This is to inform you about the new stable release of Nuitka. It is the extremely compatible Python compiler, “download now”.

This release adds a ton of new features and corrections.

Bug Fixes

Standalone: For the “Python Build Standalone” flavor ensured that debug builds correctly recognize all their specific built-in modules, preventing potential errors. (Fixed in 2.7.2 already.)

Linux: Fixed a crash when attempting to modify the RPATH of statically linked executables (e.g., from imageio-ffmpeg). (Fixed in 2.7.2 already.)

Anaconda: Updated PySide2 support to correctly handle path changes in newer Conda packages and improved path normalization for robustness. (Fixed in 2.7.2 already.)

macOS: Corrected handling of QtWebKit framework resources. Previous special handling was removed as symlinking is now default, which also resolved an issue of file duplication. (Fixed in 2.7.2 already.)

Debugging: Resolved an issue in debug builds where an incorrect assertion was done during the addition of distribution metadata. (Fixed in 2.7.1 already.)

Module: Corrected an issue preventing stubgen from functioning with Python versions earlier than 3.6. (Fixed in 2.7.1 already.)

UI: Prevented Nuitka from crashing when --include-module was used with a built-in module. (Fixed in 2.7.1 already.)

Module: Addressed a compatibility issue where the code mode for the constants blob failed with the C++ fallback. This fallback is utilized on very old GCC versions (e.g., default on CentOS7), which are generally not recommended. (Fixed in 2.7.1 already.)

Standalone: Resolved an assertion error that could occur in certain Python setups due to extension module suffix ordering. The issue involved incorrect calculation of the derived module name when the wrong suffix was applied (e.g., using .so to derive a module name like gdbmmodule instead of just gdbm). This was observed with Python 2 on CentOS7 but could potentially affect other versions with unconventional extension module configurations. (Fixed in 2.7.1 already.)

Python 3.12.0: Corrected the usage of an internal structure identifier that is only available in Python 3.12.1 and later versions. (Fixed in 2.7.1 already.)

Plugins: Prevented crashes in Python setups where importing pkg_resources results in a PermissionError. This typically occurs in broken installations, for instance, where some packages are installed with root privileges. (Fixed in 2.7.1 already.)

macOS: Implemented a workaround for data file names that previously could not be signed within app bundles. The attempt in release 2.7 to sign these files inadvertently caused a regression for cases involving illegal filenames. (Fixed in 2.7.1 already.)

Python 2.6: Addressed an issue where staticmethod objects lacked the __func__ attribute. Nuitka now tracks the original function as a distinct value. (Fixed in 2.7.1 already.)

Corrected behavior for orderedset implementations that lack a union method, ensuring Nuitka does not attempt to use it. (Fixed in 2.7.1 already.)

Python 2.6: Ensured compatibility for setups where the _PyObject_GC_IS_TRACKED macro is unavailable. This macro is now used beyond assertions, necessitating support outside of debug mode. (Fixed in 2.7.1 already.)

Python 2.6: Resolved an issue caused by the absence of sys.version_info.releaselevel by utilizing a numeric index instead and adding a new helper function to access it. (Fixed in 2.7.1 already.)

Module: Corrected the __compiled__.main value to accurately reflects the package in which a module is loaded, this was not the case for Python versions prior to 3.12. (Fixed in 2.7.1 already.)

Plugins: Further improved the dill-compat plugin by preventing assertions related to empty annotations and by removing hard-coded module names for greater flexibility. (Fixed in 2.7.1 already.)

Windows: For onefile mode using DLL mode, ensure all necessary environment variables are correctly set for QtWebEngine. Previously, default Qt paths could point incorrectly near the onefile binary. (Fixed in 2.7.3 already.)

PySide6: Fixed an issue with PySide6 where slots defined in base classes might not be correctly handled, leading to them only working for the first class that used them. (Fixed in 2.7.3 already.)

Plugins: Enhanced Qt binding plugin support by checking for module presence without strictly requiring metadata. This improves compatibility with environments like Homebrew or uv where package metadata might be absent. (Fixed in 2.7.3 already.)

macOS: Ensured the apple target is specified during linking to prevent potential linker warnings about using an unknown target in certain configurations. (Fixed in 2.7.3 already.)

macOS: Disabled the use of static libpython with pyenv installations, as this configuration is currently broken. (Fixed in 2.7.3 already.)

macOS: Improved error handling for the --macos-app-protected-resource option by catching cases where a description is not provided. (Fixed in 2.7.3 already.)

