It's Opera Mini 25 going on Google Play & also Opera Mini beta 25 is available & I'm pretty sure that developers are planning for version 26 beta release but why things are getting so Backdated?? In this forum, Opera Mini thread stuck with "Opera Mini 23 Release" In Opera Mini Repository from Opera. Content stuck with Opera Mini 22. ( http://www.opera.com/mobile/download/versions/ ) In Wikipedia, there's also showing the latest one is Opera Mini 22 ( https://en.m.wikipedia.org/wiki/Opera_Mini ) Moreover, There's no new article posted in Opera Blogs regularly.. At least, the download repository is always needed. Please, make sure its got updated regularly.
Also, there's no new features in Opera Mini since many days. The new features implementation is also stuck. Seems, funny !!!!!!!!!!
