Software update: Transmission 2.90

After a long time of silence, a new version of Transmission has appeared again. This torrent client uses few resources, is cross-platform and open source, and has a simple and uncluttered interface. The program was developed for use with OS X, but on the download page versions for Linux, Solaris, FreeBSD and some NAS systems are also available. In addition, there is also an unofficial Windows port. In version 2.90, the following changes and improvements have been made:
