Currently using OctoberCMS for a new project - loving it so far!

However, I want to make sure I'm not painting myself into a corner - are there browsers I should expect issues with for frontend users? Is there any central resource for understanding which browsers have trouble with certain aspects of octoberCMS?

I'm wondering how much of the ajax components I can utilize without fear for instance.

Thanks!

October currently uses jQuery v2.1.3, which means that you won't have support for IE 7 & 8. You might be able to get away with using the 1.x branch, but I haven't tried this so I have no idea if it will work. If it doesn't, you should still be able to make a site with vanilla javascript, you just won't be able to utilize the ajax library.

But really though, you should drop support for all of those browsers. Microsoft has recently announced end of life for IE 8, 9, and 10, so these browsers won't even be receiving security updates anymore. Tell your users to get with the times, and everyone will be better off :)
