2.1 Alpha 2 Roundup

So, now that the distraction has come to an end (congratulations, Spain!), back to business. SeaMonkey (and Thunderbird) trunk has been broken for the last week or so due to the XPCOM components registration changes. The tree is still closed, but it looks much better now than in the past few days. Time to add some more SeaMonkey 2.1 features!

Upcoming:

• Places-based bookmarks
• Lightweight Themes (Personas)
  
• Data Manager
  

Otherwise, SeaMonkey 2.1 Alpha 2 has been released. The following is an overview of noteworthy changes contained in that release. Also have a look at the Firefox 4 Beta 1 release notes for some more platform changes.

Notable Changes:

• The Add-on Manager has been rewritten and now opens within a new tab or browser window. Read Mossop's blog for more information.
• The video back-end now supports WebM/VP8 (use yasm if compiling on Linux!).
  
• The Troubleshooting Information page (about:support), which features a short-hand for accessing your profile folder, can now be opened from the Help menu (not the Tools menu, as mentioned in the 2.1 Alpha 1 Roundup).
• The Download Manager now allows your to drag files and URLs to and from it, e.g. to the desktop or Explorer window.
• The View Source window includes a Find Bar now, like the one in the Help viewer and Firefox, but at the top of the window.
  
• The MailNews components now supports saving multiple messages as individual files in a directory.
• The MailNews thread pane and other trees now feature alternating backgrounds on Mac and Linux.
  
• The MailNews Search toolbar is gone, in favor of elements that can be used in customizable toolbars. The bar might eventually return (cf. Thunderbird's Quick Filter bar), but for now its elements have been moved to an own, full-sized toolbar (which can of course be disabled and all its elements be moved to other toolbars).
• The Search and Go browser buttons are customizable now, too.
  
• Gopher is gone.
