Nuitka Release 0.5.4
This is to inform you about the new stable release of Nuitka. It is the extremely compatible Python compiler, “download now”.
This release is aiming at preparatory changes to enable optimization based on SSA analysis, introducing a variable registry, so that variables no longer trace their references to themselves.
Otherwise, MinGW64 support has been added, and lots of bug fixes were made to improve the compatibility. Using new variable registry, now properly detecting actual need for sharing variables. Optimization may discover that it is unnecessary to share a variable, and then it no longer is. This also allows Scons startup has been accelerated, removing scans for unused tools, and avoiding making more than one gcc version check. Compatibility: In case of unknown encodings, Nuitka was not giving the name of the problematic encoding in the error message. Fixed in 0.5.3.3 already. Submodules with the same name as built-in modules were wrongly shadowed. Fixed in 0.5.3.2 already. Python3: Added implementations of Python3.4: Added Python3: Corrections for Fixed crash with Standalone: Need to blacklist Python3: Adapted to changes in Standalone Windows: Preserve Windows: The caching of Scons was not arch specific, and files could be used again, even if changing the arch from Windows: On 32 bit Python it can happen that with large number of generators running concurrently (>1500), one cannot be started anymore. Raising an Added support for MinGW64. Currently needs to be run with Updated internal version of Scons to 2.3.2, which breaks support for VS 2008, but adds support for VS 2013 and VS 2012. The VS 2013 is now the recommended compiler. Added RPM package and repository for RHEL 7. The output of Added option Added option Repository for Ubuntu Raring was removed, no more supported by Ubuntu. Made technical and logical sharing decisions separate functions and implement them in a dedicated variable registry. The Scons file has seen a major cleanup. This release is mostly a maintenance release. The Scons integrations has been heavily visited, as has been Python3 and esp. Python3.4 compatibility, and results from the now possible debug test runs. Standalone should be even more practical now, and MinGW64 is an option for those cases, where MSVC is too slow.Optimization