Plugins: Enhanced workarounds for PySide6, now also covering single-shot timer callbacks. (Fixed in 2.7.4 already.)

Plugins: Ensured that the Qt binding module is included when using accelerated mode with Qt bindings. (Fixed in 2.7.4 already.)

macOS: Avoided signing through symlinks and minimized their use to prevent potential issues, especially during code signing of application bundles. (Fixed in 2.7.4 already.)

Windows: Implemented path shortening for paths used in onefile DLL mode to prevent issues with long or Unicode paths. This also benefits module mode. (Fixed in 2.7.4 already.)

UI: The options nanny plugin no longer uses a deprecated option for macOS app bundles, preventing potential warnings or issues. (Fixed in 2.7.4 already.)

Plugins: Ensured the correct macOS target architecture is used. This particularly useful for PySide2 with universal CPython binaries, to prevent compile time crashes e.g. when cross-compiling for a different architecture. (Fixed in 2.7.4 already.)

UI: Fixed a crash that occurred on macOS if the ccache download was rejected by the user. (Fixed in 2.7.4 already.)

UI: Improved the warning message related to macOS application icons for better clarity. (Added in 2.7.4 already.)

Standalone: Corrected an issue with QML plugins on macOS when using newer PySide6 versions. (Fixed in 2.7.4 already.)

Python 3.10+: Fixed a memory leak where the matched value in pattern matching constructs was not being released. (Fixed in 2.7.4 already.)

Python3: Fixed an issue where exception exits for larger range objects, which are not optimized away, were not correctly annotated by the compiler. (Fixed in 2.7.4 already.)

Windows: Corrected an issue with the automatic use of icons for PySide6 applications on non-Windows if Windows icon options were used. (Fixed in 2.7.4 already.)

Onefile: When using DLL mode there was a load error for the DLL with MSVC 14.2 or earlier, but older MSVC is to be supported. (Fixed in 2.7.5 already.)

Onefile: Fix, the splash screen was showing in DLL mode twice or more; these extra copies couldn’t be stopped. (Fixed in 2.7.5 already.)

Standalone: Fixed an issue where data files were no longer checked for conflicts with included DLLs. The order of data file and DLL copying was restored, and macOS app signing was made a separate step to remove the order dependency. (Fixed in 2.7.6 already.)

macOS: Corrected our workaround using symlinks for files that cannot be signed. When --output-directory was used, as it made incorrect assumptions about the dist folder path. (Fixed in 2.7.6 already.)

UI: Prevented checks on onefile target specifications when not actually compiling in onefile mode, e.g. on macOS with --mode=app. (Fixed in 2.7.6 already.)

UI: Improved error messages for data directory options by include the relevant part in the output. (Fixed in 2.7.6 already.)

Plugins: Suppressed UserWarning messages from the pkg_resources module during compilation. (Fixed in 2.7.6 already.)

Python3.11+: Fixed an issue where descriptors for compiled methods were incorrectly exposed for Python 3.11 and 3.12. (Fixed in 2.7.7 already.)

Plugins: Avoided loading modules when checking for data file existence. This prevents unnecessary module loading and potential crashes in broken installations. (Fixed in 2.7.9 already.)

Plugins: The global_change_function anti-bloat feature now operates on what should be the qualified names (__qualname__) instead of just function names, preventing incorrect replacements of methods with the same name in different classes. (Fixed in 2.7.9 already.)

Onefile: The containing_dir attribute of the __compiled__ object was regressed in DLL mode on Windows, pointing to the temporary DLL directory instead of the directory containing the onefile binary. (Fixed in 2.7.10 already, note that the solution in 2.7.9 had a regression.)

Compatibility: Fixed a crash that occurred when an import attempted to go outside its package boundaries. (Fixed in 2.7.11 already.)

macOS: Ignored a warning from codesign when using self-signed certificates. (Fixed in 2.7.11 already.)

Onefile: Fixed an issue in DLL mode where environment variables from other onefile processes (related to temporary paths and process IDs) were not being ignored, which could lead to conflicts. (Fixed in 2.7.12 already.)

