# Version 4.2.8

Version 4.2.8 of mod_wsgi can be obtained from:

## Known Issues

1. The makefiles for building mod_wsgi on Windows are currently broken and need updating. As most new changes relate to mod_wsgi daemon mode, which is not supported under Windows, you should keep using the last available binary for version 3.X on Windows instead.

## Bugs Fixed

1. Disable feature for dumping stack traces on daemon process shutdown when a timeout occurs when using Python prior to 2.5. This is because the C API functions are not available in older Python versions.

2. If using Python 3.4 the minimum MacOS X version you can use is 10.8. This needs to be inforced as Apache Runtime library has a definition in header files which changes sizes from 10.7 to 10.8 and trying to compile for compatability back to 10.6 as Python 3.4 tries to enforce, will cause mod_wsgi daemon mode processes to crash at runtime.

3. Python 3.3+ pyvenv style virtual environments would not work with mod_wsgi via the `WSGIPythonHome` directive or the `home` option to the `WSGIDaemonProcess` directive. This is because the support in Python for pyvenv will not work with embedded systems which set the equivalent of `PYTHONHOME` via the Python C API.

The underlying problem in Python is described in issue:

of the Python issue tracer.

To support both normal virtualenv style virtual environments and pyvenv style virtual environments, the manner in which virtual environments are setup by mod_wsgi has been changed. This has at this point only been done on UNIX systems however, as it isn’t known at this point whether the same trick will work on Windows systems.
