This news just came across the pipeline from Google:
We plan to begin phasing out support of these older browsers on the Google Docs suite and the Google Sites editor on March 1, 2010. After that point, certain functionality within these applications may have higher latency and may not work correctly in these older browsers. Later in 2010, we will start to phase out support for these browsers for Google Mail and Google Calendar.
Google Apps will continue to support Internet Explorer 7.0 and above, Firefox 3.0 and above, Google Chrome 4.0 and above, and Safari 3.0 and above.
Starting this week, users on these older browsers will see a message in Google Docs and the Google Sites editor explaining this change and asking them to upgrade their browser. We will also alert you again closer to March 1 to remind you of this change.
In 2009, the Google Apps team delivered more than 100 improvements to enhance your product experience. We are aiming to beat that in 2010 and continue to deliver the best and most innovative collaboration products for businesses.
Thank you for your continued support!
The Google Apps team
While I am always using the latest and greatest version of any browser, I know some of you don’t like to update until you have to and, if you are using the Google products listed above, looks like you finally have to!
On a side note, I am really proud of them for not just going out and being all “Rah Rah Chrome!”
I have to say, having worked at a major dotcom, this is very ballsy of them. Normally, sites bend over backwards for the people using the old browsers for years after they should have upgraded. Google is basically taking the “We are Google. If you want to use us, update already” take which just shows their muscle.
