so changing them did not cause targets to be rebuilt.
+
+  From Paweł Tomulik:
+    - In the testing framework, module TestCommon, fixed must_contain(),
+      must_not_contain(), and related methods of TestCommon class to work with
+      substrings located at zero offset.
+    - Added virtualenv support. A new function Virtualenv() determines whether
+      SCons runs in a virtualenv. The search PATH may also be extended to
+      prefer executables from the current virtualenv over the ones provided by
+      base environment. New option --enable-virtualenv provided to import some
+      virtualenv-related variables to SCons and extend every env['ENV']['PATH']
+      automatically. New option --ignore-virtualenv disables this. Two
+      environment variables, SCONS_ENABLE_VIRTUALENV and
+      SCONS_IGNORE_VIRTUALENV are supported for the same purpose.
+
+  From Richard West:
+    - Add SConstruct.py, Sconstruct.py, sconstruct.py to the search path for the root SConstruct file.
+      Allows easier debugging within Visual Studio
+    - Change setup.py to change the install directory (via  pip, or setup.py install) from scons-#.#.#
+      to scons (Yielding <pythondir>/lib/scons/SCons/ instead of <pythondir>/lib/scons/SCons-#.#.#/).
+      This changes SCons to better comply with normal Python installation practices.
+
+  From Mats Wichmann:
+    - Recognize new java 9, 10, 11 (as 9.0 and 10.0, 11.0)
+    - Updated manpage scons.xml to fix a nested list problem
+    - Updated doc terminiology: use prepend instead of append as appropriate
+    - XML validity fixes from SConstruct.py change
+    - Update wiki links to new github location
+    - Update bug links to new github location
+    - Make it easier for SConscript() call to fail on missing script.
+      It was possible to call SCons.Warnings.warningAsException
+      (not documented as a user API) to make all warnings fail. Now
+      SConscript can take an optional must_exist flag which if true fails
+      if the script does not exist.  Not failing on missing script is
+      now considered deprecated, and the first instance will print a
+      deprecation message.  It is now also possible to flip the scons
+      behavior (which still defaults to warn, not fail) by calling
+      SCons.Script.set_missing_sconscript_error, which is also not a
+      documented interface at the moment.
+    - Convert TestCmd.read to use with statement on open (quiets 17 py3 warnings)
+    - Quiet py3 warning in UtilTests.py
+    - Fix tests specifying octal constants for py3
+    - Fix must_contain tests for py3
+    - RPM package generation:
+       - Fix supplying a build architecture
+       - Disable auto debug package generation on certain rpmbuild versions
+       - Adjust some tests to only supply build-id file on certain rpmbuild versions
+       - Tests now use a file fixture for the repeated (trivial) main.c program.
+       - Document and comment cleanup.
+       - Added new Environment Value X_RPM_EXTRADEFS to supply custom settings
+         to the specfile without adding specific logic for each one to scons.
+    - The test for Python.h needed by swig tests is moved to get_python_platform
+      so it does not have to be repeated in every test; picks up one failure
+      which did not make the (previously needed) check. Windows version
+      of get_python_platform needed some rework in case running in virtualenv.
+    - If test opens os.devnull, register with atexit so file opens do not leak.
+    - Fix bugs in Win32 process spawn logic to handle OSError exception correctly.
+    - Use time.perf_counter instead of time.clock if it exists.
+      time.clock deprecated since py3.3, due to remove in 3.8. deprecation
+      warnings from py3.7 were failing a bunch of tests on Windows since they
+      mess up expected stderr.
+    - Prefer Py3's inspect.getfullargspec over deprecated inspect.getargspec.
+      Switched to "new" (standard in Py2.7) usage of receiving a namedtuple -
+      we were unpacking to a four-tuple, two of the items of which were unused;
+      getfullargspec returns a named tuple with seven elements so it is a
+      cleaner drop-in replacement using the namedtuple.
+    - Updated the test-framework.rst documentation.
+    - Remove obsoleted internal implementaiton of OrderedDict.
+    - Test for tar packaging fixups
+    - Stop using deprecated unittest asserts
+    - messages in strip-install-dir test now os-neutral
+    - Add xz compression format to packaging choices.
+    - Syntax cleanups - trailing blanks, use "is" to compare with None, etc.
+      Three uses of variables not defined are changed.
+    - Some script changes in trying to find scons engine
+    - Update (pep8) configure-cache script, add a --show option.
+    - Fix for a couple of "what if tool not found" exceptions in framework.
+    - Add Textfile/Substfile to default environment. (issue #3147)
+    - sconsign: a couple of python3 fixes; be more tolerant of implicit
+      entries which have no signatures; minor PEP8 changes.
+    - Fix a couple of type mistakes (list-> string, filter type -> list)
+    - Fix a couple of type mistakes in packaging tools: list-> string in msi,

   From Daniel Moody:
     - Jar can take multiple targets, and will make a duplicate jar from the sources for each target
     - Added some warnings in case the Jar builder makes an implicit target
     - Added Jar method and changed jar build to be more specific. Jar method will take in

+  From Daniel Moody:
     - Updated the Jar Builder tool in Tool/__init__.py so that is doesn't force class files as
       sources, allowing directories to be passed, which was causing test/Java/JAR.py to fail.
 
+  From William Deegan:
+    - Fix issue where code in utility routine to_String_for_subst() had code whose result was never
+      properly returned.
+      (Found by: James Rinkevich https://pairlist4.pair.net/pipermail/scons-users/2017-October/006358.html )
+    - Fixed Variables.GenerateHelpText() to now use the sort parameter. Due to incorrect 2to3 fixer changes
+      8 years ago it was being used as a boolean parameter.  Now you can specify sort to be a callable, or boolean
+      value. (True = normal sort). Manpage also updated.
+    - Fixed Tool loading logic from exploding sys.path with many site_scons/site_tools prepended on py3.
+    - Added additional output with time to process each SConscript file when using --debug=time.
+
+  From Thomas Berg:
+    - Fixed a regression in scons-3.0.0 where "from __future__ import print_function" was imposed
+      on the scope where SConstruct is executed, breaking existing builds using PY 2.7.
+
+  From William Deegan:
+    - Fix broken subst logic where a string with "$$(abc)" was being treated as "$(abc) and the
+      logic for removing the signature escapes was then failing because there was no closing "$)".
+      This was introduced by a pull request to allow recursive variable evaluations to yield a string
+      such as "$( $( some stuff $) $)".
+
   From Zachary Tessler:
     - Fix incorrect warning for repeated identical builder calls that use overrides
