SeaMonkey 2.0 Alpha 1 / 1.1.12

SeaMonkey is a web-browser, advanced e-mail and newsgroup client, IRC chat client, and HTML editor. All inside one application.
The SeaMonkey project is a community effort to deliver production-quality releases of code derived from the application formerly known as "Mozilla Application Suite".
Whereas the main focus of the Mozilla Foundation is on Mozilla Firefox and Mozilla Thunderbird, our group of dedicated volunteers works to ensure that you can have "everything but the kitchen sink", and have it stable enough for corporate use.

System requirements:
- PowerPC processor (266 MHz or faster recommended)
- 64 MB RAM
- 100 MB of free hard disk space (significantly less space is required if you reduce the cache size)

Enhancements:
- SeaMonkey switched to Toolkit, the same backend Firefox uses internally. Due to this change SeaMonkey is now much closer to Firefox as far as user profiles, add-ons and functionality of user interface elements are concerned.
- The default location of user profiles has changed. Legacy profiles, e.g. from SeaMonkey 1.x, are migrated automatically, excluding third-party add-ons (extensions and themes). The old profile will not be touched (instead, copies are made).
- The new Add-on Manager allows to install, update, disable and remove extensions (add-ons), themes and plugins using the same mechanisms Firefox uses. This should ease extension management and development considerably.
- Gecko, the rendering engine used in SeaMonkey, has seen many improvements since the version used in the last stable release. Changes range from a better graphics backend (Cairo/Thebes) to improved support for fonts, CSS, DOM and JavaScript. SeaMonkey 2.0 Alpha 1 passes the Acid2 test and most of Acid3.
- Most of the icons in the default theme have been exchanged for newer images that fit better with the look of modern desktop environments.
- Support for Windows 95, 98, Me and NT 4 was dropped. GTK 2.10 is now required on Linux/UNIX. Support for Mac OS X 10.3 ("Panther") was also dropped.