Compatibility: Fixed a potential crash that could occur when processing an empty code body. (Fixed in 2.7.13 already.)

Plugins: Ensured that DLL directories created by plugins could be at the top level when necessary, improving flexibility. (Fixed in 2.7.13 already.)

Onefile: On Windows, corrected an issue in DLL mode where original_argv0 was None; it is now properly set. (Fixed in 2.7.13 already.)

macOS: Avoided a warning that appeared on newer macOS versions. (Fixed in 2.7.13 already.)

macOS: Allowed another DLL to be missing for PySide6 to support more setups. (Fixed in 2.7.13 already.)

Standalone: Corrected the existing import workaround for Python 3.12 that was incorrectly renaming existing modules of matching names into sub-modules of the currently imported module. (Fixed in 2.7.14 already.)

Standalone: On Windows, ensured that the DLL search path correctly uses the proper DLL directory. (Fixed in 2.7.14 already.)

Python 3.5+: Fixed a memory leak where the called object could be leaked in calls with keyword arguments following a star dict argument. (Fixed in 2.7.14 already.)

Python 3.13: Fixed an issue where PyState_FindModule was not working correctly with extension modules due to sub-interpreter changes. (Fixed in 2.7.14 already.)

Onefile: Corrected an issue where the process ID (PID) was not set in a timely manner, which could affect onefile operations. (Fixed in 2.7.14 already.)

Compatibility: Fixed a crash that could occur when a function with both a star-list argument and keyword-only arguments was called without any arguments. (Fixed in 2.7.16 already.)

Standalone: Corrected an issue where distribution names were not checked case-insensitively, which could lead to metadata not being included. (Fixed in 2.7.16 already.)

Linux: Avoid using full zlib with extern declarations but instead only the CRC32 functions we need. Otherwise conflicts with OS headers could occur.

Standalone: Fixed an issue where scanning for standard library dependencies was unnecessarily performed.

Plugins: Made the runtime query code robust against modules that in stdout during import

This affected at least toga giving some warnings on Windows with mere stdout prints. We now have a marker for the start of our output that we look for and safely ignore them.

Windows: Do not attempt to attach to the console when running in DLL mode. For onefile with DLL mode, this was unnecessary as the bootstrap already handles it, and for pure DLL mode, it is not desired.

Onefile: Removed unnecessary parent process monitoring in onefile mode, as there is no child process launched.

Anaconda: Determine version and project name for conda packages more reliably

It seems Anaconda is giving variables in package metadata and often no project name, so we derive it from the conda files and its meta data in those cases.

macOS: Make sure the SSL certificates are found when downloading on macOS, ensuring successful downloads.

Windows: Fixed an issue where console mode attach was not working in onefile DLL mode.

Scons: Fixed an issue where pragma was used with older gcc gcc can give warnings about them. This fixes building on older OSes with the system gcc.

Compatibility: Fix, need to avoid using filenames with more than 250 chars for long module names.

For cache files, const files, and C files, we need to make sure, we don’t exceed the 255 char limits per path element that literally every OS has.

Also enhanced the check code for legal paths to cover this, so user options are covered from this errors too.

Moved file hashing to file operations where it makes more sense to allow module names to use hashing to provide a legal filename to refer to themselves.

Compatibility: Fixed an issue where walking included compiled packages through the Nuitka loader could produce incorrect names in some cases.

Windows: Fixed wrong calls made when checking stderr properties during launch if it was None.

Debugging: Fixed an issue where the segfault non-deployment disable itself before doing anything else.

Plugins: Fix, the warning to choose a GUI plugin for matplotlib was given with tk-inter plugin enabled still, which is of course not appropriate.

Distutils: Fix, do not recreate the build folder with a .gitignore file.

We were re-creating it as soon as we looked at what it would be, now it’s created only when asking for that to happen.

No-GIL: Addressed compile errors for the free-threaded dictionary implementation that were introduced by necessary hot-fixes in the version 2.7.

Compatibility: Fixed handling of generic classes and generic type declarations in Python 3.12.

macOS: Fixed an issue where entitlements were not properly provided for code signing.

Onefile: Fixed delayed shutdown for terminal applications in onefile DLL mode.

Was waiting for non-used child processes, which don’t exist and then the timeout for that operation, which is always happening on CTRL-C or terminal shutdown.

