Usenet Explorer 5.9.1 changelog

Usenet Explorer 5.9.1 brings the following changes:

- Updated downloadable wildmat filter capabilities.

- Fixed a memory leak in the unrar related code incidentally discovered during the development which, it appears, didn't have noticeable manifestations.

- Refined memory allocation method for the time consuming unpack tasks which will play more important role in the future releases.
