opera 6.06 security update
Companies that listen to their customers deserve recognition. Opera had decided not to release a security fix to Opera 6.05 after fixing the issue in 7.03. When they found out that people were interested in updating their older version instead of going to 7.03, they released 6.06 (download) with the fix. (via webmaster world)
It is indeed nice when you do not have to always keep updating versions a la microsoft
