Greetings to everyone.
MiniBB follows its updating plan for 2017, and we start from the new layout regarding the 
new engine version, a 
new website, and a 
new logo. Right now the 
miniBB website comes in responsive mode, and it could be easily accessed both by desktop computers and mobile devices. Besides of it, it should be mobile friendly by Google.
Forums are released in the 
mobile friendly version as well. At least, they are now this way interpreted by the 
Google tool. Despite of it, while working out the new miniBB release, I've come to a new idea of how to implement the 
truly mobile version of forums. The updated templates and codes set is the task I hope to work out this month.
Regarding the update of your current forum, you should not be in hurry for it right now, however it's possible to get some clue from the 
Updating History file or 
package on what's happening and what's going to happen. Look below at the bottom line of this file for the new version notes.
You could also download and install the upcoming 
miniBB version 3.3 Beta 1.
I'm almost sure this release should be stable, as no major functionality was added to it, no critical security fixes, just a lot of layout changes, CSS changes, and some markup changes. This all is done for more easier adjustment of miniBB to any existing website layout, and it is done with the plan of adjust it to the 
Adobe Kuler project. It also tries to follow the modern trends and now aligns to the 
Google Fonts (which is, of course, still optional, and miniBB still could run with any default web fonts defined in CSS).
So, as soon as the mobile version is ready, and as soon all add-ons are adopted with the new version, I will make the generic switch to the "Stable" release of this version.
By now, consider the new look, and post any notes regarding whatever wrong you may discover on the new website.
Also, I will post every new update associated with this release, to this thread.
Enjoy your days! :)
