On August 15th, 2008 October 1, 2008 we will begin phasing out support for Internet Explorer 6 across all 37signals products. In order to continue using the products without any hiccups, Internet Explorer 6 users should upgrade to a newer browser:

Download Internet Explorer 7

Download Firefox

Download Safari

The Internet Explorer 6 browser was released back in 2001, and Internet Explorer 7, the replacement, was released nearly two years ago in 2006. Modern web browsers such as IE 7, Firefox, and Safari provide significantly better online experiences. Since IE 6 usage has finally dipped below a small minority threshold of our customers, it's time to finally move beyond IE 6.

What are the implications of this transition?

As of August 15th, 2008 October 1, 2008, future features and any improvements made to existing features may not work with IE 6. If you are using IE 7, Firefox 2 or 3, or Safari, you don't have to do anything — everything will continue as is for you. However, if you are using IE 6, and you want to make sure everything works, you will need to upgrade your browser to either IE 7, Firefox, or Safari. All of these browsers are free and all of them will deliver a much better overall experience. The web will be a lot better for you.

Special note for people using Basecamp with clients: If your clients are using IE 6 (you'll want to ask them) you may want to provide them some assistance in upgrading their browser.

Why are we making this change?

IE 6 is a last-generation browser. This means that IE 6 can't provide the same web experience that modern browsers can. Continued support of IE 6 means that we can't optimize our interfaces or provide an enhanced customer experience in our apps. Supporting IE 6 means slower progress, less progress, and, in some places, no progress. We want to make sure the experience is the best it can be for the vast majority of our customers, and continuing to support IE 6 holds us back.

Thanks again

Thanks again for your continued support. We look forward to dropping the rusty weight of IE 6 and improving the overall customer experience moving forward.

Updated: We have extended the IE 6 transition from August 15, 2008 to October 1, 2008. We hope this extension gives you additional time to make the necessary arrangements to upgrade your web browsers.