Python3.13: Fix, seems interpreter frames with None code objects exist and need to be handled as well.

Standalone: Fix, need to allow for setuptools package to be user provided.

Windows: Avoided using non-encodable dist and build folder names.

Some paths don’t become short, but still be non-encodable from the file system for tools. In these cases, temporary filenames are used to avoid errors from C compilers and other tools.

Python3.13: Fix, ignore stdlib cgi module that might be left over from previous installs

The module was removed during development, and if you install over an old alpha version of 3.13 a newer Python, Nuitka would crash on it.

macOS: Allowed the lib folder for the Python Build Standalone flavor, improving compatibility.

macOS: Allowed libraries for rpath resolution to be found in all Homebrew folders and not just lib.

Onefile: Need to allow .. in paths to allow outside installation paths.

New Features

Python3.14: Added experimental support for Python3.14, not recommended for use yet, as this is very fresh and might be missing a lot of fixes.

Release: Added an extra dependency group for the Nuitka build-backend, intended for use in pyproject.toml and other build-system dependencies. To use it depend in Nuitka[build-wheel] instead of Nuitka. (Added in 2.7.7 already.)

For release we also added Nuitka[onefile], Nuitka[standalone], Nuitka[app] as extra dependency groups. If icon conversions are used, e.g. Nuitka[onefile,icon-conversion] adds the necessary packages for that. If you don’t care about what’s being pulled in Nuitka[all] can be used, by default Nuitka only comes with the bare minimum needed and will inform about missing packages.

macOS: Added --macos-sign-keyring-filename and --macos-sign-keyring-password to automatically unlock a keyring for use during signing. This is very useful for CI where no UI prompt can be used.

Windows: Detect when input cannot be used due to no console or the console not providing proper standard input and produce a dialog for entry instead. Shells like cmd.exe execute inputs as commands entered when attaching to them. With this, the user is informed to make the input into the dialog instead. In case of no terminal, this just brings up the dialog for GUI mode.

Plugins: Introduced global_change_function to the anti-bloat engine, allowing function replacements across all sub-modules of a package at once. (Added in 2.7.6 already.)

Reports: For Python 3.13+, the compilation report now includes information on GIL usage. (Added in 2.7.7 already.)

macOS: Added an option to prevent an application from running in multiple instances. (Added in 2.7.7 already.)

AIX: Added support for this OS as well, now standalone and module mode work there too.

Scons: When C a compilation fails to due warnings in --debug mode, recognize that and provide the proper extra options to use if you want to ignore that.

Non-Deployment: Added a non-deployment handler to catch modules

Non-Deployment: Added non-deployment handler to catch modules that error exit on import, while assumed to work perfectly.

This will give people an indication that the numpy module is expected to work and that maybe just the newest version is not and we need to be told about it.

Non-Deployment: Added a non-deployment handler for DistributionNotFound exceptions in the main program, which now points the user to the necessary metadata options.

UI: Made --include-data-files-external the primary option for placing data files alongside the created program.

This now works with standalone mode too, and is no longer onefile specific, the name should reflect that and people can now use it more broadly.

Plugins: Added support for multiple warnings of the same kind. The dill-compat plugin needs that as it supports multiple packages.

Plugins: Added detector for the dill-compat plugin that detects usages of dill, cloudpickle and ray.cloudpickle.

Standalone: Add support for including Visual Code runtime dlls on Windows.

When MSVC (Visual Studio) is installed, we take the runtime DLLs from its folders. We cannot take the ones from the redist packages installed to system folders for license reasons.

Gives a warning when these DLLs would be needed, but were not found.

We might want to add an option later to exclude them again, for size purposes, but correctness out of the box is more important for now.

UI: Make sure the distribution name is correct for --include-distribution-metadata option values.

Plugins: Added support for configuring re-compilation of extension modules from their source code.

When we have both Python code and an extension module, we only had a global option available on the command line.

This adds --recompile-extension-modules for more fine grained choices as it allows to specify names and patterns.

For zmq, we need to enforce it to never be compiled, as it checks if it is compiled with Cython at runtime, so re-compilation is never possible.

Reports: Include environment flags for C compiler and linker picked up for the compilation. Sometimes these cause compilation errors that and this will reveal there presence.

