Mozilla Thunderbird 2.0.0.4 was released on Thursday 14th June. This update to the Mozilla Corporation's mail client includes bug fixes but no new features. For the first time, this release of Thunderbird is available in Korean.

The Thunderbird 2.0.0.4 section of the Mozilla Foundation Security Advisories page includes details about the security flaws fixed in this release while The Rumbling Edge has a complete Thunderbird 2.0.0.4 changelog. More general details can be found in the Thunderbird 2.0.0.4 Release Notes.

This is the first minor update to Thunderbird 2 since the launch of Thunderbird 2.0.0.0 in April; the version number was selected to match that of the latest Mozilla Firefox release.

The older Thunderbird 1.5 will continue to be supported until Thursday 18th October this year. Thunderbird 1.5.0.12 was released last month with the same security fixes as 2.0.0.4.

While Thunderbird 2.0.0.4 can be downloaded from the Thunderbird product page, most existing Thunderbird 2 users will have received it via the software update mechanism built in to the program.
