A new version of the popular email client Thunderbird has come out. Despite its free status, the program has all the tools for convenient work with mail: spam filtering system, ability to read news through RSS, the opportunity to sort messages into folders based on a variety of criteria such as date, sender, etc.
In addition Thunderbird implements a system of virtual folders, such as that in The Bat.
This version corrects seven errors in the security system, two of which being considered critical.
