We currently have a tag for Tor Browser Bundle, but I wonder if we should change this to just Tor Browser instead now that Vidalia is no longer "bundled" in.
Isn't "Tor Browser" now the official name?
It's true that we are heading towards having the name changed to Tor Browser everywhere. Mike Perry opened a ticket almost two years ago after the packages names were changed. Mike suggested to Change Tor Browser Bundle to Tor Browser in package strings, download pages, and docs.
However the reality is that even though a lot of work has been done to update the documentation on the Tor website, there are still many uses of Tor Browser Bundle where Tor Browser is intended. This is both in documentation on the Tor website and on other sites, take for example this fairly recent guide posted on the EFF's Surveillance Self-Defense website. In this example there is only a single occasion where Tor Browser Bundle is used interchangeably but there are plenty of other less reputable websites newcomers to Tor may be visiting for information that frequently use Tor Browser Bundle interchangeably, either because they are out of date or just inaccurate generally. Having said all that, I don't know whether it actually matters that other documentation still uses the terms interchangeably.
A final point to make is that the Tor Blog still tags releases of Tor Browser with the Tor Browser Bundle tag (as well as Tor Browser and TBB) so we would be ahead of the Tor Blog if we get rid of the Tor Browser Bundle tag.
Personally, I don't have a problem with the tag being changed.
