Software update: Opera 10 build 1551 beta 1

Opera has been developing the next generation of its web browser of the same name for some time and has now released its first beta release. The version number of this so-called ‘development snapshot’ is 10.0 build 1551. Opera is free to use and includes features such as tabbed browsing, a popup blocker and an email program with spam filter. Updates can be retrieved automatically if DownloadAllSnapshots is enabled in the configuration. This also applies to upgrading from version 9.6x, although backing up the configuration is still recommended. Below you will find everything that has changed since the previous snapshot:

Unix support
On the Linux/Unix front, we are discontinuing support for builds made with gcc 2.95. Also, Sparc Solaris builds are now made on Solaris 10 (with gcc 3) – they should run on Solaris 9 as well. If these changes affect you, we’d love to hear your feedback.
