Opera has launched a new version of its browser, 7.50, for Windows, Mac, Linux, FreeBSD and Solaris. Opera 7.50 includes an e-mailer, newsreader, IRC-compatible chat client, contact database and support for RSS newsfeeds. It’s 3.5 megabytes in size (without Java). The interface has been revamped, with a new panel selector. Opera Mail has had a facelift too, including fast content search, a contact database, a newsreader, automatic filtering, and a spellchecker. The chat client is IRC-compatible and supports both private and group chats. The browser is available free of charge with sponsored advertising. An ad-free version costs $40.
