This is a minor patch release that fixes several small issues that are unlikely to manifest in practice:
- Use umask() with mkstemp() to ensure that temporary files are created with correct permissions. This addresses the potential security problem, but creates another, because umask() is not thread safe. For this and other reasons (see #52), file extraction will be removed in a future release.
- Fix copying hook_response_complete instead of hook_transaction_complete.
- Fix several small memory leaks that occur when memory allocation fails.
