I think Gears was deprecated too soon. Hopefully Google will continue to support it and keep it working for a while longer until the similar features in HTML5 get sorted out, fully implemented and established.
For example, the need is for a local database and an offline app cache. The HTML5 Web SQL Database spec appears to be dead. [ http://dev.w3.org/html5/webdatabase/ ] This was implemented in Chrome and Safari I think, will it continue to be supported in future versions or will it end up being deprecated since it is not part of the html5 spec? It likely won't be implemented in Firefox or IE. IndexedDB is not fully implemented yet. [ http://en.wikipedia.org/wiki/Comparison_of_layout_engines_(HTML_5)#Related_specifications ] This appears to be the HTML5 database spec going forward. This is probably the one to use for a local db, but not quite yet? It looks like IE9/Firefox,/Chrome will support it. For offline app cache, IE/Trident is a 'no' on the Wikipedia chart. That's a problem if your customers use IE. You'd need to use Google Chrome Frame in IE to get offline app functionality. Will Google Chrome Frame continue to be supported for IE9, or only for IE6,7,8? On Feb 3, 4:38 pm, Michael Nordman <gears.team.micha...@gmail.com> wrote: > Gears has been deprecated.
