Support For SeaMonkey 1.x Dropped

In January 2006, SeaMonkey 1.0 was released, a 1.1 release followed a year later. Another three years later, the SeaMonkey project is discontinuing support for the SeaMonkey 1.x series today in favor of SeaMonkey 2.0, which is not only more modern, but also maintained for stability and security problems.

As the SeaMonkey 1.x series no longer receives security updates, due to resource constraints, the SeaMonkey team strongly urges users of that series to upgrade. Additionally, the team continues to strongly urge people still using the old Mozilla Suite or Netscape 4, 6 or 7 to upgrade to the new SeaMonkey 2.0 version. All these older software packages suffer from a large, and steadily increasing, number of security vulnerabilities because they are no longer being maintained.

Everyone on reasonably modern operating systems is urged to switch to the newest release available for free download from the open source project's website at www.seamonkey-project.org, providing the familiar suite functionality in a remodernized application with additional features and fully up to date security.
For the few who can't afford that, a last 1.x release is available. SeaMonkey 1.1.19 does fix a few security issues, but not all known security vulnerabilites, some of which may even be grave. Those are only fixed in the new SeaMonkey 2.0, which will continue to be maintained for quite some time and updated for any security issues as they might arise, while the team is working on evolving the well-known suite even further in future versions.
