I'll keep this short... Although we kept the version numbering inside the 2.5.x series, 2.5.5 brings some new uber-cool features:
Smart Search integration for Joomla! 2.5
integration with anti-spam service StopForumSpam.com to stop real, human spam - available upon user sign up and for flagging spammers in comments
native support for jUpgrade (both versions) makes upgrading a Joomla! 1.5 site to 2.5 a piece of cake
integration with the Joomla! updater (v1.7+). Using the built-in extension updater in Joomla! you can check if there's a new K2 release and instantly apply the update
Community Builder integration for user profiles/pages
the K2 Media Manager has been upgraded and now supports image resizing as well! Just drag and drop images from your desktop inside the K2 Media Manager to upload them on your server, then resize and use them anywhere in your Joomla! site. The K2 Media Manager, already a full Joomla! media manager replacement, just got better!
(new) Added support for Falang, the JoomFish fork currently working on Joomla! 1.7 & 2.5 (JoomFish is not yet ready publicly for J2.5 - but that will come soon).
I'm also very proud to announce the the translation teams working on K2 language packs are now 52! Congratulations to all contributors and very big thank you from the K2 team! If you want to track the progress of translations or create a new transation team or join an existing one, check out the K2 project page on Transifex.
K2 version 2.5.5 will be released next week on Friday, March 2nd March 7th 2012. Sorry for the sort delay folks but we decided to add a couple of new features in this release.
We have just released v2.5.3 of K2, fixing primarily minor glitches in 2.5.1 and a small (but significant) JS error that appeared in the short-lived 2.5.2 release (which we issued past Friday). If you are using K2 v2.5.1 you can safely upgrade to v2.5.3 by installing the 2.5.3 zip file on top of 2.5.1. As always, it's good to grab a backup just in case (you can use the free Akeeba Backup for that).
We have just released v2.5.1 of K2, a maintenance release, fixing some minor issues as reported by the K2 Community.
This release maybe "maintenance", but we have gone through some "bigger" changes regarding content setup workflow and frontend editing.
In v2.5.1 we have improved the "friendliness" of frontend editing. E.g. when you edit an item via the frontend and close the editing window, the page will refresh, revealing the applied (or not) changes. Frontend users who don't have "publishing" rights will see a notice displaying at the top of the editing window and they will not see the published/featured controls. Additionally, only users with "editorial" rights (but not necessarily publishing rights), aka users with the permission "can edit any item" in their K2 group, are the ones who can now see and change an item's author. Previously anyone with some editing rights could do that. So all in all, frontend editing is a bit more tied up and informative to your frontend users.
I'm glad that after more than a year of constant development and improvements (and a rock solid v2.4.1), K2 version 2.5.0 is now available to download.
The major upgrade to 2.5.0 is that K2 is now a native Joomla! 1.5, 1.6 and 1.7 extension. But upgrades don't stop there. We have significantly improved performance, measuring up to 500% in complex sites with complex structures and pages with lots of items on them (portals, magazines etc.).
Let's take a closer look at all the changes that version 2.5.0 brings. Sit back, relax and start reading (will take time). :)
What an exciting week for K2! We're rolling out the much anticipated, much improved K2 v2.5 with full Joomla! 1.5 up to 1.7 compatibility, as well as the new home for K2 that you currently see, the new getk2.org!
Although detailed info on the new K2 version will be published soon, with the official release of K2 v2.5 (stable), I'm happy to share with everyone that the new release will continue the legacy of v2.4 as a rock solid content management extension for Joomla!. It took a little over a year of development to get to 2.5 but it was worth it. Improved performance, enhanced features, enhanced workflow, an all-in-all better way to manage your content in Joomla!. Of course, in-between the ever evolving Joomla! v1.6 (and up to today's 1.7) we had to change things and adapt, but now that 1.7 seems to be on track for a successful and stable release for Joomla!, it was time we got the new K2 out as well. Software is an ever evolving process and releases are essentially snapshots of this process. And now is the right time for v2.5 of K2, now that the current release of Joomla! has reached a stable and mature cycle.
