eMule is a filesharing client which is based on the eDonkey2000 network but offers more features than the standard client

This version is mainly a security update for 2 severe issues: A security issue in zlib 1.2.2 was found, which is used by eMule and can at least be used to crash eMule. A second bug allows to crash eMule clients with a malformed Kad-Packet (only if Kad is enabled)
We recommend to upgrade to 0.46c as soon as possible.