Optimization

Enhanced detection of raise statements that use compile-time constant values which are not actual exception instances.

This improvement prevents Nuitka from crashing during code generation when encountering syntactically valid but semantically incorrect code, such as raise NotImplemented. While such code is erroneous, it should not cause a compiler crash. (Added in 2.7.1 already.)

With unknown locals dictionary variables trust very hard values there too.

With this using hard import names also optimize inside of classes.

This makes gcloud metadata work, which previously wasn’t resolved in their code.

macOS: Enhanced PySide2 support by removing the general requirement for onefile mode. Onefile mode is now only enforced for QtWebEngine due to its specific stability issues when not bundled this way. (Added in 2.7.4 already.)

Scons: Added support for C23 embedding of the constants blob with ClangCL, avoiding the use of resources. Since the onefile bootstrap does not yet honor this for its payload, this feature is not yet complete but could help with size limitations in the future.

Plugins: Overhauled the UPX plugin.

Use better compression than before, hint the user at disabling onefile compression where applicable to avoid double compression. Output warnings for files that are not considered compressible. Check for upx binary sooner.

Scons: Avoid compiling hacl code for macOS where it’s not needed.

Anti-Bloat

Improved handling of the astropy package by implementing global replacements instead of per-module ones. Similar global handling has also been applied to IPython to reduce overhead. (Added in 2.7.1 already.)

Avoid docutils usage in the markdown2 package. (Added in 2.7.1 already.)

Reduced compiled size by avoiding the use of “docutils” within the markdown2 package. (Added in 2.7.1 already.)

Avoid including the testing framework from the langsmith package. (Added in 2.7.6 already.)

Avoid including setuptools from jax.version. (Added in 2.7.6 already.)

Avoid including unittest from the reportlab package. (Added in 2.7.6 already.)

Avoid including IPython for the keras package using a more global approach. (Added in 2.7.11 already.)

Avoid including the triton package when compiling transformers. (Added in 2.7.11 already.)

Avoid a bloat warning for an optional import in the seaborn package. (Added in 2.7.13 already.)

Avoid compiling generated google.protobuf.*_pb2 files. (Added in 2.7.7 already.)

Avoid including triton and setuptools when using the xformers package. (Added in 2.7.16 already.)

Refined dask support to not remove pandas.testing when pytest usage is allowed. (Added in 2.7.16 already.)

Avoid compiling the tensorflow module that is very slow and contains generated code.

Avoid using setuptools in cupy package.

Avoid false bloat warning in seadoc package.

Avoid using dask in sklearn package.

Avoid using cupy.testing in the cupy package.

Avoid using IPython in the roboflow package.

Avoid including ray for the vllm package.

Avoid using dill in the torch package.

Organizational

UI: Remove obsolete options to control the compilation mode from help output. We are keeping them only to not break existing workflows, but --mode=... should be used now, and these options will start triggering warnings soon.

Python3.13.4: Reject broken CPython official release for Windows.

The link library included is not the one needed for GIL, and as such it breaks Nuitka heavily and must be errored out on, all smaller or larger micro versions work, but this one does not.

Release: Do not use Nuitka 2.7.9 as it broke data file access via __file__ in onefile mode on Windows. This is a brown paper bag release, with 2.7.10 containing only the fix for that. Sorry for the inconvenience.

Release: Ensured proper handling of newer setuptools versions during Nuitka installation. (Fixed in 2.7.4 already.)

UI: Sort --list-distribution-metadata output and remove duplicates. (Changed in 2.7.8 already.)

Visual Code: Added a Python 2.6 configuration for Win32 to aid in comparisons and legacy testing.

UI: Now lists available Qt plugin families if --include-qt-plugin cannot find one.

UI: Warn about compiling a file named __main__.py which should be avoided, instead you should specify the package directory in that case.

UI: Make it an error to compile a file named __init__.py for standalone mode.

Debugging: The --edit option now correctly finds files even when using long, non-shortened temporary file paths.

Debugging: The pyside6 plugin now enforces --no-debug-immortal-assumptions when --debug is on because PySide6 violates these and we don’t need Nuitka to check for that then as it will abort when it finds them.

Quality: Avoid writing auto-formatted files with same contents

That avoids stirring up tools that listen to changes.

