As work on new version slowly continues, I've abandoned support for browsers that don't support canvas and added support for mobile devices (now I have means of testing it properly). It will take a while until new interface is on beta website. That means no more IE compatibility, but I'm not really worried because currently only 15-16% of visitors use IE.
Current beta browser requirements: any modern browser with javascript enabled. Browsers that support canvas show full editor, IE users have gimped version that works.
Browser requirements for upcoming version: any modern browser with javascript enabled that supports canvas, rounded corners (optional) and multiple backgrounds. That means:
- IE: none, it is still in stone age.
- Firefox: 3.6 or newer.
- Opera: 10.5 (not released yet. pre-alpha is
available on opera website) or newer.
- Safari, Chrome: any version.
IE users will be asked to install Chrome Frame plugin (which replaces IE rendering engine with Google Chrome) or switch to a different browser, Firefox/Opera users will be asked to upgrade.
