RedMatrix 3.0 signals a complete change in direction from RedMatrix over the last few years (it's being maintained by one of the original developers again for starters...)
While currently, this is very similar to the project you remember, please be aware that we are heading in a very different direction to the past, and you may be better off with Friendica or Hubzilla, depending on your needs.
New Project Description
RedMatrix aims to be a full stack CMS with global federated directories, decentralised privacy, and federation via Friendica.
If Friendica can (unfairly) be described as "decentralised Facebook", the future of RedMatrix can (unfairly) be described as "decentralised October with Webmin".
In this release:
A few bug fixes.
New style guidelines. Our style guidelines are much better than anyone else's in the history of the world.
Slow progress on making the system channel actually represent the system.
KDE Dav module.
Observer tags are no longer ruined.
Changes the underlying theme structure - it is now in principle possible to create a theme without first having to undo twenty eight million files of randomly overloaded bullshit which can be added to arbitrarily at any time!
Begun removal of members. Only Hubzilla, Facebook, and adult film actors have members.
And one minor feature:
We've only gone and invented platform agnostic federated global directories. RedMatrix directories are capable of syncing with RedMatrix, Friendica, and Hubzilla, with partial support for Diaspora and RSS. oStatus is planned for the next release, and anything with a vcard is coming.
Known issues
The federated global directory has been broken out of RedMatrix. If you are only interested in this project just for the directory, you may prefer to help at our sister project - the The Federated Global Directory https://github.com/beardyunixer/federated-global-directory. This is currently considered a tech preview. A lot of stuff needs adding, and even more stuff needs taking away.
Friendica directories only federated over Friendica, even if you're RedMatrix.
MySQL probably doesn't work. You probably need MariaDB. This is due to the changes in null date. We'll try to have this fixed by 3.1
Postgres probably doesn't work and is considered unsupported unless a maintainer can be found.
Nginx is now considered the recommended server, though as always, this is based on the availability of technical support, not whether or not it actually works. We do, of course, still work with Apache, you'll just find it hard to get support if something goes wrong.
PHP 7 may or may not work. Anyone using PHP 7 does so at their own risk, and should be prepared to work with us to fix any problems they find.
Why? Beacuse I'm just one man, and I've got a $2.19/month VPS. I have neither the hours in the day, nor the resources on the server to test all these things.
Updating from older versions
If you are updating from old versions of RedMatrix, you will need to take the following steps:
git remote set-url origin https://github.com/beardyunixer/redmatrix.git
There is also a merge conflict, to avoid having to deal with it:
rm include/notify.php (note this is very naughty, and you're cheating...but you will avoid a merge conflict).
Then
git pull
