MyBB 1.2 Release Announcement Wrote:AJAX
It's been requested many, many times and we kept saying "Hold your horses! It's coming!"

MyBB now makes use of the javascript XMLHttp extensions. Included AJAX based functionality includes auto completion and suggestion of usernames whilst composing private messaging, inline thread subject editing and inline post message editing.

Improved RSS and syndication support
We realise that content syndication is a very important technology and we've greatly improved support for it in MyBB. Feeds can now be served as Atom feeds, all data is properly sanitized and validated before being used in feeds and we've also designed a class which can generate an RSS feed from any data you pass to it as well as a class that can parse RSS feeds and return an array of information from them.

New reputation system
The old reputation system in MyBB had some serious flaws (it was very easily abused, votes could not be edited or deleted without diving directly in to MySQL). The folks over at the Messenger Plus! Community Forums addressed this by cleverly designing a reputation system similar to the feedback system of eBay. A similar modification was also written for MyBB called the "Alternative Reputation System" by Smethead (Who I'm very sad to hear is leaving the modifications community). Our new reputation system is based around the ideas and implementations of those two wonderful additions made to MyBB.

You can now only give a reputation to a user once but you can in the future edit or update your reputation of that user. Reputations are also publicly displayed (limits abuse) and can be deleted by administrators.

Multi-quote
A popular feature on other competitors applications is the ability to select multiple posts to be quoted and then on the "New Reply" page, have them loaded automatically in to the message area. We've implemented this in to MyBB - we find it extremely useful and hopefully you do too.

You can also cross quote replies from other threads and then have them loaded in to the message area using AJAX by clicking on a link which states there are external quoted posts.

Full-text searching (and search improvements)
If your database server supports full-text searching in boolean mode then you can switch over to using this amazing functionality which allows users to create complex search queries (along the lines of '"mybb rocks"' or 'example or tester' - and even more amazing). The database server handles the searching and quickly returns sets of results.

Search functionality has also improved overall. Results are now cached after the initial search which means browsing results is now much more efficient.

Improved CAPTCHA images
The CAPTCHA images used when registering have also been improved. They now support slanted and randomly positioned text, random TTF font selection and random characters and symbols in the background.

The same system has also been implemented when guests attempt to make a new post or reply to ensure they're not automated systems (bots)

Thy Admin Wrote:Unfortunately, moving to a completely new development branch (1.2.x, instead of 1.1.x) means all other plugins, as well as the templates and themes, are incompatible with our current version.

In case you wondered: You weren't the first one to ask.
