The Mozilla Foundation has released Thunderbird v1.5.0.4 for multiple platforms, including Mac OS X. Thunderbird is a free e-mail client and newsreader.
Thunderbird supports IMAP and POP mail protocols, works with HTML-formatted mail and supports Really Simple Syndication (RSS). It features quick search, on-the-fly spell checking, junk mail filters, anti-phishing protection, advanced security and more.
New to this release is Universal Binary support to let Thunderbird run natively on Intel or PowerPC-based Macs. “Thunderbird supports the enhancements to performance introduced by the new MacIntel chipsets,” wrote the developers.
Improvements have also been made to product stability along with several security fixes — some of the security enhancements made in this new release are shared with another recently updated Mozilla product, Firefox.
System requirements call for Mac OS X v10.2 or later, G3 or better processor, 128MB RAM and 4GB hard disk space.
