Digg says it and Jonathan posted on his blog that Firefox 1.5 is released.
Though we’re able to grab a file dated from November 28th that looks to be a release, no official announcement has been made from the Mozilla Org about Firefox 1.5 officially being released. Even the Mozilla site mozilla.org is stil showing Firefox 1.07 and Firefox 1.5 RC 3 being available for download.
The files accessible through the links posted on these sites are most likely some mirrors which have received the 1.5 version while others are still in the process of synching up.
