This announcement highlights only the important changes. + Please note the following important changes since release 3.0.4: + - Change the default for AppendENVPath to delete_existing=0, so path + order will not be changed, unless explicitly set (Issue #3276) + - Add lex construction variable LEXUNISTD for turning off unix headers on windows + - Update lex tool to use win_flex on windows if available + - Add the textfile tool to the default tool list + - The mingw tool now respects SHCCCOMSTR, SHLINKCOMSTR and LDMODULECOMSTR + - Add support for finding vswhere under 32 bit Windows installs + + + Please note the following important changes since release 3.0.3: + - Added TEMPFILESUFFIX to allow user to specify suffix for tempfiles used for long command lines + - Initial support for ARM architectures with Microsoft Visual Studio 2017. You must set TARGET_ARCH + to arm or arm64 to enable. + - Fixed issue detecting installs of Microsoft Visual Studio 2017 as well as Microsoft build tools 2017. + Please note the following important changes since release 2.5.1: - *IT IS NOT READY FOR PRODUCTION USE* This is the initial release supporting both python 3.5+ and 2.7.x and pypy There are some important changes: - - Any print statements must now use python 3 syntax of "print()" + - 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. + - 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. + - Add flag must_exist to SConscript() call to fail on missing script. + Not failing on missing script is now considered deprecated, and the first instance will print a + deprecation message. + - Add xz compression format to packaging choices. + - Add Textfile/Substfile to default environment. (issue #3147) + - Remove long deprecated SCons.Options which have been replaced by *Variable() + many years ago. + - 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) + - 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. + - Recognize new java 9, 10, 11 (as 9.0 and 10.0, 11.0) - All node content should be in bytes.