For example the Nuitka website auto-builder otherwise rebuilt per release post on docs update.

Quality: Use latest version of deepdiff.

Quality: Added autoformat for JSON files.

Release: The man pages were using outdated options and had no example for standalone or app modes. Also the actual options were no longer included.

GitHub: Use the --mode options in the issue template as well.

GitHub: Enhanced wordings for bug report template to give more directions and more space for excellent reports to be made.

GitHub: The bug report template now requests the output of our package metadata listing tool, as it provides more insight into how Nuitka perceives the environment.

Debugging: Re-enabled important warnings for Clang, which had unnoticed for a long time and prevented a few things from being recognized.

Debugging: Support arbitrary debuggers through –debugger-choice.

Support arbitrary debuggers for use in the --debugger mode, if you specify all of their command line you can do anything there.

Also added predefined valgrind-memcheck mode for memory checker tool of Valgrind to be used.

UI: Added rich as a progress bar that can be used. Since it’s available via pip, it can likely be found and requires no inline copy. Added colors and similar behavior for tqdm as well.

UI: Remove obsolete warning for Linux with upx plugin.

We don’t use appimage anymore for a while now, so its constraints no longer apply.

UI: Add warnings for module specific options too. The logic to not warn on GitHub Actions was inverted, this restores warnings for normal users.

UI: Output the module name in question for options-nanny plugin and parameter warnings.

UI: When a forbidden import comes from an implicit import, report it properly.

Sometimes .pyi files from extension modules cause an import, but it was not clear which one; now it will indicate the module causing it.

UI: More clear error message in case a Python for scons was not found.

Actions: Cover debug mode compilation at least once.

Quality: Resolve paths from all OSes in --edit. Sometime I want to look at a file on a different OS, and there is no need to enforce being on the same one for path resolution to work.

Actions: Updated to a newer Ubuntu version for testing, as to get clang-format installed anymore.

Debugging: Allow for C stack output in signal handlers, this is most useful when doing the non-deployment handler that catches them to know where they came from more precisely.

UI: Show no-GIL in output of Python flavor in compilation if relevant.

Tests

Removed Azure CI configuration, as testing has been fully migrated to GitHub Actions. (Changed in 2.7.9 already.)

Improved test robustness against short paths for package-containing directories. (Added in 2.7.4 already.)

Prevented test failures caused by rejected download prompts during test execution, making CI more stable. (Added in 2.7.4 already.)

Refactored common testing code to avoid using doctests, preventing warnings in specific standalone mode test scenarios related to reference counting. (Added in 2.7.4 already.)

Tests: Cover the memory leaking call re-formulation with a reference count test.

Cleanups

Plugins: Improved pkg_resources integration by using the __loader__ attribute of the registering module for loader type registration, avoiding modification of the global builtins dictionary. (Fixed in 2.7.2 already.)

Improved the logging mechanism for module search scans. It is now possible to enable tracing for individual locateModule calls, significantly enhancing readability and aiding debugging efforts.

Scons: Refactored architecture specific options into dedicated functions to improve code clarity.

Spelling: Various spelling and wording cleanups.

Avoid using #ifdef in C code templates, and let’s just avoid it generally.

Added missing slot function names to the ignored word list.

Renamed variables related to slots to be more verbose and proper spelling as a result, as that’s for better understanding of their use anyway.

Scons: Specify versions supported for Scons by excluding the ones that are not, rather than manually maintaining a list. This adds automatic support for Python 3.14.

Plugins: Removed a useless call to intern as it did not have thought it does.

Attach copyright during code generation for code specializations

This also enhances the formatting for almost all files by making leading and trailing new lines more consistent.

One C file turns out unused and was removed as a left over from a previous refactoring.

Summary

This release was supposed to focus on scalability, but that didn’t happen again due to a variety of important issues coming up as well as a created downtime after high private difficulties after a planned surgery. However, the upcoming release will have it finally.

The onefile DLL mode as used on Windows has driven a lot of need for corrections, some of which are only in the final release, and this is probably the first time it should be usable for everything.

For compatibility, working with the popular (yet - not yes recommended UV-Python), Windows UI fixes for temporary onefile and macOS improvements, as well as improved Android support are excellent.

The next release of Nuitka however will have to focus on scalability and maintenance only. But as usual, not sure if it can happen.
